There's a (fairly crude) demo at: http://www.otherleg.com/games/mapGame_new/mapGame.svg (use wasd to move around) Please use event.preventDefault() on the keyevents you handle. My intention is that players can login and create their own areas of the world. It'd be nice if people don't have to enter their username and password every time they go there. It appears, however, that cookie creation isn't supported in ECMAScript. Oh? That should work AFAIK. And if the browser is html5-enabled, then document.cookies should work in svg and html documents alike, and you should be able to get/set cookies via that interface. See https://developer.mozilla.org/en/document.cookie. What do people do in this kind of circumstance? I was thinking perhaps: - embed the svg in some html - use the html to get login details and set cookies - html script starts an svg ecma script on successful login. However, I'm not sure how the get the last step going. The last step, see http://xn--dahlstrm-t4a.net/svg/html/get-embedded-svg-document-script.html for an example (reaches into a referenced svg resource from the surrounding html to set the fill color). That shows how to grab the svg document (and consequently the contentWindow), so if you combine it with something like http://stackoverflow.com/questions/251420/invoking-javascript-in-iframe-from-parent-page then you should have all you need to be able to call functions inside the svg scripts. Alternately, is there anything in ECMAScript/SVG that allows persistence across sessions? You can store some data with HTML5 localStorage and/or sessionStorage. Both should be available on the window object, so should work even if svg is the main document.

This results in incorrect font-sizes in browsers. - Markers are not set to allow overflow, so they will be clipped by UA:s that support markers properly To fix: - Add 'px' to any unitless font-size value - Add overflow=visible to any marker element These problems may have been fixed in later versions, it would be nice if anyone here could confirm that.

Re: [svg-developers] Re: Animated path or polyline using SMIL keyTimes or similar
Yes, I think that should be possible. If you set the 'pathLength' attribute to some known value on the path element you want to trace, then you know how long the path will be in advance. Then you can calculate what to set the stroke-dashoffset to (eg. for 10% of the path it would be 10% of the 'pathLength' value). Then set stoke-dasharray to the 'pathLength' value. You can have a 'keyTimes' that corresponds to each value in the 'values' attribute, and make sure they have the same number of values otherwise it won't work. Another option if you don't want to use 'pathLength' is to query the UA for the pathlength, with pathelement.getTotalLength(). That requires scripting though.

Re: [svg-developers] Missing glyph substitution

Hello,
I have a text and an SVG font. From what I understood, if I define a
style with two fonts: my font and also with some other font, say:
.mystyle { font-family: myfont, otherfont }
what will happen is that the text will be set in myfont unless the
needed glyph wont be found in it, then otherfont will be used. Right?
In theory yes.
My question is, is it possible to automatically set all the glyphs
from otherfont in other color, say red?
For instance: myfont has ABC glyphs and otherfont has abc. So
the text:
span style=mystyleABCabc/span
will have the other half set in red otherfont.
In other words, is it possible to let the user know that the glyph
substitution occurred, possibly without javascript checking every
letter in the text whether it has corresponding glyph in first font or
the other?
In theory yes.
There are two problems:
a) the font-family matching may (and most probably will) switch to another font
other than the 'otherfont' in current viewers
b) to the best of my knowledge no viewer currently supports full svgfonts, only
the subset defined in SVG Tiny 1.2 (which allows you do define the glyphshapes
but not to style the glyphs in the font itself)
If you wanted to use one font and then another, you could do for example:
text font-family=myfontABCtspan font-family=otherfontabc/tspan/text
And if you wanted to have the uppercase abc in red, just add fill=red to that
element, and set another fill for the tspan.
Why do you need to know which font a particular glyph came from?
Cheers

Re: [svg-developers] Re: Report on SVG Viewer Performance
On Thu, 04 Dec 2008 07:12:30 +0100, Frank Bruder [EMAIL PROTECTED] wrote: Great work so far. Just three comments: ... - Your testing method does not necessarily measure a relevant benchmark. A scripting engine which queues events in such a way that interval and timeout events always are executed in the correct order would get perfect scores, no matter how much time the rendering takes. In the second call to setInterval() you could create a Date object each time and use that for measuring, to account for the possibility that the longer interval might be delayed in accordance with the shorter interval. Furthermore a user agent could switch to rendering only every other frame when the animation speed would otherwise slow down too much. Video player software commonly does this. I would agree that doing DOM modifications and checking how long it took before it could do the next update/modification isn't necessarily very accurate. If little or no rendering is done at all, then you'd probably get a very high score. There's no guarantee that the DOM modifications actually result in a new rendering before the next update call. This is what Frank is getting at about dropping frames, there's no guaranteed framerate. Second, the Date objects / timers that are used can have varying resolution/quality in browsers, and across platforms. That may skew results. Third, in any case why would you need a framerate higher than the screen refreshrate? For the DOM modifications sure, they should be expected to run as fast as possible. But unless you run with vertical sync disabled you'll not see the frames that are produced in excess of the screen's refreshrate, and if you do get the extra frames then you may well see tearing problems. So yes, it's good if the DOM modifications are as fast as possible, and yes it's good if the viewer can produce frames faster than it needs to actually draw them on screen, but I don't think that you're measuring actual rendering framerates. Another justified question would be: if you're not going to see the frames anyway, why should valuable CPU time be wasted rendering them? Anyway, you may want to check out the SVGSVGElement.currentFps[1] DOM API in the just released[2] Opera 10 for comparison. That property will provide the average framerate based on samples from when the svg was actually rendered to screen. And I want to add that performance testing is really important, and that the above points in no way invalidate your work. They're just things that may skew the results. What you see on your screen and in CPU and memory usage is what really counts IMHO, and it's clear that in that respect the SVG viewers keep improving at a steady rate.

Re: [svg-developers] getElementById-in-firefox-bug
Right, my hypothesis is: - since FF3 doesn't handle svg's animation (or SMIL if you will) elements they become unknown XML elements in the DOM - as a consequence the 'id' attribute isn't on an svg element that FF3 knows, and therefore is not thought to be of type ID = it's handled as any other unknown attribute Or in other words, what you wrote :) Cheers /Erik On Thu, 30 Oct 2008 16:54:19 +0100, Olaf Schnabel [EMAIL PROTECTED] wrote: Hi Klaus and Erik thanks for your answers.

Re: [svg-developers] progressive drawing of path -- attempt to use clipPath

Are you looking for a progressive drawing of a path geometry? If yes, you can do this by animating the stroke-dash of a path. Examples are provided: [1] and [2]. Yes; exactly what I was asking for. Pretty clever it is! Now I have a new question - consider the example at http://srufaculty.sru.edu/david.dailey/svg/unveilPath.svg (it uses SMIL so be sure to use a proper browser) I've simplified the basic example as much as I can, and am trying to animate the fill to follow the animation of the path. Clearly this is a kludge. However, what I did think of was the following: how about I stick a copy of the first half of the path (with its animated stroke-dash) inside a clipPath and then apply the clipPath to the original path. Then shouldn't the growth of the clipping region unveil the path as well as its fill, concurrently? Alas, it didn't work. From the spec [3] , we find that The raw geometry of each child element exclusive of rendering properties such as 'fill' http://www.w3.org/TR/SVG/painting.html#FillProperty , 'stroke' http://www.w3.org/TR/SVG/painting.html#StrokeProperty , 'stroke-width' http://www.w3.org/TR/SVG/painting.html#StrokeWidthProperty within a 'clipPath' conceptually defines a 1-bit mask (with the possible exception of anti-aliasing along the edge of the geometry) which represents the silhouette of the graphics associated with that element. A mask should be able to do the trick. Inside the mask just draw the path with white fill and/or stroke.

Do you know how to change the setting of opera for it to automatically offer the possibility of opening svg files or even all files? I don't think there's a pref setting for which file-extension filter is used by default, but I could be wrong.

No new svg features were added in 9.6. There was a fix made for XSLT that can affect svg, if an XSL stylesheet generated an ?xml-stylesheet? node that stylesheet was never applied to the generated output.

Re: [svg-developers] Composite filters with masks in Opera FF and IE -- standards and tests
On Mon, 13 Oct 2008 18:50:56 +0200, Dailey, David P. [EMAIL PROTECTED] wrote: ... http://srufaculty.sru.edu/david.dailey/svg/composite2.svg ... The chroma in FF and IE are more similar, but the radius in FF and Opera are more similar. In Opera the interaction between the chroma of the mask and those of the image itself seem to be more pronounced. Which implementation is correct? It's hard to say. I guess it would be possible to do a reference implementation based on the algorithms in the spec and compare the output bitwise. But since the actual rendering of shapes still leaves some wiggleroom you'd have to make sure that the filter in-data was bitwise exactly the same on all implementations, I guess using feFlood might work there. For the exact same indata and filter algorithm settings the implementations should produce the same output, at least in most cases. As we begin to talk about cross-browser standards for passing or not passing tests and benchmarks, I have been skeptical that specs will ever nail things down precisely enough to allow bitwise comparison of output. This little experiment ended up closer than I expected it would, but still supports the basic premise that exactness of output may never be pixel perfect across browsers. On the other hand, it seems as though the wild divergence of the case with the mask applied over the composite filter is a bit more divergent than I would have expected, and particularly when the animation is applied. Possibly due to anti-aliasing on masks being applied or not since that may give some edge noise if filtered. FWIW, the effect in Opera is what I was trying for, though I'm not confident that that's what it should have been. (Ultimately I wanted a fractal shape - not an oval - to be filled with fractal-looking chroma, wiggling cloud-like over time) This may be because of the way elements/effects are rendered, see[1]. If you had a mask that was defined by a shape that was filtered you might be able to get the effect I believe you want.

I noticed last night that Opera seems to have problem with missing nought characters in SMIL events (i.e. begin=.25s). Haven't done any thorough investigation though. I used to notice (a couple of years ago) that Opera had problems if I used dur=.5s instead of dur=0.5s, but thought that had all been fixed. Maybe I just got used to using 0. in my time units for SMIL. So yes, we'll need to make sure to include such cases. The syntax for the begin attribute is borrowed from SMIL, and the grammar doesn't allow for a . to start a Clock-value. Possibly this is because it can cause confusion with id-values, but I haven't looked at it in detail yet. Another somewhat related gotcha is dash/minus characters in id:s, that can clash with the event-value syntax, e.g. 'someid-0.4s.end' since 'someid-0.4s' is a valid id. What you need to do in such cases is to escape the dash in the id with a backslash. There are some boundary problems still existing of that type for example in http://srufaculty.sru.edu/david.dailey/svg/SVGOpen2008/filterBlur2.svg , if I put filter id=D x=0% y=0% width=100% height=100% feGaussianBlur stdDeviation=25,0 / /filter instead of filter id=D x=0% y=0% width=100% height=100% feGaussianBlur stdDeviation=25,0.1 / /filter (thanks to Erik for helping me figure this out) It should work, the spec wasn't explicit about this particular case though. If stdDeviation is 0 then nothing should be rendered according to the spec. However when it's 0 in one direction and 0 in the other then I agree it makes sense to render it. I'll see if I can clarify this in the SVG Filters 1.2 spec, and try to get this fixed in Opera.

SVG 1.2 Tiny allows this, see the spec[1] (and if you scroll down a bit from there, there's even a complete example of how to use it). In a solidColor element you can set the 'solid-color' attribute to whatever color you need using the normal svg syntax for colors, and by giving the solidColor element an id you can reference this as a paintserver, just like a gradient, e.g url(#mycolor). Actually, solidColor defines a paint server, which, strictly speaking, is not the same as a color keyword. You can reference a paint server in the fill and stroke properties of a shape element. But color keywords can also be used in a gradient as the stop-color of a stop element. This is a place where you need to specify a color and a paint server is not an allowed value. On another note, it's possible to use a gradient with just one color for the whole range as a substitute for solidColor. This wouldn't require an SVG 1.2 viewer. Thanks, I've raised this as an issue for a future SVG spec revision [1].

Opera 9.5 supports this, if you are looking for something to test in. In the GeoSym standard, when the various attributes of a feature are looked up and evaluated to select a final portrayal image, the color of that image is defined by a specific name; that name has to be used as is, or else somehow translated from GeoSym into something that SVG can understand. Further, the same color name will refer to one of two different RGB values, depending on whether the feature is being viewed under day or night conditions. It's possible to animate the solid-color attribute, does that solve your problem? My question, my understanding of the underpinnings of SVG being as weak as it is, can this color definition method be supported within SVG itself, or must the colors first be translated into RGB values externally and fed to SVG? Depends if the colors are defined in svg already or not, see the color syntax[2].

Also Opera has implemented a finished rendering event that may appear in a future spec (fingers crossed) and so this can help those interested in benchmarking and calibration of time-sensitive events like real-time data visualization. What's implemented currently (internal Opera builds only at this time) is not an event, but a DOM attribute on the SVGSVGElement interface called 'currentFps' that you can access to query the current framerate. Though yes, nothing is technically preventing us from dispatching something like a frame rendered event. However, how that would affect performance is also something we'd need to evaluate.

Re: [svg-developers] appendChild problem in Opera / ASV6
Hello Olaf,
It's always useful if such bugreports go directly to the Opera bugtracker
(as early as possible), http://bugs.opera.com/wizard.
I've logged this now as bug #345632.
Anyway, in theory you should be able to use something like this in your
example:
style type=text/css
rect:hover { stroke: red; }
/style
I think that's marginally cleaner than changing the stroke in script, but
of course that still doesn't solve the problem with elements that are
taken out of the tree.
Cheers
/Erik

But this is just a workaround, the problem still remains. Opera and the
Adobe Plugins (3 and 6prealpha) both lose the focus on an active element
if it is moved in the DOM. I think this is a bug.

http://www.ika.ethz.ch/schnabel/append.svg I have several rectangles.
In
a first step, the stroke of the active rectangle is set to red on
mouseover. Then, the active rectangle is set on top of all other
rectangles via appendChild. This works in all browsers but Opera 9.5 and
ASV6 seem to lose the focus on the active rectangle. Therefore, the
onmouseout event (set stroke to none) doesn't work anymore (except
Firefox 3, which seems to interpret the code correct for me).
Has anyone a workaround for this problem?
Thanks for your answers

The level of svg support varies among browsers, so to be able to do a fair comparison of performance you should first remove everything that isn't handled by some browser. See the menu roll overs for just one example. Also the zoom needs work. Current speed deficiency makes it unusable for SVG web presentations. Have you tried common content optimization strategies [1]? For example: - using 'display' is way better than using 'visibility' - are your the filter chains optimal? I.e. using only as many steps as required, and limiting the filter region using x,y,width,height on the filter element? - do animations run endlessly? I.e. even when not visible? When tested with Webkit: Good SMIL animation speed. Sure, remove the filters (which webkit ignores) and you can expect the same in Opera too. ... When tested with Firefox: What test? Has no support for SVG fonts, SMIL animation or filters. Filters are supported in FF3 (yaay :) I look forward to running this file perfectly in the near future. Well, it's a good stress-test for sure. Though your best bet for making it work in the current generation of browsers will involve making different design choices, for example not using SVGFonts, and perhaps using javascript for animations (though FakeSMILe is an option if you prefer to keep the declarative animations there and still have it work in FF and Safari).

Is that how you think it should work? I’d appreciate your input for Web IDL. It's clearly desirable to be able to add custom methods and data on any of the svg interfaces.

Hello Erik,
You're right!
with Opera :
evt.target: [object SVGElementInstance]evt.currentTarget: [object
SVGUseElement]
With FFX :
evt.target: [object SVGUseElement]evt.currentTarget: [object
SVGUseElement]
So, to deal with evt, i use now :
if (typeof evt.target.id != 'undefined') // don't find a better way
to check
{
objet=evt.target.getAttributeNS(null,id);
}
else {
objet=evt.currentTarget.getAttributeNS(null,id);
}
It seems you are not interested in the id:s of the use:d elements, only
the id:s of the use elements themselves. If that's true then you can use
evt.currentTarget everywhere and just remove the unnecessary specialcasing.
Now I can fill shapes with bitmaps patterns and compare patterns with
IE, FFX and Opera : ex-equo IE and Opera, FFX shows white line at
junction(varying when zooming).
Perhaps those are anti-aliasing or alignment issues? You can always play
with the 'image-rendering' and 'shape-rendering' properties to see if that
helps.
As i use svg like a simple scripting language, i find IMHO that it is
not consistent to have two different syntaxes to access to an object
(is it for secutity issues?). I see that i will have to deal with
that for groups ...
Oh? Is this not the same as the issue with SVGElementInstance? Feel free
to share some more details. :)

When i tested it with Opera, it doesn't work. At loading,I get The GetSVGDocument interface is not supported message, not with FFX. Embed with svg:s in Opera 9.2x may sometimes give a non-consistent result unfortunately, should work consistently in 9.5 though. Replacing embed with object usually helps. And now, trying my svg generated code working with FFX3b, with Opera I have a type mismatch error at objet = evt.target.getAttributeNS(null, id); (syntax recommanded in http://jwatt.org/svg/authoring/ i decided to follow ... and works well for FFX) that i can replace by (as i can see in the example code) objet_temp=evt.target; objet=objet_temp.id; FF doesn't implement the SVGElementInstance DOM, so my guess is that you are seeing this on elements that were use:d. Inspect the type of evt.target to see what it is, alert(evt.target: + evt.target + evt.currentTarget: + evt.currentTarget). Sometimes evt.currentTarget is what you wanted, sometimes it's not. For example there can be cases where you want to know which one (of several use:d instances) your event occurred in, and sometimes you only want to get at the real elements that the use pointed to. I hope that makes it easier to understand :) Anyway, both of your ways of getting id:s should work just fine, provided of course that you have an SVGElement or a Node, in case you have an SVGElementInstance then there is no id attribute since it's a shadow tree element. By reading the SVG 1.1 spec it's clear that SVGElementInstance has no getAttributeNS method on it - it doesn't implement the Node interface, only the EventTarget interface. For details see: http://www.w3.org/TR/SVG11/struct.html#InterfaceSVGElementInstance (definition of the SVGElementInstance interface) http://www.w3.org/TR/DOM-Level-2-Events/events.html#Events-EventTarget (definition of the EventTarget interface) but somewhere in my code, i have to use getAttributeNS to parametrize the attribute's name to factorize my code ... so thanks to avoid me to go deeper in that bad way ... I have to work more to be compliant with Opera ... So it is late now I agree that it's unfortunate that Firefox implements use incorrectly, since it hurts interoperability, but perhaps this can be fixed in time for the FF3.0 final version? That SVGElementInstance isn't implemented is one thing, that FF by cloning nodes instead of conceptually cloning nodes also has side-effects such as the fact that CSS selectors applies to the shadow trees (which the spec tells you they must not). The SVG 1.1 testsuite didn't have any tests covering these cases though, but such tests will no doubt be added for future releases.

I suppose the above should be:

onzoom, 'alert(test);');
But I find it's usually better to use addEventListener instead:
document.getElementsByTagName('svg').item(0).addEventListener(SVGZoom,
function() { alert(test); }, false);
Additionally some implementations may not find the element until the
document has loaded fully, so you might want to setup the listener from an
onload handler to be sure.
Hope this helps

What you can do is test for the availability of said method, and fallback to something else if it's not there. Does anyone knows how it is possible to implement this method in SVG 1.1 and ecma-script? Stefan See here: http://the.fuchsia-design.com/2006/12/getting-svg-elementss-full-bounding-box.html If you want that to work in ASV (which lacks the getScreenCTM method AFAIK) you need to implement that in javascript as well. I'm sure someone on this list can point to such a workaround, but the above code works fine in all svg browsers that implement getScreenCTM (e.g. Opera, Firefox, Batik and probably Safari).

Re: [svg-developers] Re: Wavy line symbol in SVG
Hi Andreas, Nothing wrong with your example, but the effect is quite subtle on your font, a larger amplitude will show you that the glyphs are indeed stretched. However, I think this will still not give a satisfying result by itself, but it depends on the curve. Another way, which may be a bit of a pain arguably, is to do placement using script, creating custom shapes rotated to follow the line. The SVGMatrix DOM methods and SVGPathElement methods 'getPointAtLength' and 'getPathSegAtLength' might help a bit. If you want the rotations you can go the textPath route again, see the SVGTextContentElement method 'getRotationOfChar', but note that you need to know the font advances beforehand, for example by creating a small svgfont.

Changing target to currentTarget makes it work in Opera, Batik and Firefox. quote href=http://www.w3.org/TR/SVG11/struct.html#UseElement; The event handling for the non-exposed tree works as if the referenced element had been textually included as a deeply cloned child of the 'use' element, except that events are dispatched to the SVGElementInstance objects. The event's target and currentTarget attributes are set to the SVGElementInstance that corresponds to the target and current target elements in the referenced subtree. An event propagates through the exposed and non-exposed portions of the tree in the same manner as it would in the regular document tree: first going from the root element to the 'use' element and then through non-exposed tree elements in the capture phase, followed by the target phase at the target of the event, then bubbling back through non-exposed tree to the use element and then back through regular tree to the root element in bubbling phase. An element and all its corresponding SVGElementInstance objects share an event listener list. The currentTarget attribute of the event can be used to determine through which object an event listener was invoked. /quote So, reading DOM 2 Events [1] and applying the above the conclusions I reach are: - The evt.target is the SVGElementInstance that was clicked (the shadow element of a rect in the example). This stays the same as the event bubbles up the tree. - evt.currentTarget changes as the event bubbles, and is set to the EventTarget that is currently handling the event during the event capturing/bubble phases - Making the use element be the evt.target by user interaction is not possible AFAIK, but could be done if creating and dispatching the event with DOM methods. - For use elements it's always good to use evt.currentTarget in eventlisteners on the use element If these conclusions are correct then both Batik and Firefox have a bug in that they don't return an SVGElementInstance as the evt.target. In Firefox' case I suspect it's simply that the SVGElementInstance DOM has not been implemented yet [2][3]. Not sure about Batik, but it could be the same there.

Re: [svg-developers] How to load a SVG as String into a SVGDocument

As I see there is no DOM function loadXML(String) in SVG. So if you
have a String with the complete SVG code, how can you transform it
into a SVG document?
There are a few ways to do that:
- Using the parseXML method [1] in SVGT12 (if that's supported by the
viewer).
That can be tested in script like this: if(!parseXML) { /* no parsexml
*/ } else { /* has parsexml */ }
Also note that ASV supports parseXML but that it's slightly different
from the SVGT12 definition of it.
There are a few wrappers scripts that make it easier to use this on
existing viewers, see for example kevlindev[7], or the end of the svg
video article here[5].
- Using DOM 3 Load and Save [2], example:
var lsinput = document.implementation.createLSInput();
lsinput.stringData = hey parse this!;
var lsparser =
document.implementation.createLSParser(DOMImplementationLS.MODE_SYNCHRONOUS,
null);
var document = lsparser.parse(lsinput);
- Using XMLHttpRequest [3], see carto.net[4] for a good reference of how
to use that.
- Using DOMParser, see examples here[6].

The data plot looks awful because of coordinate transformations. The problem is that the test duration is 0.005 seconds (x-axis of the graph) and the y axis is +-10 volts. It is important to me that the svg files are complete records of the test and that they can be opened in ASCII and have the actual data presented. Right now I can apply my own scales to the data before putting it into a path element, but that does not preserve the raw data. For example, if I multiply all of my raw x-data by 16, my data range is now 0 to 800. I have done this and I get a nice looking 800x600 plot (sy=-30,ty=300), but I want a nice looking 800x600 plot with raw data in the svg file. If you are willing to give up the everything must be in one file-requirement you could keep data as XML and use XSLT to transform it into svg. I've tried g transform='matrix(sx 0 0 sy tx ty)', but my x-scale is so huge (160,000) that when I draw a line with stroke-width=1 it is very ugly. I also can not write legible text under that transformation for my grid line labels. Is there a way in SVG to specify a new coordinate system without applying transformations to the strokes/text width? There is a thing called vector-effects in SVG Tiny 1.2, see http://www.w3.org/TR/SVGMobile12/painting.html#NonScalingStroke. I have also tried an svg width='800' height='600' preserveAspectRatio='none' viewBox='0 0 0.005 20' gpath ... //g /svg. In summary, I think I want a new coordinate system for the locations (x, y) but not the dimensions (height, width). If you want two different coordinate systems why not use nested svg elements, or a symbol+use. That way you can scale your data set independently from the text labels.

My windows Opera 9.5 build 9735 didn't show any errors in the console for
the above example, except for the missing scaleLegend function, same for
Opera 9.24.
May I ask what version of Opera (with build number and platform) you see

Just to make sure, this is what I'm testing (I wrapped your example in an
svg tag, and open the file locally):

onclick=changeColour('Purple',true) height=17
width=17 transform=translate(53 181) scale(1) id=purpleRect
stroke-width=1.6/
rect onmouseover=scaleLegend(evt,1.1)
onmouseout=scaleLegend(evt,1) stroke=none fill=#25FF28
onclick=changeColour('Green',true) height=17 width=17
transform=translate(79,181) id=greenRect stroke-width=1.6/

onclick=changeColour('Grey',true) height=17 width=17
transform=translate(131,181) id=greyRect stroke-width=1.6/
/a
/svg
My error console only shows warnings about the scaleLegend function not
existing in this document, tested in Windows opera 9.23 build 8808.
Even the simplified example below didn't show any warnings at all in the
console:
svg xmlns=http://www.w3.org/2000/svg;
xmlns:xlink=http://www.w3.org/1999/xlink;
a xlink:title= cursor=pointer
/a
/svg
According to the spec an empty xlink:title attribute is perfectly valid,
even though I would say it's sad that the workaround with an a element
is needed since you don't actually need or want a link it seems.

Re: [svg-developers] low resolution on firefox (2.x) svg native player

I noticed that the svg native player of firefox (2.x for windows) has a low resolution than firefox (2.x for linux) and IE. The difference is similar to low and high resolution of adobe svg plug-in (ver. 3.x). Anu suggests? After having looked at the source, two things: - ASV3 doesn't seem to support preserveAspectRatio=xMinYMin meet and instead seems to use preserveAspectRatio=none. - The text looked different indeed, but that's ok according to the svg spec. If you want it to look more similar you can add text-rendering=optimizeLegibility to get ASV to render the text so that it's less fuzzy. The spec however doesn't guarantee that you'll get the same exact appearance, even if in practice that's usually what you get. Also you should probably specify a font-family if you want some particular font, otherwise it increases the likelyhood that it will look different in different viewers. Opera rendered the example just fine, as did Firefox and Batik. About resolution differences, it may be that a different interpolation algorithm is used when drawing the image. You can try the various values for the 'image-rendering' property, such as 'optimizeSpeed' or 'optimizeQuality' and see if that gets you the appearance you want.

Well, just open the error console (Tools Advanced Error console) and see the error messages. You have a bunch of elements which are not found because of incorrect id:s for example.

See: http://www.carto.net/papers/ svg/textFlow/ and http://www.carto.net/papers/svg/textFlow/index.svg as an example. Multiline editable text can be done with SVG 1.2, but I don't think any of the available web-browsers implement this (maybe an early preview of Opera, if at all). Opera 9.5 introduces support for the multi-line textArea element in SVG 1.2 Tiny, and also editable text. Still in beta, which means please report any bugs you find with that. Here's a short example: textArea editable=simple height=100hello world/textArea Single-line editable text: text editable=simplehello world/text Alternatively you can use HTML widgets with SVG if you need multiline editable text. Yes, that makes it work better across browsers.

Hi,
I wrote a simple SVG countdown. You can read it above. It is okay from
5s to 0s, but the higher I start, the longer the code is...
Is there a way, in SVG, to do that much more shorter than defining a
text element for each number ?
Thanks.
Rémi
If you are willing to use scripting, you can just update the value of a
single text element every second instead of displaying multiple text
elements in succession.
I did that first but the time in javascript doesn't seem to be exactly
the same than the one in the SVG document (rendering engine of Opera).
Right, there is nothing that says that those should be synchronized, so
you shouldn't count on that.
However, it's possible to trigger scripts based on animation events like
this if you want to be in sync:
svg xmlns=http://www.w3.org/2000/svg;
xmlns:xlink=http://www.w3.org/1999/xlink; viewBox=0 0 600 600
script
var i = 0;
var texts = new Array(text 2, text 3, text 4, text 5);
/script
defs
animate id=dummy attributeName=fill to=black dur=1s
repeatCount=5
onrepeat=document.getElementById('text').firstChild.data=texts[i++];/
/defs
text id=text style=text-anchor:middle; font-size: 30px; fill: black
x=50% y=50%text 1/text
/svg
Works in Batik 1.7, Opera 9.x, ASV3.
In my case, I had, next to the countdown from 5s to 0s, a rectangle whose
width was moving from 0 to 100 within 5s. Here is the code :
rect x=0 y=100 width=10 height=20 stroke=black fill=red
animate attributeName='width' begin='0s' dur='5s' from='0' to='500'
fill=freeze/
/rect
and 5 s in javascript are not 5s in SVG document... When the rectangle
freezed, the javacsript countdown wasn't at 0.
It is the reason why I was wondering if there were a possibility in SVG
to have a kind of repetition of an animation with an incrementation.
Well, you can use accumulate=sum to add to have an animation add to the
previous value as it repeats, but it only addresses the cases where
attributes are additive. See
http://www.w3.org/TR/SVG11/animate.html#AdditionAttributes for more
information, there are a few examples there.
Cheers

Hi Nico,
What a fun problem!
I fiddled around with it just enough to confirm what seems like odd
behavior in the browsers:
The enclosed code (with a simple .js file of some sort added on ) shows
very different behavior in Opera 9.5alpha, FF1.5 and IE
with FF able to run the code from the script built through DOM. FF
behaves the way I would expect it to.
Ok, that is contrary to my experiments :)
See below for source of that.
I am not sure where within DOM one would expect the text of a .js (or
.es) file to actually appear, which is why I was experimenting with
various DOM explorations here. If the commented out code (both SVG and
JavaScript) is commented back in then all three browsers see three
script tags, but only in the first case, when the code is provided
in-line, can I figure out how to interrogate the source code
programmatically. Only in FF is the script, thusly constructed,
executable.
This is another problem, no? You're looking for a way of getting the text
content of a script element that has external content?
Since FF works the way I expect it should, it is probably the one which
is buggy. Erik Dahlstrom has pointed out that some of the CDATA hoopla
that I typically use is more extravagant than it needs to be, so in this
context my extraneous hoopla could prove problematic since it does pop

why or when one would do that.

Replacing the line above with:
alert(SCR.item(1).getAttributeNS(xlinkNS, xlink:href))
gives me the correct xlink:href back in Opera as well.
The question is whether this is correct in Firefox or not, is the name
given to getAttribute a localName or a qualifiedName? The DOM specs are
not very clear about that subject. And the same thing goes for
setAttribute. Now logged as bug 300509 in Opera's bugtracker.

I think you'll run into less problems if your viewBox is made a bit bigger.
'text x==-81.9332 ' obviously should be 'text x=-81.9332' if you
want it to work.
'script language=text/ecmascript' should be 'script
type=text/ecmascript'.
You should add 'xmlns=http://www.w3.org/2000/svg;' on the svg root
element.
===
//*commonMap.css
file***
*.FreewayText
{
text-anchor: middle;
font-family:Verdana;
font-size: 0.001;
color: black;
}
//***end of css file
You must specify font-size using a unit, otherwise it will be ignored,
0.001px will do.
Here is my take on your files, which works fine in Opera 9 and Firefox 2:
//*svg file***
?xml version=1.0 standalone=no?
?xml-stylesheet href=commonMap.css type=text/css?
svg id=mainMap

{
var style = getComputedStyle(document.getElementById(t),null);
alert(style.getPropertyValue(font-size));

Re: [svg-developers] svg clock for mobile
On Tue, 23 Oct 2007 23:47:59 +0200, ddailey [EMAIL PROTECTED] wrote: Hmmm... Thomas in Opera the current time for your link shows just fine (though it starts at midnight in IE). A similar thing http://srufaculty.sru.edu/david.dailey/svg/clock.svg also using SMIL seems to show current time in both IE and Opera. In looking at your code, I believe this is why: you use JavaScript to reset the rotation of each of the clock hands: var h_hrs = owner.getElementById(hourHand); h_hrs.setAttributeNS(null, transform, rotate(+ (30*hrs+0.5*min) +,105,105)); You should note that !-- isn't really a comment in the script, see e.g. http://lachy.id.au/log/2005/05/script-comments. Since you have specified additive=sum on the hourHand animateTransform element that means that the animateTransform transform will get postmultiplied on the hourHand transform. Then since the comment in the script wasn't really treated as a comment it will set the time also. So a simple fix is: make the comment in the script a real comment, by using /* ... */ or // ... Either way worked fine for me, that is either using setCurrentTime or setting the transforms. If you do both however, then you get both. Also it won't work in IE/ASV because type=text/ecmaScript has an uppercase S. Replacing that with text/ecmascript makes the script run fine. The problem (I suspect), at least in IE and possibly Nokia, is that the animateTransform that you've attached to the objects uses its own default rotation angles (specified through markup) to override any attributes associated with the rotation itself. That is the transform=rotate(string)is being clobbered by the animation itself. Why Opera wouldn't do that, Idon't know, but that browser has the sometimes uncanny ability to figureout what we are trying to accomplish. According to the SVG spec[1] the transform on the target element shouldn't get overwritten when additive=sum is used in an animateTransform, but you can use additive=replace to get that effect if you want. I think both ASV and Opera behaves this way, at least the simple examples in the spec looked the same when I tried them.

9.23 it doesn't appear to do the onload. Am I misinterpreting how

It worked fine if I switched the setAttribute(onload) bit for this:
img1.addEventListener(load, function() { alert('bar'); }, false);
FF2 behaves the same as Opera here, and Safari 3.0.2 strangely reported
more than a few load events.
Not sure if there should be a difference between setting onload and
registering an eventlistener, will follow up on that.

Re: [svg-developers] Text flow and word wrapping

Opera 9.5 introduces support for textArea, from SVG Tiny 1.2. This allows textflow in a rectangular region in SVG. Another option to use foreignObject to let HTML do textwrapping for you, in case more advanced layout is required (images, lists etc). The working draft from 2002, says this: Text 1. SVG 1.2 should allow word wrapping and forced line breaks for text within multiple rectangles [SVG 1.2] 2. SVG 2.0 should allow word wrapping, forced line breaks and text flow within multiple shapes [SVG 2.0] 3. SVG text should allow justification locations, such as the nine standard positions (bottom, center, top with left, middle, right). Note that this requirement will involve coordination with the CSS and XSL groups, and investigation by the Internationalization group. [SVG 1.2] [SVG 2.0] 4. SVG may allow text to be justified flush within a shape. [SVG 2.0] 5. The transform attribute should be added to the tspan element [SVG 1.2] 6. SVG should provide a method to define how whitespace is handled. SVG may provide an attribute that defines how a text element should handle whitespace, overriding the use of the xml:space attribute. [SVG 2.0] Is there anything which is more recent that could fill me in on where things have gone since then and where they are going? I haven't been able to find anything on line. If you're looking at something to happen short-term then SVG Tiny 1.2 is the best bet, it can already do some of the things in the list above. SVG 1.2 Full might be some time away still. I am interested because of a long term project of my mine using a variety of different languages and different scripts to present fairly long text documents - that is from 1000 to 5000 words - which need to use embeded SVG fonts - it is something I would like to be able to begin making available within the next year. Looking at what's happening, it's possible that downloadable fonts will be in browsers before SVG 1.2 Full is available, and those downloadable fonts should be possible to use both in HTML and SVG. I think webkit is the first to offer this functionality, see http://webkit.org/blog/124/downloadable-fonts/. For presenting long texts I would probably go with HTML anyway.

Re: [svg-developers] Simulating non-rectangular tilings with pattern

Odd and even numbered triangles are filled with different gradients (mainly since if the fy attribute of the gradient is not tweaked then the center of the gradient defaults to the center of the bounding rectangle which is rather different than the perceptual center of the triangle).* I sought to try simplifying things by building the tiling it with pattern rather script. I think any periodic tiling of the plance can be simulated with a rectangular pattern. To simulate the two adjacent equilateral triangles, I split one of them into two halves -- both right triangles -- and appended these halves on either side of the whole one. The pseudo-triangles tile just fine, as can be seen at http://srufaculty.sru.edu/david.dailey/svg/triangles5.svg ** The problem is that I can find no way to fill the adjacent half-triangles with what would appear to be a shared radial gradient -- even by adjusting the horizontal offset fx of the gradients of each. If they share the same radial gradient, then that gradient appears centered relative to the bounding box of each half-triangle individually. You could perhaps try to make the half-triangles into full triangles, but let half of the triangle fall outside of the viewbox of the pattern. That way the fill will look the same as for a full triangle, and hopefull pair up with the next tile. What I want to do is to create something identical to http://srufaculty.sru.edu/david.dailey/svg/triangles4.svg but with pattern instead of DOM. My thought is that it oughta be faster -- but who knows? maybe it won't be. Any insights on the relative speeds of such things? My guess is that if you have a large area to tile on then using patterns will be faster than having the same thing drawn a number of times. If you're not tiling a large area then sometimes it's faster to draw the same thing repeatedly (like in your scripted version).

Well, you have all of the methods and properties available on the SVGElementInstance interface[1] at your disposal. And you could use evt.currentTarget if that's what you want.

If you hide something that is costly to render then yes. will it be faster for the svg file to 'react'? why is this? By using display=none you're telling the user agent that this particular subtree doesn't need to be considered for e.g mouse events, and that the user agent can skip the subtree when rendering. If using visibility=hidden the user agent still needs to process the subtree because any child element can override visibility, and this is not the case with display.

Re: [svg-developers] Re: Carousel Animation - any way declaratively?
On Tue, 25 Sep 2007 05:17:49 +0200, Jeff Schiller [EMAIL PROTECTED] wrote: David, Painter's Model: http://www.w3.org/TR/SVG11/render.html#PaintersModel I'm not sure, but I think you missed the key aspect here - think of the icons on a carousel that we're looking at on a horizontal elevation. This problem has to do with rendering order more than highlight and event handlers (though that is another interesting topic). Let's say you have 3 icons on the carousel - as it spins, icon 1 (which is to the left of center) and icon 3 (which is to the right) are behind icon 2 (which is in front and center). As the carousel spins clockwise, icon 3 moves to the center and in front (i.e. on top) of the others, while icon 2 is now to the left of center and behind icon 3. Do you see what I mean by z-order? Because the rendering order and overlapping is defined by the order in which the elements appear in the DOM, it seems that you couldn't declaratively do the animation (you'd have to have script to rearrange the nodes as the icons rotate - probably using two halves of the carousel circle as separate rendering groups with nodes being popped and pushed appropriately). Jeff, Have you tried a solution that uses use elements for keeping the z-order the way you want it? Simple example: rect id=a set attributeName=xlink:href to=#a begin=mouseover xlink:href=#top/ /rect rect id=b set attributeName=xlink:href to=#b begin=mouseover xlink:href=#top/ /rect rect id=c set attributeName=xlink:href to=#c begin=mouseover xlink:href=#top/ /rect use id=top xlink:href=#a/ I have been trying to find good solutions to the z-order problem as well, moving elements around in the tree and expecting mouse events to cooperate is quite hard in my experience. That is, if I want something to move to front when I mouseover it, the only way I've found reliable is to use scripting, because the instant I move an element to the top I get another mouse event on whatever was under it (because moving it means take it out of the tree, then inserting it somewhere else), and that makes the element that I wanted to have focus lose it. So, I have to block events until everything is in place.

A fix for this bug will probably be in the next Opera 9.5 release. If you want it to work in ASV and older Opera releases I suggest you try to work around this bug. It could be depending on the fact that 'use' creates a shadowtree structure, which may be handled differently in different viewers. One workaround it is to clone nodes using script, since at least in Opera's case the bug is triggered by having an 'a' element inside of a shadowtree.

FF and Opera don't like font-sizes in CSS 'style' without the unit specified. That's half of the reason why your font's look huge, the second part of the reason is that your viewBox is small which makes the default fontsize that Opera/FF uses look big. I suggest that you specify the unit, such as style=font-size:0.4px in all places where it's missing. ... The comic contents page has some small SVG's on it and links to main parts. If you follow the recomended path for new users you get some stuff about how to view SVG files and the scenario of the comic before getting into an actual SVG comic. The first one instructs you on the interactivity and doesn't have much plot. Then you get a title page which can take a while to download and crashes Opera. Opera is very busy trying to do the background filter. You may consider cutting back on the complexity of those filters :) Limiting 'numOctaves' on your feTurbulence filter primitives should help a bit, a value such as 80 is unlikely to make much visual difference from say 3 or 4? Even ASV takes a long time to render the first svg because of that background. I'm guessing that you're using filters for the backgrounds all over, so in general trying to limit the complexity will probably improve the viewer experience.

Re: [svg-developers] Detecting when rendering is complete

wrote:
I believe I have seen this question asked and answered here before, I
may even have asked it (though I sincerely doubt that I ever answered
it).
So apologies in advance for retracing any overly familiar ground.
Is there some way to tell when a complex page has actually finished
drawing?
Apart from looking at the user agent, no. You may get an indication based
on the level of CPU usage, or other such metrics, but nothing exact.
There's no event sent when rendering is finished, because defining what
that means is probably not so easy. The same problem I guess can be Can
you tell when a complex HTML page has actually finished drawing?.
I am trying to do some timing to see how much time various things take
in the SVG DOM. If I add, for example, 3000 text nodes
using code like:
try{suspendHandle = Root.suspendRedraw(1);}
catch(e){}
D0=(new Date()).valueOf()
for (i=0;i3000;i++)addNode(text)
try{Root.unsuspendRedraw(suspendHandle);}
catch(e){}
D1=new Date().valueOf()
display(D1)
I find that the second date object D1 is calculated and displayed before
the text actually finishes drawing on the screen.
That's the expected behaviour. unsuspendRedraw just tells the UA that it
may draw the image again, not that it has to do it right away. There's a
forceRedraw method that can be used, but the 1.1 spec isn't that clear
about if that does anything if suspendRedraw was called first. It probably
should force a redraw though.
And if forceRedraw is not implemented as a synchronous operation then you
are screwed anyway.
Is there another event that fires when all the rendering is complete?
No, and also note that it may be difficult to say when it's complete. Some
scripts constantly modify the document. There's no way to say it's done
in such cases.
Hope I didn't discourage you too much. suspend/unsuspendRedraw are meant
as ways to optimize the content because the user agent can skip doing
unnecessary partial redraws. I don't think it was designed to help much
with doing performance measurements/benchmarking.
One way to get some measurements would be to add an element that requires
user interaction. Then as you unsuspendRedraw, take one timevalue, and
when all drawing is complete you can probably count on that this last
element is clickable, so require the user to click it and take another
timevalue. The difference between those should be a sample of the
rendering time. Repeat and make an average.

This won't work for a couple of reasons:

only available on HTMLDocument objects.
b) SCRIPT is not an SVG element, since XML is case-sensitive, should
be script
c) There is no src attribute on script elements in svg, you should use
xlink:href instead
So, instead try:
var script = document.createElementNS(http://www.w3.org/2000/svg;,
script);
script.setAttributeNS(http://www.w3.org/1999/xlink;, xlink:href, url);
svgRoot.appendChild(script);

Re: [svg-developers] Optimal SVG transformations

Hello,
I've been playing around with svg transformations and would like to
know if you have any recommendations.
I have the need to stack several transformations on top of each other
and I've tried benchmarking SVGMatrix against my own javascript matrix
class by running a loop several thousand times like this:
for (i=0;imaxIterations;i++){
tmp = Math.random();
matrix.scale(tmp*10).skewX(tmp*11).rotate(tmp*12).skewY(tmp*13);
}
For maxIterations 5000 to 6000 SVGMatrix is faster than my
javascript matrix class but above the javascript version pulls ahead.
Well, if you create your own custom javascript objects they would also be
garbagecollected at some point.
I guess it's because the SVGMatrix methods returns a new matrix when
called (and therefore triggers the carbage-collector) while my methods
alters the current matrix. So I assume that in a somewhat normal
use-case using SVGMatrix should be the best option?
I would recommend that yes.
Another question I have is regarding the best way to assign a svg
element a new SVGMatrix.
Is something like:
var e = document.getElementById('erect1');
e.transform.baseVal.initialize(svg.createSVGTransformFromMatrix(matrix));
Or perhaps:
e.transform.baseVal.setMatrix(matrix);
faster than?:
var e = document.getElementById('erect1');
e.setAttributeNS(null,transformation,toStringSVGMatrix(matrix));
I would guess not, and if you're doing this in a loop many times then your
first option would probably be faster. And I predict that setMatrix is
faster than both of them.
(where toStringSVGMatrix is a function that formats the matrix into a
string)
I would like to avoid the first one as I find it ugly…
I agree, that isn't the best way to do what you want, setMatrix should be
better.
I've also noticed that SVGMatrix is absent from SVG Tiny 1.2. Is doing
it yourself in javascript the only option when using SVGT 1.2?
It's not absent, see
http://www.w3.org/TR/SVGMobile12/svgudom.html#svg__SVGMatrix.
The methods available on SVGMatrix are slightly different, except for
inverse(), the mTranslate/mRotate/etc are the mutable counterparts of the
svg 1.1 methods.
Hope this helps

Re: [svg-developers] Patterns
Have you tried using fill=currentColor inside the pattern? Then you
should be able to set the 'color'-attribute on the element that references
the pattern and have it used in the pattern.
Hope this helps

Brendan asks about dynamically changing the content of a pattern.
defs
pattern id=checkerPattern patternUnits=userSpaceOnUse
x=0 y=0 width=20 height=20
viewBox=0 0 15 15
rect x=0 y=0 width=10 height=5 fill=blue/
rect x=5 y=5 width=15 height=5 fill=blue/
/pattern
/defs
I thought I had an example around somewhere but didn't find it easily...
Yes, what you wish to do can be done.
I'd do something like
changePattern(checkerPattern,newPatternGroup)
where:
function changepattern(id,newgroupid){
var P=document.getElementById(id)
for (i in P.childnodes){
P.removeChild(P.items(i))
}
//above should clean out the existing stuff in the pattern
//then add the new stuff
var G=document.getElementById(newgroupid)
P.appendChild(G)
}
where newPatternGroup would be a group (probably defined in defs)
containing the elements of the new pattern.
I think that oughta work in browsers that support pattern
hope this helps

SVGDocument.documentElement or SVGDocument.rootElement will get you the

You can see some nice svg examples covering this case and others here:

I like object more than embed since it has more predictible results. You are less likely to run into trouble if you use object in FF/Opera, with the drawback that it might not work in IE/ASV. ... a) image src=doc.svg is likely not ever to support scripting, even once individual browsers come to support that file type.

The link I mentioned earlier http://wiki.svg.org/Inline_SVG seems as consise and accurate as on this subject as any, though I seem to recall that Andreas Neumann had some pretty extensive stuff on this at his wonderful http://www.carto.net/papers/svg/samples/ site -- I can't seem to locate it quickly though. I agree it's convinient, let's hope to see more content like that in the future. c) there is a foreignObject tag in SVG1.1 (see http://www.w3.org/TR/SVG/extend.html#ForeignObjectElement) . It appears to have the purpose of allowing the embedding of XHTML (and other XML content) directly into SVG, I suppose somewhat like Microsoft XML data islands in HTML. I haven't seen any working demos of it, and the example code in the W3C specs is something I've not been able to make work in any browser (I'm hoping somebody can set me straight here.) I recently tried a FF3.0 nightly that had some support for foreignObject. Opera 9 has some support, but it's limited to external content (via xlink:href) at the moment. Here's an example that works in Opera 9: svg xmlns=http://www.w3.org/2000/svg; xmlns:xlink=http://www.w3.org/1999/xlink; id=svg-root width=800 height=600 foreignObject id=foo width=800 height=600 xlink:href=http://www.opera.com// defs linearGradient id=gradient stop stop-color=yellow offset=0/ stop stop-color=red offset=1/ /linearGradient /defs text fill=url(#gradient) fill-opacity=0.5 transform=rotate(-45 700 100) font-size=100 pointer-events=none font-family=sans-serifSVG on top/text /svg And here's an example that works in FF3.0: svg xmlns=http://www.w3.org/2000/svg; xmlns:xlink=http://www.w3.org/1999/xlink; id=svg-root width=800 height=600 foreignObject width=800 height=600 html xmlns=http://www.w3.org/1999/xhtml; body bgcolor=beige style=font-size:48px pThis is XHTML/p pClick to a href=http://www.mozilla.org/;visit Mozilla.org/a/p pThis is XHTML/p pThis is XHTML/p pThis is XHTML/p /body /html /foreignObject defs linearGradient id=gradient stop stop-color=yellow offset=0/ stop stop-color=red offset=1/ /linearGradient /defs text fill=url(#gradient) fill-opacity=0.5 transform=rotate(-45 700 100) font-size=100 pointer-events=none font-family=sans-serifSVG on top/text /svg I hope the foreignObject support in all browsers improves so that it becomes possible to use in the future.

Re: [svg-developers] Importing SVG from another file with XMLHttpRequest

First, as I'm new to this board: Hello everyone!
I'm having trouble importing external SVG with XMLHttpRequest.
It's inserted in the document but isn't visible. If I look at the
html-tab in Firebug the new element is there there but it's slightly
faded out. And when I inspect the DOM-ode of the element the
namespaceURI is null. I've tried using importNode but i doesn't help.
The code looks like this:
response = req.responseXML.documentElement;
importedNode = document.importNode(response, true);
tempElement = document.getElementById(itemID + Tank);
tempElement.appendChild(importedNode);
The elements is sent over with a very basic php-file:
?php
header('Content-Type: image/svg+xml');
echo(g id='fish' rect x='40' y='50' width='140' height='100'
fill='red' //g);
?
Remember that you're getting XML elements back unless otherwise specified.
You can try adding the svg namespace like this:
?php
header('Content-Type: image/svg+xml');
echo(g xmlns=http://www.w3.org/2000/svg; id='fish' rect x='40' y='50'
width='140' height='100'
fill='red' //g);
?
Then your elements should become SVG elements.
Hope this helps

Re: [svg-developers] Swapping attribute values on large numbers of elements
On Wed, 24 Jan 2007 06:58:29 +0100, simonshutter [EMAIL PROTECTED] wrote: Hi, I have a scenario where I need to plot hundreds of rectangles and each rectangle has two possible y values but all other attributes are static. To save space I was hoping to add two attributes that could be swapped in response to events. Does this make sense and what do you suggest as a method for swapping the two y attribute values? Would I have to loop over each element sequentially or is there a faster way? One alternative is to not specify a 'y'-attribute at all (defaults to 0), and instead group the elements in a g element. Then you give the g element a 'transform'-attribute to translate all the child elements to whatever y-value you want. The benefit is that you then change one attribute instead of hundreds, but depending on how your svg looks it may or may not be possible to group the elements in this way.
