Re: [svg-developers] Re: Roman numerals in SVG
The origins of the lines as a typographic trick probably bear some shared history with the use of underlining book titles as an authorial hint to the typesetter that the text should be italicized, though two generations of English teachers have since taught students to underline book titles, even though they were supposed to be italicized. In my case, though, I really did need the overlineunderline option: http://cs.sru.edu/~ddailey/svg/2011/simplePuns.svg [1] This doesn't work in FF or Opera, but it does in ASV. cheers David On Sun 10/16/11 12:35 PM , Kenneth N nelli...@gmail.com sent: Works in Mac Safari 5.1 as well, but I don't believe that that is the proper way to present Roman Numerals. Just display them as upper case in a serif font. I remember back in grade school our teacher would write out the upper-case letters of the Roman numerals and then draw the two lines across them all, but I think this was just a short cut to drawing serifs on all the letters. Frankly, I don't think even the serifs are necessary if context makes it clear that Roman numerals are being presented. âKen --- In , Cameron McCormack wrote: Hi David, On 15/10/11 1:34 PM, David Dailey wrote: I assumed I would just apply text-decoration=overline, underline or two instances of text-decoration, one with overline and one with underline to make Roman numerals, but this appears not to be the case.

The jerkiness you see is due to selecting different font-sizes, it's not a SMIL issue. You'd get a smoother animation if the same glyph outlines were used all the time. Thanks Erik, but that doesn't explain why it has no jerkiness in Safari, and the code doesn't actually referto font-size in the animation. Maybe I wasn't clear enough: any transform may affect the size of the text on screen. Now, the browser knows this, but there are (at least) two ways you can select the glyph outlines - before or after the transforms have been applied, so in one case you extract glyph outlines at size 14px and then scale those, and in the other case if you had a scale(2) transform you might extract the outlines at actual fontsize 28px. Subpixel fontsizes combined with this can lead to a sort of staircase effect, as seen in some browsers. This was mentioned in the talk by Google Docs at SVG Open the other day, http://svgopen.org/2011/registration.php?section=abstracts_and_proceedings#paper_52. The solution that was proposed was to use text-rendering=geometricPrecision to mean that you want the smoothly scaled transition. However, this doesn't yet solve the problem since that fix has not yet been made in all the different browsers. Note that geometricPrecision can lead to text that is harder to read, and the spec says that by default more importance should be given to text legibility, see http://www.w3.org/TR/SVG11/painting.html#TextRenderingProperty. A workaround could be to convert the outlines to paths e.g in Inkscape, and then animate those. -- Erik Dahlstrom, Core Technology Developer, Opera Software Co-Chair, W3C SVG Working Group Personal blog: http://my.opera.com/macdev_ed - To unsubscribe send a message to: svg-developers-unsubscr...@yahoogroups.com -or- visit http://groups.yahoo.com/group/svg-developers and click edit my membership Yahoo!

Re: [svg-developers] normalizedPathSegList
Hi,
I wrote a partial javascript workaround for the unimplemented
normalizedPathSegList property :
http://jsfiddle.net/ybochatay/AtTND/3/ or https://gist.github.com/1297684
It's not the normalizedPathSegList property as described by the W3C but a
function to convert paths with only M,L,C and Z segments.
You can set the degree of Bezier Curves to approximate arcs (1 will produce L
segments, 2 Q, 3 C), and the defaultFlatness.

Objet: [svg-developers] normalizedPathSegList
Hi,
I try to write a function to update points of a path from a transformation
matrix. It's all ok except for elliptical arcs :
I can't find the correct coefficients for r1 r2 and angle.
Is it simplier to approximate arcs with bezier curves, like the
normalizedPathSegList property would do (but not implemented yet) ?
I wrote an example at http://jsfiddle.net/s32LX/, but I've put the code below
anyway.
Best regards,
Yannick Bochatay
http://ybochatay.fr
SVGPathElement.prototype.mtx2attrs = function(mtx) {
var seg,letter,point,pt={},
angle = Math.atan2(mtx.b, mtx.a),
svg = this.ownerSVGElement,
list = this.pathSegList,
i=0, N = list.numberOfItems;
/* this.rel2abs(); function that change relative paths to absolute */
for (;iN;i++) {
seg = list.getItem(i);
letter = seg.pathSegTypeAsLetter;
['','1','2'].forEach(function(ind) {
if (seg['x'+ind] === undefined seg['y'+ind] === undefined) { return; }
if (seg['x'+ind] !== undefined) { pt['x'+ind] = seg['x'+ind]; }
if (seg['y'+ind] !== undefined) { pt['y'+ind] = seg['y'+ind]; }

point.x = pt['x'+ind]; point.y = pt['y'+ind];
point = point.matrixTransform(mtx);
seg['x'+ind] = point.x;
seg['y'+ind] = point.y;
});
if (angle!==0 (letter === 'H' || letter === 'V')) {
this.pathSegList.replaceItem( this.createSVGPathSegLinetoAbs(seg.x,seg.y) , i
);
}
else if (letter === 'A') {
/*what to do in that case ??

seg.r2 = ?
seg.angle+= angle ?

[svg-developers] Any Maor Advantages of SVG over CSS3 animation
Hi, Well I have been using SVG SMIL for all of my animation needs and have not even studied CSS3 animations in depth. But the more I read about CSS3 animations it seems to be able to do almost everything that SVG is capable of And its been hard to convince people to use SVG Are there examples of animations which is possible to do in SVG but cannot be achieved with CSS3 Or are any major advantages of SVG animations over CSS3 animation All I find is that SVG text is more readable, though it could be because of my experience with SVG - Raks [Non-text portions of this message have been removed] - To unsubscribe send a message to: svg-developers-unsubscr...@yahoogroups.com -or- visit http://groups.yahoo.com/group/svg-developers and click edit my membership Yahoo!
