Re: Create image from SVG widget

[Brian Milby via use-livecode]

If it is placed in a library that is distributed with the IDE, then you 
wouldn’t need to worry about the LCB side of it.

If it is easy enough to translate a path in the compile code, LCB wouldn’t be 
needed at all.  I just didn’t spend enough time to figure it out.

Re: Create image from SVG widget

[Brian Milby via use-livecode]

It doesn’t require an actual file, just an XML document.  I posted LCB code to 
convert the SVG path to what is needed for the compile.  It will require an 
engine change or LCB to get the path translated to remove top/left extra space.

I think the best way would be to update one of the LCB libraries to include my 
handler and the add a handler to the drawing library that uses it to do the 
compile.

Now that I’m writing/thinking, it might could be done inside the LCB code with 
a call to the compile script.

You do not need a file, but you do need additional code.  I found a handler 
from a Sep 2018 thread that wraps a path to form the input needed for the 
compile.  LC Mark mentioned an internal call that could enhance the process but 
I didn’t see any code that leveraged it.  Let me take a crack at it and see 
what I come up with.

Re: SVG widget and grab me command

[Tore Nilsen via use-livecode]

My mistake, I meant handles, not handlers. The widgets are used to display 
chess pieces. The actual script «controlling" each widget/group is a behavior, 
where the script itself resides in a button script.

Re: SVG widget and grab me command

[Tore Nilsen via use-livecode]

Thanks for your explanation. Since my student does not need any handlers (in 
fact would not want any handlers added to the widgets), the examples from 
«ControlHandles89» could not be used.

The simple solution was to «group» each individual SVG widget and add the grab 
me command to the group.

Widgets are not ordinary controls.
So this is not a bug, rather a missing feature (the widget
author will have to implement an own "grab"-handler).
The widget passes mouseDown but not in a way that "grab" can
be used. MouseMove isn't passed (=> not usable) at all.

You could try "ControlHandles89" from "Sample Stacks" or
http://livecodeshare.runrev.com/stack/902/
which adds handles to widgets for resizing and grabbing.
(Or use a solution similar to that).

SVG widget and grab me command

[Tore Nilsen via use-livecode]

When one of my students tried to use grab me command in a mouseDown handler on 
a SVG widget, some strange things happened. In run-mode, the script did not 
work as expected. The widget would not move with the mouse. When switching back 
to edit mode, the widget started to move with the mouse once the cursor entered 
the rect of the stack. It was impossible to put down the widget afterwards.

The same thing happened when we tried to make the widget follow the mouse in a 
mouseMove handler. Has anyone else come across this?

What you want is  probably that the widget resizes its
rectangle *minimally* so that the size of the svg remains
unchanged when rotating. That's not (yet) available in LCB.

But you can compute the needed rectangle and resize the
widget accordingly by LC Script.
(I did that for a rotating text widget).

Re: Let's rotate an SVG widget

[hh via use-livecode]

Maintain aspect ratio is for resizing the svg object
when resizing the widget.

What you want is  probably that the widget resizes its
rectangle *minimally* so that the size of the svg remains
unchanged when rotating. That's not (yet) available in LCB.

But you can compute the needed rectangle and resize the
widget accordingly by LC Script.
(I did that for a rotating text widget).

Re: Let's rotate an SVG widget

I went here: https://livecode.com/livecode-widgets-svg-path/

and came across maintainAspectRatio which sounds dead groovy:

setthemaintainAspectRatio ofwidget "hour" totrue
settheangleofwidget "hour" toINC

but it didn't maintain its aspect ratio . . .

I added my updates to that forum post, building on Peter's fine work.
Allows for my flexibility for svg files from other formats.
The lack of xml and word chunk processing in LCB is a severe handicap.

Yes. If you define path by "connected points" (I haven't seen
that in any specification).



SVG paths are an extension of PostScript paths - these are a sequence
of disjoint subpaths. You can have as many such subpaths as you like.

However, they are always rendered as 'one thing' which is where the
fillRule (evenodd or nonzero) and direction of the subpaths comes into
play to decide which parts are filled and which parts are not.

A good illustrated example is given here:

Yes. If you define path by "connected points" (I haven't seen
that in any specification).

But your example is a fine example for a nice option we have
with the LC-SVG icons:
We can simply "merge" some of them to one icon by merging their
(textual) iconPathes.

Your letter "R" is not part of the (single) path.

The widget SVG Icon is set up to display at most ONE SINGLE path,
no matter where the path comes from.

The format must according to dict fulfill the SVG specifications
https://www.w3.org/TR/SVG/paths.html#PathData.

Colin's _path_ demo contains also elliptical arcs (a- or A-Elements).

That's what LC obviously does not (yet) support in LC 9.0.0-dp6.

Re: Drop Shadow Not Available on SVG widget

[hh]

DropShadow can be made available in LCB, just extend
the widget with your code for that and rebuild it.
Or:
Use the SVGText-widget, which has (fixed) dropshadow.
For that do in the Property Inspector of the SVGText-widget
[1] check "useShadow" in section "Colors",
[2] copy the iconPath of the SVGIcon-widget to the
svgTextPath (section "Contents"),
[3] check "inputPathInstructions" (below the svgTextPath).

Drop Shadow Not Available on SVG widget

[Sannyasin Brahmanathaswami]

I guess I can understand why the SVG which has no graphic effects available.

OTHO If one has a series  of icons along a toolbar, mixing different control 
types, we need it.

You can set graphic effects for

button 1 (which uses a letter for it's label)   # nice drop shadow
button 2 (which uses a icon ) # nice drop shadow
Widget 3 (acting as a button) # we are stuck now: no drop shadow available

Any work arounds?

is it worth asking for an enhancement?  or is this just "not going to happen, 
no way, no how" because of the nature of SVG inside a widget?

Re: Apply an SVG Widget as a single object in a stack to multiple buttons as icon?

[Richmond]

Well: Let's start at the beginning (Yes, I know; that's oozing with 
originality; sorry.):


1. How does one import an SVG image in the IDE?

[By that I don't mean "fekking around" extracting path data and so on].

2. I popped the 'black star' SVG thingy on a stack and tried to set a 
button up so

it had that SVG as an icon . . . like this:

The SVG had an ide assigned of 1003

The prefs palette would not allow me to set the button's icon to 1003.

3. Is it just me, or is the 'thing' with SVG images still in a sort of 
alpha-beta state?

--

4. I thought I'd try a "different way", and to test that I imported a 
PNG image

called "INKKY.png" [don't ask] and executed this in the MessageBox:

set the icon of btn "BT" to the id of img "INKY" . . . and, 
unsurprisingly it worked.


So:

5. set the icon of btn "BT" to the id of widget "SVG icon" . . . Humph: 
obviously expecting a bit much.

There are 2 questions that I can think of just now:

6. Why bother with using an SVG image as an icon when it's dead easy to 
convert it into a PNG
image using any number of image processors, and then importing that into 
one's stack?


6.5. [possible answer] Because if one sets one's stack up to scale to an 
end-user's monitor a PNG

might get jaggy round the edges.

7. When (?) are we going to be able to go /Menu/File/Import as 
Control/Image File...
and an SVG file will be imported just the same as a GIF, JPG, PNG or one 
of those funny image formats nobody has heard of?

We can't?

What's the point of an SGV Icon object if it can't be used as an icon?

Apply an SVG Widget as a single object in a stack to multiple buttons as icon?

[Sannyasin Brahmanathaswami]

With images we can import a raster "object" and then set the icon of a button 
to that image.

Wouldn't it be nice to be able to do the same with a SVG file?  Theoretically 
then the different buttons calling that same (0ne and one only in the stack) 
SVG image as their icon could have varying sizes, but the image would still be 
perfect (since icon is rendering a vector object)

What is the use case? If our designers do cool things in illustrator. 
(hopefully one day we can support multiple colors and gradients in LC SVG 
widgets)  we would just like to save them once and call them into various 
contexts. Scenarios would include background on text button links, small icons 
on maps that would appear perfectly at any zoom level etc.  Even better: have a 
label that can sit on top.

see:

http://wiki.hindu.org/screenshots/vector-btn-bkgnds.jpg

the ragged "patches" behind the text/button links are vector… previously I was 
forced to save as PNG.. set the icon to a pattern, use the png as the pattern 
set icon gravity … careful manipulation of margins… But, advantage was: it was 
still a single object in the stack and the PNG could be applied to multiple 
buttons.

now I'm trying to see how I can get these as single SVG object(s)without having 
to have

a) SVG widget underneath
b) text button on top
So, we all know this -- except for lurking newbies, so FWIW we will "declare" 
the obvious:

currently the icon of a button set to an image requires that image to be the 
precisely sized to meet the button's display size/rendering requirements. I 
have in some scenarios, dynamically resized images that are used for button 
icons on different cards, so that they appear correctly. Goal was, obviously 
not to have multiple instances of the same image across multiple cards.

One might have a case where there were large buttons on a card… then the image 
for the icons may need to be set at e.g. 128 X 128.. then if you displayed them 
on a grid on another card you might down size them dynamically to 32 X 32.

Problem is of course there is always a break down of the image quality, even if 
set to "best" with SVG that should go away.

Is anyone doing this? I visualize a scenario where one dynamically sets the SVG 
path to a string that might be, for example, stored as a custom property 
(instead of on an "image resources" card)

Would it be worth it to make this a feature request, so that this icon 
assignment would be indifferent to the image format .png, svgwidget, jpg?  Then 
you could still work with "the button name" programmatically.
