Why do I have a feeling that the ability to import vector images as

Well that very much depends on what you mean by 'vector images' ;)
The exact Kickstarter stretch goal was this:
Vector Shape Object
Like the graphic object on steroids. Sub-pixel positioning,
shape determined by intrinsic properties (i.e. width of rectangle,
radius of circle etc.). 'Group' type, containing a collection of
shapes to be nested - and imported/exported in a (subset of) SVG.
There is still some more work needed on the widget's architecture to
make this a reality (mainly related to ensuring that the rect of the
widget is determined by its internal geometry, rather than the other
way round which makes BIG difference if you want to do effective and
tile-able affine transformations and avoid animation 'jitter' from
issues surrounding aligning to an integer grid).
However, after spending some time at a weekend recently playing with a
small subset-SVG-parsing library I found, I've come up with this:
https://github.com/livecode/livecode/pull/3089.
This widget enables rendering of simple SVG files consisting of
shapes, paths, transforms, stroke properties, color fills, linear and
radial gradients. This is nowhere near the whole of SVG, certainly,
but is a useful enough subset for icons and such I'd have thought.
I'm currently working out how we can hook such widgets into the 'icon'
mechanism in the engine - meaning that such a widget could be used as
the source of icons in buttons and imgSrcs in fields. Also, it would
be good if there could be some sharing of the parsed SVG data
structures if multiple SVG widgets reference the same file (a bit like
referenced image objects share in-memory representations to minimize
memory cost).
It isn't quite ready for inclusion in a build so it will unlikely be
in DP8 (due this week), I'm hoping it will be ready shortly after that
though.
Just thought people might be interested in this (little) development :)
Warmest Regards,
Mark.
That certainly looks exciting.
What I was wondering about was the ability to make SVG files externally
and then import them, and, similarly, to export
vector graphics from LiveCode in SVG format.
