Duplicating these very few lines in every svg file is
the easiest and fastest way to jump over this
limitation (until a new version of SVG Multicolor
widget is released). It's relatively easy to create
a Livecode script that automate this task, but
someone in your team should verify that both
svg files (original svg and modified svg for importing
into LiveCode) are visually identical.
In a previous message, you wrote that you have
thousands of files to import into a Livecode app.
This is the reason why I took a closer look at it.
By the way, are you compressing these SVG
paths data before using them inside widgets?
Probably, you could reduce a lot the size of your app
if you compress this SVG path data.
Also, I noticed that your SVG path data uses
3 decimal points (like 51.088)
Please, check if changing for 2 decimal points
(like 51.09) do not change too much the
appearance of your files.
Tell us if this advice works fine in your own project.
You will be saving a lot of time for others that find
these same problems.
