Hi Frans,

> Many thanks for your assistance!

Glad to help! but SVG file format inherent problems
will remain problematic for some time to come:

"Allowing JavaScript within SVG sounds like a
“Wouldn’t that be neat” idea that someone threw
in without much thought about the security
consequences. It makes SVG inherently riskier
than other image formats."

By the way, How many different SVG file versions
already exists? At least 30 or 40 (maybe more) and
the only software that renders correctly most of them
is Google Chrome...

Looks like every Design software produces 3 or 4
(maybe more) different SVG versions... and if you
try to open a SVG produced in one Design program
using another Design program, the results are mostly
problematic and sometimes, the same Design program
that exported a SVG file could not open it correctly again...

Previously, in this mail list, we have discussed about
these (and others) SVG problems so it's not necessary
to repeat ourselves again. Now, I am taking a close look
at Xara 365 (Low cost program) and Microsoft Design
Expression (Free) to create WIX and XAML files compatible
with LiveCode vector graphics.

It's SVG file format that is fickle. I discover this while
updating scripts for stack "SVGL":

When I changed the code to import correctly
one particular SVG file, scripts breaks for
the rest of SVG files and a closer look at the
SVG source does not reveal why this happens.

After some though, I reach the conclusion that
using XAML (a Microsoft format) or WIX (Xara Text format)
would be less stressful and more productive
for LiveCode developers.

For this, just use a text editor like NotePad ++
This Text Editor could find a string in all files
within a folder. This is very useful to find paths
with a fill and a stroke within your thousands of
svg files.

You want to talk with Peter Thirkell and Mark Wieder:

By the way Frans, you could import Adobe Ilustrator files
(version 7or 5.5) into LiveCode and use multicolor gradients
in your ilustrations. Download and test this stack posted
many, many years ago:

Have a nice week!
