[xep-support] Adobe SVG

[Nikolai Grigoriev]

James,

your problem is not related to SVG, but rather to limitations in PNG support in XEP.
The file that you get from Illustrator contains >150 Kb of proprietary Adobe stuff
(non-SVG), plus a raster image in PNG, embedded using 'data:' URI scheme.
 
I attach the PNG image that I extracted. (It is only 3.4 Kb when decoded, and is the 
only meaningful contents of the 190+ Kb SVG file. I wonder why do you need all this 
SVG dressing at all?)

The PNG image uses a transparent background. Unfortunately, PNG transparency 
support in XEP is limited: see http://xep.xattic.com/xep/doc/spec.html#PNG 
for details: we can only map one color as transparent. Your file uses more
transparent colors, and one of them happens to be black; XEP draws it 
as opaque, producing the effect you witness.

Right now, the only feasible way to work around this issue consists in using opaque
PNG with white background. 

Best regards,
Nikolai Grigoriev

JD> Nikolai,

JD> Thank you.  I am sorry to have missed this obvious error.  One more
JD> question:

JD> I have attached a SVG that when viewed by itself in Internet Explorer or
in
JD> a PDF created with FOP maintains a white background.  However, in a PDF
JD> created with XEP the background is black.  Why does this happen?

JD> ...Thank you once again for your time and consideration...

JD> Regards,

JD> James
