Hi All,
It seems tk does not like svg images and for Access-Aide_v030.zip I will need to create a scaled png from any .svg images used the epub.
To do that for tkinter I either need heavy svg related code such as librsvg, librsvg2, cairo, and etc just to rasterize an svg.
Instead of those huge libraries, I found a very nice little project called nanosvg on github. This c code is actually in the form of headers that can be easily compiled to create a nano svg2png command line program I wrote called nsvg2png.
Please see the attached Access-Aide_v031.zip and unzip it and look inside the src/ directory.
I can compile the nsvg2png.c using a very simple one-line compile command on osx and all of this works just fine.
Code:
kbhend$ unzip Access-Aide_v031.zip

So if someone has access to an old linux box and compile nsvg2png for 32 and 64 bit executables and can compile it for win32 and win64 and make those builds available to me it would be wonderful!
That way I could add them to Access-Aide plugin (similar to how flightcrew is done).
I have added a zip with sample svg images and a very simple test.epub to test Access-Aide with once you have added the nsvg2png exectuable to the right place.
Thanks in advance for any help.
