I-NEMO wrote in Sun Jun 22, 2014 6:29 pm:5. - try to get .pdf handling/rendering into Canvas (a simple .pdf viewer like that offered by google, or sort of, might be quick-and-easy- to setup), so to have a decent resolution and smooth details; should this not been possible, we go for .jpg, but hi-res .jpg (from the Charts source!)
I checked the OSG source tree and examples there, the C++ code is directly dealing with an osg::Image and the cpp file is just 100 lines, so it seems fairly compact:
Adapting our CanvasImage code to also support PDF files should be fairly straightforward and not even take very long - so we can revisit this post 3.2 and I can also post some patches to get this started.
