Hi everyone,
I am trying, but struggling, to find a solution to bug #585286 [1], where exporting a SVG containing a transparent PNG to PS causes excessive blurriness. This is a major bug for me.
I've done as much research as I can do on this bug. After delving through the code base, I think this bug is related to bug #427226 and bug #208217 - apparently Postscript does not support alpha transparency [2], which I think is what is causing the rasterization, and I think it is happening within Cairo. However, it still supports clipping and masking, so as far as I can tell this should be technically possible!
An alternative is simply to increase the resolution of the forced rasterization, but I can't find anywhere in the code to increase this. Would this be part of Inkscape or Cairo?
I've tried using Cairo 1.10.0 with no effect. If anybody has some knowledge of Inkscape/Cairo and can suggest some solutions or even ideas, I would be most grateful.
Thanks Jevon
