poppler doesn't (neither does xpdf) implement image transparency using image masks. It would be nice to have, but it's not actually a bug, it's just not supported.
Hrm. It's a missing feature, technically speaking, but to the user it is very definitely a bug. :/
Created attachment 2886 [details] Canon EOS 20D instruction manual An additional PDF with basically the same problem. The work-around is, of course, to not use popper unless at times when one's feeling particularly idealistic. ;)

Created attachment 4189 [details] svg file, which can be converted with svg2pdf to reproduce problem with transparency i am attaching svg file, which contents is rendered as black boxes when converted to pdf. i think it is a problem with transparency, too. you can convert from svg to pdf using svg2pdf or inkscape. in xpdf 3.01 it renders ok, but in xpdf 3.00 there are black boxes, too. using evince 0.4.0, poppler 0.4.3.
xpdf 3.01 is imported, is this problem fixed already?
No, it still isn't fixed (poppler & evince both at 0.5.0). Didn't you checked attrached PDF?
Nickolay, as I can see - sxi.pdf works fine with xpdf 3.01 but fails with evince 0.5.0 + poppler 0.5.0 - pdf file created from attached svg file works fine with evince 0.5.0 + poppler 0.5.0
CairoOutputDev needs to implement drawMaskedImage and drawSoftMaskedImage. They're implemented in SplashOutputDev (so xpdf/poppler works) but it won't be a straightforward port.
