Hi, it seems I'm having this problem too.

openSUSE 11.1 with kde4.3 (okular)


I created an image with Inkscape that includes pixel data and vector objects.
Making a vector object semi transparent using the "opacity" option of inkscape
creates trouble, using the alpha-channel to do so works.

All of the created pdf documents display just fine using:

- evince
- adobe acrobat reader


opacity creates transparency for the whole vector object including filling and
the lines.

going the alpha-channel way allows for individual control of transparency for
filling and the lines.

in the reference image for opacity also the black outline of the green object
is somewhat transparent (looks gray). in the alpha-channel image only the green
filling is transparent, the green outline has RGBA data of (0,255,0,1) and is
therefore fully saturated / not transparent. The filling has something like
(0,255,0,0.5) and is therefore semitransparent.

All the other parts of the image are just pixel-data and were imported to
inkscape as a png screenshot.
