This bug makes it impossible to read some PDF with transparency.

http://promo.sico.ca/en/download/pro_con_evo_post_trial.pdf is an example.

This bug is back...

Example: http://www.a-pdf.com/watermark/examples/sample(rotatetext).pdf

while it should look like the preview: http://www.a-pdf.com/watermark/example.htm (2nd row, 3rd column).

Actual results:

PDF renders but watermark is topmost layer and doesn't support opacity.


Expected results:

The watermark should be bottommost layer and be almost transparent.

This bug makes it impossible to read some PDF with transparency.
