Description Marcos H. Woehrmann 2008-03-25 10:53:07 UTC

The attached PDF file (which is a simplified version of the file originally submitted by the customer) 
renders with Ghostscript gs8.62 and head (r8604) with the background behind the text in black instead of 
white,  Both Acrobat 8 and Apple Preview renders the file correctly.

The command line I'm using for testing:

  bin/gs -sDEVICE=tiff24nc -o test.tif ./Temp00000b.pdf

Comment 2 Alex Cherepanov 2008-03-27 20:07:13 UTC

One of the images in the file has SMask but this fact is not detected by
pageusestransparency procedure.

Comment 3 Alex Cherepanov 2008-03-27 23:40:25 UTC

Improve detection of transparency usage. Search for transparency features in
the resource chain of annotation appearance streams.

The patch is committed as a rev. 8612.
Regression testing shows no differences.
