gs doesn't seem to like certain pdfs exported from InDesign CS. I've come across the problem before with different files but haven't collected them... I can only supply this one at this time...
Created attachment 2117 [details] This is an example PDF exported from InDesign CS
The file works for me on Windows, display device and GNU/Linux, bmp16m. What command line do you use.
I discovered that the bug has something to do with -dGraphicsAlphaBits=4 *** This bug has been marked as a duplicate of 688378 ***
Matias, Rather that have us try to guess, please give us the command line that you are using. We have already asked once.
Here is the command: gs -sDEVICE=png16m -dGraphicsAlphaBits=4 -dBATCH -dNOPROMPT -dNOPAUSE -q -sOutputFile="test.png" -f "TCM 1850 Three Min Hour_NZH.pdf" It works with -dGraphicsAlphaBits=1
This problem is not a duplicate of the bug 688378. Ghostscript doesn't hang but renders the sample file extremely slow.
