Hi,
I discovered what I think is a bug.
This is the link to download PDF to reproduce.
http://dl.dropbox.com/u/5729426/BUG_GS.zip
The same PDF has been exported from inDesign as PDF/X-1:2001 (PDF 1.3)
and PDF/X-4:2008 (PDF 1.4)
With GS 9.0 and 9.02 the problem is that antialias don't appear on PDF
1.4
With GS 9.04 antialias has been fixed but the output on PDF 1.4 is
completely wrong. See jpeg output for the two files in the link.
I use this command:
/usr/local/bin/gs -dUseTrimBox -dSAFER -dBATCH -dNOPAUSE -
sDEVICE=tiffsep -r300 -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -
dMaxStripSize=8192 -sOutputFile=/tmp/test.tif /Volumes/Vuoto/BUG/
045_PDF_14.pdf
