Convert the attached PDF file to PostScript with

pdf2ps REC10889-2-printout.pdf

Then try to display the resulting file with

gs REC10889-2-printout.ps

Output is as follows:

----------

This happens with Ghostscript 9,04 on Ubuntu Oneiric (11.10).

PostScript resulting from applying pdf2ps to the PDF file.

I'm the 'owner' of the pfd file. Let me know if I can help with further informations.

Comment 3 Ken Sharp 2011-11-14 09:09:41 UTC

This works fine for me with the latest HEAD. I checked with the 9.04 released binary and it fails as described, so it has already been fixed.

Checking with Distiller, the 9.04 release code output fails (as described), and the current HEAD works, so this does seem to have been a fix in pdfwrite/ps2write rather than a fix in the interpreter, but it is possible that the real fix was in some internal area, such as font handling.

Can you find out which change fixed it, so that I can issue an update for Ubuntu Oneiric? Thanks.

This appears to have been a fix to the LZWEncode filter :
42582272f2b4dce1ccd5c600a2d6dc71794b4d3e

I'd strongly recommend taking this patch anyway, its quite an important one.
