Product: Ghostscript Reporter: Juliusz Gonera <juliusz.gonera>
Component: Graphics LibraryAssignee: Chris Liddell (chrisl) <chris.liddell>

pdf input

Sample pdf input & resulting jpg output included. 


Invocation:
-----------

    ghostscript-9.04 -q -dBATCH -dNOPAUSE -sDEVICE=jpeg -r200x200 -dJPEGQ=90 -dTextAlphaBits=4 -sOutputFile=page_%02d.jpg pg_0019.pdf

The resulting JPG file has processing artifacts (the title of the page is messed up)

Invoking ghostscript without AA gives the expected result:

    ghostscript-9.04 -q -dBATCH -dNOPAUSE -sDEVICE=jpeg -r200x200 -dJPEGQ=90 -dTextAlphaBits=4 -sOutputFile=page_%02d.jpg pg_0019.pdf

Changed title, looks like this is really a problem with anti-aliasing, since the non-AA output is OK.

I guess once determined this is not a font problem it should go to Michael along with 692808.

Seems to work now - I'd guess as a result of Ray's recent clist fixes.
