           Summary: Text rendering with TextAlphaBits enabled
           Product: Ghostscript
           Version: 9.04
          Platform: PC
        OS/Version: Windows XP
            Status: UNCONFIRMED
          Severity: normal
          Priority: P4
         Component: Text
        AssignedTo: chris.liddell at artifex.com
        ReportedBy: delphian.oracle at gmail.com

Created an attachment (id=8302)
 --> (http://bugs.ghostscript.com/attachment.cgi?id=8302)
Original Font issue.pdf and outputed Font issue.jpg

When I try to render the "Font issue.pdf" attached, the Ghostscript outputs the
text repeated several times staked vertically. See "Font issue.jpg".

The command line is:
gswin32c.exe -dSAFER -dBATCH -dNOPAUSE -sDEVICE=jpeg -r150 -dTextAlphaBits=4
-sOutputFile="Font issue.jpg" "Font issue.pdf"

But if I remove the TextAlphaBits parameters, the file is rendered fine.
