Description Ralph Giles 2006-08-01 17:07:59 UTC

Customer complains of a large file created by the pdfwrite device embedding
AndaleMonoWTG with a simple extended latin postscript input file.

Command line:

c:\bin\gs -IC:\lib\FONTS\Unicode\Resource
 -IC:\lib\FONTS\Unicode -IC:\lib\FONTS -Ic:\lib\PS
 -dDEVICEWIDTHPOINTS=595 -dDEVICEHEIGHTPOINTS=842 -sDEVICE=pdfwrite
 -sOutputFile=sf_alextest_baltic.pdf -dBATCH -dNOPAUSE -dSAFER
 -dWRITESYSTEMDICT -dGHOSTSCRIPT -dSUBSTFONT=/AndaleMonoWTG
 sf_alextest_baltic.ps

I get a 3 MB output file using HEAD on MacOS X, but this still seems very large
if the font is being subset.

sf_alextest_baltic.zip

zip'd pdf output from the customer's patched 8.53. This is the 6 MB version of
the file.

you should not be using -dWRITESYSTEMDICT and -dGHOSTSCRIPT is ignored
by ghostscript.

Comment 4 Ralph Giles 2006-08-02 09:55:25 UTC

Also note that with -dCompatibilityLevel=1.2 I get a 226K file, much better than
3 M. With -dCompatibilityLevel=1.3 I get 3M like the default.

The font file is at casper:/home/support/688799/ .

Comment 6 leonardo 2006-09-07 05:25:28 UTC

Patch to HEAD :
http://ghostscript.com/pipermail/gs-cvs/2006-September/006785.html
Please also note that the revision 6474 (7 monthes ago) fixes another bug, 
which is related to this problem. 

With these fixes GS HEAD produces a 0.5M PDF file instead 6M reported by the 
user. We also opened a new bug 688871 and a new bug 688872 about wishes of 
further improvements.

Closing the bug now because the urgent customer problem is fixed.
