Brent,
If there's enough interest, I'd be willing to contribute the code
changes he made if there's a Mapserver developer/committer willing to
review, upgrade them to v5,and test (and it may require an RFC as there
was a map file addition to OUTPUTFORMAT/FORMATOPTIONS, I think).
I would be willing to review/apply patches on this. I have created a bug
on this http://trac.osgeo.org/mapserver/ticket/2596.
Best Regards
Brent Fraser

Discussed the issue a while ago with Frank Warmerdam. He had less
problems on a LINUX System running on a 64bit machine (he supposes it
could go as high as 25'000 pixels). On Windows 32 it bangs at around
10'000 to 14'000 pixels depending on content. Did not try on Windows 64.
Thanks to advice from the list, I now have huge orthophoto pdfs. But now
I have another problem - using png output, I get nice 24 bit images, but
my pdf output is dithered 8 bit. The relevant part of my map file:
IMAGETYPE png24
OUTPUTFORMAT
NAME png
MIMETYPE "image/png"
DRIVER AGG/PNG
EXTENSION png
IMAGEMODE RGB
TRANSPARENT FALSE
END #outputformat
OUTPUTFORMAT
NAME pdf
MIMETYPE "application/x-pdf"
DRIVER pdf
EXTENSION pdf
IMAGEMODE RGB
FORMATOPTION "OUTPUT_TYPE=RASTER"
TRANSPARENT FALSE
END #outputformat
Removing the FORMATOPTION makes no difference.

The commandline incantation used to produce the images:
$ shp2img -m ddo.map -o ortho.pdf -s 1654 1169 -l DDO -e 659000
6058000 663200 6060970 -i pdf
Does the pdf driver support 24 bit at all? Can I do 24 bit pngs and
assemble the pdfs by hand?
