Hello,
lots of my images are huge 200x250mm. I reduce their size with:
\externalfigure[cow][width=20mm, heigth=25mm]
After generating the PDF, the pdf is very huge.
1. Can't Context put the reduced image into the PDF?
2. How can I generate one PDF version for printing (300dpi)
and one for the screen (72dpi)?
I am using Context mk-IV.
Regards
Jannis

no, you need something like ghostscript.
In this case (if you have not problems of space and time) it's better
to transform the pdf in ps with
pdftops yourfile.pdf
and then apply ghostscript to the final ps (see the documentation
about ghostscript)

ghostscript can do that directly with the pdf (no need to go through ps)

yes, but latest ghostscript (ver. 9) sometimes fail when used
directly with pdf.
pdf -> pdftops ->ps ->ghostscript ->pdf seems to be more robust and
gives better results
(although space and time consuming).
