I have a 48 page TeXmacs document, and many of which have images which are screen-shots and so not very high resolution - I think all are less than 800 pixels wide.

The png image source directory and .tm file come to under 9MB, and the document uses only about half of those images.

The exported post-script is 280MB and the PDF is 40MB - which are horrific sizes.

(I'm using latest git repository from git://gitorious.org/texmacs/texmacs.git)

I tried compiling with --enable-pdf-renderer but then pdf export fails with:


** WARNING ** Failed to load AGL file "pdfglyphlist.txt"...
** WARNING ** Failed to load AGL file "glyphlist.txt"...
/home/sam/.TeXmacs/system/tmp/tmp_2009563087.pdf
/home/sam/.TeXmacs/system/tmp/tmp_514256944.pdf
** ERROR ** TFM: Invalid TFM ID: -1

Does anyone have any tips on reducing the PDF size? I tried changing from 600dpi to 300dpi but it only saved 2MB on the PDF

I'm quite certain from the PDF view (where the screen shots are a bit washed out and have a funny interference pattern) that the images are being scaled up and even screened in some way, which is why the post script is so big.
