There is a small q+d patch on my homepage at http://www.circuitwizard.de/pdftex/patch5/index.html which tries to embed PNG files natively, without the usual slow decompressing + compressing steps done by pdftex---only if the PNG image type allows that. This usually results in a smaller overall PDF file size, as the original line-by-line predictor type informations from the PNG image are carried over into the PDF file. And the PNG embedding is speedier. Best Regards, Hartmut P.S. The newest libtiff comes with a tiff2pdf program. Quite handy.

ha, good that we dropped tiff support. If there is a reasonable png2pdf program, should we drop PNG support as well? Regards, Thanh

Well, there is png2pdf: http://png2pdf.sourceforge.net/ We should keep png; it works quite well compared to the tiff support when I removed it. And we need some losless image support. :-) Best regards Martin -- Martin Schröder, ms@artcom-gmbh.de ArtCom GmbH, Lise-Meitner-Str 5, 28359 Bremen, Germany Voice +49 421 20419-44 / Fax +49 421 20419-10 http://www.artcom-gmbh.de

indeed; also, tiff was always experimental; also, we cannot permit such downward compatibility losses Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
