Hi Thanh,
when a PDF file with embedded fonts is included by \pdfximage, fonts
will be replaced through lookup_ps_name() heuristics. However it's
actually not checked there whether the font file itself is available.
Problem example:
Some PDF file comes with a Palatino-Roman. TFM entry pplr8r is listed in
the mapfile together with fontfile
Many thanks Hartmut. Martin, shall you apply the patch by Hartmut? Best, Thanh On Thu, Nov 25, 2004 at 02:25:06AM +0100, Hartmut Henkel wrote:

But if the fontfile is not available, the replacement of embedded fonts in PDF files shouldn't be done at all; instead the font coming with the PDF file should be used as is. Below is a quick patch. Only roughly checked.

Hi Hartmut and Martin, please wait, I will take a closer look at the problem. It looks that Hartmut's patch can be improved. Regards, Thanh On Thu, Nov 25, 2004 at 02:25:06AM +0100, Hartmut Henkel wrote:

aaagh, i though that was already fixed ... this is one of the reasons why i've never used those big verbose map files (in the meantime there are other reasons as well) 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 -----------------------------------------------------------------
Hi Hartmut & Martin, here is the version of mapfile.c that I have corrected and tested. Regards, Thanh
