how about something
\pdfjpgsuffixes{jpg,jpeg,myjpg} \pdfpngsuffixes{png,somepng} \pdfpdfsuffixes{pdf,epdf,fdf}
but you know that the suffixes are used only as a last resort, as first the file headers are checked for the file type (thanks to Heiko!). So e. g. foo.somejpg is a legal name and would still be recognized as .png if it's a png file :-) Regards, Hartmut

ah, i thought so but got an error; i see now that i was testing a faulty graphic sorry for the noice (btw, is there already a better jb2 commandline tool?)

when i test with a unknown format, i get an abort and: Error: pdftex.exe (file ./hakker1b.tif): unknown type of image so, in order to know if a funny suffix is a valid one for pdftex, we need something \pdfcheckimage{somefile.somesiffix} which sets a flag, say \pdfimagecheck 0/1 otherwise there is no way to intercept errors ----------------------------------------------------------------- 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 -----------------------------------------------------------------

which sets a flag, say \pdfimagecheck 0/1
like \pdfretval=-1 not recognized \pdfretval=0 PDF \pdfretval=1 PNG \pdfretval=2 JPG \pdfretval=3 JBIG2 or better 0,1,2,3,4? Regards, Hartmut

right, that would be nice! (0,1,2,...) we should aborted runs as much as possible 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 -----------------------------------------------------------------

Look at CTAN:macros/latex/contrib/oberdiek/bmpsize.pdf.
Here I have implemented some parsing of binary image file types.

Hi Heiko,
Look at CTAN:macros/latex/contrib/oberdiek/bmpsize.pdf. Here I have implemented some parsing of binary image file types.
Ah, now I see what was the exact reason for \pdffiledump -) My understanding is that those macros are supposed to be used exclusively with pdf(la)TeX working in DVI mode, right? If not, what is the profit in PDF mode? Regards, -- Pawe/l Jackowski P.Jackowski@gust.org.pl

Yes, that was my intention.

Hans wanted to have a possibility to check images before
using \pdfximage to avoid errors on unsupported image types.
The method used in bmpsize provides a method to do so.
The other method discussed so far is \pdfcheckimage.
What about \pdfximage that doesn't abort, but print a warning
and \pdfxlastimage returns zero for an invalid image?
Yours sincerely
Heiko
