We all know that exists \externalfigure[...][...] Now, suppose I'm able to make a buffer with raw data, something like \Raw{<89>PNG^M ^Z ^@^@^@^MIHDR^@^@^@ ^@^@^@ ^H^B^@^@^@^BPXê^@^@^@^AsRGB^@(R)Î^\é^@^@^@ pHYs^@^@^K^S^@^@^K^S^A^@<9a><9c>^X^@^@^@^GtIME^G×^K^T^V^W ^O°<94>^^^@^@^@^YtEXtComment^@Created with GIMPW<81>^N^W^@^@^@^MIDAT^XÓc`^X^E¤^C^@^A6^@^A^ZÕ<8d>^W^@^@^@^@IEND(R)B`<82>} (it's a black png 10x10 pixel, in attach.) How can I use it with, let's say \internalfigure[\Raw][...] ? Of course, write it down to a temp file and then use \externalfigure[temp][..], but I would like to avoid this way . -- luigi

you mean that the bytes should become an image? well, you can try some pdf magic using inline image date in hex format or so, but i never looked into that 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 -----------------------------------------------------------------
