Hi, what is the difference of img.width and img.xsize? (reference manual 4.5.2 img.keys) For example, the cow.pdf gives me img.width = 18646779 and img.xsize = 18089984 What are the units? img.width is in sp, what about img.xsize? Patrick

all units in luatex are scaled points the difference is some 8.4 pt which is somewhat weird \the\dimexpr18646779sp/\number\dimexpr1bp \the\dimexpr18089984sp/\number\dimexpr1pt that's pretty close so maybe the xsize (bounding box values) takes the wrong unit when conversion to sp takes place Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

no, just errors in his "don't write mails when tired" mode. Typical case of "Problem Exists Between Keyboard And Chair". I get the same widths here. Sorry everyone. Patrick
