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?
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 -----------------------------------------------------------------
