Hello,

I have problems with scaling of big png images. Scaling works ok with XeTeX, but fails with both pdfTeX and LuaTeX, so it might be a problem in the engine, not necessary in ConTeXt. The image comes out with several cm white border when it should occupy the whole page.

Here are the testing files (temporary location): http://www.mars2008.si/context/

\defineoverlay [MyGraphic] [{\externalfigure[graphic][heigh=\paperheight]}] \setupbackgrounds[page][background=MyGraphic] \starttext whatever \stoptext

+ a big png graphic. When I decrease resolution, the white border around graphic shrinks.

pdfTeX 3.1415926-1.40.9-2.2 (Web2C 7.5.7) This is LuaTeX, Version snapshot-0.30.2-2008102016, build unknown MtxRun | current version: 2008.11.10 21:40 (same problem on TL)

you have a typo: [heigh=\paperheight] must be: height (add a t) the three versions are now unscaled: 3.653.484 luatex.pdf 3.672.711 pdftex.pdf 5.498.535 xetex.pdf 3.654.573 graphic.png although xetex seem sto do something funny with the image (it's the slowest of the three runs so maybe some resampling takes place) 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 -----------------------------------------------------------------

\defineoverlay [MyGraphic] [{\externalfigure[graphic][heigh=\paperheight]}] ^ Missing a 't' here. When I add that, I get a 297mm high by about 190mm wide image. That seems about right to me ?
