Something terrible must be done to png pictures, either in ConTeXt or in luatex. I have the following minimal sample code and picture. I include the png for those who want to check. % Test png addition. \starttext Place png figure.\par \placefigure{Test figure}{\externalfigure[test.png]} \stoptext Without the png-picture it makes an 8KB pdf. But with the png-picture the pdf swells to 1.8MB. And that for a png-picture of only 48KB. Moreover making a zip of all this stuff brought the size back to 110KB. In the log: ConTeXt ver: 2011.11.04 14:15 MKIV fmt: 2011.11.10 int: english/english mkiv lua stats > graphics processing time - 0.001 seconds including tex, 1 processed images What is done with the png and can it be remedied? This swelling up of small picture to such enormous proportions makes the inclusion of png-picture nearly impossible, at least impractable. Hans van der Meer
