AFAICS the wiki page I linked to correctly describes the behaviour of the save png command now available? No [w h] option is available for png (or jpg, gif, tif, emf). Is there some other location that needs updating? There is an optional compression parameter that you can give for png, specifying how much compression to use. There does appear to be a bug in the processing of that option (and the quality option for jpg). I've submitted a patch for that to the j6 base library. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
