Here's what I'm using at the moment: http://vips.svn.sourceforge.net/viewvc/vips/vips7/trunk/libsrc/conversion/im_falsecolour.c?view=markup The LUT is one I nicked and tweaked from a medical image. It shows values below about 10 in shades of dark purple (this is so you can see any negatives in the image, you need to shift the origin slightly), then higher values as something like a heatmap. Images look nice and the colour range is familiar enough that it's clear to people (usually anyway) which are the cool areas and which are the hotspots. Another popular choice is to walk the edges of an RGB cube in a loop. So you have a red -> magenta gradient, then magenta -> blue, then blue -> yellow etc. This makes for strong colour differences, but it's not obvious from looking at the image which parts are hot or cold. So I prefer heatmaps. John _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
