Thanks that could be useful... BTW where to you store this kind of snippet We need an online repository for scripts like this... something simpler than GIT,
Actually determining the luminance algorithm is pretty straight forward... even easier than this formula.. but how do you get the color a specific pixel in an image?

I'm sorry I can't give credit, I should have saved that. Determine whether to show white or black text against a colored background: function calcLuminance pRGB -- wikipedia: Y = 0.2126 R + 0.7152 G + 0.0722 B put item 1 of pRGB * 0.2126 into tR put item 2 of pRGB * 0.7152 into tG put item 3 of pRGB * 0.0722 into tB if sum(tR,tG,tB) > 125 then return "black" else return "white" end calcLuminance _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
