darkfreaks Posted January 18, 2012 Share Posted January 18, 2012 so i have a class i want to modify on my site that weeds out nudity it is open source and there is a few drawbacks i would like to fix. it lacks the ability to recognize darker skin tones and scan 256 colors for jpeg/gif/png. i tried adding an alpha to the RBG but it is not helping and i have little experience with GD image functions. i don't understand half the code i would like to. if anyone could give me a hand on how i would achieve this please let me know thanks. nudity_filter.class.php CLASS ImageFilter { #R G B var $colorA = 7944996;
