rgrne Posted November 13, 2007 Share Posted November 13, 2007 I am looking through the PHP manual and am not clear on whether it is possible to do the following with any standard function: I want to merge one image with another, like with imagecopymerge(), but do it in an additive fashion. For example if a pixel in image 1 had a red value (red brightness) of 126, and the same pixel in image 2 had a red value of 20, then the red value of the pixel in the merged image would be 146, etc. As opposed to just replacing the image information in image 1 with that in image 2, or overlaying image 2 as a transparency over image 1.
