Note Submitter: marshall.AT.byterage.net ---- In response to the note above... ImageColorTransparent() does work on TrueColor images. I have it working myself but I do remember having to add an extra step somewhere. Anyways, here is how I overlay text on a jpeg. Don't forget, you need GD 2.x for true color to work. This example requires TTF support also. // // get src image and dimensions $src_img = ImageCreateFromJPEG("foo.jpg"); $src_w = ImageSX($src_img); $src_h = ImageSY($src_img); // // create empty true color canvas, def bg is black $txt_img = ImageCreateTrueColor($src_w,$src_h); // // define colors $white = ImageColorAllocate ($txt_img, 255, 255, 255); $black = ImageColorAllocate ($txt_img, 0, 0, 0); // // add your white text ImageTTFText ($txt_img, 80, 25, 65, 350, $white, "impact.ttf", "Kung Fu"); // // make black bg transparent ImageColorTransparent($txt_img, $black); // // merge text image onto src image ImageCopyMerge($src_img,$txt_img,0,0,0,0,$src_w,$src_h,30); // 30% opacity 'Now' you can do resizing or whatever and output it. You need to create yet another blank image to resample. (Actually you can resize the image before the text overlay step with some small mods, but its REALLY messy if you want the output size to be dynamic) // // create empty true color canvas for resizing. $dst_img = ImageCreateTrueColor(100,100); // // resize ImageCopyResampled($dst_img,$src_img,0,0,0,0,100,100,$src_w,$src_h); // // output to browser. ImageJPEG($dst_img,'',70); // quality 70 If someone could tell me a shorter way to do this, that would be sweet. The way it is now, it just feels like there is one too many steps to get this done. But I am glad it works at all!
