Previous Comments: ------------------------------------------------------------------------ [2003-01-20 12:20:57] [EMAIL PROTECTED] I'm using the bundled library. And since there seems to be no way to upload them (even though they're about 5K total), I'll just put the images here: Orc: http://homepage.mac.com/tuxedobob/Orc.png Board: http://homepage.mac.com/tuxedobob/Board.png ------------------------------------------------------------------------ [2003-01-20 09:39:44] [EMAIL PROTECTED] Please provide the two images used in your example. Also, are you using the bundled GD library or the non-bundled one? ------------------------------------------------------------------------ [2003-01-20 02:28:08] [EMAIL PROTECTED] In the following script: <?php $image2 = ImageCreateFromPNG('images/Monsters/Orc.png'); $image = ImageCreateFromPNG('images/Board.png'); $black = ImageColorAllocate($image2, 0, 0, 0); imagecolortransparent($image2, $black); imagecopy($image, $image2, 40*2+8, 40*2+8, 0, 0, 39, 39); header("Content-type: image/png"); ImagePNG($image); imagedestroy($image); imagedestroy($image2); ?> what I expect to happen is that the black in the 'Orc.png' image will become transparent when it is copied onto 'Board.png'. This doesn't happen. The transparency is not recognized at all. More info: Orc.png is a 2-bit PNG, with black occupying two of the colors. (It doesn't work even if it only has one.) Board.png is a 4-bit PNG with 6 distinct colors (11 copies of black). If I change the line to imagecolortransparent('$image2, imagecolorat($image2, 0, 0); it works correctly. If I change the line use either 2 or 3, as in imagecolortransparent('$image2, 3); it works depending on which black (index no. 2 or 3) is actually in the image. There may be no way around this except to have imagecolortransparent check by RGB values rather than an index number. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=21763&edit=1
