GD => ImagePNG: No transparency

Hi. I'm afraid I have to say that the transparency in PHP with GD doesn't seem to work. Let me give you an example. The included file, midblob.png, has a transparent area where the color is #bcbcad. Take a look at the following code: if(!isset($text)) $text="Remember to define \$text"; $font = 5; $size = GetImageSize("midblob.png"); // 0=x, 1=y $buffer= Array(5,(($size[1]-ImageFontHeight($font))/2)-3); $width=(ImageFontWidth($font)*strlen($text))+($buffer[0]*2)-1; $if = ImageCreateFromPNG ("midblob.png"); /* Attempt to open */ $im=ImageCreate($width,$size[1]); $resize = ImageCopyResized($im,$if,0,0,0,0,$width,$size[1],$size[0],$size[1]); $colal = ImageColorAllocate($im,0xbc,0xbc,0xad); $trans = ImageColorTransparent($im,$colal); $tc = ImageColorAllocate ($im, 255, 255, 255); ImageString ($im, $font, $buffer[0], $buffer[1], $text,$tc); header ("Content-type: image/png"); ImagePng ($im); Now, the line $colal = ... and $trans = ... shouldn't be necessary because it already has a transparent region. However, ImagePng doesn't seem to output this transparently, but rather as #cccc99. Putting in these two lines doesn't help either. Now, this is really strange. PNG has transparency, and the loaded image does. Why doesn't ImagePng output the transparancy right? Cheers Niklas Saers
