#23482 [Bgs]: Wrong value returned from imageColorTransparent()

ID: 23482 User updated by: author at ninelivescomic dot com Reported By: author at ninelivescomic dot com Status: Bogus Bug Type: GD related Operating System: Linux 2.4.20 PHP Version: 4.3.1 New Comment: Recompiled php, using gd bundled (2.0 compatible). This code: <?php $imgStrip= imageCreateFromPNG("20030509.png"); header("Content-type: image/png"); imagePNG($imgStrip); imageDestroy($imgStrip); ?> Displays the image without the transparency, even though I know it has it. Displaying imageing <IMG> tag looks fine. Previous Comments: ------------------------------------------------------------------------ [2003-05-05 01:34:12] derick@php.net GD 1.6 doesn't support transparency, so that's the problem. Compile PHP with --with-gd (and nothing else behind it) and it will use the internal bundled GD which supports true color images and transparency. ------------------------------------------------------------------------ [2003-05-04 19:04:14] author at ninelivescomic dot com Hi, I'm using php to return the transparent color of a 4-bit png image with binary transparency. This code: /* begin php code */ $imgBase= imageCreateFromPNG("20030429a.png"); print(imageColorTransparent($imgBase)); /* end php code */ prints -1, which I assume means "no transparent color". I'm sure there IS a transparent color. I've tried this with both an optimized and non-optimized palette, same results. I'm using gd library 1.6.2, and can send the image if it helps. ------------------------------------------------------------------------ [2003-05-04 18:24:48] author at ninelivescomic dot com Hi, I'm using php to return the color of a 4-bit png image with binary transparency.
