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

From: author at ninelivescomic dot com Operating system: Linux 2.4.20 PHP version: 4.3.1 PHP Bug Type: GD related Bug description: Wrong value returned from imageColorTransparent() Hi, I'm using php to return the 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 transparant color in the image. 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 that helps. -- Edit bug report at http://bugs.php.net/?id=23482&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=23482&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=23482&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=23482&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=23482&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=23482&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=23482&r=support Expected behavior: http://bugs.php.net/fix.php?id=23482&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=23482&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=23482&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=23482&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=23482&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=23482&r=dst IIS Stability: http://bugs.php.net/fix.php?id=23482&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=23482&r=gnused
