In your case, open a png, check the transparent color. I also need the images you use for your tests. Please provide a link to them. ------------------------------------------------------------------------ [2007-12-05 20:13:30] vbhunt at silverfox dot com Description: ------------ I want to overlay an icon on a button image. The icon is a 32 x 32 pixel png file with transparency. Icon was built in Photoshop 7.01 and tested for transparency on FireFox 2.0.0.11 and IE 7.0.5730.13. The button image is a jpeg. I expected the Icon to overlay part of the jpeg image showing through the transparent png pixels as they do in IE and FF. Instead, the pixels are turned white. I have written and tested the following simple script that reproduces the bug on my system. I expect the script to report the transparent color if there is one. This bug has been reported previously as 12619 which was dismissed as "bogus" but notes that if you have additional information, submit it. When I attempted to comment on it (upon invitation) I get the message, "You can not comment bogus reports or change their status." Therefore I'm re-submitting this ;-) Reproduce code: --------------- <?php function testTransparency( $filename ) { error_log( "Entering testTransparency." ); $rsc = null; if ( $ext = pathinfo($filename,PATHINFO_EXTENSION) ) // if an image switch( strtolower( $ext ) ) { case "gif" : $rsc=imagecreatefromgif( $filename ); break; case "png" : $rsc=imagecreatefrompng( $filename ); break; case "jpg" : $rsc=imagecreatefromjpeg( $filename ); break; } if ( $rsc ) { $tpColor = imagecolortransparent($rsc); $trueColor=(imageistruecolor($rsc))? 'true color':'indexed color'; if ( $tpColor == -1 ) $tpColorString = 'no transparency'; else { $tpColor=(imageistruecolor($rsc))?$tpColor : imagecolorsforindex($rsc, $tpColor); $red = ($tpColor>>16)&0xFF; $green = ($tpColor >>8)&0xFF; $blue = ($tpColor>>00)&0xFF; $tpColorString = 'transparency color: Red=' . dechex($red) . ' Green='. dechex($green) . ' Blue=' . dechex($blue) . ' '; } error_log("$filename $trueColor image has $tpColorString."); imagedestroy($rsc); } else error_log(" $filename is not a supported image."); } ?> Expected result: ---------------- I expected to see: [05-Dec-2007 11:11:09] Entering testTransparency. [05-Dec-2007 11:11:09] buttons/icons/stop1.png true color image has transparency color: Red=0xFF Green=0xFF Blue=0xFF but I got: [05-Dec-2007 11:11:09] Entering testTransparency. [05-Dec-2007 11:11:09] buttons/icons/stop1.png true color image has no transparency. I've tested this on 10 different png icon files with the same result. All of these icons display with correct transparency in Firefox and IE as reported above. Actual result: -------------- [05-Dec-2007 11:52:36] Entering testTransparency. [05-Dec-2007 11:52:36] buttons/icons/alert.png true color image has no transparency. [05-Dec-2007 11:52:36] Entering testTransparency. [05-Dec-2007 11:52:36] buttons/icons/home.png true color image has no transparency. The tests below actually do not have transparency. [05-Dec-2007 11:52:36] Entering testTransparency. [05-Dec-2007 11:52:36] buttons/images/hotmaples1_1.gif indexed color image has no transparency. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43508&edit=1
