#21624 [Opn]: no transparent Colors in PNG's with Opera 6/7

ID: 21624 Updated by: rasmus@php.net Reported By: Jones@partykel.de Status: Open Bug Type: GD related Operating System: RedHat PHP Version: 4.3.0 New Comment: I guess this is a different problem then than the one described by Steven Brown. Previous Comments: ------------------------------------------------------------------------ [2003-01-13 18:13:18] iliaa@php.net It was my fault libpng 1.2.5 didn't work (header confusion). Once I clean the headers up the code once again worked properly. The only browser with which I can duplicate the problem is Netscape 4.7 on Linux. ------------------------------------------------------------------------ [2003-01-13 18:02:26] Jones@partykel.de The patch doesn't fix this problem :( I changed the code and reconfigured/-compiled, but the example still only works correct in Mozilla. I think the best way would be to use an older version of libpng, e.g. version 1.0.15 from http://www.libpng.org/pub/png/libpng.html, right? ------------------------------------------------------------------------ [2003-01-13 17:54:17] iliaa@php.net The example script works perfectly with: Konqueror 3.0, IE 6.0, Mozilla 1.3a, IE6 and Opera 6.02 (Linux). I am using bundled GD with libpng 1.2.0. Once I compiled libpng 1.2.5 and tried running the same script the image no longer worked in any browser. ------------------------------------------------------------------------ [2003-01-13 17:26:14] rasmus@php.net Sure, but "most other browsers" make up a very very small percentage of what people use. Anyway, a potential patch for this was posted a couple of weeks ago. Try the code referenced in the article below and let us know if it fixes it: http://news.php.net/article.php?group=php.dev&article=93058 ------------------------------------------------------------------------ [2003-01-13 17:23:41] Jones@partykel.de iliaa: <? header('Content-type: image/png'); $Image = imagecreate(300,150); $Body = imagecolorallocate($Image,222,222,222); $Char = imagecolorallocate($Image,10,36,106); imagecolortransparent($Image,$Char); imagechar($Image,5,100,50,"P",$Char); imagepng($Image); ?> rasmus: yeah but I think this problem perhaps only DOESN'T appear with IE & Mozilla but with most other browsers... ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
