#21624 [Bgs]: no transparent Colors in PNG's with Opera 6/7
ID: 21624 User updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Bogus Bug Type: GD related Operating System: RedHat PHP Version: 4.3.0 New Comment: No I don't think it's an error of Opera. Look at the examples from the png homepage: http://www.libpng.org/pub/png/png-sitemap.html#images e.g.: http://www.libpng.org/pub/png/png-IceAlpha.html http://www.libpng.org/pub/png/png-MagnoliaAlpha.html (this pics use alpha transparency) Opera has no problems to show the images in the correct way. So why the transparency generated with gd isn't shown right? Previous Comments: [2003-01-13 19:06:51] [EMAIL PROTECTED] Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. The images on the specified site work just fine for me in my Opera (6.02 Linux). I'm marking the bug as bogus since I cannot replicate the problem, nor do I see the described problem on the specified site with 4 different browsers. Quircks of win32 Opera are surely not related to PHP. [2003-01-13 18:37:56] [EMAIL PROTECTED] So there isn't a possibility to fix this? iliaa: And it don't works with Opera 6/7 for Windows. If you got to http://www.partykel.de you'll see that in IE/Mozilla, the mainmenu-buttons (generated with gd libpng) at the top are transparent and in Opera they aren't. [2003-01-13 18:15:53] [EMAIL PROTECTED] I guess this is a different problem then than the one described by Steven Brown. [2003-01-13 18:13:18] [EMAIL PROTECTED] 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] [EMAIL PROTECTED] 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? The remainder of the comments for this report are too long.

#21624 [Bgs]: no transparent Colors in PNG's with Opera 6/7
ID: 21624 User updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Bogus Bug Type: GD related Operating System: RedHat PHP Version: 4.3.0 New Comment: Since Version 6.0 Beta 1 Opera fully supports alpha transparency: http://www.opera.com/windows/changelogs/600b1/index.dml So because it worked in previous PHP/GD-versions, I think it is a PHP issue Previous Comments: [2003-01-13 16:20:04] [EMAIL PROTECTED] Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. Given that the behaviour is incositent across browsers and I cannot replicate the described problem in Mozilla or IE 6.0 I'd say this is a broser and not a PHP issue. Perpahps, Opera cannot handle alpha transparency, which is what is causing the problem, this particular type of transparency would not have been avaliable in older GD library. [2003-01-13 15:33:23] [EMAIL PROTECTED] If I generate a PNG with PHP 4.3.0, GD and libpng 1.2.5 and try to use a transparent color with imagecolortransparent(), that doesn't work in Opera (I've tested with Versions 6 7). Sometimes simply nothing happens and sometimes another color is set as transparent. In Mozilla, everything works fine. With the previous Version of PHP and GD 1.8.4 and libpng 1.2.4 it worked in Opera.
