ID: 34131 Updated by: [EMAIL PROTECTED] Reported By: mtjo at conninc dot com -Status: Open +Status: Feedback Bug Type: GD related Operating System: Win 2K PHP Version: 5.0.4 -Assigned To: +Assigned To: pajoye New Comment:
Please provide the sources images, the result images (what you get) and the result you may expect (approximativally). Please use the bundled GD only, your php must be compiled using "--with-gd" not --with-gd=/... Using Gif as output of a filtered image will reduce the quality of any filter... Previous Comments: ------------------------------------------------------------------------ [2005-08-16 02:09:03] mtjo at conninc dot com I tried the script with the same results using the following builds. PHP 5.1 Fri, 12 Aug 2005 23:13:30 +0000 PHP 5.04 Mon, 08 Aug 2005 23:22:28 +0000 I noticed that both of those still use the gd 2.0.28 build. I can't find a complied dll for win32 for the latest 2.0.33 build. Since full gif support was again added at 2.0.28, perhaps it is related to this. Is there a php_gd2.dll for the 2.0.33 lib available? ------------------------------------------------------------------------ [2005-08-15 07:35:47] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php5-latest.tar.gz For Windows: http://snaps.php.net/win32/php5-win32-latest.zip ------------------------------------------------------------------------ [2005-08-15 06:36:30] mtjo at conninc dot com Should say artifact at x,y:2,1 or x,y:2,2 and width varies. ------------------------------------------------------------------------ [2005-08-15 04:29:51] mtjo at conninc dot com Description: ------------ When using the image filters on transparent gif images, it leaves an artifact at x,y:1,1 that is approx 170px long. It appears to be the background color used when the gif is created in a desktop app. This does not affect transparent pngs. This was tested on PHP5.02 and 5.04 with the bundled gd 2.0.28. See http://mike.aplosmedia.com/dev/brightness/test_brightness.php for an example using the brightness filter.

Actual result: -------------- The gif image with filtering and a transparent background with the artifact. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=34131&edit=1
