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 Try the newly added 4th argument: imagerotate($rsr, $angle, $bg_color, $keeptransparency); However, note that this is interpolated colors in the destination images (rotated), meaning that if the original image has some antialiased artifacts with the bgd color, you will notice them in the rotated image (in your case, a white border), not much can be done against that. --Pierre Previous Comments: ------------------------------------------------------------------------ [2005-09-01 21:41:26] [EMAIL PROTECTED] Description: ------------ Imagerotate doesn't preserve transparency information. Next image was used in example below: http://img24.imageshack.us/img24/228/spritepaw8alpha2os.png Reproduce code: --------------- <?php $sprName = "sprite_paw8_alpha.png"; $spr = imagecreatefrompng($sprName); //create sprite object //get sprite's transparent color $sprTransparent = imagecolortransparent($spr); //sprite rotation $rotate = 15; //rotate sprite, ?keeping transparent pixels $spr = imagerotate($spr, $rotate, $sprTransparent); header("Content-type: image/gif"); imagegif($spr); imagedestroy($spr); ?> Expected result: ---------------- Rotated image with transparent background. Actual result: -------------- Rotated image with black background. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=34336&edit=1
