From my experience using the "imagecolorallocate" function, the "resource image" parameter does not restrict to which image the color should be applied to. Here is an example: ---------------------------------------------------------------- <?php $image = imagecreatetruecolor(100,100); $image1 = imagecreatetruecolor(100,100); $image2 = imagecreatetruecolor(100,100); $image3 = imagecreatetruecolor(100,100); $some_color = imagecolorallocate($image, 96, 128, 160); imagefilledrectangle($image1, 0, 0, 99, 99, $some_color); imagefilledrectangle($image2, 0, 0, 99, 99, $some_color); imagefilledrectangle($image3, 0, 0, 99, 99, $some_color); imagegif($image1, "image1.gif"); imagegif($image2, "image2.gif"); imagegif($image3, "image3.gif"); imagedestroy($image); imagedestroy($image1); imagedestroy($image2); imagedestroy($image3); ?> ---------------------------------------------------------------- By examining all three images created, it can be found that they are all the same, which brings me back to my point. What is the purpose of the image parameter if the color allocated is not restricted to the image? ---- Server IP: 216.194.113.175 Probable Submitter: 24.239.159.20 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.imagecolorallocate.php Edit -- http://master.php.net/note/edit/62457 Del: integrated -- http://master.php.net/note/delete/62457/integrated Del: useless -- http://master.php.net/note/delete/62457/useless Del: bad code -- http://master.php.net/note/delete/62457/bad+code Del: spam -- http://master.php.net/note/delete/62457/spam Del: non-english -- http://master.php.net/note/delete/62457/non-english Del: in docs -- http://master.php.net/note/delete/62457/in+docs Del: other reasons-- http://master.php.net/note/delete/62457 Reject -- http://master.php.net/note/reject/62457 Search -- http://master.php.net/manage/user-notes.php
