Bug #53757 [Bgs]: can't change the background

Edit report at http://bugs.php.net/bug.php?id=53757&edit=1 ID: 53757 Updated by: kalle@php.net Reported by: mesmsgs at gmail dot com Summary: can't change the background Status: Bogus Type: Bug Package: Documentation problem Operating System: Windows 7 PHP Version: 5.2.17 Assigned To: ross Block user comment: N Private report: N New Comment: To be more verbose why this is not working; it works with imagecreate() based instances because it returns a palette based image, whereas with imagecreatetruecolor() that is not the case. The first color allocated in a palette based image will always change the background color (unless overwritten). Where in true color based images (that defaults to a black background) you must create a rectangle to overlay the image to change the background.

In future, please don't submit help requests as bug reports, try the php.general mailing list, an IRC channel or a support site such as StackOverflow. As for your query, try adding this line underneath where you set $bg: imagefill($image, 0, 0, $bg); Regards ------------------------------------------------------------------------ [2011-01-15 16:33:13] ross@php.net Hi, You are correct, the example is wrong as imagecolorallocate only sets the background colour on palette-based images (imagecreatetruecolor should be imagecreate). I'll fix the example. ------------------------------------------------------------------------ [2011-01-15 16:05:44] mesmsgs at gmail dot com Description: ------------ --- From manual page: http://www.php.net/function.imagefilledellipse#Exemples --- I can't change the background color Test script: --------------- <?php // create a blank image $image = imagecreatetruecolor(400, 300); // fill the background color $bg = imagecolorallocate($image, 255, 255, 255); // choose a color for the ellipse $col_ellipse = imagecolorallocate($image, 0, 0, 0); // draw the white ellipse imagefilledellipse($image, 200, 150, 300, 200, $col_ellipse); // output the picture header("Content-type: image/png"); imagepng($image); ?> Expected result: ---------------- The background color must be white Actual result: -------------- Only black background ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=53757&edit=1
