#24120 [Opn->Bgs]: imagecopyresized / imagecopyresampled result is bad

ID: 24120 Updated by: rasmus@php.net Reported By: mail at martin-schultheiss dot de -Status: Open +Status: Bogus Bug Type: GD related Operating System: RedHat-Linux 7.3 PHP Version: 4.3.2 New Comment: Didn't I already answer this exact report a while ago? You need to use imagecreatetruecolor() instead of imagecreate() in your code to avoid getting a palletted image.

I have upgraded from php 4.1.x to 4.3.2 with the builtin gd library. Now the result of the imagecopyresized funtion is very bad, and the result of the imagecopyresampled function too. I don`t know how to describe the error exactly, so please take a look at http://www.martin-schultheiss.de/test.jpg and http://www.martin-schultheiss.de/test2.jpg If I dont resize the image but simply read it with imagecreatefromjpeg the result is OK. The code used to create the image is: $source = imagecreatefromjpeg ($filename); $x = imagesx($source); $y = imagesy($source); $max = max($x, $y); $format = $y > $x; //Portrait or Landscape $size = 640; if ($size != $max) { //Image has to be resized if ($format) { $result = imagecreate(($x*$size)/$y,$size); imagecopyresized($result, $source, 0, 0, 0, 0, (($x*$size)/$y) - 1, $size - 1, $x - 1, $y - 1); } else { $result = imagecreate($size,($y*$size)/$x); imagecopyresized($result, $source, 0, 0, 0, 0, $size - 1, (($y*$size)/$x) - 1, $x - 1, $y - 1); } imageDestroy($source); } else { $result = $source; } imagejpeg($result); imageDestroy($result); Bye, Martin ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=24120&edit=1
