ID: 22388 Updated by: iliaa@php.net Reported By: don at seiler dot us -Status: Open +Status: Feedback Bug Type: GD related Operating System: gentoo linux 2.4.20 PHP Version: 4.3.0 New Comment: Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip I've tried your test script with latest CVS and it works fine. If the problem persists please indicate which GD are you using (built-in or native) as well as what version of libpng your php/gd are linked against?

It outputs no errors but the resulting image is just a single color, which obviously would be nothing like the original photograph. My code works perfectly fine on mod_php 4.2.3 with the gd patch. here is the code I use for png resizing, I actually output to a new image, basically thumbnail creation. $orig_image = "/path/to/orig_image.png"; $thumb_image = "/path/to/thumb_image.png"; /* code to get image dimensions and thumb image dimensions here */ $src_image = imagecreatefrompng($orig_image); $dst_image = imagecreate($dst_width, $dst_height); imagecopyresized($dst_image, $src_image, 0, 0, 0, 0, $dst_width, $dst_height, $src_width, $src_height); imagepng($dst_image, $thumb_image); imagedestroy($src_image); imagedestroy($dst_image); As I said this code behaves fine on 4.2.3. On 4.3.0 and 4.3.1 it outputs a single-color image/png file. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=22388&edit=1
