mod_php 4.3.x is failing to properly resize a png image. 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.
