Mods & Plugins (Releases & Support) / [MOD]GIF Resizer without loss of Animation
« on: February 19, 2012, 07:39:03 AM »
Hi All,
The gif resizer class was not written by me.
It was taken from here
http://www.phpclasses.org/package/7353-PHP-Resize-animations-in-files-of-the-GIF-format.html.
I have just integrated into the 4images.
Goto Includes/image_utils.php
find the function resize_image_gd
function resize_image_gd($src, $dest, $quality, $width, $height, $image_info) {
global $convert_options;
$types = array(1 => "gif", 2 => "jpeg", 3 => "png");
if ($convert_options['convert_gd2']) {
$thumb = imagecreatetruecolor($width, $height);
}
else {
$thumb = imagecreate($width, $height);
}
$image_create_handle = "imagecreatefrom".$types[$image_info[2]];
if ($image = $image_create_handle($src)) {
if ($convert_options['convert_gd2']) {
imagecopyresampled($thumb, $image, 0, 0, 0, 0, $width, $height, ImageSX($image), ImageSY($image));
}
else {
imagecopyresized($thumb, $image, 0, 0, 0, 0, $width, $height, ImageSX($image), ImageSY($image));
}
if ($image_info[2] == 3) {
$quality = 9;
}
$image_handle = "image".$types[$image_info[2]];
$image_handle($thumb, $dest, $quality);
imagedestroy($image);
imagedestroy($thumb);
}
return (file_exists($dest)) ? 1 : 0;
}
Replace with the below code
function resize_image_gd($src, $dest, $quality, $width, $height, $image_info) {
global $convert_options;
$types = array(1 => "gif", 2 => "jpeg", 3 => "png");
if($types[$image_info[2]]=="gif"){
}
else{
if ($convert_options['convert_gd2']) {
$thumb = imagecreatetruecolor($width, $height);
}
else {
$thumb = imagecreate($width, $height);
}
$image_create_handle = "imagecreatefrom".$types[$image_info[2]];
if ($image = $image_create_handle($src)) {
if ($convert_options['convert_gd2']) {
imagecopyresampled($thumb, $image, 0, 0, 0, 0, $width, $height, ImageSX($image), ImageSY($image));
}
else {
imagecopyresized($thumb, $image, 0, 0, 0, 0, $width, $height, ImageSX($image), ImageSY($image));
}
if ($image_info[2] == 3) {
$quality = 9;
}
$image_handle = "image".$types[$image_info[2]];
$image_handle($thumb, $dest, $quality);
imagedestroy($image);
imagedestroy($thumb);
}
}
return (file_exists($dest)) ? 1 : 0;
}
and download the gifresizer.php

It will resize your Gif Images without loss of animations.
