Hi,
I have a php resizing code that resizes images and makes a thumbnail from the center of the image.
thumbnail.php
PHP Code:
<?
/**********************************************************
* function resizejpeg:
*
* = creates a resized image based on the max width
* specified as well as generates a thumbnail from
* a rectangle cut from the middle of the image.
*
* @dir = directory image is stored in
* @newdir = directory new image will be stored in
* @img = the image name
* @max_w = the max width of the resized image
* @max_h = the max height of the resized image
* @th_w = the width of the thumbnail
* @th_h = the height of the thumbnail
*
**********************************************************/
function resizejpeg($dir, $newdir, $img, $max_w, $max_h, $th_w, $th_h)
{
// set destination directory
if (!$newdir) $newdir = $dir;
// get original images width and height
list($or_w, $or_h, $or_t) = getimagesize($dir.$img);
// make sure image is a jpeg
if ($or_t == 2) {
// obtain the image's ratio
$ratio = ($or_h / $or_w);
// original image
$or_image = imagecreatefromjpeg($dir.$img);
// resize image?
if ($or_w > $max_w || $or_h > $max_h) {
// resize by height, then width (height dominant)
if ($max_h < $max_w) {
$rs_h = $max_h;
$rs_w = $rs_h / $ratio;
}
// resize by width, then height (width dominant)
else {
$rs_w = $max_w;
$rs_h = $ratio * $rs_w;
}
// copy old image to new image
$rs_image = imagecreatetruecolor($rs_w, $rs_h);
imagecopyresampled($rs_image, $or_image, 0, 0, 0, 0, $rs_w, $rs_h, $or_w, $or_h);
}
// image requires no resizing
else {
$rs_w = $or_w;
$rs_h = $or_h;
$rs_image = $or_image;
}
// generate resized image
imagejpeg($rs_image, $newdir.$img, 100);
$th_image = imagecreatetruecolor($th_w, $th_h);
// cut out a rectangle from the resized image and store in thumbnail
$new_w = (($rs_w / 2) - ($th_w / 2));
$new_h = (($rs_h / 2) - ($th_h / 2));
imagecopyresized($th_image, $rs_image, 0, 0, $new_w, $new_h, $rs_w, $rs_h, $rs_w, $rs_h);
// generate thumbnail
imagejpeg($th_image, $newdir.'thumb_'.$img, 100);
return true;
}
// Image type was not jpeg!
else {
return false;
}
}
?>
and
test.php
PHP Code:
<?php
require 'thumbnail.php';
$dir = '/home/beta/public_html/test/';
$newdir = '/home/beta/public_html/test/new/';
$img = 'test.jpg';
resizejpeg($dir, $newdir, $img, 400, 200, 100, 100);
?>
Why I need:
- Resizing hole directories and skip files if they already exist.
- Naming the thumbnail the same as the image and adding it into the thumbnail directory.
My dirs are like this:
/data/media/40/ (this is one example 40 is the category and other categories are 31, etc.)
/data/thumbnails/40/
Can this be done and I'm willing to pay for this extension
