Easy resize, filter and compression class for images. Check out the examples and source code.
All image manipulations are applied to a temporary image. Only the save() method is permanent.
Requires: PHP5 and GD2 library.
Optional: jpegtran, pngcrush.
Example 1:
include 'ImageUtil.php';
// an absolute URL or path to file. Can be .jpg, .jpeg, .gif or .png
$resize = new ImageUtil('http://www.mikkonen.info/imageutil/images/large/sample_1.jpg');
// set width and height
$resize->resize(320, 240)
// path to file. Can be .jpg, .jpeg, .gif or .png. Directory must be writable.
->save('images/small/output_1.jpg');
Example 2:
include 'ImageUtil.php';
$options = array(
'jpegtran_path' => '/path/to/jpegtran',
'pngcrush_path' => '/path/to/pngcrush',
);
// optionally use different jpegtran/pngcrush path or both
$resize = new ImageUtil('images/large/sample_1.jpg', $options);
// set width, height and optional resize style: 'exact', 'portrait', 'landscape', 'auto' or 'crop'
$resize->resize(320, 240, 'crop')
// filename and optionally the save quality
->save('images/small/output_2.jpg', 70);
Example 3:
include 'ImageUtil.php';
$resize = new ImageUtil('images/large/sample_1.jpg');
$resize->resize(320, 240, 'landscape')
// add watermark image
->watermark('images/large/watermark.png')
->save('images/small/output_3.jpg');
Example 4:
include 'ImageUtil.php';
$resize = new ImageUtil('images/large/sample_1.jpg');
$resize->resize(320, 240, 'auto')
// set filename, transparency, padding and position: 'TL', 'TR', 'BL' or 'BR'
->watermark('images/large/watermark.png', 60, 5, 'TR')

->brightness('-10')
->watermark('images/large/watermark.png')->save('images/small/output_5.jpg');
Example 6:
include 'ImageUtil.php';
$resize = new ImageUtil('images/large/sample_1.jpg');
$resize->resize(320, 240)
// smoothness -12 to 12. Values outside of the range -8 to 8 are usually unusable.
