Converting PSD with PHP/ImageMagick

After seeing feature rich options in Imagick PECL extension at Mikko Koppanen's (the author) website and also impressed with ImageMagick's features, I have decided to use it for the PSD to XHTML conversion website that I'm architecting and managing.

Since, the team wants programming help for converting PSD images, I have tried it (documentation is sparse on PSD handling)

Converting PSD to PNG/JPEG/etc


Note that, flattenImages() is needed for layered/multi-page PSD file.


<?php
$im = new Imagick('test.psd');
$im->flattenImages();
$im->setImageFormat('png');
$im->writeImage('test.png');
?>



Extracting PSD layers


One by one



<?php
$im = new Imagick('test.psd');
$im->setImageFormat('png');
for ($i = 0, $num_layers = $im->getNumberImages(); $i < $num_layers; ++$i) {
$im->setImageIndex($i);
$im->writeImage('layer' . $i . '.png');
}
?>


Note that, there is a better version below

In a single call with writeImages()



<?php
$im = new Imagick('test.psd');
$im->setImageFormat('png');
$im->writeImages('layer%d.png', true);
?>


Note: Second parameter of writeImages() is for adjoin

Bug

While doing so and comparing with the results of XnView, I have noted a same problem/issue as mentioned here in the forum--that is, most of the extracted layers/images are distorted. By the way, I have tried in WAMP and yet to try it in LAMP

Rinto:

After second thought, you'd be better off with the command line "convert" instead of this extension

PHP 10 miles

It's glad to know PHP is been alive for 10 years. PHP originally written by 27-year-old Rasmus Lerdorf and released in June 8, 1995 is now in PHP 5.0.4. I think, I hadn't seen any computers when PHP 1.0 was released (in 1995). My memory says I picked PHP around late 2000 or early 2001. One important thing I have noticed at this time is: PHP 1.0 wasn't a bunch of Perl scripts as many often quote; it was " set of small tight cgi binaries written in C " Links news: 3r7pgp$aa1@ionews.io.org Announcing the Personal Home Page Tools (PHP Tools) version 1.0.
