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

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

BehaviorS.js - An alternative to Behaviour.js, event:Selectors and Low Pro libs for unobtrusive JavaScript programming

BehaviorS.js yet another unobtrusive JavaScript library similar to Behaviour.js and event:Selectors but in implementation uses hash based lookup without extending elements; so presumably it should be faster than the rest. The original script and idea was by JLof ; I extended it for DOMContentLoaded support, optimized a bit to avoid scanning of more depths, and added new rules support. I wanted to document the plug a long time and just got time to do it. For the time being BehaviorS.js is available here Update (2006-09-11) : Coralized the link to BehaviorS.js so as to save the load on free brinkster.com webpage Update (2006-09-27) : If the coralized link to BehaviorS.js doesn't work, use http://www21.brinkster.com/guideme/BehaviorS/

RTaKeyman Bookmarklet v2.0

RTaKeyman The above bookmarklet is for English to Tamil transcription. This should work like a Input Method Editor on web page forms. The first version I tried didn't work well and so this bookmarklet version. Version 2.0 2004-12-27 1.0 2004-12-12 Usage Make a bookmarklet with the above link. Point to a web page where you want to enter Tamil characters and click the bookmarklet. This will initialize the keyman for that page. Then start typing on the forms; RTaKeyman will transcribe the characters whenever it sees a space, carriage return and tab. To-do Turning on/off keyman (i.e., to enter both Tamil and English). Help and other user interfaces. Credits Sundar for informing the necessity and for being a beta tester
