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

Newspapers: The Hindu vs Times of India

For some years, I was subscribed to The Hindu and Economic Times alone; but when the sales person of Times of India forced me to subscribe with offers, I was kinda reluctant and finally subscribed just for the offer. I didn't like the Arnab Goswami of Times Now and still don't like him. Now, it looks like Times of India is leading in terms of journalism, though I don't like how it's pushing AIADMK. At this moment, Times of India is a clear winner though The Hindu is trying with Wikileaks articles.

Who is RJ Joshua and where is he?

After I have given my Humble Award to RJ Joshua , I have noticed that many people are visiting my blog when they're searching his name in search engines. I used to listen to his English programs on AIR Chennai FM sometime ago; but couldn't get his details on the internet for a long time. Recently I have spotted his photo in potofthots.com and I have stolen that photo too:-) Hope, this little photo of him (with Sanjay Pinto sitting in front) would give good feeling to his fans and well-wishers.

Attraction, Status, and the Curious Pattern Behind Some Marriages

There has been a lot of discussion lately about celebrity divorces. As someone who closely observes human behavior, I have been thinking about a possible pattern behind some relationships. Before explaining my thought, I should mention something about my own background. From childhood, I was never particularly drawn to the idea of physical beauty. In fact, I even had a somewhat negative view of it. This may have come from the value systems around me while growing up. I also remember a religious gathering where someone said that a woman's beauty reflects her inner mind. Even at that time, I instinctively rejected that idea. Over the years, however, I have started noticing certain patterns in couples. When couples walk closely together, sit near each other, and interact affectionately in public, there often seems to be an interesting dynamic. In many such cases, the woman appears more attractive than the man. Sometimes she also seems more powerful in...
