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

Interview question #1

Since I have been asked to interview experienced PHP programmers, I was preparing few interview questions. I came to know, most of the people ask questions found in the Internet; most of them are like "What is the function used to connect MySQL DB in PHP". Personally, I don't like these types of questions; I'd thought the person must apply ideas what he was taught in colleges--finally I came out with one question: A product vendor has Quantity Vs. Price data like 1 -> Rs. 50 2 -> Rs. 95 3 -> Rs. 140 .... like upto 1 million data. He wants a system, which gives the price when the quantity is provided. For example, if you provide the quantity value as 2, then it should provide Rs. 95. How this system can be designed? As expected, all the people said about using database tables and quering on quantity. I have asked them to find out a system which doesn't use databases--provided the accuracy of the system may not be 100%--it may give at least 90% ac...
