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

Rajesh,I am experiencing some problem while exporting psd to png ,looses the resolution .Actually I converted 500 dpi psd to png ,but got 72 dpi png .How can keep the resolution ?
Rinto:

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

Don't innovate!

Gopinath had a shocking news for me this morning... the site that we were cloning--cloning with additional features and innovations had just released a new version, but with six features taken from our version. Had we released it some days before, we might have grabbed the innovation pride. But... The weirdest thing was that we're forced to clone including the landing page as in their previous version (and that is the reason for this delay), but when we're doing, they switched to our homepage version! Damn... It doesn't stop here. I was pacifying myself and pushing the software to be released by afternoon--at least then to claim the innovation card. Now Kanagavel has another "good news" for me, that we have to "tune" the product to be exactly as in PSD that would take another week to ship...

The Overrated Tamil Culture

Since the COVID period, I developed an interest in exploring old books from the 1700s to the 1900s through Google Books. I first focused on the celebrated Protestant missionary Ringeltaube, but over time, my curiosity expanded toward understanding the demographics and social practices of that era. In Tamil Nadu, what is often celebrated as "Tamil Culture" revolves around the practice of monogamy, known locally as à®’à®°ுவனுக்கு à®’à®°ுத்தி — meaning one woman for one man. Some even compare this tradition with practices in other states, claiming Tamil culture is especially unique. This sense of pride is particularly strong around Madurai, where people often refer to themselves as “pure Tamil” when compared with neighboring regions like Kanyakumari, whose people they call Malayalis. What’s striking, though, is that this proud image doesn’t always align with historical accounts. A book published in 1885 (I’ve chosen not to mention its title or link to avoid stirring controversy) ma...

Technology prediction for 2018

Bubbles of bitcoin, blockchain, machine learning, deep learning, artificial intelligence and more People usually appreciate me for my predictions on technologies. As I already noted our team will quickly hit the edge case for any use cases and that's supposed to be the reason for my better prediction rate. And so, here are my predictions… Bitcoin bubble When Bitcoin became talk of the town/industry, I informed my boss and colleagues that I find no real use case for this digital currency--except in underground markets like drugs, etc. In fiat currencies, there is at least a way to take legal route, in case, if you've transferred the money and not received the goods. But, in Bitcoin, this is not possible at all as it is not a legal currency. So, if there is no trust, the chances that other person can cheat you by not sending the goods and or not transferring bitcoins after receiving goods. My stand above vindicated by the article Ten years in, nobody has come up with a...
