I just spotted through Google that Raj Shekhar has quoted my post to comp.lang.php in his Blog Ideas page:

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 $im->setImageIndex($i); $im->writeImage('layer' . $i .

They clearly try and target the web startup "gap" Sites that are innovative (world's first/never seen before kind) SocialAV - World's first and only antivirus building community (by our team) CSSilize - World's first and only project management tool for slicing works (by our team) jobreapr - World's first and only fixed price job search engine (by our team)

100 spits per minute = Madurai!

Whenever I'd praise Madurai people's helping tendency, others would ask me if I like their idlis or noticed anything peculiar. Like I already mentioned, I don't like Madurai foods.
