Imagick Image Library
Warning:
This extension is EXPERIMENTAL. The behaviour of this extension -- including the names of its functions and anything else documented about this extension -- may change without notice in a future release of PHP. Use this extension at your own risk. Imagick is a native php extension to create and modify images using the ImageMagick API. ImageMagick® is a software suite to create, edit, and compose bitmap images.. It can read, convert and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Copyright 1999-2007 ImageMagick Studio LLC, a non-profit organization dedicated to making software imaging solutions freely available. Imagick makes image manipulation in PHP extremely easy through an OO interface. Here is a quick example on how to make a thumbnail: Example 1028. Creating a thumbnail in Imagick<?php Using SPL and other OO features supported in Imagick, it can be simple to resize all files in a directory (useful for batch resizing large digital camera images to be web viewable). Here we use resize, as we might want to retain certain meta-data: Example 1029. Make a thumbnail of all JPG files in a directory<?php Table of Contents

The fit functionality of thumbnailImage doesn't work as one would anticipate. Instead, use this to make a thumbnail that has max of 200x82: // Create thumbnail max of 200x82 $width=$im->getImageWidth(); if ($width > 200) { $im->thumbnailImage(200,null,0); } $height=$im->getImageHeight(); if ($height > 82) { $im->thumbnailImage(null,82,0); } gmail dot com
In case anyone is wondering about some examples for Imagick usage, take a look at Mikko Koppanen's blog at http://valokuva.org/?cat=1.

Here is an example on how to take an image that is already in a string (say, from a database), and resize it, add a border, and print it out. I use this for showing reseller logos // Decode image from base64 $image=base64_decode($imagedata); // Create Imagick object $im = new Imagick(); // Convert image into Imagick $im->readimageblob($image); // Create thumbnail max of 200x82 $im->thumbnailImage(200,82,true); // Add a subtle border $color=new ImagickPixel(); $color->setColor("rgb(220,220,220)"); $im->borderImage($color,1,1); // Output the image $output = $im->getimageblob(); $outputtype = $im->getFormat(); header("Content-type: $outputtype"); echo $output; |
