Imagick::cropImage
I found a relevant posting complete with demo code at this site:
http://valokuva.org/?p=8
Sample code goes like this:
<?php
/* Read the image */
$im = new imagick( "test.png" );
/* create the thumbnail */
$im->cropThumbnailImage( 80, 80 );
/* Write to a file */
$im->writeImage( "th_80x80_test.png" );
?>
This is a specialization of the cropImage method. At a high level, this method will create a thumbnail of a given image, with the thumbnail sized at ($width, $height).
If the thumbnail does not match the aspect ratio of the source image, this is the method to use. The thumbnail will capture the entire image on the shorter edge of the source image (ie, vertical size on a landscape image). Then the thumbnail will be scaled down to meet your target height, while preserving the aspect ratio. Extra horizontal space that does not fit within the target $width will be cropped off evenly left and right.
As a result, the thumbnail is usually a good representation of the source image.
