Venetian blind effect - Anthony 17/6/2008
This uses the imagemagick miff which saves the image into the memory and then the Unix "pipe".
<?php$cmd = " -size 2x4 xc:none -fill black "." -draw \"rectangle 0,0 2,1\" miff:- | "." composite -dissolve 30% -tile - input.jpg ";exec("convert $cmd output.png");?>

For more examples and information check out the main Imagemagick section.
