How can I rotate an image?

Probably not something you will want to do a lot of in ordinary day PHP use, but if you want to rotate an image use the well-named imagerotate function.

This takes the image to rotate, the angle of rotation, and a color to fill the blank space around the rotated image with.

Here's an example:


<?php

$original = imagecreatefrompng("myimage.png");

$red =  imageColorAllocate($original,255,0,0);

imagerotate($original,50,$red);

header("content-type:image/png");

imagepng($rotated);

imagedestroy($original);

imagedestroy($rotated);

?>
