Hi,
I found the snippet from beau at dragonflydevelopment dot com useful, but sligthly buggy. There is a
small pixel error ...
I have to subtract "1" from the with in the case 180 and 270:
<?php
switch ($rotation) {
case 90:
imagesetpixel($destImage, ($height - 1) - $j, $i, $reference);
break;
case 180:
imagesetpixel($destImage, $width - 1 - $i, ($height - 1) - $j, $reference);
break;
case 270:
imagesetpixel($destImage, $j, $width - 1 - $i, $reference);
break;
}
?>
