Tk::PhotoRotateSimple - rotate Photos by 90 degrees.
$photo->rotate_simple(direction, [update]);
Tk::PhotoRotateSimple is a Photo method that either flips an image 180 degress, or rotates it 90 degrees clockwise or 90 degrees anti-clockwise.
Algorithm from img_rotate.tcl by Ryan Casey.
The following option/value pairs are supported:
direction can be flip, l90 or r90, for a 180 degree, 90 degree anti-clockwise, or 90 degree clockwise rotation, respectively.
update is an optional boolean parameter. If TRUE, then idletasks() is called to update the image as it's being rotated.
$photo->rotate_simple('l90');
