    (I'm not sure if the GD library supports these, but they'd be useful for things like custom borders and corners.)

    (I'm not sure if the GD library supports these, but they'd be useful for things like custom borders and corners.)[/QUOTE]    I added those tonight as well rotate 180 degrees. I thought it was going to be difficult but once I did the first one the other four only took a couple of minute each. [code=php]function Rotate90()
    {
    $w = $this->source_width;
    $h = $this->source_height;
    $slate = $this->slate($h, $w);
    for ($x = 0; $x < $w; $x++)

    {
    for ($y = 0; $y < $h; $y++)

    {
    extract(imagecolorsforindex($this->source, ImageColorAt($this->source,$x,$y)));
    ImageSetPixel($slate, (($h - 1) - $y), $x, ImageColorAllocatealpha($slate, $red, $green, $blue, $alpha));
    }
    }
    imagedestroy($this->source);
    $this->source = $slate;
    $this->source_width = $h;
    $this->source_height = $w;
    } [/code]    I don't know if that is clear. I just created a second image and copied the first to the second one pixel at a time but to different coordinates, then destroyed the first one and substituted it with the second.
