This works great! But I need it to do a -90 degree as well.


<?

$img_sorgente="ruotami.jpg";

$size = GetImageSize($img_sorgente);
$tot_x = $size[0];
$tot_y = $size[1];

$img_risulta = ImageCreate ($tot_y,$tot_x)

$img_sorgente=ImageCreateFromJpeg($img_sorgente);

for($i_x=0;$i_x<$tot_x;$i_x++){

        for($i_y=0;$i_y<$tot_y;$i_y++){      

        $ris_x=$tot_y-($i_y+1);
        $ris_y=$i_x;
       
        imagecopy($img_risulta, $img_sorgente,
$ris_x,$ris_y,$i_x,$i_y,1,1);
       

        } // Y

} // X

Imagejpeg($img_risulta);

?>

Try to replace

$ris_x=$tot_y-($i_y+1);
$ris_y=$i_x;

with

$ris_x=$tot_y;
$ris_y=$i_x;

Almost there although it seems to rotate 90 then mirror that. Not rotate -90.

Points increased for trying!
