I have a few remarks om the mirror-function:
The cases horizontal and vertical are switched.
1 = vertical and 2 = horizontal.
When I used it there appeared a black lining of 1 pixel on the side or on the top of the picture.
To remove it the function becomes as follows:
<?php
function ImageFlip ( $imgsrc, $mode )
{
$width = imagesx ( $imgsrc );
$height = imagesy ( $imgsrc );
$src_x = 0;
$src_y = 0;
$src_width = $width;
$src_height = $height;
switch ( $mode )
{
case '1': $src_y = $height -1;
$src_height = -$height;
break;
case '2': $src_x = $width -1;
$src_width = -$width;
break;
case '3': $src_x = $width -1;
$src_y = $height -1;
$src_width = -$width;
$src_height = -$height;
break;
default:
return $imgsrc;
}
$imgdest = imagecreatetruecolor ( $width, $height );
if ( imagecopyresampled ( $imgdest, $imgsrc, 0, 0, $src_x, $src_y , $width, $height, $src_width, $src_height ) )
{
return $imgdest;
}
return $imgsrc;
}
?>
