I don't see any function for this in GD; it looks like you'll have to either
find a third-party library or do it pixel-by-pixel, something like
?php
$width = imagesx($img);
$height = imagesy($img);
for ($j = 0; $j $height; $j++) {
$left = 0;
$right = $width-1;
while ($left $right) {
$t = imagecolorat($img, $left, $j);
imagesetpixel($img, $left, $j, imagecolorat($img, $right, $j));
imagesetpixel($img, $right, $j, $t);
$left++; $right--;
}
}
?
(obviously, a library would be faster, but would essentially do the same
thing).
