Here's how you can use the getImageOrientation() information to auto-rotate images to their
correct orientation...
// Note: $image is an Imagick object, not a filename! See example use below.
function autoRotateImage($image) {
$orientation = $image->getImageOrientation();
switch($orientation) {
case imagick::ORIENTATION_BOTTOMRIGHT:
$image->rotateimage("#000", 180); // rotate 180 degrees
break;
case imagick::ORIENTATION_RIGHTTOP:
$image->rotateimage("#000", 90); // rotate 90 degrees CW
break;
case imagick::ORIENTATION_LEFTBOTTOM:
$image->rotateimage("#000", -90); // rotate 90 degrees CCW
break;
}
// Now that it's auto-rotated, make sure the EXIF data is correct in case the EXIF gets
saved with the image!
$image->setImageOrientation(imagick::ORIENTATION_TOPLEFT);
}
Example use:
$image = new Imagick('my-image-file.jpg');
autoRotateImage($image);
// - Do other stuff to the image here -
$image->writeImage('result-image.jpg');
