imagejpeg($image, $to, $quality) Output JPEG file from the given image
imagepng($image, $to, $quality, $filters) Output or save PNG file from given image
imagegif($image, $to) creates the GIF file
imagecropauto($image, $mode, $threshold, $color) Automatically crops an image according to the given mode. Modes are IMG_CROP_DEFAULT, IMG_CROP_TRANSPARENT, IMG_CROP_BLACK, IMG_CROP_WHITE, IMG_CROP_SIDES, IMG_CROP_THRESHOLD
