- #
- # Optional "quality" parameter (defaults is 3). Fractional values are allowed, for example 1.5. Must be greater than zero.
- # Between 0 and 1 = Fast, but mosaic results, closer to 0 increases the mosaic effect.
- # 1 = Up to 350 times faster. Poor results, looks very similar to imagecopyresized.
- # 2 = Up to 95 times faster. Images appear a little sharp, some prefer this over a quality of 3.
- # 3 = Up to 60 times faster. Will give high quality smooth results very close to imagecopyresampled, just faster.
- # 4 = Up to 25 times faster. Almost identical to imagecopyresampled for most images.
- # 5 = No speedup. Just uses imagecopyresampled, no advantage over imagecopyresampled.
