@ -579,3 +579,4 @@ The arguments for `decode` are as follows:
1. Decode X - where to place the decoded JPEG on screen
2. Decode Y
3. Flags - one of `JPEG_SCALE_FULL`, `JPEG_SCALE_HALF`, `JPEG_SCALE_QUARTER` or `JPEG_SCALE_EIGHTH`
4. If you want to turn off dither altogether, try `dither=False`. This is useful if you want to pre-dither your images or for artsy posterization effects.
