|
|||
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.
