Flate = 3

Flate compression.

Jpeg = 6

JPEG compression. Does not support transparency.

LzwOptimizedPredictor = 5

Predictor selection is more complicated and should result in smaller image sizes but taking more time.

None = 1

Saves raw image bytes resulting in bigger PDF file sizes.

Rle = 2

Run Length compression.
