Method Detail

transform

public ImageWritable transform(ImageWritable image,
                               java.util.Random random)

Takes an image and returns a transformed image. Uses the random object in the case of random transformations.

Parameters:

image - to transform, null == end of stream

random - object to use (or null for deterministic)

Returns:

transformed image
