Method Detail

transform

public final ImageWritable transform(ImageWritable image)

Specified by:

transform in interface Operation<ImageWritable,ImageWritable>

transform

public final ImageWritable transform(ImageWritable image,
                                     Random random)

Description copied from interface: ImageTransform

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

Specified by:

transform in interface ImageTransform

Parameters:

image - to transform, null == end of stream

random - object to use (or null for deterministic)

Returns:

transformed image

doTransform

protected abstract ImageWritable doTransform(ImageWritable image,
                                             Random random)

query

public float[] query(float... coordinates)

Description copied from interface: ImageTransform

Transforms the given coordinates using the parameters that were used to transform the last image.

Specified by:

query in interface ImageTransform

Parameters:

coordinates - to transforms (x1, y1, x2, y2, ...)

Returns:

transformed coordinates

getCurrentImage

public ImageWritable getCurrentImage()

Description copied from interface: ImageTransform

Returns the last transformed image or null if none transformed yet.

Specified by:

getCurrentImage in interface ImageTransform

Returns:

Last transformed image or null
