public class ImagePartition
extends Transformer

Partition an image into smaller subimages. Each input image should have dimensions imageColumns by imageRows, and each output image will have dimensions partitionColumns by partitionRows. The output matrices are row scanned from the top of input image.

Constructor Detail

ImagePartition

public ImagePartition(CompositeEntity container,
                      java.lang.String name)
               throws IllegalActionException,
                      NameDuplicationException

Construct an actor in the specified container with the specified name.

Parameters:

container - The container.

name - The name of this adder within the container.

Throws:

IllegalActionException - If the actor cannot be contained by the proposed container.

NameDuplicationException - If the name coincides with an actor already in the container.

Method Detail

initialize

public void initialize()
                throws IllegalActionException

Initialize this actor.

Specified by:

initialize in interface Initializable

Overrides:

initialize in class AtomicActor

Throws:

IllegalActionException - If a parameter does not contain a legal value, or partitionColumns does not equally divide imageColumns, or partitionRows does not equally divide imageRows.

fire

public void fire()
          throws IllegalActionException

Fire this actor. Consume a single IntMatrixToken on the input. Produce IntMatrixTokens on the output port by partitioning the input image.

Specified by:

fire in interface Executable

Overrides:

fire in class AtomicActor

Throws:

IllegalActionException - If the input size is not imageRows by imageColumns.
