Class PixelleTransformer

java.lang.Object
  com.mebigfatguy.pixelle.PixelleTransformer

public class PixelleTransformer
extends java.lang.Object

transforms one bitmap into another based on the algorithms defined by the user.

Constructor Summary

PixelleTransformer(PixelleImage[] images, java.util.Map<PixelleComponent,java.lang.String> algos, ImageType imageType, java.awt.Point newDimension)
constructions a transformer given a source bitmap and algorithms

Method Summary

static java.util.Map<PixelleComponent,java.lang.String>	getSampleTransform() builds a sample set of algorithms that creates a 'pleasing' image
PixelleImage	transform() transforms the image into a destination image based on the algorithms supplied.

Constructor Detail

PixelleTransformer

public PixelleTransformer(PixelleImage[] images,
                          java.util.Map<PixelleComponent,java.lang.String> algos,
                          ImageType imageType,
                          java.awt.Point newDimension)

constructions a transformer given a source bitmap and algorithms

Parameters:

images - the source images

algos - the algorithms for the color components

newDimension - the desired dimension of the output image

Method Detail

getSampleTransform

public static java.util.Map<PixelleComponent,java.lang.String> getSampleTransform()

builds a sample set of algorithms that creates a 'pleasing' image

Returns:

a set of transformation algorithms

transform

public PixelleImage transform()
                       throws PixelleTransformException

transforms the image into a destination image based on the algorithms supplied. It does this by generating classes that implement the PixelleExpr interface, and dynamically loads them to create the new pixel values.

Returns:

the destination bitmap

Throws:

PixelleTransformException - if a failure occurs reading, writing or transforming a bitmap
