Package ca.cgjennings.graphics.filters

Class PixelArtUpscalingFilter

java.lang.Object

ca.cgjennings.graphics.filters.AbstractImageFilter

ca.cgjennings.graphics.filters.PixelArtUpscalingFilter

All Implemented Interfaces:

java.awt.image.BufferedImageOp

public class PixelArtUpscalingFilter
extends AbstractImageFilter

An image filter that upscales images to twice their original size. As it uses an algorithm optimized for small or low-resolution images, it often produces better results than standard sampling algorithms on icons and pixel art.

In-place filtering: This class does not support in-place filtering (the source and destination images must be different). Moreover the destination must be of exactly double the width and height of the source.

Since:

3.4

Method Detail

getBounds2D

public java.awt.geom.Rectangle2D getBounds2D(java.awt.image.BufferedImage source)

Description copied from class: AbstractImageFilter

The base implementation returns the bounds of the image in image space; that is, the rectangle defined by 0, 0, source.getWidth(), source.getHeight().

Specified by:

getBounds2D in interface java.awt.image.BufferedImageOp

Overrides:

getBounds2D in class AbstractImageFilter

getPoint2D

public java.awt.geom.Point2D getPoint2D(java.awt.geom.Point2D sourcePoint,
                                        java.awt.geom.Point2D destPoint)

Description copied from class: AbstractImageFilter

The base implementation returns a copy of the original point.

Specified by:

getPoint2D in interface java.awt.image.BufferedImageOp

Overrides:

getPoint2D in class AbstractImageFilter

createCompatibleDestImage

public java.awt.image.BufferedImage createCompatibleDestImage(java.awt.image.BufferedImage source,
                                                              java.awt.image.ColorModel destinationColorModel)

Description copied from class: AbstractImageFilter

Specified by:

createCompatibleDestImage in interface java.awt.image.BufferedImageOp

Overrides:

createCompatibleDestImage in class AbstractImageFilter

filter

public java.awt.image.BufferedImage filter(java.awt.image.BufferedImage src,
                                           java.awt.image.BufferedImage dest)
