Constructor Detail

ColorImageComparator

public ColorImageComparator(ColorImageComparator.ColorMap map)

Creates a comparator with a color maps. Object created by this constructor behaves like StrictImageComparator. Object created works faster because it does not create intermediate images for another comparator.

Parameters:

map - Map applied to both left and right images during comparision.

ColorImageComparator

public ColorImageComparator(ColorImageComparator.ColorMap map,
                            ImageComparator subComparator)

Creates a comparator with map color mapping. Actual comparision perfomed by comparator parameter.

Parameters:

map - Map applied to both left and right images during comparision.

subComparator - comporator to perform a comparision of to images with mapped colors.

ColorImageComparator

public ColorImageComparator(ColorImageComparator.ColorMap leftMap,
                            ColorImageComparator.ColorMap rightMap)

Creates a comparator with two color maps. Object created by this constructor behaves like StrictImageComparator. Object created works faster because it does not create intermediate images for another comparator.

Parameters:

leftMap - Map applied to the left image during comparision.

rightMap - Map applied to the right image during comparision.

ColorImageComparator

public ColorImageComparator(ColorImageComparator.ColorMap leftMap,
                            ColorImageComparator.ColorMap rightMap,
                            ImageComparator subComparator)

Creates a comparator with two color maps. Actual comparision perfomed by comparator parameter.

Parameters:

leftMap - Map applied to the left image during comparision.

rightMap - Map applied to the right image during comparision.

subComparator - comporator to perform a comparision of to images with mapped colors.

Method Detail

compare

public boolean compare(java.awt.image.BufferedImage image1,
                       java.awt.image.BufferedImage image2)

Compares images by ImageComparator passed into constructor, or itself if no ImageComparator was passed, processing both images by ColorMap instance before comparision.

Specified by:

compare in interface ImageComparator

Overrides:

compare in class StrictImageComparator

Parameters:

image1 - an image to compare.

image2 - an image to compare.

Returns:

True if all the pixels match, false otherwise.

compareColors

protected final boolean compareColors(int rgb1,
                                      int rgb2)

Description copied from class: StrictImageComparator

Could be used to override the way of comparing colors.

Overrides:

compareColors in class StrictImageComparator

Parameters:

rgb1 - a color to compare.

rgb2 - a color to compare.

Returns:

true if colors are equal.
