Method Detail

getMask

public final int getMask(int index)

getMasks

public final int[] getMasks()

createCompatibleSampleModel

public SampleModel createCompatibleSampleModel(int w,
                                               int h)

Overrides:

createCompatibleSampleModel in class ColorModel

isCompatibleSampleModel

public boolean isCompatibleSampleModel(SampleModel sm)

Overrides:

isCompatibleSampleModel in class ColorModel

getAlphaRaster

public WritableRaster getAlphaRaster(WritableRaster raster)

Description copied from class: ColorModel

Subclasses must override this method if it is possible for the color model to have an alpha channel.

Overrides:

getAlphaRaster in class ColorModel

Returns:

null, as per JDK 1.3 doc. Subclasses will only return null if no alpha raster exists.

equals

public boolean equals(Object obj)

Description copied from class: Object

equals compares this object to another object.

Equals must be symmetric (a.equals(b) == b.equals(a)), reflexive (a.equals(a)==true) and transitive (a.equals(b) && b.equals(c) IMPLIES (a.equals(c))) and not change over time (a.equals(b) == a.equals(b)). a.equals(null) should always return false.

If a.equals(b) is true for two objects a and b, then a.hashCode()==b.hashCode() must hold.

The default implementation of equals returns this==other.

Overrides:

equals in class ColorModel

Parameters:

obj - the other object.

Returns:

if this and other are considered equal.
