Class ImageInteger<T extends ImageInteger>

java.lang.Object

boofcv.struct.image.ImageBase<T>

boofcv.struct.image.ImageSingleBand<T>

boofcv.struct.image.ImageInteger<T>

All Implemented Interfaces:

Serializable, Cloneable

Direct Known Subclasses:

ImageInt16, ImageInt8, ImageSInt32

public abstract class ImageInteger<T extends ImageInteger>
extends ImageSingleBand<T>

Base class for all integer images. An integer image can either be signed or unsigned. Since all integers in Java are signed (which is really f*ing annoying) a boolean variable is used to differentiate these image types.

DESIGN NOTE: No performance or generality is lost by using the 'int' type for setters and getters. At a low level the JavaVM converts all integer types into an int when not in an array.

DESIGN NOTE: Java does not support unsigned data. If an image is unsigned this is only directly enforced by the get() function. When directly accessing the data array the data's unsigned nature must be enforced manually using the bitwise and operator.
