package boofcv.struct.image;
/**
* <p>
* 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.
* </p>
*
* <p>
* 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.
* </p>
*
* <p>
* 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.
