Package net.sourceforge.jiu.data Description

Provides classes to store images and data directly related to them.

Package Specification

The base interface for image data in JIU is PixelImage. The concept of a pixel image includes the following properties:

The image data is arranged as a rectangular grid of pixels. The image has a fixed number of columns (width) and rows (height). Width and height can be queried using the method getWidth and getHeight.
Each pixel is made up of one or more samples. The exact number of samples per pixel equals the number of channels. Nothing is said about the nature of the samples (e. g., their type) and no ways to access samples or pixels are provided in the PixelImage interface.
A class implementing PixelImage must provide the createCompatibleImage method which gets a width and a height value as parameters and must return a new object of the same class with that pixel resolution.
Helper methods in PixelImage include ways to get a textual description of the type and the number of bytes allocated for a specific object implementing PixelImage.

The interface IntegerImage extends the PixelImage interface. All sample values belonging to an object of a class implementing IntegerImage are supposed to be integer values that can be stored in an int value (a signed 32 bit value).
