net.sourceforge.jiu.data.PixelImage
The base interface for all image data types in JIU. These image data classes and interfaces share the following properties:
- They are made up of a rectangular grid of pixels (color dots) and have a fixed width (horizontal number of pixels) and height (vertical number of pixels).
- Coordinates to access pixels in the image are defined to run from 0 to WIDTH - 1 in horizontal direction from left to right and in vertical direction from 0 to HEIGHT - 1 (from top to bottom).
- They have one or more channels. A pixel at a given position is made up of the samples (primitive values) of all the channels at that position. A pixel can thus be considered a vector (in the mathematical sense) of one or more samples. Each channel has the same width and height.
