public interface ILcdTile
Important notice: the package com.luciad.imaging presents a new API for the modeling of raster data. For new projects, it is recommended to use this API instead of ILcdRaster et al. This interface represents a regular matrix of integer values.

A tile is defined over a rectangle in a discrete coordinate system. The tile width, height, and coordinates are expressed as integers. The x and y axes are pointing to the right and down, respectively. Tile coordinates (0, 0) correspond to the upper-left corner of the tile.

The interface defines methods for retrieving the tile contents as images or as individual values.

A tile can optionally have a color model that specifies how the tile values can be displayed.
