Examples of org.geotools.coverage.io.RasterLayout

org.geotools.coverage.io.RasterLayout
A class describing the desired layout of an OpImage.
The RasterLayout class encapsulates three types of information about an image:
- The image bounds, comprising the min X and Y coordinates, image width, and image height;
- The tile grid layout, comprising the tile grid X and Y offsets, the tile width, and the tile height; and
Methods that modify the state of an RasterLayout return a reference to 'this' following the change. This allows multiple modifications to be made in a single expression. This provides a way of modifying an RasterLayout within a superclass constructor call.
