A filter for processing Raster datasets.
RasterFilter is the base class for all raster filters. A filter
applies a transformation to a source raster either by modifying
that raster directly, or returning a new instance of that raster
that has the filter applied to it. To apply a filter to a raster,
use the Apply or
Apply In
Place methods. Common filters include color transformations,
like Brightness
Filter and Gamma
Correction Filter, and Convolution
Filter based filters like Sharpen
Filter and Edge Detect
Filter.
