A raster background filter.
The BackgroundFilter is a pixel filter that trims left and right pixels with a given background value (by setting them to NoData), until the first non background pixel is encountered. This pixel filter works the best when the pixel block spans the entire scan line. It can be used to implement the background functionality in ArcSDE command line command SDERASTER.
To filter multiple background values, multiple filters can be stacked into a PixelFilterCollection.
