Overloads

ExtractPixelSection(Byte[], Int32, Int32, Int32Rect)	This method will extract a section from a 32bit or 24bit pixel buffer upconverting to 32bit opaque if necessary. Special colors Green-1 and Magenta will be translated into transparent pixels, all transparent pixels will then be made black.
ExtractPixelSection(Byte[], Int32, Int32, Int32Rect, Color[])	This method will extract a section from a 32bit or 24bit pixel buffer upconverting to 32bit opaque if necessary. Colors matching one of the transparent colors will be translated into transparent pixels, all transparent pixels will then be made black.
