   ImGearRasterPage* page,
   int neighborhoodWidth,
   int neighborhoodHeight
)

public:
static void FilterWithMedian( 
   ImGearRasterPage^ page,
   int neighborhoodWidth,
   int neighborhoodHeight
)

Parameters

page: Image to filter.
neighborhoodWidth: Width of the square area.
neighborhoodHeight: Height of the square area.

Remarks

This method looks for an average color value inside the square area near the pixel and replaces the pixel with this value. Processes color channels only.
