static array<float>^ RollFilter(
	array<float>^ raw, 
	int width, 
	int height, 
	int radius
)

Parameters

raw: Type: System Single
raw image

width: Type: System Int32
image width

height: Type: System Int32
image height

radius: Type: System Int32
radius of moving window (full window size will be 2*radius+1)

Return Value

Type:

Single
processed image

Remarks

Allocates processed image, as well as row and column strip sums and calls the most general overload. Calling this version multiple times with large images will probably thrash the GC.
