public interface Filter

Represents a multi-pixel image filter kernel.

Method Summary

float	get(float x, float y) Get value of the filter at offset (x, y).
float	getSize() Width in pixels of the filter extents.

Method Detail

getSize

float getSize()

Width in pixels of the filter extents. The filter will be applied to the range of pixels within a box of +/- getSize() / 2 around the center of the pixel.

Returns:

width in pixels

get

float get(float x,
          float y)

Get value of the filter at offset (x, y). The filter should never be called with values beyond its extents but should return 0 in those cases anyway.

Parameters:

x - x offset in pixels

y - y offset in pixels

Returns:

value of the filter at the specified location
