  • Method Summary

    Modifier and Type
    Method
    Description
    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 Details

    • 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
