Methods

  • Fill components with the number of all the components packed in plane p for the format info. A value of -1 in components indicates that no more components are packed in the plane.

    Parameters

    • plane: number

      a plane number

    Returns number

  • Extrapolate plane stride from the first stride of an image. This helper is useful to support legacy API were only one stride is supported.

    Parameters

    • plane: number

      a plane number

    • stride: number

      The fist plane stride

    Returns number

    The extrapolated stride for plane
