    Get the pixel value at (x, y, channelIdx).

    Get the pixel value at (x, y, channelIdx). Channels are indexed as follows:

    • If the image is RGB, 0 => blue, 1 => green, 2 => red.
    • If the image is RGB+alpha, 0 => blue, 1=> green, 2 => red, and 3 => alpha.
    • Other channel schemes are unsupported; the only reason this matters is that input converters (e.g. from BufferedImage to Image) need to handle channels consistently.

  20. def iter(): Iterator[CoordinateValue]

    Returns an iterator of coordinate values based on the "natural" order of a Vectorized image.

    Returns an iterator of coordinate values based on the "natural" order of a Vectorized image. That is, this returns a value of the form (x,y,channel,value) in order.

    This method is optimized to avoid unnecessary memory allocation and designed to approach the performance of an equivalent while loop over the image pixels for speeding up things like Aggregation over an image regardless of underlying image ordering.

    An important restriction is that the reference to the returned CoordinateValue should not be modified or saved by the caller.

    Returns a flat version of the image, represented as a single array. It is indexed as follows: The pixel value for (x, y, channelIdx) is at channelIdx + x*numChannels + y*numChannels*xDim.

    This implementation works for arbitrary image formats but it is inefficient.
