const int Derm.Raster.LayerImage< T >.LAYER_COUNT = 3 [protected]

Number of layers composing this LayerImage.

template<T >

LayerImage pixel data.

template<T >

int Derm.Raster.LayerImage< T >.mLayerXSamples = 1 [protected]

Property Documentation

template<T >

override Pixel.Type Derm.Raster.LayerImage< T >.PixelFormat [get]

Image pixel format.

Returns:

It returns a Pixel.Type specifying the image color resolution.

This property shall be only an indicative value about the image color resolution, to allow the best memory management due color precision. Actually this property shall not be used to determine image layering (i.e. YUV formats imply three layers).

Reimplemented from Derm.Raster.Image.

template<T >

override IColor Derm.Raster.LayerImage< T >.this[int layer, int x, int y] [get, set]

Pixel data accessor.

Parameters:

	x	A System.Int32 indicating the horizontal coordinate of the pixel. The left corners has the coordinate 0.
	y	A System.Int32 indicating the vertical coordinate of the pixel. The bottom corners has the coordinate 0.

Reimplemented from Derm.Raster.Image.

template<T >

int Derm.Raster.LayerImage< T >.XSampling [get]

Chrominance horizontal sampling.

template<T >

int Derm.Raster.LayerImage< T >.YSampling [get]

Chrominance vertical sampling.
