The Map Wrapper classes are light wrappers for Frame Objects maps (from metadata classes). These wrapper classes provide small data-focused objects for simplified data access to frame objects generated by the generator nodes.

Map Wrapper classes are defined for the following generator types:

Generator Type	Map Wrapper Class	Operation Data Type
xn::DepthMetaData	xn::DepthMap	XnDepthPixel
xn::ImageMetaData	xn::ImageMap	XnUInt8
xn::ImageMetaData	xn::RGB24Map	XnRGB24Pixel
xn::ImageMetaData	xn::Grayscale16Map	XnGrayscale16Pixel
xn::ImageMetaData	xn::Grayscale8Map	XnGrayscale8Pixel
xn::IRMetaData	xn::IRMap	XnIRPixel
xn::SceneMetaData	xn::LabelMap	XnLabel
