Rgbimage

The rgbimage style is intended for plotting 2D images and is similar in concept to image. See image (p. ) for details. The difference is that 5D data (x,y,r,g,b) for plot and 6D data (x,y,z,r,g,b) for splot describe the coordinates and color components of an image. Currently, color images are only possible when the sampling grid is rectangular and oriented with the view plane. General orientations must be done with filled polygons which only support palette table lookup, not primary colors.
