rgbcol	nx3 matrix of RGB values in [0,1]. Colors of the background of patches.
rgbhatch	nx3 matrix of RGB values in [0,1]. Colors of hatchings.
side	side of each image patch, in pixels.

rgbpatch object, structured as follows :

rchannel	n x squared(side) matrix, containing R values in [0,1] for the n patches. Each line, ie patch, is intended to be restored column-wise for drawing.
gchannel	same for G values.
