DESCRIPTION

14       sines creates an one band unsigned char image of the a sine waveform in
15       two dimensions.  The sizes of the created image  are  xsize  by  ysize.
16       The  number  of  horizontal and vertical spatial frequencies are deter‐
17       mined by the variables horfreq and verfreq respectively.
18
19       squares creates an one band unsigned cahr image by thresholding a  sine
20       waveform.
