NAME
sines, squares - creates a spatial sine or square wave form
SYNOPSIS
sines image xsize ysize horfreq verfreq
squares image xsize ysize horfreq verfreq
DESCRIPTION
sines creates an one band unsigned char image of the a sine waveform in
two dimensions. The sizes of the created image are xsize by ysize.
The number of horizontal and vertical spatial frequencies are deter-
mined by the variables horfreq and verfreq respectively.
squares creates an one band unsigned cahr image by thresholding a sine
waveform.
