FUNCTION c_pixflip(pixels, nvalues)
short pixels[]; long nvalues;
An array of short pixel values.
The number of pixels in the line.
The c_pixflip() routine is used to "horizontally" flip a line of pixel values. It is usually used to convert a line of pixels read from an ascending image, which run from east to west along the line, to north-up order, which run from west to east along the line.
c_pixflip() has no return value.
