Writes an image to an X-bitmap (XBM) file.

file — A scalar string giving the filename of the XBM image.

image — The variable containing the input image.

None.

Since XBM is a monochrome (2-color) format, the input image is forced into 2 colors, if it is not already. Any extra colors are re-mapped using the median point between the minimum and maximum color values; anything less than the median value is converted to 0 (background), while the median and higher values are converted to 1 (black).

image = BYTE(DIST(100))

; Write a 2D byte array to an XBM file.
