mgl2png - Execute MathGL scripts to generate Portable Network Graphics (PNG) output
SYNOPSIS
mgl2png < scriptfile > [outputname] [parameters]
DESCRIPTION
mgl2png converts mathgl scripts into scalable vector graphics (PNG) files, to produce plots of specified functions or data. When called
with only the script file name, the program will create an output PNG file in the same directory as the input script, with a .png exten-
sion. Any file entitled "scriptfile.png" (where scriptfile is the name of the script being executed will be overwritten.

and can be used to influence execution.

png - Portable Network Graphics (PNG) format
DESCRIPTION
PNG (Portable Network Graphics) is an extensible file format for the lossless, portable, well-compressed storage of raster images. PNG pro-
vides a patent-free replacement for GIF and can also replace many common uses of TIFF. Indexed-color, grayscale, and truecolor images are
supported, plus an optional alpha channel. Sample depths range from 1 to 16 bits.
PNG is designed to work well in online viewing applications, such as the World Wide Web, so it is fully streamable with a progressive dis-
play option. PNG is robust, providing both full file integrity checking and fast, simple detection of common transmission errors. Also, PNG
can store gamma and chromaticity data for improved color matching on heterogeneous platforms.
