arguments
-version print version information
Use any setting or operator as an output-option. Only a
limited number of setting are input-option. They include:
-antialias, -caption, -density, -define, -encoding, -font,
-pointsize, -size, and -texture as well as any of the mis-
cellaneous options.
By default, the image format of `file' is determined by its
magic number. To specify a particular image format, precede
the filename with an image format name and a colon (i.e.
ps:image) or specify the image type as the filename suffix
(i.e. image.ps). Specify 'file' as '-' for standard input
or output.
