Description The zimg program generates png images out of almost arbitrary formatted 2-D data. If no input files are given, zimg reads from stdin. If ascii data is read the first lines are parsed for zimg modelines until the first data point is read. In almost all cases you'll need to specify at least a few command line options to tell zimg something about the input format and specify the output style. Some switches can be defined more than once and are position dependent .
Spaces separating the single-letter options from their parameters are optional.
Quite a lot of options are not available if the gd driver was disabled at compile time. This option is used when reading unformatted ascii data. Each line will be truncated at pattern . This options might be used repeatedly to specify more than one comment pattern. This option was not really tested and might be still buggy.
