PLOT3-PLOT3(1)

plot3-plot3 - convert an extended to a simple UnixPlot file

plot3-plot3 [-v] [-S] < unix_plot > unix_plot

UnixPlot is a simple machine and device independent plotting file format found on both System V and BSD Unix systems. BRL has extended that format to include color, three dimensional plotting, machine independent floating point coordinates, and a flush command for interactive output.

plot3-plot3 converts an extended UnixPlot file to the simpler format for use by older, and non-extended, programs. It drops color and flush commands, strips the Z coordinate of 3D commands, and converts floating point coordinates to integer. By default, conversion to integer is done by simple truncation. If the -S option is given, the "space" command in the plot file is used to center and scale the plot to the full 16 bit signed integer plotting space (-32767 to +32767). This is particularly useful for converting floating point files. The -v verbose option causes each plot command to be described as it is being converted.

A warning message is given if the input plot file did not contain a space command since most older UnixPlot programs require them.
