nsppkern plot



nsppkern -- draw metacode on an NSPP interfaced plotter device


nsppkern input


The list of input metacode files.
device = "nsppdefault"
The NSPP interfaced plotting device output is to be directed to.
generic = no
The remaining parameters are ignored when generic = yes.
debug = no
If debug = yes, the graphics instructions are decoded and printed during processing.
verbose = no
If verbose = yes, the elements of polylines, cell arrays, etc. will be printed in debug mode.
gkiunits = no
By default, coordinates are printed in NDC rather than GKI units.


Task nsppkern translates metacode and draws it on a plotting device. Input is GKI metacode, which can be read from one or more binary files or redirected from the standard input.

If debug is set to yes, the plotting instructions are printed in readable form during processing. If verbose = yes, elements of polyline and cell array calls are printed in addition to the default debug output. Coordinates can be printed in either GKI (0 - 32767) or NDC (0.0 - 1.0) units.


1. Extract the fourth frame from metacode file "" and plot it.

cl> gkiextract 4 | nsppkern

2. Plot metacode frame "contour.demo" in debug mode, so the plotting instructions can be read as they are processed.

cl> nsppkern contour.demo debug+
