In addition to the GKS-0A functions, you may
wish to use the segmentation functions provided in GKS at level 2A
for storing instructions in segments. You may use those segments in
several ways: by inserting them into subsequent pictures; by
scaling the segments; and by specifying
whether a segment is visible or not, or whether it is highlighted
or not. The NCAR GKS package has been augmented by implementing
a select few GKS level 2A segmentation functions to create, insert,
and close segments. We recommend that you use the utility package
Gflash to access this functionality.
For details on Gflash, see
NCAR Graphics Fundamentals, UNIX Version and the SCD UserDoc
GFLASH - A Graphics Instruction and Manipulation Package.
If you have access to a higher-level GKS package than the NCAR package,
then you will probably want to use the segmentation functions of
that package directly.
