Graphics
save tables for McIDAS-X, where * is a user-defined file name.
These binary files
contain a table of the red, green and blue color intensities (0 to 255) for
the graphics levels on a McIDAS-X workstation. The table is of variable length,
depending on the number of graphics levels allocated by the McIDAS-X session
that generated the file. Use the GU application
to create a McIDAS-X graphics save table.
For graphics
