Palette Control
The Palette Control command provides a mechanism for making and
deleting palettes.
?&p#C
• A value of 0 deletes all palettes except those on the palette
stack. The active palette is replaced by the default black and
white palette (ID 0). The palette control ID is not used.
• A value of 1 clears the palette stack. The active palette is
unaffected, and the palette control ID is not used.
• A value of 2 deletes the palette with the specified palette
control ID if it exists; otherwise the command is ignored. For
example, to delete palette 53, send
?&p53i2C. If the active
palette's ID is specified the active palette is replaced by the
default black and white palette. This option does not change
the palette control ID value.
Note When the active palette is replaced by the default black and white
palette, the graphics state associated with the previous palette is also
replaced.
• A value of 6 creates a copy of the active palette. The copy
receives the ID specified by the last Palette Control ID
command. For example, to copy the active palette to a palette
with an ID of 14, send
?&p14i6C. The copied palette
overwrites any palette that already has an ID equal to the
palette control ID. The copied palette does not become the
active palette. The command is ignored if a palette is to be
copied to its own ID.
