CPAL — Control PALette
Format
CPAL mode[, palette-id];
Parameters
mode:
palette control mode:
A = Delete all palettes
S = Delete all stacked palettes
D = Delete the palette having the specified ID
C = Copy the active palette to the specified ID
palette-id:
number from 0 to 32767 (Default is 0)
Function
The CPAL command controls the palette identified by palette-id in the way described by
the control mode. If palette-id is not specified, the command is applied to palette of ID 0.
No check is made whether the palette ID number given already exists for another palette.
The palette ID number is reset to 0 by RES command.
Mode A deletes all existing palettes and brings the default palette back to the default state
(ID 0). Note that non-active palettes are not deleted. Also, palette-id is not used when
mode is A.
Mode S deletes all palettes that are not active. The active palette is not affected. Also,
any ID specified by palette-id is not used.
Mode D deletes the palette having the ID specified by palette-id regardless of being
active or inactive. If the palette deleted was active, then the current palette will be a
monochrome palette having the same ID as that of the deleted palette.
Mode C copies the currently active palette to a new palette with the new ID specified by
palette-id. If the palette having the same ID already exists, that palette is overwritten.
Deleting or copying a color palette does not affect color print quality on output pages.
