HP L 5 manual Select Palette Command, ?&p#S

Management by ID allows applications to tag data, have multiple raster configurations, and have palettes for different color spaces—all without reconfiguring the active palette. For example, one palette can be created for PCL text, one for HP-GL/2 primitives, one for simple raster, and one for 24-bit raster. The application can then switch between palettes according to what is being sent to the printer.

Selecting a new active palette changes the PCL graphics state. Besides color entries, a palette also contains the graphics state at the time the bitmap representation of the palette colors was created. This guarantees color reproduction integrity by insuring that the same color specification triplet always produces the same bitmap representation.

As described below, the Select Palette (?&p#S), Palette Control

(?&p#C), and Palette Control ID (?&p#I) commands implement the three basic operations of management by ID.

•Selection of the active palette

•Deletion of palettes

•Copying of palettes

Select Palette Command

The Select Palette command selects a new active palette by specifying an ID number. The previously active palette is unchanged.

?&p#S

#= Palette ID number

Default	=	0
Range	=	0 to 32767 (command is ignored for out- of-range
		values)

This command activates the designated palette in the palette store. The command is ignored if the specified ID matches the active palette's ID, or if no palette with that ID exists. The designated ID is saved as the palette select ID in the current modified print environment.
