HP L 5 manual Saving the Palette, Push/Pop Palette Command, ? *p#P

Saving the Palette

The current palette is destroyed when a new palette is created. The Push/Pop Palette command (?*p#P) can save (push) the current palette and then restore (pop) it.

Push/Pop Palette Command

This command pushes or pops the palette from the palette stack.

?*p#P
# = 0	-	Push (save) palette
1	-	Pop (restore) palette
Default	=	0
Range	=	0, 1 (invalid values are ignored)

A value of 0 (?*p0P) pushes a copy of the active palette onto the palette stack. When a palette is pushed, the active palette is not affected.

A value of 1 (?*p1P) pops the most recently pushed palette and destroys the active palette; the popped palette becomes the active palette. As with any stack, the last item pushed is the first item popped.

Pushing a palette saves the following parameters:

•Color definitions for each palette entry

•Pen widths (for HP-GL/2 use)

•Color space specification

•Number of bits per index

•Pixel encoding mode

•Number of bits per primary

•Color treatment

•Render algorithm
