HP L 5 manual Saving the Palette

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

•Black and white references

•Number of bits per index

•Pixel encoding mode

•Number of bits per primary

•Gamma correction

•Viewing illuminant

•Color lookup tables

•Render algorithm

•Downloaded dither matrix
