HP L 5 manual Source Transparency Mode Command, ? * v # N, Default

Source Transparency Mode Command

The Select Source Transparency Mode command sets the source image's transparency mode to transparent or opaque. This command determines whether the source's white pixels are applied to the destination.

?* v # N

# = 0	-	Transparent
1	-	Opaque
Default	=	0

	Range = 0, 1 (other values cause the command to be ignored)
	With a transparency mode of “0” (transparent), the white regions of
	the source image are not copied onto the destination. With a
	transparency mode of “1” (opaque), the white pixels in the source are
	applied directly onto the destination. White pixels are unaffected by
	pattern or foreground color; they are either white or transparent.
Note	For RGB color images, “white” pixels are those for which all color
	primaries are 255. For CMY color images, “white” pixels are those for
	which all color primaries are 0.
	White dots introduced in the dithering process are not subject to
	transparency modes.
	Refer to the preceding definitions and the discussion of Figure 5-3 for
	an explanation of the effects of source transparency.
