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
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.
