HP PCL Graphics Commands 9-19

source transparency mode
Source transparency mode is the transparency or opaqueness of the source
image’s white pixels (the “0” bits) as they are applied to the destination image.
Setting the source transparency mode to 1 (opaque) applies the source image
white pixels to the destination image; with a setting of 0 (transparent), these
pixels have no effect on the destination.

pattern transparency mode
Pattern transparency mode is the transparency or opaqueness of the white pixels
in the pattern. When set to 0 (transparent), these pixels have no effect on the
destination; when set to 1 (opaque), they are applied through the black pixels of
the source pattern to the destination.

This command sets the source image’s transparency mode to transparent or opaque. A
transparency mode of “0” (transparent) means that the white regions of the source image
are not copied onto the destination. A transparency mode of “1” (opaque) means that the
white pixels in the source image are applied directly onto the destination.
