Synopsys Assigned Patent

ALEXANDRIA, Va., Dec. 30 -- Synopsys, Mountain View, Calif., has been
assigned a patent (8,085,279) developed by Grigor S. Avagyan, Yerevan,
Armenia, and Jeffrey T. Brubaker, Carrboro, N.C., for a "drawing an
image with transparent regions on top of another image without using
an alpha channel."

The abstract of the patent published by the U.S. Patent and Trademark
Office states: "An image display system draws a first image on top of
a second image. Pixels of the first image include one or more color
channels which encode color information, but do not include an alpha
channel which encodes transparency information. The system encodes
transparency information for the pixels in the first image using at
least one bit in at least one color channel of each pixel. The system
draws the first image on top of the second image using the
transparency information encoded in the color channels of the pixels
to obtain a combined image."

The patent application was filed on Oct. 30, 2009 (12/610,241). The
