ABSTRACT:
In a pixel based color display system, aliasing is minimized by controlling the colors in pixels, bridging boundaries of objects of the image to be blends of the colors on each side of the boundary. Blends are controlled in accordance with pixel words containing mix values. Provision is made for drawing lines one pixel line with aliasing minimized in the boundaries of the lines wherein the same mix value controls the blend in adjacent pixels bridging the leading and trailing edge of a diagonal line.
