ABSTRACT:
Apparatus for processing data whereby a digital control signal is generated for effecting the presentation of a selected portion of a map image on a raster display. The data includes stored data words describing characteristics of line segments utilizable to construct the image. The line segments include line vectors representative of elongated features of the image and boundary vectors identifying boundaries between image areas of different brightness. Processing of the data is accomplished by means of two control loops. The first control loop performs selected macrosteps including arithmetic manipulations, on the data words to effect generation of the digital control signal. The second control loop effects selection of the macrosteps to be performed by the first loop and routes the data words within the generator in response to the instant data being processed by the generator. In accordance with an additional feature of the invention, data words are generated for defining intersections to be displayed adjacent each intersection of a line segment with a raster line where the line segment has a slope of less than a predetermined magnitude. These additional intersections prevent the stepped appearance of line segments intersecting raster lines at small angles.
