CONVERSION OF FILLED AREAS TO RUN LENGTH ENCODED VECTORS

A method and system for converting a filled shape to a run length encoded RLE vector is disclosed. The method includes creating a virtual pixel array (212) of pixel cells corresponding to a graphical array (208) of pixels (216) comprising the filled shape. The method includes determining a border (2...

Zusammenfassung:	A method and system for converting a filled shape to a run length encoded RLE vector is disclosed. The method includes creating a virtual pixel array (212) of pixel cells corresponding to a graphical array (208) of pixels (216) comprising the filled shape. The method includes determining a border (200) on the virtual pixel array corresponding to the filled shape, storing a pixel-type value within each pixel cell that corresponds to a border line element (222) within the pixel, and creating a shape RLE group corresponding to a line of pixels (216) aligned along a first axis of the virtual pixel array. Once created, the position and length of the shape RLE group is stored as an RLE vector. The method for clipping filled shapes is also disclosed, which includes converting a clipping region to a clip RLE group, then comparing the clip RLE group to the shape RLE group, forming a clipped image RLE vector.
