1. An apparatus for line drawing, which uses a plurality of pixels to display a line, comprising:

  • a first parameter generating module, which generates a first parameter according to a slope of the line;

    a second parameter generating module, which generates a second parameter according to a distance between one of the pixels and the line in axial directions;

    a storage module, which stores an index table, wherein the index table records at least a blending factor and correlations between the first parameter, second parameter, and blending factor;

    a retrieving module, which searches the blending factor from the index table according to the first parameter and second parameter; and

    a calculating module, which determines a color of the pixel according to the blending factor.
