<p>Disclosed is a line-draw method and apparatus that draws lines at fast speeds. Lines are drawn a pixel at a time and a number of algorithms are employed to determine the pixels to be drawn. The line-draw method determined is a function of line length, typical length categories are short (49), medium (199), and long (248). For short lines (49), a table look-up method is employed (111). For longer length lines (199, 248), a multi-pixel segment (burst method) is employed (247 603). Burst methods are line-draw methods which draw lines using a plurality of multi-pixel segments to draw the lines where each segment is characterized as having a number (U) of unconditional pixels which are always drawn and an actual number (A) of conditional pixels which are drawn. The actual number (A) is any number up to a maximum number (C) of conditional pixels which can be drawn.</p> |
