Abstract
A method and system are provided for positioning characters within an arbitrarily sized graphics window in order to maximize the distribution of unused space. The method and system are particularly adapted for the redistribution of characters produced during a terminal emulation session with another computing system. Characters produced during the emulated session are adjusted to completely fill the graphics window, regardless of its size. A fill justification procedure distributes characters in areas within the graphics window that would otherwise appear as gutters or margins. A character spacing unit maintains correct character image proportions in the graphics window while not rigidly adhering to a uniform alignment of character rows and columns. A linear distribution procedure allows the character image to fill the graphics window completely with a natural appearance.
