Abstract:
1. A method of graphically previewing changes to hardware driver parameters in a graphical computing environment, said method comprising: forcing an executable graphics program module to load hardware driver parameter settings; drawing a first preview region using said executable graphics program module in a window on a display; receiving user input indicating changes to said hardware driver parameter settings from initial settings to changed settings; altering said hardware driver parameter settings to reflect said changed settings; creating a further instance of said executable graphics program module, and forcing said further instance of said executable graphics program module to load said hardware driver parameter settings as changed; drawing a second preview region in place of said first preview region without redrawing the remainder of said window, using said further instance of said executable graphics program module and said hardware driver parameter settings as changed, said second preview region reflective of said changed settings and thereby graphically previewing said changed settings in said second preview region in said window; altering said hardware driver parameter settings to said initial settings, after said drawing a second preview region, so that other applications are unaffected by said changed settings to said hardware driver parameter settings.
