摘要: A visual acuity tester based on a personal computer is provided that capable of displaying test characters at varying sizes monitor. The antialiases the to overcome effects staircase distortion. Preferably, performs unweighted area sampling antialiasing. also centers relative pixel array monitor improve appearance characters. can be centered either center or corner (a coordinate). Test in one dimension and coordinate other dimension.
