Color triads on a raster display CS 248 - Introduction to Computer Graphics Autumn quarter, 2008 Additional slides for September 25 lecture

Triads and color mixing SMPTE color bars closeup on a Sony Trinitron monitor

Triads versus pixels integral pixel font integral pixel font (Sony Trinitron) integral pixel font (IBM LCD) antialiased font (Adobe Acrobat) subpixel font (Adobe Cooltype) integral pixel font Internet Explorer 5.5, Times Roman font Subpixel font rendering technology See also Microsoft Cleartype – used in Vista Mac also does this, ignoring MS’s patent, since others had it earlier than MS. MS has never tried to enforce this patent. As pixels become smaller, it’s less necessary If you rotate your monitor 90 degrees, it renders incorrectly! (Mac will revert to grayscale antialiasing) Adobe Cooltype Acrobat 5.0, with one of many possible parameter settings for Cooltype
