Abstract
Remoting sub-pixel defined text. Text is remoted at sub-pixel precision in a computing environment including a terminal server and a terminal client. At a terminal server text definitions are generated. The text definitions include character definitions defining character boundaries with colors so as to be able to define character boundaries using sub-pixel precision by defining colors at the boundaries so as to make use of sub-pixel color components of LCD pixels when the characters are rendered on an LCD screen. At the terminal server glyphs of individual characters are generated. The glyphs include the character definitions including definitions of colored character boundaries. At the terminal server, the glyphs are sent to a terminal client. At the terminal client, the glyphs are blended with background color information and rendered on an LCD screen.
