Definitions

  • Figure 6 illustrates image sampling performed in accordance with one exemplary embodiment of the present invention.
  • Figure 7A illustrates a color flat panel display screen implemented in accordance with the present invention.
  • Figure 9 illustrates a method of rendering text for display in accordance with one embodiment of the present invention.
  • FIG. 5 and the following discussion provide a brief, general description of an exemplary apparatus in which at least some aspects of the present invention may be implemented.
  • Various methods of the present invention will be described in the general context of computer-executable instructions, e.g., program modules, being executed by a computer device such as a personal computer.
  • Other aspects of the invention will be described in terms of physical hardware such as, e.g., display device components and display screens.
  • Fig. 7A illustrates a display device 600 implemented in accordance with an embodiment of the present invention.
  • the display device 600 is suitable for use in, e.g., portable computers or other systems where flat panel displays are desired.
  • the display device 600 may be implemented as an LCD display.
  • the display and control logic of the known computer 100 are replaced by the display device 600 and display control logic, e.g., routines, of the present invention to provide a portable computer with horizontal RGB striping and pixel sub-components which are used to represent different portions of an image.
  • While the display 7A may be desirable for certain graphics applications, the accurate representation of character stems, the relatively long thin vertical portions of characters, is far more important than the representation of serifs in generating high quality characters.
  • Vertical striping has the distinct advantage, when used according to the present invention, of allowing for stems which can be adjusted in width 1/3 of a pixel at a time.
  • using a display device such as the device 200 or 700 with a vertical striping arrangement in conjunction with the display methods of the present invention can provide higher quality text than the known horizontal striping arrangement which limits stem width adjustments to one-pixel increments.
  • the application routine 536 which may be, e.g., a word processor application, includes a text output sub-component 801.
  • the text output subcomponent 801 is responsible for outputting text information, as represented by arrow 813, to the operating system 535 for rendering on the display device 547.
  • the text information includes, e.g., information identifying the characters to be rendered, the font to be used during rendering, and the point size at which the characters are to be rendered.
  • the operating system 535 includes various components responsible for controlling the display of text on the display device 547. These components include display information 815, a display adapter 814, and a graphics display interface 802.
  • the display information 815 includes, e.g., information on scaling to be applied during rendering and/or foreground/background color information.
  • the display adapter receives bitmap images from the graphics display interface 802 and generates video signals which are supplied to video adapter 548 for optical presentation by the display 547.
  • the arrow 816 represents passing of the bitmap images from the graphics display interface 802 to the display adapter 814.
  • the graphics display interface 802 includes routines for processing graphics as well as text.
  • Element 804 is a type rasterizer used to process text.
  • the type rasterizer is responsible for processing the text information obtained from the application 536 and generating a bitmap representation therefrom.
  • the type rasterizer 804 includes character data 806 and rendering and rasterization routines 807.
  • the rendering and rasterization routines 807 include a scan conversion subroutine 812 and can also include a scaling sub-routine 808, a hinting sub-routine 810, and a color compensation subroutine 813.
