Abstract

A method and apparatus for displaying data on a computer display system. More specifically, with this invention location information of data from an application program is converted to location information for displaying data within a number of contours on a display device. With this invention display data for a logical display area on a first contour is converted to display data for a plurality of contours, where each of the later contours is a logical section of the former contour. More importantly, this conversion is transparent to the application program. The second display data is then displayed on the display device of the computer system.

Claims

1. In a computer system having a processor and an electronic display device, a method of displaying data on said device, said method comprising:

a. converting first location information for said data from an application program into second location information for said data, where said first location information is for a logical display area on a first contour and where said second location information is for a plurality of contours, each of said second contours being a logical section of said first contour, where said conversion is transparent to said application program; and

b. displaying said data on said display device at locations in said second contours in accordance with said second location information.

2. A method of displaying data as recited in claim 1, wherein said first location information comprises cartesian coordinates of points within said first contour and corresponding to where in said contour said data should be displayed.

3. A method as recited in claim 1, wherein said second location information comprises cartesian coordinates corresponding to where said data should be displayed in said second contours.

4. A method as recited in claim 1, wherein said first and said second contours are rectangles.

5. A method as recited in claim 1, wherein the vertical length of said first contour exceeds the vertical length of said display area or the horizontal length of said first contour exceeds the horizontal length of said display area.

6. A method as recited in claim 1, wherein said second plurality of contours is a set of adjoining congruent rectangles.

7. A computer system for displaying data, said system comprising:

a. an electronic display device;

b. means for converting first location information for said data from an application program into second location information for said data, where said first location information is for a logical display area on a first contour and where said second location information is for a a plurality of contours, each of said second contours being a logical section of said first contour, where said conversion is transparent to said application program; and

c. means for displaying said data on said display device at locations in said second contours in accordance with said second location information.
