Abstract
The invention method and system provides rotation of an image on a display screen. A graphics library translates on-screen coordinates from a base viewing mode to a desired alternate viewing mode. The translated coordinated are rendered directly to the display screen.
Claims16
A method of rotating an image on a display screen comprising:
- initializing a base mode of the display screen;
- choosing one of a plurality of alternate modes for displaying a subject image;
- using rotation functions of a graphics library, translating in a display memory on-screen coordinates from the base mode to the chosen alternate mode, the translating being in real time;
- and
- using the translated coordinates, employing at least object drawing functions of the graphics library, rendering the image according to the chosen alternate mode, said rendering being directly to the display screen from the display memory, wherein only the display memory is used for the functions of the graphics library.

A computer system for rotating an image on a display screen comprising:
- an initialization module for initializing a base mode of the display screen;
- a switching mechanism for choosing one of a plurality of alternate modes for displaying a subject image;
- a translation module for using rotations functions of a graphics library for translating in a display memory on-screen coordinates from the base mode to the chosen alternate mode, the translating being in real time;
- and
- a rendering module for using the translated coordinates, employing at least object drawing functions of the graphics library for rendering the image according to the chosen alternate mode, said rendering being directly to the display screen from the display memory, wherein only the display memory is used for the functions of the graphics library.
