Abstract

A method and apparatus for providing graphic editors are disclosed. The apparatus includes a coordinate system setting unit, a windowing unit, a window definition unit, a window manager unit, a graphics object setting unit, and an event processing unit. The coordinate system setting unit sets a coordinate system as a real-world coordinate system. The windowing unit converts figures within a data structure into coordinates of a window coordinate system. The window definition unit defines a pair of one view region and a real physical window as one virtual canvas window. The window manager unit converts coordinates of the virtual canvas window into window coordinates. The graphics object setting unit sets graphics objects corresponding to the data structure of the figures. The event processing unit provides a graphic editor so that an event is processed using the graphics characteristics and the graphics objects.

Claims

1. A method of providing graphic editors, comprising:

setting, by an apparatus for providing graphic editors, a coordinate system, which will be applied to a task of outputting one or more figures within a data structure onto a screen, as a real-world coordinate system;

converting the figures within the data structure, stored in the real-world coordinate system, into coordinates of a window coordinate system;

defining a pair of one view region in the real-world coordinate system and a real physical window in which the one view region is output onto a screen, as a single virtual canvas window;

converting the virtual canvas window into window coordinates on the screen using the window coordinate system, and designating graphics characteristics for an output task;

setting graphics objects corresponding to the data structure of the figures defined to draw a graphics figure in the virtual canvas window; and

providing a graphic editor so that an event corresponding to input data received from a user is processed using the graphics characteristics and the graphics objects.

2. The method of claim 1, wherein setting the coordinate system as the real-world coordinate system comprises setting the coordinate system as an X-Y rectangular coordinate system.

3. The method of claim 1, wherein converting the figures within the data structure into the coordinates of the window coordinate system comprises performing windowing adapted to execute tasks including a screen enlargement command, a screen reduction command, and a screen movement command.

4. The method of claim 1, wherein defining the virtual canvas window comprises defining a virtual window in which the figures are drawn using real real-world coordinates of the figures stored in the data structure without conversion of coordinates.

5. The method of claim 1, wherein designating the graphics characteristics comprises designating graphics characteristics corresponding to the figures so that the figures are finally drawn in a window on a screen using output-related functions provided by a Window System.

6. The method of claim 5, wherein a command function of the output-related functions corresponds to a function required to convert the coordinates of the virtual canvas window into the window coordinates on the screen.

7. An apparatus for providing graphic editors, comprising:

a coordinate system setting unit configured to set a coordinate system, which will be applied to the task of outputting figures within a data structure to a screen, as a real-world coordinate system;

a windowing unit configured to convert the figures within the data structure, stored in the real-world coordinate system, into coordinates of a window coordinate system;

a window definition unit configured to define a pair of one view region in the real-world coordinate system and a real physical window in which the one view region is output onto a screen as one virtual canvas window;

a window manager unit configured to convert coordinates of the virtual canvas window into window coordinates on the screen using the window coordinate system and to designate graphics characteristics for an output task;

a graphics object setting unit configured to set graphics objects corresponding to the data structure of the figures defined to draw a graphics figure in the virtual canvas window; and

an event processing unit configured to provide a graphic editor so that an event corresponding to input data received from a user is processed using the graphics characteristics and the graphics objects.

8. The apparatus of claim 7, wherein the coordinates setting unit sets the coordinate system as an X-Y rectangular coordinate system corresponding to the real-world coordinate system.

9. The apparatus of claim 7, wherein the windowing unit converts the figures into coordinates of the window coordinate system through windowing adapted to execute tasks including a screen enlargement command, a screen reduction command, and a screen movement command.

10. The apparatus of claim 7, wherein the window definition unit defines a virtual window in which the figures are drawn using real-world coordinates of the figures stored in the data structure without conversion of coordinates.

11. The apparatus of claim 7, wherein the window manager unit designates graphics characteristics corresponding to the figures so that the figures are finally drawn in a window on a screen using output-related functions provided by a Window System.

12. The apparatus of claim 11, wherein a command function of the output-related functions corresponds to a function required to convert the coordinates of the virtual canvas window into the window coordinates on the screen.
