Abstract

A method for defining the size of an object displayed on a computer screen, the computer screen having a matrix of sensor points, said method comprising the steps of displaying an object on a computer screen, defining at least one screen area having a reference point associated therewith, reading an input from a sensor point in a screen area, calculating a vector between the read input and the reference point of that screen area, and defining the size of the object based on the vector.

Claims

1. A method for defining the size of an object displayed on a computer screen, the computer screen having a matrix of sensor points, said method comprising the steps of:

displaying an object on a computer screen,

defining at least one screen area having a reference point associated therewith,

reading an input from a sensor point in a screen area,

calculating a vector between the read input and the reference point of that screen area, and

defining the size of the object based on the vector.

2. A method according to claim 1, wherein the computer screen is a touch screen and wherein the sensor points correspond to sensor points of the touch screen.

3. A method according to claim 1, wherein the reference point is a corner point of the screen.

4. A method according to claim 1, wherein the reference point is a point defined by the shape of the object.

5. A method according to claim 1, wherein the reference point is visualized on the screen.

6. A method according to claim 1, wherein the border of the screen area is defined by a raster image.

7. A method according to claim 1, wherein the border of the screen area is defined by a vector graphic object.

8. A method according to claim 1, wherein the border of the screen area is defined by a text field.

9. A method according to claim 1, wherein the object is a raster image.

10. A method according to claim 1, wherein the object is a vector graphic object.

11. A method according to claim 1, wherein the object is a text field.

12. A method according to claim 1, wherein the object is a frame for framing an image.

13. A method according to claim 1, wherein the vector determines a direction of resizing and a degree of resizing.

14. A method according to claim 1, wherein the direction of the vector is determined as the direction from the reference point to the sensor point from which an input has been read.

15. A method according to claim 1, wherein the object is resized by moving a predetermined part of the object from a first position to a second position, the vector connecting the first and the second positions.

16. A method according to claim 1, wherein the object is resized by moving a predetermined part of the object from a first position to a second position, a predetermined fragment of the vector connecting the first and the second positions.

17. A method according to claim 1, wherein the reading of an input from a sensor point in a screen area is repeated periodically.

18. A method according to claim 17, wherein the object, upon reading an input from a sensor point, is periodically resized by moving a predetermined part of the object from a first position to a second position, a predetermined fragment of the vector connecting the first and the second positions.

19. A method according to claim 1, wherein the definition of the size is combined with a drag object operation wherein the length of the vector and accordingly the size of the object is fixed while the object is moved.

20. A system for presentation of images, the system comprising a screen with a plurality of sensitive points and a processor for processing input from the sensitive points, the processor being adapted to process the input in accordance with the method for defining the size of the object according to claim 1.

21. A scanner for scanning images and comprising an operator interface with a screen and a processor, the processor being adapted to process input from the screen in accordance with the method for defining the size of the object according to claim 1.
