Abstract

A method of providing a display (11) for a graphical user interface in which a user may define a selected point (13) of a subject image (12) is disclosed together with a computer program, a computer-readable storage medium (62) and apparatus for the same (61). The method comprising the steps of (i) displaying the subject image (12); (ii) displaying an enlargement of the subject image (12′) in response to a user selecting a point (21) on the subject image and displaying on that enlargement that point selected by the user; and (iii) returning a point (40) previously selected by the user as displayed on an enlargement (12″) of the subject image as a first co-ordinate parameter. Additionally, the method may further comprise the step of (iv) displaying a reduction of a previous enlargement of the subject image, wherein steps (iii) and (iv) are done in response to a single user input.

Claims

1. A method of providing a display for a graphical user interface in which a user may define a selected point on a subject image, the method comprising the steps of:

(i) displaying the subject image;

(ii) displaying an enlargement of the subject image in response to a user selecting a point on the subject image and displaying on that enlargement that point selected by the user; and

(iii) returning a point previously selected by the user as displayed on an enlargement of the subject image as a first co-ordinate parameter.

2. A method according to claim 1 further comprising the step of (iv) displaying a reduction of a previous enlargement of the subject image, wherein steps (iii) and (iv) are done in response to a single user input.

3. A method according to claim 1 further comprising the step of displaying a further enlargement of a previous enlargement of the subject image in response to a user selecting a point on that previous enlargement.

4. A method according to claim 1 wherein an enlargement of the subject image displayed in response to a user selecting a point on that subject image is displayed centered about that point selected by the user.

5. A method according to claim 1 wherein a reduction of a previous enlargement of the subject image is displayed in the same scale as the subject image prior to enlargement.

6. A method according to claim 1 further comprising the step of returning a further point selected by the user as a second co-ordinate parameter.

7. A method according to claim 6 further comprising the step of performing a calculation to determine the distance between the first and second co-ordinate parameters.

8. A computer program comprising instructions for performing a method according to claim 1.

9. A computer-readable storage medium having recorded thereon data representing instructions for performing a method according to claim 1.

10. Apparatus having a display, a processor and a user input device wherein the processor is programmed to perform a method according to claim 1.
