Abstract

Methods, program products and systems for accepting user input selecting a parameter for a parametric curve, the parametric curve being displayed in a graph. A range of curves for the parametric curve is determined based on a range of values for the parameter. And the range of curves for the parameter is displayed in the graph of the curve.

Claims

1. A computer-implemented method, comprising:

accepting user input selecting a parameter for a parametric curve, the parametric curve being displayed in a graph;

determining a range of curves for the parametric curve based on a range of values for the parameter; and

displaying the range of curves for the parameter in the graph of the curve.

2. The method of claim 1, further comprising:

highlighting a control corresponding to the parameter.

3. The method of claim 1, where the user input is one of:

indication of a parameter control, indication of a region in the graph, or indication of a pixel in an image corresponding to a location on the curve.

4. The method of claim 1, further comprising:

accepting user input modifying a value of the parameter.

5. The method of claim 4 where the user input is one or more of:

a mouse gesture or a keystroke.

6. The method of claim 5 where:

an upward mouse gesture increases a value of the parameter and a downward mouse gesture decreases a value of the parameter.

7. The method of claim 4, further comprising:

determining a new curve based on the value of the parameter; and

displaying the new curve in the graph.

8. The method of claim 1 where:

the range of curves represents one or more areas about the curve in the graph in which the curve will lie based on different values of the parameter.

9. The method of claim 1 where:

the curve is a combination of cubic curves.

10. The method of claim 9 where:

the parameter controls a slope of the curve.

11. The method of claim 1 where:

the parameter does not correspond to a location along the graph of the curve.

12. The method of claim 1 where:

the curve determines tone for an image.

13. A computer-implemented method, comprising:

accepting first user input indicating a region in a displayed graph or indicating a displayed control corresponding to the region, the control being in a separate display area from the graph;

automatically highlighting the region and the control in response to the first user input; and

automatically adjusting a value associated with the control based on second user input.

14. The method of claim 13 where:

the second user input is a mouse gesture.

15. The method of claim 14 where:

an upward mouse gesture increases the value and a downward mouse gesture decreases the value.

16. The method of claim 13 where:

the second user input is incident on the displayed graph.

17. The method of claim 13 where:

the displayed graph is a histogram.

18. A computer program product, encoded on a computer-readable medium, operable to cause data processing apparatus to perform operations comprising:

accepting user input selecting a parameter for a parametric curve, the parametric curve being displayed in a graph;

determining a range of curves for the parametric curve based on a range of values for the parameter; and

displaying the range of curves for the parameter in the graph of the curve.

19. The program product of claim 18, further comprising the following operations:

highlighting a control corresponding to the parameter.

20. The program product of claim 18, where the user input is one of:

indication of a parameter control, indication of a region in the graph, or indication of a pixel in an image corresponding to a location on the curve.

21. The program product of claim 18, further comprising:

accepting user input modifying a value of the parameter.

22. The program product of claim 21 where the user input is one or more of:

a mouse gesture or a keystroke.

23. The program product of claim 22 where:

an upward mouse gesture increases a value of the parameter and a downward mouse gesture decreases a value of the parameter.

24. The program product of claim 21, further comprising:

determining a new curve based on the value of the parameter; and

displaying the new curve in the graph.

25. The program product of claim 18 where:

the range of curves represents one or more areas about the curve in the graph in which the curve will lie based on different values of the parameter.

26. The program product of claim 18 where:

the curve is a combination of cubic curves.

27. The program product of claim 26 where:

the parameter controls a slope of the curve.

28. The program product of claim 18 where:

the curve determines tone for an image.

29. A computer program product, encoded on a computer-readable medium, operable to cause data processing apparatus to perform operations comprising:

accepting first user input indicating a region in a displayed graph or indicating a displayed control corresponding to the region, the control being in a separate display area from the graph;

automatically highlighting the region and the control in response to the first user input; and

automatically adjusting a value associated with the control based on second user input.

30. The program product of claim 29 where:

the first user input is a mouse gesture.

31. The program product of claim 30 where:

an upward mouse gesture increases the value and a downward mouse gesture decreases the value.

32. The program product of claim 30 where:

the gesture input is incident on the displayed graph.

33. The program product of claim 29 where:

the displayed graph is a histogram.

34. A system comprising:

means for accepting user input selecting a parameter for a parametric curve, the parametric curve being displayed in a graph;

means for determining a range of curves for the parametric curve based on a range of values for the parameter; and

means for displaying the range of curves for the parameter in the graph of the curve.
