Abstract

Selecting and formatting warped text is disclosed. Text effects such as an underline effect and/or a strikethrough effect may be transformed along with rectangular text to form a warped text element. In such a situation, the text effects are warped with the characters of the text. Also, warped text may be accurately selected or “hit.” The coordinates of a selection of warped text are inversely transformed to map the selection to the rectangular text. The inverse transform provides an accurate manner to determine the scope and location of the selection. When the scope and location are determined, the graphical representation of the selection may be transformed to provide a user with an accurate representation of a warped selection.

Claims

1. A computer-implemented method for selecting and formatting warped text, the method comprising:

obtaining a text element having a linear orientation in a document of an application;

receiving a selection to warp the text element;

upon receiving the selection to warp the text element, applying a transform algorithm to the text element to cause a computer processor to transform the linear orientation into a warped orientation;

obtaining a text effect selection of the warped orientation of the text element;

applying an inverse transform algorithm to the text effect selection of the warped text element, wherein the inverse transform algorithm is an inverse algorithm of the transform algorithm;

determining a location of the text effect selection in relation to the text element having the linear orientation based on the application of the inverse transform algorithm; and

after determining the location of the text effect selection in relation to the text element having the linear orientation, applying the transform algorithm to a text effect related to the text effect selection to cause a computer processor to display the text effect at the determined location in the warped orientation of the text element.

2. The computer-implemented method of claim 1, wherein the text element includes at least one member of a group comprising:

a character, a letter, a number, a word, a symbol, a graph, and a picture.

3. The computer-implemented method of claim 1, wherein the text effect includes at least one member of a group comprising:

a highlight selection, an underline, and a strikethrough.

4. The computer-implemented method of claim 1, wherein the text effect selection relates to a cursor hit on the warped orientation.

5. The computer-implemented method of claim 4, wherein the text effect selection includes a cursor displayed rotated in accordance with the warped orientation.

6. The computer-implemented method of claim 1, wherein the text effect selection relates to a selection highlight block on the warped orientation.

7. The computer-implemented method of claim 6, wherein the selection highlight block is rotated in accordance with the warped orientation.

8. A computer-readable storage medium having computer executable instructions for selecting and formatting warped text, the instructions comprising:

obtaining a text element having a linear orientation;

receiving a selection to warp the text element;

upon receiving the selection to warp the text element, applying a transform algorithm to the text element to transform the linear orientation into a warped orientation;

obtaining a text effect selection of the warped orientation of the text element;

applying an inverse transform algorithm to the text effect selection of the warped text element, wherein the inverse transform algorithm is an inverse algorithm of the transform algorithm;

determining a location of the text effect selection in relation to the text element having the linear orientation based on the application of the inverse transform algorithm; and

applying the transform algorithm to a text effect related to the text effect selection to display the text effect at the determined location in the warped orientation of the text element.

9. The computer-readable storage medium of claim 8, wherein the text element includes at least one member of a group comprising:

a character, a letter, a number, a word, a symbol, a graph, and a picture.

10. The computer-readable storage medium of claim 8, wherein the text effect includes at least one member of a group comprising:

a highlight selection, an underline, and a strikethrough.

11. The computer-readable storage medium of claim 8, wherein the text effect selection relates to a cursor hit on the warped orientation.

12. The computer-readable storage medium of claim 11, wherein the text effect selection includes a cursor displayed rotated in accordance with the warped orientation.

13. The computer-readable storage medium of claim 8, wherein the text effect selection relates to a selection highlight block on the warped orientation.

14. The computer-readable storage medium of claim 13, wherein the selection highlight block is rotated in accordance with the warped orientation.

15. A system for selecting and formatting warped text, the instructions comprising:

a processor; and

a memory having computer executable instructions stored thereon, wherein the computer-executable instructions are configured for;

obtaining a text element having a linear orientation;

receiving a selection to warp the text element;

upon receiving the selection to warp the text element, applying a transform algorithm to the text element to transform the linear orientation into a warped orientation;

obtaining a text effect selection of the warped orientation of the text element;

applying an inverse transform algorithm to the text effect selection of the warped text element, wherein the inverse transform algorithm is an inverse algorithm of the transform algorithm;

determining a location of the text effect selection in relation to the text element having the linear orientation based on the application of the inverse transform algorithm; and

applying the transform algorithm to a text effect related to the text effect selection to display the text effect at the determined location in the warped orientation of the text element.

16. The system of claim 15, wherein the text effect includes at least one member of a group comprising:

a highlight selection, an underline, and a strikethrough.

17. The system of claim 15, wherein the text effect selection relates to a cursor hit on the warped orientation.

18. The system of claim 17, wherein the text effect selection includes a cursor displayed rotated in accordance with the warped orientation.

19. The system of claim 15, wherein the text effect selection relates to a selection highlight block on the warped orientation.

20. The system of claim 19, wherein the selection highlight block is rotated in accordance with the warped orientation.
