Abstract

Systems, including handheld computing devices that include system code stored within the memory and adapted to be executed by the processor. The system code can process an input byte stream that is representative of contents to be displayed on the touch sensitive display and can generate a content document file representative of an internal representation of the content.

A tool document file may also be stored in the memory and may provide an internal representation of a document providing an image that is representative of a graphical tool. Associated with a tool document can be tool code that is capable of processing the content document file to create an internal representation of the contents that presents the content in a manner that achieves a display effect associated with the tool. The device will also include parsing code that processes the content document file, the tool document file, and the processed internal representation to generate a screen document for display on the touch sensitive display in a manner that portrays the display effect.

Claims

1. A computing device comprising:

a display; and

a processor configured to;

display the content of a document on the display,

in response to user input, adjust graphic properties of selected portions of the document, thereby adjusting the prominence of the selected portions relative to other portions of the document, and

display the content of the document using the adjusted graphic properties.

2. A computing device according to claim 1, wherein the selected portions of the document are hyperlinks.

3. A computing device according to claim 1, wherein the selected portions of the document are highlighted text.

4. A computing device according to claim 1, wherein the user input comprises a slider control.

5. A computing device according to claim 4, comprising a touch screen, and the processor is configured to accept input to the slider control via the touch screen.

6. A computing device according to claim 1, wherein the graphic properties of the selected portions of the document include alpha transparency, and relative prominence is adjusted by adjusting the alpha transparency of the selected portions of the document.

7. A method of adjusting graphic properties of selected portions of a document comprising:

displaying the content of a document on a display,

in response to user input, adjusting, by a processor, graphic properties of selected portions of the document, thereby adjusting the prominence of the selected portions relative to other portions of the document, and

displaying the content of the document on the display using the adjusted graphic properties.

8. A method according to claim 7, wherein the selected portions of the document are hyperlinks.

9. A method according to claim 7, wherein the selected portions of the document are highlighted text.

10. A method according to claim 7, wherein the user input comprises a slider control.

11. A method according to claim 7, comprising receiving the user input from a touch screen.

12. A method according to claim 7, wherein the graphic properties of the selected portions of the document include alpha transparency, and relative prominence is adjusted by adjusting the alpha transparency of the selected portions of the document.
