Abstract

Style extensibility is provided to shapes in a diagram by editing text files. A structured data model is used to render the diagram representing items provided by the user in a text-based format such as a bulleted list. A style engine determines style properties for style labels assigned to key shapes of the diagram. Style properties include features associated with the shapes and their content that preserve an overall look-and-feel of the diagram. Color scheme(s) are also provided through the style labels. A layout engine uses layout definitions based on user input and default parameters along with style label assignments to render a presentation model. Style properties may be modified and new styles added after the diagram is rendered.

Claims

1. A system for providing style extensibility in a diagram, the system comprising:

a semantic model in the form of a text-based tree diagram of lines of text entered by a user that create and define elements in the diagram and hierarchical relationships between each of the elements of the diagram, wherein a hierarchical level for each of the elements within the diagram is based on a position of each line of text entered by the user within the semantic model, and wherein each element that is located on a different line in the semantic model is displayed as a different element within the diagram determined from the semantic model;

a style label assigned to each of the elements of the diagram based on the hierarchical level of each of the elements within the semantic model of the defined hierarchical relationships such that each element at a same hierarchical level is assigned a same style label, wherein the style label associates the elements of the diagram with style definitions independent of a layout definition, and wherein the elements of the diagram comprise;

objects, connectors and content; and

a style definition for each object of the diagram generated from the semantic model determined by locating a matching style label within a file that comprises style definitions, wherein the diagram is rendered based on the layout definition and the determined style definitions.

2. The system of claim 1, further comprising a color scheme for each object of the diagram based on a color definition wherein the style label further associates the object with the color definition.

3. The system of claim 2, wherein at least one of a style or a color scheme of the diagram is dynamically modified by modifying the style definition and the color definition respectively.

4. The system of claim 1, wherein the diagram is rendered by providing a presentation model on a canvas based on the layout definition, the style definition, and the color definition for each object.

5. The system of claim 4, wherein the style definition includes property information for at least one of:

an outline style, a fill style, a font, a text attribute, a text effect, or an outline effect associated with the object.

6. The system of claim 5, wherein the text attribute includes at least one of:

a bold text, an italic text, an underlined text, a strike-through text;

the text effect includes at least one of;

a shadow effect, a 3D effect, and an embossing effect; and

the outline effect includes at least one of;

a shadow effect, a 3D effect, or an engraving effect.

7. The system of claim 1, wherein the layout definition specifies a size and a position of each object of the diagram.

8. The system of claim 1, wherein the semantic model includes items to be represented by the objects in the diagram such that an attribute of each item determines a hierarchical status of the associated object.

9. The system of claim 8, wherein the attribute of each item includes at least one of:

a tab position or a line position of the item in relation to the other items in the semantic model.

10. The system of claim 1, wherein the style definition includes property information associated with at least one of:

a text, a graphic, or an image associated with each object of the diagram.

11. The system of claim 1, wherein the diagram is a part of at least one of:

a word processing application, a presentation application, or a spreadsheet application.

12. A method for providing style extensibility to a group of objects in a diagram based on text files, the method comprising:

receiving a semantic model in the form of a text-based tree diagram of lines of text entered by a user that is used to create and define objects to include in the diagram and hierarchical relationships between objects of the diagram based on a position of each line of text entered by the user within the semantic model, and wherein each line of text entered by the user in the semantic model is displayed as a different object within the diagram;

determining an object, a connector, and a content for the object based on the semantic model and a default parameter;

determining a style definition for the object by matching an assigned style property for the object such that each object at a same hierarchical level receives a same style definition; and

rendering a presentation model for the diagram based on the semantic model, the default parameter, and the style definition for the object;

assigning the style property to the object using a style label that is assigned to the object based on a hierarchy defined by the semantic model such that the style property can be modified independent of a layout of the object.

13. The method of claim 12, further comprising assigning a color scheme property to the object independent of the style property.

14. The method of claim 12, wherein the style property includes at least one of:

an outline style, a fill style, a font, a text attribute, a text effect, or an outline effect associated with the object.

15. The method of claim 12, further comprising preserving the assigned style property and the color property of the object when the layout is modified.

16. The method of claim 12, further comprising determining a color scheme for each object of the diagram based on a color definition, wherein the style label further associates the object with the color definition.

17. The method of claim 16, further comprising dynamically modifying at least one of:

a style or a color scheme of the diagram by modifying the style definition and the color definition respectively.

18. The method of claim 12, further comprising rendering the diagram includes providing a presentation model on a canvas based on the layout definition, the style definition, and the color definition for each object.

19. The method of claim 12, further comprising the layout definition specifying a size and a position of each object of the diagram.

20. The method of claim 12, wherein the style definition associates style information with a connector of the diagram.
