Shape styles select a specific set of fill, stroke and font styles from a drawing theme and applies them to individual shapes. The shape style of a specific shape is controlled and configured through its ShapeStyle property. The shape style contains the following properties:

• FillStyleIndex - determines the index of the fill style to use.
• StrokeStyleIndex - determines the index of the stroke style to use.
• FontStyleIndex - determines the index of the font style to use.
• FillColorIndex - determines the index of the fill color to use.
• StrokeColorIndex - determines the index of the stroke color to use.
• FontColorIndex - determines the index of the font color to use.

The values of these properties select a unique style from the style matrix of the currently selected theme components:

 

The image above demonstrates how setting a value to the color index (blue) and style index (red) properties uniquely selects a style from the style matrix of the currently selected theme.

When the style index is set to 100 and the color index ranges from 100 to 103 a variant shape style is selected.

When the style index ranges from 0 to 5 and the color index is from 200 to 206 a theme shape style is selected.
