| Name | Type | Access | Description |
|---|---|---|---|
| disposed | bool | r | Gets a value indicating whether this instance is disposed. |
| opacity | float | r/w | Gets or sets the brush opacity. The value should be between 0 and 1. Value of 0 means that brush is fully visible, value of 1 means the brush is fully opaque. |
Methods
| Name | Description |
|---|---|
| deep_clone() | Creates a new deep clone of the current Brush. |

Examples
This example uses Graphics class to create primitive shapes on the Image surface. To demonstrate the operation, the example creates a new Image in PNG format and draw primitive shapes on Image surface using Draw methods exposed by Graphics class
