drawPath(Pen pen, GraphicsPath path)
public void drawPath(Pen pen, GraphicsPath path)
Draws a com.aspose.imaging.graphicsPath.
Parameters:
| Parameter | Type | Description |
|---|---|---|
| pen | Pen | com.aspose.imaging.Pen that determines the color, width, and style of the path. |
| path | GraphicsPath | com.aspose.imaging.GraphicsPath to draw. |
Example: This examples make use of GraphicsPath and Graphics class to create and manipulate Figures on an Image surface. This examples make use of GraphicsPath and Graphics class to create and manipulate Figures on an Image surface. Example creates a new Image (of type Tiff) and draw paths with the help of GraphicsPath class. At the end DrawPath method exposed by Graphics class is called to render the paths on surface.
