How to use the Demo application:

• Click anywhere inside the drawing canvas above to plot a point.
• Plot as many number of points as you wish and click any one of the "Draw Line", "Draw Polyline", "Draw Polygon" or "Fill Polygon" buttons on right side
• Check the output with various parameters like pen width and color. Please note that last 2 points will be used for drawing a line on clicking "Draw Line" button.
• "Clear Canvas" button is to clear the canvas completely.
• "Clear Previous Points Set" button is to clear the old set of points from the memory only. For next drawing only newly plotted set of points will be used but old diagrams will remain on the canvas only.
• If you find some bug/defect in the demo application, please report the bug with "Points Data".
