Graphics Menu

The Graphics menu contains entries for interactive line graphics editing in the canvas window. The line graphics are normally restricted to the area of the image. For convenience, the menu offers the same functions as are available in the popup window:

The top of the Canvas Graphics popup has an area for setting the drawing mode. The other items are used for setting options, such as line width, arrow type, fill and outline color. These all correspond to the canvas item options of the same name. The CanvasDraw widget that implements the line graphics here is a generic canvas graphics widget and not RTD specific. It is part of the tclutil package, on which the rtd package is based.
