Pen Tool

The Pen Tool allows the user to add freehand notes and drawings to the Graphics View. This makes the Pen Tool particularly useful when using GeoGebra for presentations or with multimedia interactive whiteboards.

The default color of the pen is black, but you can change the pen properties (color, style, and thickness) using the Toggle Styling Bar, selecting the first little icon displayed on the Graphics View bar.

Selecting a different tool ends the freehand drawing process.

GeoGebra stores the notes you have traced in the Graphic View as an Images:image, so you can do any image operations with it (move, rotate, delete, etc.).

Erasing

To erase a portion of your notes created in the Graphic View with the Pen Tool, press and hold the right mouse button while moving it on the notes you want to delete. Erasing is completed when you release the mouse button.
