Description
This is a simple console drawing program in Java.
The program works as follows:
- Create a new canvas
- Draw on the canvas by issuing various commands
- Quit
| Command | Description |
|---|---|
| C w h | Create a new canvas of width w and height h. |
| L x1 y1 x2 y2 | Draw a new line from (x1,y1) to (x2,y2). Currently, only |
| horizontal or vertical lines are supported. Horizontal and vertical lines | |
| will be drawn using the 'x' character. | |
