Simple drawing implementation in Canvas created in Java.
The program supports the following commands:
| Command | Description |
|---|---|
C w h |
creates a new canvas of width w and height h. |
L x1 y1 x2 y2 |
creates 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. |
R x1 y1 x2 y2 |
creates a new rectangle, whose upper left corner is (x1,y1) and lower right corner is (x2,y2). Horizontal and vertical lines will be drawn using the x character. |
B x y c |
fills the entire area connected to (x,y) with colour 'c'. The behaviour of this is the same as that of the "bucket fill" tool in paint programs. |
Q |
quits the program. |
Below is a sample of the output the program produces. User input is prefixed with enter command:.
