---|
| 15 | fillPolygon method implemented by Matthieu Haller. |
---|
| 16 | |
---|
| 17 | High Performance JavaScript Graphics Library. |
---|
| 18 | Provides methods |
---|
| 19 | - to draw lines, rectangles, ellipses, polygons |
---|
| 20 | with specifiable line thickness, |
---|
| 21 | - to fill rectangles, polygons, ellipses and arcs |
---|
| 22 | - to draw text. |
---|
| 23 | NOTE: Operations, functions and branching have rather been optimized |
---|
| 24 | to efficiency and speed than to shortness of source code. |
