| 8 | +---Represents a canvas object, as returned by the `gui.createcanvas()` method. |
| 9 | +---Note that the member functions do not have a `self` parameter, and so must be called with the regular invocation syntax, not the OOP syntax. |

If width and height are both nil/unset, the image will be drawn at full size (100%). If both are specified, the image will be stretched to that size. If true is passed for the cache parameter, or if it's omitted, the file contents will be cached and re-used next time this function is called with the same path on this canvas.

| 164 | +function LuaCanvas.DrawPixel(x, y, color) end |
| 165 | + |
| 166 | +---Draws a polygon (cyclic polyline) to the referenced canvas. The polygon must be given as a list of length-2 lists (co-ordinate pairs). Each pair is interpreted as the absolute co-ordinates of one of the vertices, and these are joined together in sequence to form a polygon. The last is connected to the first; you DON'T need to end with a copy of the first to close the cycle. If the x and y parameters are both specified, the whole polygon will be offset by that amount. If a value is passed for the line parameter, the polygon's edges are drawn in that color (i.e. the stroke color). If a value is passed for the background parameter, the polygon's face is filled in that color. |

| 168 | +---Example: |
| 169 | +--- |
| 170 | +--- canvas.DrawPolygon({ { 5, 10 }, { 10, 10 }, { 10, 20 }, { 5, 20 } }, 10, 30, 0x007F00FF, 0x7F7F7FFF); |

| 176 | +function LuaCanvas.DrawPolygon(points, x, y, line, background) end |
| 177 | + |
| 178 | +---Draws a rectangle at the given coordinate and the given width and height. Line is the color of the box. Background is the optional fill color |
| 179 | +--- |
| 180 | +---Example: |

| 207 | + |
| 208 | +---Draws the given message at the given x,y coordinates and the given color. The default color is white. A fontfamily can be specified and is monospace generic if none is specified (font family options are the same as the .NET FontFamily class). The fontsize default is 12.
