class CairoPolygonDrawer(AbstractCairoDrawer):
Class that is used to draw polygons in Cairo.
The corner points of the polygon can be set by the points property of the drawer, or passed at construction time. Most drawing methods in this class also have an extra points argument that can be used to override the set of points in the points property.
| Method | __init__ |
Constructs a new polygon drawer that draws on the given Cairo context. |
| Method | draw_path |
Sets up a Cairo path for the outline of a polygon on the given Cairo context. |
| Method | draw |
Draws the polygon using the current stroke of the Cairo context. |
Inherited from AbstractCairoDrawer:
| Instance Variable | context |
Undocumented |
| Property | bbox |
The bounding box of the drawing area where this drawer will draw. |
| Method | bbox.setter |
Sets the bounding box of the drawing area where this drawer will draw. |
| Instance Variable | _bbox |
Undocumented |
| Method | _mark_point |
Marks the given point with a small circle on the canvas. Used primarily for debugging purposes. |
Constructs a new polygon drawer that draws on the given Cairo context.
| Parameters | context | the Cairo context to draw on |
| bbox | ignored, leave it at its default value | |
| points | the list of corner points |
Sets up a Cairo path for the outline of a polygon on the given Cairo context.
| Parameters | points | the coordinates of the corners of the polygon, in clockwise or counter-clockwise order. |
| corner_radius | if zero, an ordinary polygon will be drawn. If positive, the corners of the polygon will be rounded with the given radius. |
