Abstract base class for graph drawers that draw on a Cairo canvas.

Method __init__ Constructs the graph drawer and associates it to the given Cairo context and the given BoundingBox.

Static Method	`ensure_layout`	Helper method that ensures that layout is an instance of `Layout`. If it is not, the method will try to convert it to a `Layout` according to the following rules:
Method	`draw`	Abstract method, must be implemented in derived classes.
Static Method	`_determine_edge_order`	Returns the order in which the edge of the given graph have to be drawn, assuming that the relevant keyword arguments (`edge_order` and `edge_order_by`) are given in `kwds` as a dictionary. If neither `edge_order`...
Static Method	`_determine_vertex_order`	Returns the order in which the vertices of the given graph have to be drawn, assuming that the relevant keyword arguments (`vertex_order` and `vertex_order_by`) are given in `kwds` as a dictionary. If neither ...

Method	`bbox.setter`	Sets the bounding box of the drawing area where this drawer will draw.
Instance Variable	`context`	Undocumented
Property	`bbox`	The bounding box of the drawing area where this drawer will draw.
Method	`_mark_point`	Marks the given point with a small circle on the canvas. Used primarily for debugging purposes.
Instance Variable	`_bbox`	Undocumented

def __init__(self, context, bbox): ¶

overrides igraph.drawing.cairo.base.AbstractCairoDrawer.__init__

overridden in igraph.drawing.cairo.graph.CairoGraphDrawer

Constructs the graph drawer and associates it to the given Cairo context and the given BoundingBox.

Parameters
context	the context on which we will draw
bbox	the bounding box within which we will draw. Can be anything accepted by the constructor of `BoundingBox` (i.e., a 2-tuple, a 4-tuple or a `BoundingBox` object).
