wx.GraphicsPath¶A wx.GraphicsPath is a native representation of a geometric path.
The contents are specific and private to the respective renderer. Instances are reference counted and can therefore be assigned as usual. The only way to get a valid instance is by using wx.GraphicsContext.CreatePath or wx.GraphicsRenderer.CreatePath .
Methods Summary¶Adds an arc of a circle. |
|
Appends a an arc to two tangents connecting (current) to (x1,`y1`) and (x1,`y1`) to (x2,`y2`), also a straight line from (current) to (x1,`y1`). |
|
Appends a circle around (x,`y`) with radius r as a new closed subpath. |
|
Adds a cubic bezier curve from the current point, using two control points and an end point. |
|
Appends an ellipse fitting into the passed in rectangle. |
|
Adds a straight line from the current point to (x,`y`). |
|
Adds another path. |
|
Adds a quadratic bezier curve from the current point, using a control point and an end point. |
|
Appends a rectangle as a new closed subpath. |
|
Appends a rounded rectangle as a new closed subpath. |
|
Closes the current sub-path. |
|
Gets the bounding box enclosing all points (possibly including control points). |
|
Gets the last point of the current path, (0,0) if not yet set. |
|
Returns the native path (CGPathRef for Core Graphics, Path pointer for GDIPlus and a cairo_path_t pointer for cairo). |
|
Begins a new subpath at (x,`y`). |
|
Transforms each point of this path by the matrix. |
|
Gives back the native path returned by |
Class API¶
Inheritance diagram for class GraphicsPath:
wx.GraphicsPath(GraphicsObject)¶A GraphicsPath is a native representation of a geometric path.
AddArc(self, *args, **kw)¶Adds an arc of a circle.
The circle is defined by the coordinates of its centre (x, y) or c and its radius r. The arc goes from the starting angle startAngle to endAngle either clockwise or counter-clockwise depending on the value of clockwise argument.
The angles are measured in radians but, contrary to the usual mathematical convention, are always clockwise from the horizontal axis.
