phoenix_title 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 .

method_summary Methods Summary

AddArc

Adds an arc of a circle.

AddArcToPoint

Adds an arc (of a circle with radius r) that is tangent to the line connecting current point and (x1, y1) and to the line connecting (x1, y1) and (x2, y2).

AddCircle

Appends a circle around (x,`y`) with radius r as a new closed subpath.

AddCurveToPoint

Adds a cubic bezier curve from the current point, using two control points and an end point.

AddEllipse

Appends an ellipse fitting into the passed in rectangle as a new closed subpath.

AddLineToPoint

Adds a straight line from the current point to (x,`y`).

AddPath

Adds another path onto the current path.

AddQuadCurveToPoint

Adds a quadratic bezier curve from the current point, using a control point and an end point.

AddRectangle

Appends a rectangle as a new closed subpath.

AddRoundedRectangle

Appends a rounded rectangle as a new closed subpath.

CloseSubpath

Closes the current sub-path.

Contains

GetBox

Gets the bounding box enclosing all points (possibly including control points).

GetCurrentPoint

Gets the last point of the current path, (0,0) if not yet set.

GetNativePath

Returns the native path (CGPathRef for Core Graphics, Path pointer for GDIPlus and a cairo_path_t pointer for cairo).

MoveToPoint

Begins a new subpath at (x,`y`).

Transform

Transforms each point of this path by the matrix.

UnGetNativePath

Gives back the native path returned by GetNativePath because there might be some deallocations necessary (e.g.

class wx.GraphicsPath(GraphicsObject)

A GraphicsPath is a native representation of a geometric path.


Methods

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.

If for clockwise arc endAngle is less than startAngle it will be progressively increased by 2pi until it is greater than startAngle. If for counter-clockwise arc endAngle is greater than startAngle it will be progressively decreased by 2pi until it is less than startAngle.

If there is a current point set, an initial line segment will be added to the path to connect the current point to the beginning of the arc.

AddArc (self, x, y, r, startAngle, endAngle, clockwise)

Parameters:
  • x (wx.Double)

  • y (wx.Double)

  • r (wx.Double)

  • startAngle (wx.Double)

  • endAngle (wx.Double)

  • clockwise (bool)

Return type:

None



AddArc (self, c, r, startAngle, endAngle, clockwise)

Parameters:
  • c (wx.Point2D)

  • r (wx.Double)

  • startAngle (wx.Double)

  • endAngle (wx.Double)

  • clockwise (bool)

Return type:

None





AddArcToPoint(self, x1, y1, x2, y2, r)

Adds an arc (of a circle with radius r) that is tangent to the line connecting current point and (x1, y1) and to the line connecting (x1, y1) and (x2, y2).

If the current point and the starting point of the arc are different, a straight line connecting these points is also appended. If there is no current point before the call to AddArcToPoint this function will behave as if preceded by a call to MoveToPoint(0, 0). After this call the current point will be at the ending point of the arc.
