Description
===========

A `wx.GraphicsRenderer` is the instance corresponding to the rendering engine used. There may be multiple instances on a system, 
if there are different rendering engines present, but there is always one instance per engine, eg there is ONE core graphics 
renderer instance on OSX. This instance is pointed back to by all objects created by it (`wx.GraphicsContext <wx.GraphicsContext.html>`_, 
`wx.GraphicsPath <wx.GraphicsPath.html>`_ etc...). 

Therefore you can create ag additional instances of paths etc. by calling `GetRenderer()` and then using the appropriate `CreateXXX` function.

.. method:: __init__()

   `No docstrings available for this method.` 

--------


.. method:: CreateBrush(brush)

   Creates a native brush from a `wx.Brush <wx.Brush.html>`_.

   **Parameters:**

   * `brush` (`wx.Brush <wx.Brush.html>`_) 

   |  

   **Returns:**

   `wx.GraphicsBrush <wx.GraphicsBrush.html>`_
 

--------

.. method:: CreateContext(dc)

   Creates a `wx.GraphicsContext` from a `wx.Window <wx.Window.html>`_.

   **Parameters:**

   * `dc` (`wx.WindowDC <wx.WindowDC.html>`_) 

   |  

   **Returns:**

   `wx.GraphicsContext <wx.GraphicsContext.html>`_
 

--------

.. method:: CreateContextFromNativeContext(context)

   Creates a `wx.GraphicsContext` from a native context. This native context must be eg a CGContextRef for Core Graphics, a Graphics 
   pointer for GDIPlus or a cairo_t pointer for cairo.

   **Parameters:**

   * `context` () 

   |  

   **Returns:**

   `wx.GraphicsContext <wx.GraphicsContext.html>`_
 

--------

.. method:: CreateContextFromNativeWindow(window)

   Creates a `wx.GraphicsContext` from a native window.

   **Parameters:**

   * `window` () 

   |  

   **Returns:**

   `wx.GraphicsContext <wx.GraphicsContext.html>`_
 

--------

.. method:: CreateFont(font, col=wx.BLACK)

   Creates a native graphics font from a `wx.Font <wx.Font.html>`_ and a text colour.

   **Parameters:**

   * `font` (`wx.Font <wx.Font.html>`_) 
   * `col` (`wx.Colour <wx.Colour.html>`_) 

   |  

   **Returns:**

   `wx.GraphicsFont <wx.GraphicsFont.html>`_
 

--------

.. method:: CreateLinearGradientBrush(x1, y1, x2, y2, c1, c2)

   Creates a native brush, having a linear gradient, starting at (`x1`, `y1`) with color `c1` to (`x2`, `y2`) with color `c2`.

   **Parameters:**

   * `x1` (double) 
   * `x2` (double) 
   * `y1` (double) 
   * `y2` (double) 
   * `c1` (`wx.Colour <wx.Colour.html>`_) 
   * `c2` (`wx.Colour <wx.Colour.html>`_) 

   |  

   **Returns:**

   `wx.GraphicsBrush <wx.GraphicsBrush.html>`_
  

--------

.. method:: CreateMatrix(a=1.0, b=0.0, c=0.0, d=1.0, tx=0.0, ty=0.0)

   Creates a native affine transformation matrix from the passed in values. The defaults result in an identity matrix.

   **Parameters:**

   * `a` (double) 
   * `b` (double) 
   * `c` (double) 
   * `d` (double) 
   * `tx` (double) 
   * `ty` (double) 

   |  

   **Returns:**

   `wx.GraphicsMatrix <wx.GraphicsMatrix.html>`_
 

--------

.. method:: CreateMeasuringContext()

   `No docstrings available for this method.` 

--------


.. method:: CreatePath()

   Creates a native graphics path which is initially empty.

   |  

   **Returns:**

   `wx.GraphicsPath <wx.GraphicsPath.html>`_
 

--------

.. method:: CreatePen(pen)

   Creates a native pen from a `wx.Pen <wx.Pen.html>`_.

   **Parameters:**

   * `pen` (`wx.Pen <wx.Pen.html>`_) 

   |  

   **Returns:**

   `wx.GraphicsPen <wx.GraphicsPen.html>`_
 

--------

.. method:: CreateRadialGradientBrush(xo, yo, xc, yc, radius, oColor, cColor)

   Creates a native brush, having a radial gradient originating at (`xo`, `yo`) with color `oColour` and ends on a circle 
   around (`xc`, `yc`) with radius `radius` and color `cColour`.

   **Parameters:**

   * `xo` (double) 
   * `yo` (double) 
   * `xc` (double) 
   * `yc` (double) 
   * `radius` (double) 
   * `oColor` (`wx.Colour <wx.Colour.html>`_) 
   * `cColor` (`wx.Colour <wx.Colour.html>`_) 

   |  

   **Returns:**

   `wx.GraphicsBrush <wx.GraphicsBrush.html>`_
 

--------

.. method:: GetDefaultRenderer()

   Returns the default renderer on this platform. On OS X this is the Core Graphics (a.k.a. Quartz 2D) renderer, on MSW the GDIPlus 
   renderer, and on GTK we currently default to the cairo renderer.

   |  

   **Returns:**

   `wx.GraphicsRenderer <wx.GraphicsRenderer.html>`_
