|phoenix_title| **wx.GraphicsBitmap**
==========================================================================================================================================
Represents a bitmap.
The objects of this class are not created directly but only via :ref:`wx.GraphicsContext` or :ref:`wx.GraphicsRenderer` CreateBitmap(), CreateBitmapFromImage() or CreateSubBitmap() methods. They can subsequently be used with :meth:`wx.GraphicsContext.DrawBitmap` . The only other operation is testing for the bitmap validity which can be performed using :meth:`~wx.GraphicsBitmap.IsNull` method inherited from the base class.

===============
.. class:: wx.GraphicsBitmap(GraphicsObject)
**Possible constructors**::
GraphicsBitmap()
Represents a bitmap.
.. method:: __init__(self)
Default constructor creates an invalid bitmap.
.. method:: ConvertToImage(self)
Return the contents of this bitmap as :ref:`wx.Image`.
Using this method is more efficient than converting :ref:`wx.GraphicsBitmap` to :ref:`wx.Bitmap` first and then to :ref:`wx.Image` and can be useful if, for example, you want to save :ref:`wx.GraphicsBitmap` as a disk file in a format not directly supported by :ref:`wx.Bitmap`.
Invalid image is returned if the bitmap is invalid.
:rtype: :ref:`wx.Image`
.. versionadded:: 2.9.3
.. method:: GetNativeBitmap(self)
Return the pointer to the native bitmap data.
(CGImageRef for Core Graphics, cairo_surface_t for Cairo, Bitmap for GDI+.)
.. versionadded:: 2.9.4
.. attribute:: NativeBitmap
See :meth:`~wx.GraphicsBitmap.GetNativeBitmap`
