wx.GraphicsBitmap

Represents a bitmap.

The objects of this class are not created directly but only via wx.GraphicsContext or wx.GraphicsRenderer CreateBitmap(), CreateBitmapFromImage() or CreateSubBitmap() methods. They can subsequently be used with wx.GraphicsContext.DrawBitmap . The only other operation is testing for the bitmap validity, which can be performed using IsNull inherited from the base class.

Class API

class wx.GraphicsBitmap(GraphicsObject)

Possible constructors:

GraphicsBitmap() -> None

Represents a bitmap.

Methods

__init__(self)

Default constructor creates an invalid bitmap.

Return type:

None

---

ConvertToImage(self)

Return the contents of this bitmap as a wx.Image.

Using this method is more efficient than converting a wx.GraphicsBitmap to a wx.Bitmap first and then to a wx.Image. This can be useful if, for example, you want to save a wx.GraphicsBitmap in a file format not directly supported by wx.Bitmap.

Invalid image is returned if the bitmap is invalid.

Return type:

wx.Image

Added in version 2.9.3.

---

GetNativeBitmap(self)

Return the pointer to the native bitmap data.

( CGImageRef for Core Graphics, cairo_surface_t for Cairo, Bitmap* for GDI+.)

Return type:

Any

Added in version 2.9.4.
