Detailed Description

Represents a bitmap.

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

wxImage wxGraphicsBitmap::ConvertToImage

(

)

const

Return the contents of this bitmap as wxImage.

Using this method is more efficient than converting wxGraphicsBitmap to wxBitmap first and then to wxImage and can be useful if, for example, you want to save wxGraphicsBitmap as a disk file in a format not directly supported by wxBitmap.

Invalid image is returned if the bitmap is invalid.
