CBitmap::CreateCompatibleBitmap

Initializes the object with a bitmap so that it is compatible with a specified device.

CBitmap::CreateDiscardableBitmap

Initializes the object with a discardable bitmap that is compatible with a specified device.

CBitmap::FromHandle

Returns a pointer to a CBitmap object when given a handle to a Windows HBITMAP bitmap.

CBitmap::GetBitmap

Fills a BITMAP structure with information about the bitmap.

CBitmap::GetBitmapBits

Copies the bits of the specified bitmap into the specified buffer.

CBitmap::GetBitmapDimension

Returns the width and height of the bitmap. The height and width are assumed to have been set previously by the SetBitmapDimension member function.
