CBitmap Class

Encapsulates a Windows graphics device interface (GDI) bitmap and provides member functions to manipulate the bitmap.

class CBitmap : public CGdiObject

Members

Public Constructors

Name	Description
CBitmap::CBitmap	Constructs a CBitmap object.

Public Methods

Name	Description
CBitmap::CreateBitmap	Initializes the object with a device-dependent memory bitmap that has a specified width, height, and bit pattern.
CBitmap::CreateBitmapIndirect	Initializes the object with a bitmap with the width, height, and bit pattern (if one is specified) given in a BITMAP structure.
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.
CBitmap::LoadBitmap	Initializes the object by loading a named bitmap resource from the application's executable file and attaching the bitmap to the object.
CBitmap::LoadMappedBitmap	Loads a bitmap and maps colors to current system colors.
CBitmap::LoadOEMBitmap	Initializes the object by loading a predefined Windows bitmap and attaching the bitmap to the object.
CBitmap::SetBitmapBits	Sets the bits of a bitmap to the specified bit values.
CBitmap::SetBitmapDimension	Assigns a width and height to a bitmap in 0.1-millimeter units.

Public Operators

Name	Description
CBitmap::operator HBITMAP	Returns the Windows handle attached to the CBitmap object.

Remarks

To use a CBitmap object, construct the object, attach a bitmap handle to it with one of the initialization member functions, and then call the object's member functions.
