IMPORT_C ~CMMFBitmapFrameBuffer();

Description

Destructor.

static IMPORT_C CMMFBitmapFrameBuffer *NewL(const TSize &aSize, TDisplayMode aDisplayMode);

Description

Factory function to create objects of type CMMFBitmapFrameBuffer used to store a frame an EPOC bitmap. Allocates and constructs a bitmap frame buffer with the specified size and display mode.

Parameters

const TSize &aSize The bitmap frame buffer size. TDisplayMode aDisplayMode The display mode.

Return value

CMMFBitmapFrameBuffer * A pointer to a fully constructed CMMFBitmapFrameBuffer.

static IMPORT_C CMMFBitmapFrameBuffer *NewL(TInt aBitmapHandle);

Description

Factory function to create objects of type CMMFBitmapFrameBuffer used to store a frame using an EPOC bitmap.

Parameters

TInt aBitmapHandle The handle to the bitmap from which to make a copy.

Return value

CMMFBitmapFrameBuffer * A pointer to a fully constructed CMMFBitmapFrameBuffer.

virtual inline TUint BufferSize() const;

Description

Dummy implementation. Not applicable to bitmap frame data.

Return value

TUint Always zero for bitmap frames

inline CFbsBitmap *Data();

Description

Retrieves the frame data.

Return value

CFbsBitmap * A pointer to a bitmap containing the frame data.
