class CMMFBitmapFrameBuffer : public CMMFBuffer;

Description

Class to store a frame of video data using an EPOC bitmap (RGB data).

Derivation

• CBase - Base class for all classes to be instantiated on the heap.

• CMMFBuffer - Abstract representation of a buffer to contain multimedia data.

• CMMFBitmapFrameBuffer - Class to store a frame of video data using an EPOC bitmap (RGB data).
