Inheritance diagram for vetOutput:

Public Types
enum
	Ignore this, it's a class-type definition, mostly used by VETLib WorkShop, sintax is a bit more complex than usual because of a VC6 BUG, it's the same as: const int vetClassType = VETCLASS_TYPE_OUTPUT;.
Public Member Functions
	vetOutput ()
	Default constructor is protected because this is an abstract class and instance cannot be created directly.
virtual	~vetOutput ()
virtual VETRESULT	setHeight (unsigned int value)=0
	Set current canvas' height.
virtual VETRESULT	setWidth (unsigned int value)=0
	Set current canvas' width.
virtual VETRESULT	importFrom (vetFrameYUV420 &img)=0
	Inherited class must implement this function, processing frames to specific output (device or stream).
virtual VETRESULT	importFrom (vetFrameRGB24 &img)=0
	Inherited class must implement this function, processing frames to specific output (device or stream).
virtual VETRESULT	importFrom (vetFrameT< unsigned char > &img)=0
	Inherited class must implement this function, processing frames to specific output (device or stream).
void	operator<< (vetFrameYUV420 &img)
	Input operator, import standard VETLib frame formats, current implementation calls directly importFrom() method.
void	operator<< (vetFrameRGB24 &img)
	Input operator, import standard VETLib frame formats, current implementation calls directly importFrom() method.
void	operator<< (vetFrameT< unsigned char > &img)
	Input operator, import standard VETLib frame formats, current implementation calls directly importFrom() method.

Detailed Description

Abstract class for all data outputs, implementations should encode VETLib data stream to a device (visualization or storage for example), inherited classes must implement data encoding throw importFrom() methods, base input operators (<<) make a direct call to these functions, inherited classes may obviously override current operators behaviour.

virtual VETRESULT vetOutput::importFrom (  vetFrameT< unsigned char > &  img  )  [pure virtual]

Inherited class must implement this function, processing frames to specific output (device or stream). Parameters: [in]  img  Greyscale VETLib Frame to be processed (encoded for example) Returns: VETRET_OK if everything is fine, VETRET_PARAM_ERR if frame is not valid, VETRET_INTERNAL_ERR or VETRET_ILLEGAL_USE else. Note: Input operator (<<) call directly this function. See also: operator << (vetFrameT&) Implemented in vetCodec_BMP, vetCodec_BMP, vetCodec_IMG, vetCodec_MOV, vetCodec_MPEG, vetCodec_XVID, vetDigitalFilter, vetFilterColor, vetFilterGeometric, vetFilterNoiseChannel, vetMultiplexer, vetDoctor, vetOutputVoid, vetWindow32, vetWindowGTK, vetWindowQT, vetCodec, vetFilter, vetMotionIlluminationInvariant, and vetMotionLame.
