public DPImageCifBaseBodyC

IStreamC strm;

DPIImageCifBodyC(const IStreamC & nStrm,const StringC & suffix = "cif")

Constructor from stream

DPIImageCifBodyC(const IStreamC & nStrm,const Index2dC & size)

Constructor from stream

bool Seek(UIntT off)

Seek to location in stream.
Returns FALSE, if seek failed. (Maybe because its not implemented.) if an error occurered (Seek returned False) then stream position will not be changed.

bool DSeek(IntT off)

Delta Seek, goto location relative to the current one.

UIntT Tell() const

Find current location in stream.

UIntT Size() const

Find the total size of the stream.

ImageC<ByteYUVValueC> Get()

Get next image.

bool Get(ImageC<ByteYUVValueC> & buff)

Get next image.

bool IsGetReady() const

Is some data ready ?
TRUE = yes. Defaults to !IsGetEOS().

bool IsGetEOS() const

Has the End Of Stream been reached ?
TRUE = yes.

bool SetupForVariant(const StringC & suffix)

Setup for cif variant.
str should be one of : sqcif,qcif,cif,4cif,16cif

bool SetupForVariant(const Index2dC & size)

Setup for cif variant.
Where size in the size of the Y image.

UIntT CalcOffset(UIntT frameNo) const

Calculate the offset of a frame.

IntT CalcOffset(IntT frameNo) const

Calculate the offset of a frame.

void SetSequenceSize(UIntT val)

Set the sequence size.

UIntT SeqSize() const

Get the sequence size.

ImageC<ByteYUVValueC> Get()

Get next piece of data.
May block if not ready, or it could throw an DataNotReadyC exception. NB. This function MUST be provided by client class.

bool Get(ImageC<ByteYUVValueC> & buff)

Try and get next piece of data.
This may not NOT block, if no data is ready it will return false, and not set buff. NB. The default version of this function uses the Get() method defined above and so need not be provided by derived classes.

IntT GetArray(SArray1dC<ImageC<ByteYUVValueC>> & data)

Get an array of data from stream.
returns the number of elements succesfully processed. NB. This need NOT be overridden in client classes unless fast handling of arrays of data elements is required.

const type_info & InputType() const

Input type.

bool Save(ostream & out) const

Save to ostream.

bool Discard()

Discard the next input datum.

bool Seek(UIntT off)

Seek to location in stream.
Returns false, if seek failed. (Maybe because its not implemented.) if an error occurered (Seek returned False) then stream position will not be changed.

bool DSeek(IntT off)

Delta Seek, goto location relative to the current one.
The default behavour of this functions is : Do some error checking then: Seek((UIntT)((IntT) Tell() + off)); if an error occurered (DSeek returned False) then stream position will not be changed.

UIntT Tell() const

Find current location in stream.
Defined as the index of the next object to be written or read. May return ((UIntT) (-1)) if not implemented.

UIntT Size() const

Find the total size of the stream. (assuming it starts from 0)
May return ((UIntT) (-1)) if not implemented.

UIntT Start() const

Find the offset where the stream begins, normally zero.
Defaults to 0

bool IsGetReady() const

Is some data ready ?
true = yes. Defaults to !IsGetEOS().

bool IsGetEOS() const

Has the End Of Stream been reached ?
true = yes.

const type_info & InputType() const

Input type.

bool Save(ostream & out) const

Save to ostream.

Is this port connected to another ?
If not returns invalid handle.

bool GetAttr(const StringC & attrName,StringC & attrValue)

Get a stream attribute.
Returns false if the attribute name is unknown. This is for handling stream attributes such as frame rate, and compression ratios.

bool SetAttr(const StringC & attrName,const StringC & attrValue)

Set a stream attribute.
Returns false if the attribute name is unknown. This is for handling stream attributes such as frame rate, and compression ratios.
