public DPOPortC<class DataT>

DPOImagePNGC(FilenameC fn)

Constructor from filename.

DPOImagePNGC(const OStreamC & strm)

Constructor from stream.

DPOPortBodyC<ImageC<PixelT>> & Body()

Access body.

const DPOPortBodyC<ImageC<PixelT>> & Body() const

Access body.

BooleanT Put(const ImageC<PixelT> & dat)

Put data to stream
Returns true if data is put into stream succesfully.

IntT PutArray(const SArray1dC<ImageC<PixelT>> & data)

Put an array of data elements into a stream.
returns the number of elements processed from the array.

BooleanT IsPutReady() const

Is port ready for data ?

DPOPortBaseBodyC & Body()

Access body.

const DPOPortBaseBodyC & Body() const

Access body.

void PutEOS()

Put End Of Stream marker.

const type_info & OutputType() const

Get type of output port.

DPPortBodyC & Body()

Access body.

const DPPortBodyC & Body() const

Access body.

BooleanT IsAsync() const

Does port work asynchronously ??

DPPortC ConnectedTo() const

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

BooleanT 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.

BooleanT 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.

const DPEntityC & operator=(const DPEntityC & dat)

Assignment.

DPEntityBodyC & Body()

Access body.

const DPEntityBodyC & Body() const

Access body.

BooleanT Save(ostream & out) const

RCAbstractC Abstract()

Create an abstract handle to this object.

BooleanT IsHandleType(const DT &) const

Is handle of given type ?

void CheckHandleType(const DT & dummy) const

Check handle type. Throw an expception if not.

BooleanT Save(ostream & out) const

Save to ostream.

RCHandleAC<DPEntityBodyC> Copy() const

Creat a deep copy of this object.
protected:

BooleanT IsValid() const

Check its a valid handle.

BooleanT IsValidObject() const

Check its a valid handle, and that the object is pointed to is also valid.

RCHandleC<DPEntityBodyC> & operator=(const RCHandleC<DPEntityBodyC> & oth)

Assignment.

BooleanT operator==(const RCHandleC<DPEntityBodyC> & oth) const

Comparison operator.

BooleanT operator!=(const RCHandleC<DPEntityBodyC> & oth) const

Comparison operator.

UIntT Hash() const

Hash function.x

BooleanT IsConst() const

Is object constant ?

BooleanT IsNotConst() const

Is object not constant ?

void SetConst(void) const

Lock the object.
This is const as a convience though it actual modified the object, often object you wish to ensure are constant already have const set. protected:

void Invalidate()

Turn this into an invalid handle.

DPEntityBodyC & Body()

Direct access to body.

const DPEntityBodyC & Body() const

Constant access to body.
