DPOImagePNGBodyC(StringC fn)

Constructor from filename.

DPOImagePNGBodyC(const OStreamC & strm)

Constructor from filename.
Not supported at the moment...

bool Put(const ImageC<PixelT> & dat)

Put data.

bool IsPutReady() const

Is port ready for data ?

bool Write(const ImageC<PixelT> & img)

Write an image.

bool Put(const ImageC<PixelT> &)

Put data.
This function MUST be provided by client class.

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

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

const type_info & OutputType() const

Input type.

bool Save(ostream & out) const

Save to ostream.

bool WriteHeader(const type_info & ti,const ImageRectangleC & nimgRect)

Write header information.

void PutEOS()

Put End Of Stream marker.

bool IsPutReady() const

Is port ready for data ?

const type_info & OutputType() const

Output type.

bool Save(ostream & out) const

Save to ostream.

bool IsAsync() const

Does port work asynchronously ?

bool Save(ostream & out) const

Save to ostream.

DPPortC ConnectedTo() const

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.

bool Save(ostream & out) const

Save to ostream.

bool Save(BinOStreamC & out) const

Save to binary stream.

RCBodyVC & Copy() const

Creat a copy of this object.

bool Save(ostream & out) const

Save to stream 'out'.

bool Save(BinOStreamC & out) const

Save to binary stream 'out'.

RCBodyVC & Copy() const

Make copy of body.
This should be provided in derived classes. this funtion will issue an assertion failure if called.

RCBodyC & DeepCopy(UIntT levels = ((UIntT))) const

Make a deep copy of body.
This should be provided in derived classes. this funtion will issue an assertion failure if called.

UIntT References() const

Access count of handles open to this object.

RCBodyC & Copy() const

Make copy of body.
This should be provided in derived classes. this funtion will issue an assertion failure if called.

RCBodyC & DeepCopy(UIntT levels = ((UIntT))) const

Make a deep copy of body.
This should be provided in derived classes. this funtion will issue an assertion failure if called.

void IncRefCounter()
