public DPIPortC<ImageC<ByteT>>

DPIImageJPegByteGreyC(const StringC & fn)

Constructor from filename.

DPIImageJPegByteGreyC(const IStreamC & strm)

Constructor from stream

ImageC<ByteT> Get()

Get next piece of data.

bool Get(ImageC<ByteT> & buff)

Try and get next piece of data.
If none, return false. else put data into buff.

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

Get an array of data from stream.
returns the number of elements processed.

const type_info & InputType() const

Get type of input port.

bool IsGetReady() const

Is valid data.

bool IsGetEOS() const

Is valid data.

bool Discard()

Discard the next input datum.
returns true on success.

bool IsAsync() const

Does port work asynchronously ??

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.

StringC GetAttr(const StringC & attrName)

Get a stream attribute.
Return the value of an attribute or an empty string if its unkown. 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.

const DPEntityC & operator =(const DPEntityC & dat)

Assignment.

DPEntityBodyC & Body()

Access body.

const DPEntityBodyC & Body() const

Access body.

bool Save(ostream & out) const

Save to stream 'out'.

bool Save(BinOStreamC & out) const

Save to binary stream 'out'.

RCAbstractC Abstract()

Create an abstract handle.

istream & operator >>(istream & strm,RCHandleVC<DPEntityBodyC> & obj)

BinIStreamC & operator >>(BinIStreamC & strm,RCHandleVC<DPEntityBodyC> & obj)

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

Assign handle.

RCHandleC<DPEntityBodyC> DeepCopy(UIntT levels = ((UIntT))) const

Do a deep copy of the object.

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

Are handles to the same object ?

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

Are handles to different objects ?

UIntT Hash() const

Default hash function.
This hashes on the address of the body.

bool IsValid() const

Test if this is a valid handle.

void Invalidate()

Invalidate this handle.
Unattaches the body from the handle.

bool IsHandleType(const DT &) const

Is handle of given type ?

void CheckHandleType(const DT & dummy) const

Check handle type. Throw an expception if not.

UIntT References() const

Find the number of references to the body of this object.

ostream & operator <<(ostream & strm,const RCHandleC<DPEntityBodyC> & obj)

istream & operator >>(istream & strm,RCHandleC<DPEntityBodyC> & obj)
