Load a byte image in PGM format.
include "Ravl/Image/ImgIOPNM.hh"
User Level:Normal
In Scope:RavlImageN

Parent Classes: Methods:
DPIImagePNMByteGreyC(const StringC & fn)
Constructor from filename.

DPIImagePNMByteGreyC(const IStreamC & strm)
Constructor from stream.

#include "Ravl/DP/Port.hh"
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.

#include "Ravl/DP/Entity.hh"
const DPEntityC & operator =(const DPEntityC & dat)

DPEntityBodyC & Body()
Access body.

const DPEntityBodyC & Body() const
Access body.

#include "Ravl/RCHandleV.hh"
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)

#include "Ravl/RefCounter.hh"
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)
