	Returns the lengths of the run the iterator is currently over.

Detailed Description

Iterator to the runs of a coded element.

Remarks:

This class is responsible for the sequential access to the individual runs of a coded element.

A run is defined as a maximal sequence of consecutive pixels on the same run, that all belong to the same coded element.

Constructor & Destructor Documentation

__init__() [1/2]

None eVision.EObjectRunsIterator.__init__	(		self,
		eVision.ECodedElement	codedElement )

Constructs an iterator to the runs of a coded element.

Parameters

codedElement

The coded element of interest, in the case the iterator is to be constructed from a given coded element.

__init__() [2/2]

None eVision.EObjectRunsIterator.__init__	(		self,
		eVision.EObjectRunsIterator	other )

Constructs an iterator to the runs of a coded element.

Parameters

other

The iterator to be copied, in the case of the copy constructor.

Member Function Documentation

First()

None eVision.EObjectRunsIterator.First

(

self

)

Rewinds to the first run of the coded element.

IsDone()

bool eVision.EObjectRunsIterator.IsDone

(

self

)

Tests whether all the runs have been spanned.

Next()

None eVision.EObjectRunsIterator.Next

(

self

)

Advance to the next run in the iterator.

Remarks:

An exception is thrown if the iterator has reached its end. Use eVision.EObjectRunsIterator.IsDone to check this condition.

Property Documentation

EndX

eVision.EObjectRunsIterator.EndX = property(_EndX__getter, None)

static

Returns the abscissa (X-coordinate) of the rightmost pixel of the run the iterator is currently over.

Remarks:

An exception is thrown if the iterator has reached its end. Use eVision.EObjectRunsIterator.IsDone to check this condition.

Length

eVision.EObjectRunsIterator.Length = property(_Length__getter, None)

static

Returns the lengths of the run the iterator is currently over.

Remarks:

An exception is thrown if the iterator has reached its end. Use eVision.EObjectRunsIterator.IsDone to check this condition.

StartX

eVision.EObjectRunsIterator.StartX = property(_StartX__getter, None)

static

Returns the abscissa (X-coordinate) of the leftmost pixel of the run the iterator is currently over.

Remarks:

An exception is thrown if the iterator has reached its end. Use eVision.EObjectRunsIterator.IsDone to check this condition.

Y

eVision.EObjectRunsIterator.Y = property(_Y__getter, None)

static

Returns the ordinate (Y-coordinate) of the run the iterator is currently over.

Remarks:

An exception is thrown if the iterator has reached its end. Use eVision.EObjectRunsIterator.IsDone to check this condition.
