Detailed Description

As subpath is a part of a path comprising a sequence of connected segments.

Constructor & Destructor Documentation

Subpath() [1/4]

iText.Kernel.Geom.Subpath.Subpath ( )

inline

Creates a new SubPath instance.

Subpath() [2/4]

iText.Kernel.Geom.Subpath.Subpath ( iText.Kernel.Geom.Subpath  subpath )

inline

Copy constructor.

Parameters

subpath

Subpath which contents will be used to create this Subpath

Subpath() [3/4]

iText.Kernel.Geom.Subpath.Subpath ( Point  startPoint )

inline

Constructs a new subpath starting at the given point.

Parameters

startPoint

the point this subpath starts at

Subpath() [4/4]

iText.Kernel.Geom.Subpath.Subpath ( float  startPointX, float  startPointY  )

inline

Constructs a new subpath starting at the given point.

Parameters

startPointX	x-coordinate of the start point of subpath
startPointY	y-coordinate of the start point of subpath

Member Function Documentation

AddSegment()

virtual void iText.Kernel.Geom.Subpath.AddSegment ( IShape  segment )

inlinevirtual

Adds a segment to the subpath.

Adds a segment to the subpath. Note: each new segment shall start at the end of the previous segment.

Parameters

segment

new segment.

GetPiecewiseLinearApproximation()

virtual IList<Point> iText.Kernel.Geom.Subpath.GetPiecewiseLinearApproximation ( )

inlinevirtual

Returns

System.Collections.IList containing points of piecewise linear approximation for this subpath.

GetSegments()

virtual IList<IShape> iText.Kernel.Geom.Subpath.GetSegments ( )

inlinevirtual

Returns

System.Collections.IList comprising all the segments the subpath made on.

IsClosed()

virtual bool iText.Kernel.Geom.Subpath.IsClosed ( )

inlinevirtual

Returns a boolean value indicating whether the subpath must be closed or not.

Returns a boolean value indicating whether the subpath must be closed or not. Ignore this value if the subpath is a rectangle because in this case it is already closed (of course if you paint the path using re operator)

Returns

boolean value indicating whether the path must be closed or not.

IsDegenerate()

virtual bool iText.Kernel.Geom.Subpath.IsDegenerate ( )

inlinevirtual

Returns a boolean indicating whether the subpath is degenerate or not.

Returns a boolean indicating whether the subpath is degenerate or not. A degenerate subpath is the subpath consisting of a single-point closed path or of two or more points at the same coordinates.

Returns

boolean value indicating whether the path is degenerate or not.

IsEmpty()

virtual bool iText.Kernel.Geom.Subpath.IsEmpty ( )

inlinevirtual

Checks whether subpath is empty or not.

Returns

true if the subpath is empty, false otherwise.

IsSinglePointClosed()

virtual bool iText.Kernel.Geom.Subpath.IsSinglePointClosed ( )

inlinevirtual

Returns

true if this subpath contains only one point and it is closed, false otherwise

IsSinglePointOpen()

virtual bool iText.Kernel.Geom.Subpath.IsSinglePointOpen ( )

inlinevirtual

Returns

true if this subpath contains only one point and it is not closed, false otherwise

SetClosed()

virtual void iText.Kernel.Geom.Subpath.SetClosed ( bool  closed )

inlinevirtual

See IsClosed()

Parameters

closed

boolean value indicating whether the path is closed or not.

SetStartPoint() [1/2]

virtual void iText.Kernel.Geom.Subpath.SetStartPoint ( float  x, float  y  )

inlinevirtual

Sets the start point of the subpath.

Parameters

x	x-coordinate of the start pint
y	y-coordinate of the start pint

SetStartPoint() [2/2]

virtual void iText.Kernel.Geom.Subpath.SetStartPoint ( Point  startPoint )

inlinevirtual

Sets the start point of the subpath.

Parameters

startPoint

the point this subpath starts at
