Detailed Description

Represents a line segment in a particular coordinate system.

Represents a line segment in a particular coordinate system. This class is immutable.

Constructor & Destructor Documentation

LineSegment()

iText.Kernel.Geom.LineSegment.LineSegment ( Vector  startPoint, Vector  endPoint  )

inline

Creates a new line segment.

Parameters

startPoint	the start point of a line segment.
endPoint	the end point of a line segment.

Member Function Documentation

ContainsPoint()

virtual bool iText.Kernel.Geom.LineSegment.ContainsPoint ( Vector  point )

inlinevirtual

Checks if a segment contains a given point in itself

Parameters

point

a point to be checked

Returns

true if this segment contains given point, false otherwise

ContainsSegment()

virtual bool iText.Kernel.Geom.LineSegment.ContainsSegment ( iText.Kernel.Geom.LineSegment  other )

inlinevirtual

Checks if a segment contains another segment in itself

Parameters

other

a segment to be checked

Returns

true if this segment contains other one, false otherwise

GetBoundingRectangle()

virtual Rectangle iText.Kernel.Geom.LineSegment.GetBoundingRectangle ( )

inlinevirtual

Computes the bounding rectangle for this line segment.

Computes the bounding rectangle for this line segment. The rectangle has a rotation 0 degrees with respect to the coordinate system that the line system is in. For example, if a line segment is 5 unit long and sits at a 37 degree angle from horizontal, the bounding rectangle will have origin of the lower left hand end point of the segment, with width = 4 and height = 3.

Returns

the bounding rectangle

TransformBy()

virtual iText.Kernel.Geom.LineSegment iText.Kernel.Geom.LineSegment.TransformBy ( Matrix  m )

inlinevirtual

Transforms the segment by the specified matrix

Parameters

m	the matrix for the transformation

Returns

the transformed segment
