Struct Quadrilateral

Namespace

GrapeCity.Documents.Common

Assembly

GcDocs.Imaging.dll

Represents a quadrilateral defined by its four vertices's.

public struct Quadrilateral : IEquatable<Quadrilateral>

Implements

System.IEquatable<T><Quadrilateral>

Inherited Members

object.Equals(object, object)

object.ReferenceEquals(object, object)

object.GetType()

Constructors

Quadrilateral(PointF, PointF, PointF, PointF)

Initializes a new instance of the Quadrilateral struct from the four corners of a rectangle.

The vertices's of the quadrilateral correspond to the corners of the rectangle clockwise starting from the bottom left vertex.

public Quadrilateral(PointF bottomLeft, PointF topLeft, PointF topRight, PointF bottomRight)

Parameters

bottomLeft System.Drawing.PointF

The rectangle's bottom left corner.

topLeft System.Drawing.PointF

The rectangle's top left corner.

topRight System.Drawing.PointF

The rectangle's top right corner.

bottomRight System.Drawing.PointF

The rectangle's bottom right corner.

Quadrilateral(RectangleF)

Initializes a new instance of the Quadrilateral struct from a rectangle.

The vertices's of the quadrilateral correspond to the corners of the rectangle clockwise starting from the bottom left vertex.

public Quadrilateral(RectangleF rect)

Parameters

rect System.Drawing.RectangleF

The rectangle.

Fields

A

The first vertex of the quadrilateral.

If initialized from a rectangle, corresponds to the rectangle's bottom left corner.

public PointF A

Field Value

System.Drawing.PointF

B

The second vertex of the quadrilateral.

If initialized from a rectangle, corresponds to the rectangle's top left corner.

public PointF B

Field Value

System.Drawing.PointF

C

The third vertex of the quadrilateral.

If initialized from a rectangle, corresponds to the rectangle's top right corner.

public PointF C

Field Value

System.Drawing.PointF

D

The fourth vertex of the quadrilateral.

If initialized from a rectangle, corresponds to the rectangle's bottom right corner.

public PointF D

Field Value

System.Drawing.PointF
