Syntax

public class Transform2D : IDisposable

The Transform2D type exposes the following members.

Constructors

Name

Description

Public Method
Transform2D(Transform2D)

The copy constructor.

Public Method
Transform2D(UV, UV, UV)

Constructs the transformation by specifying the vectors and the origin.

Properties

Name

Description

Public Property

BasisU

The image of (1, 0) under OfVector(UV).

Public Property

BasisV

The image of (0, 1) under OfVector(UV).

Public Property
Determinant

The determinant of this transformation.

Public Property
HasReflection

The boolean value that indicates whether this transformation produces reflection (i.e., is orientation-reversing).

Public Property
IsConformal

The boolean value that indicates whether this transformation is conformal.

Public Property
IsIdentity

The boolean value that indicates whether this transformation is an identity.

Public Property
IsTranslation

The boolean value that indicates whether this transformation is a translation.

Public Property
IsValidObject

Specifies whether the .NET object represents a valid Revit entity.

Public Property

Origin

The image of (0, 0) under OfPoint(UV). This defines the translational part of the transform.

Public Property
Scale

The real number that represents the scale of the conformal transformation.

Methods

Name

Description

Public Method
AlmostEqual

Determines whether this transformation and the specified transformation are the same within the tolerance (1.0e-09).

Public Method

Assign

Assigns values from the input transformation to this transformation.

Public Method
Static Member
CreateIdentity

Creates the identity transformation.

Public Method

Dispose

Releases all resources used by the Transform2D

Public Method

Equals

Determines whether the specified object is equal to the current object.
(Inherited from Object)

Public Method

GetHashCode

Serves as the default hash function.
(Inherited from Object)

Public Method
GetInverse

Gets the inverse transformation of this transformation.

Public Method

GetType

Gets the Type of the current instance.
(Inherited from Object)

Public Method
Multiply

Multiplies this transformation by the specified transformation and returns the result.

Public Method
OfPoint

Applies the transformation to the point and returns the result.

Public Method
OfVector

Applies the transformation to the vector and returns the result.

Public Method
PostScale

Scales both the linear and translational parts of this transformation and returns the result.

Public Method
PreScale

Scales the linear part of this transformation and returns the result.

Public Method

SetToIdentity

Set this TrfUV to the identity transform.

Public Method

ToString

Returns a string that represents the current object.
(Inherited from Object)

Public Method
TransformUVDomainIfPossible

Transforms an envelope ( BoundingBoxUV) for one surface to an envelope for a coincident but differently parameterized surface.

Remarks

An affine transform is a linear transform plus a translation (which may be zero). Some functions only accept certain kinds of transform (e.g., rigid motion, conformal, non-singular, etc.).
