Syntax

public class Transform1D : IDisposable

The Transform1D type exposes the following members.

Constructors

Name

Description

Public Method
Transform1D(Double)

Constructs the transformation by specifying the scale only.

Public Method
Transform1D(Transform1D)

The copy constructor.

Public Method
Transform1D(Double, Double)

Constructs the transformation by specifying the scale and the translation.

Properties

Name

Description

Public Property

Determinant

The determinant of this transformation.

Public Property
IsIdentity

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

Public Property
IsValidObject

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

Public Property

Scale

The real number that represents the scale of this transformation.

Public Property

Translation

The translational part of this 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

Dispose

Releases all resources used by the Transform1D

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 1-dimensional point and returns the result.

Public Method
OfVector

Applies the transformation to the 1-dimensional vector (a “tangent vector” on the real line) 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
TransformParameterDomain

Performs a transform of the parameter range defined by domain, and ensures that the domain is ordered correctly.

Remarks

An affine transform is a linear transform plus a translation (which may be zero). 1D space is tranformed according to the following formula: t -> A*t + B where A and B are constants. Some functions only accept certain kinds of transform (e.g., rigid motion, conformal, non-singular, etc.).
