ITransform2D Interface

Provides access to methods for transforming geometries using either specific parameters or arbitrary transformation objects (affine transformations, geographic transformations, etc.).

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

When To Use

ITransform2D is a generic interface implemented by most elements and geometries (i.e., CircleElement, FrameElement, Point, Line, Polygon, etc.).  Use this interface when you want to update the position of the element or geometry through some type of Euclidan 2D transformation opertion (move, rotate, scale, or transform).

Members

Name Description
Method Move Moves dx units horizontally and dy units vertically.
Method MoveVector Moves a direction and distance v. v can be in a different spatial reference than the geometry being moved.
Method Rotate Rotates about the specified origin point. The angle is in radians. The origin can be in a different spatial reference than the geometry being rotated.
Method Scale Scales about the specified origin using seperate horizonal and vertical scales. The origin point can be in a different spatial reference than the geometry being scaled.
Method Transform Applies an arbitrary transformation. In particular, the transformation parameter can be either an affine transformation or a geographic transformation (datum shift).
