IDigitizerSetup Interface

Provides access to members that define the transformation used by the digitizer.

Product Availability

Available with ArcGIS Desktop.

When To Use

The IDigitizerSetup object can be used to modify the transformation properties used when transforming digitizer coordinates to map units using control points defined using the Editor.

Members

	Name	Description
	AddControlPoint	Adds a control point to the transformation.
	ClearControlPoints	Removes all control points.
	ControlPointCount	The number of control points used for digitizing.
	GetControlPoint	A control point's X,Y coordinates in Digitizer and Map units.
	Transformation	The transformation used by the digitizer.

Classes that implement IDigitizerSetup

Classes	Description
DigitizerExtension	Extension for working with the digitizer.

Remarks

The IDigitizerSetup uses an affine transformation to transform digitizer coordinates to map units. The transformation is based on control points.

The affine transformation can differentially scale, skew, rotate and translate your data. Using the Transformation method located on the IDigitizerSetup interface you can control the parameters used to perform these affine functions.
