Interfaces
| Interfaces | Description |
|---|---|
| IConnectionPointContainer (esriDisplay) | Supports connection points for connectable objects. |
| IDelayEvents | Provides access to members that control Delay Events. |
| IDisplayTransformation | Provides access to members that control Display Transformation. |
| IDisplayTransformationAdmin | Provides access to members that control the DisplayTransformation. |
| IDisplayTransformationScales | Provides access to members that control Display Transformation scales. |
| IOutputRasterSettings | Provides access to members that control New Raster Output Settings. |
| IRasterOutputSettings | Provides access to members that control Raster Output Settings. |
| ITransformation (esriGeometry) | Provides access to members that apply a function (or its inverse) to a set of points or measures. The suffix of each method indicates the type of parameters operated on. |
| ITransformationGEN (esriGeometry) | Provides access to members that apply a function (or its inverse) to a set of points or measures. The suffix of each method indicates the type of parameters operated on. ITransformationGEN is generic version of ITransformation. |

| ITransformEvents (default) | Provides access to members that control Transform Events. |
Remarks
Manages the map to device transformation. See IDisplayTransformation for information on how to prepare a transform for use.
Each DisplayTransformation object has a spatial reference object which manages the display's current coordinate system.
The DisplayTransformation is itself owned by a Display object, typically ScreenDisplay. Obtain an IDisplayTransformation reference to a DisplayTransformation object via IDisplay::DisplayTransformation; since IScreenDisplay inherits from IDisplay, you call also use IScreenDisplay::DisplayTransformation.
Working with Events
When working with DisplayTransformation's default outbound interface in Visual Basic 6 declare variables as follows: Private WithEvents pDisplayTransformation as DisplayTransformation
