IDxtCompositor Interface
The IDxtCompositor interface sets properties on the Compositor transition.
This interface is used internally by DirectShow Editing Services (DES) when it renders the Compositor transition. DES applications do not have to use this interface. To set the properties on a transition in DES, use the IPropertySetter interface.
The Compositor transition composites a foreground image onto a background image. The source rectangle defines the section of the foreground image that is composited. The destination rectangle defines the section of the background image that receives the foreground image. The following diagram illustrates these rectangles.

In addition to the methods inherited from IDXEffect, the IDxtCompositor interface exposes the following methods.
| Method | Description |
| get_Height | Retrieves the height of the target rectangle. |
| get_OffsetX | Retrieves the horizontal offset of the target rectangle. |
| get_OffsetY | Retrieves the vertical offset of the target rectangle. |
| get_SrcHeight | Retrieves the height of the source rectangle. |
| get_SrcWidth | Retrieves the width of the source rectangle. |
| get_SrcOffsetX | Retrieves the horizontal offset of the source rectangle. |
| get_SrcOffsetY | Retrieves the vertical offset of the source rectangle. |
| get_Width | Retrieves the width of the target rectangle. |
| put_Height | Specifies the height of the target rectangle. |
| put_OffsetX | Specifies the horizontal offset of the target rectangle. |
| put_OffsetY | Specifies the vertical offset of the target rectangle. |
| put_SrcHeight | Specifies the height of the source rectangle. |
