Raster Entity Manipulation (REM) enables you to edit raster entities more easily and accurately by temporarily converting them to vector-like objects. After the edit session, you can merge the REM objects back into the raster drawing or move them to a new drawing.
There are three types of REM objects: primitives, regions, and enhanced bitonal regions. You can use each of these object types differently as you edit raster data.
| REM object | Description | Image type(s) |
|---|---|---|
| Primitive | Contains a single raster line, arc, or circle. | Bitonal |
| Region | Contains all pixels within a selected region, including parts of entities. | Bitonal, grayscale, color |
| Enhanced bitonal region | Contains complete raster entities within a selected region. | Bitonal |
The following sections show how different selection methods produce different REM objects.
