Manipulating Raster Entities

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.
