You can use the Merge to Raster Image command to merge REM objects into the source image or into another image.
This command merges all selected REM objects into the image under them. If your REM objects are not over an image, a merge operation is not possible. If your REM objects are partly touching the image, the image expands to accommodate them. If your REM objects are below the image, the objects merge into the image above. Unlike vector merge, display order is not respected.
If the selected REM objects are over multiple images or span adjacent images, a dialog box prompts you to choose an image.
If you defined a REM object but did not modify the object, clear the object to merge it into the source image. If you want to create a new image from the REM object, use the Convert to Raster Image command.
