Raster snap modes make it easy to select exact positions on bitonal raster entities. Raster snap modes work like AutoCAD Object Snap modes, except that they snap to raster entities instead of to vector objects.
Raster snaps are useful when you want to
- Trace a raster entity with vectorization tools (VTools)
- Select a raster entity to rub or crop
- Select a raster entity to edit with raster entity manipulation (REM) commands
Note: Raster snapping works only with bitonal images.
When raster snapping is on (active), a snap window is displayed around the AutoCAD cursor. The snap window displays the crosshairs over points to which you can snap. You can select one or more snap modes to control whether the cursor snaps to endpoints, corners, and other points.
You can toggle Raster Snap on and off from the Snap panel on the Raster Tools tab of the ribbon.
