AutoCAD Raster Design toolset provides several tools for modifying images.
- Cleanup. Correct scanning errors or minor imperfections in bitonal images. You can deskew, despeckle, touchup, adjust the bias, invert, or mirror an image.
- Image Processing. Adjust the appearance of an image. For example, you can use the convolve filter to reduce harshness or noise in an image.
- Raster Entity Manipulation (REM). Edit raster entities in bitonal, color, and grayscale images. For example, you can adjust the radius of a raster circle, remove dimension lines on a mechanical drawing, or use REM to copy electrical symbols from one image to another.
- Mask. Clip images inside the mask boundary and hide or unload images outside the mask boundary. A mask does not permanently alter an image.
- Crop. Delete data outside a selected area. The image frame size is adjusted automatically. A crop permanently alters an image.
- Remove. Rub raster data within an image or across multiple images. The only images affected are those within, or partly within, the selected entity or area.
- Merge. Merge images, merge vectors into raster data, and select raster pen widths.
- Properties. Adjust the attributes of an image such as position or transparent color.
