Raster editing is

The results of raster editing software can be saved not only as raster image files such as bmp/tiff/jpeg/png/gif/pdf, but also as vector data files such as dxf files. By using the OCR option, raster strings can be edited like text data and can also be targeted for string searches.

Copying processes that preserve the original image while moving and rotating vertices and shapes are also possible.
