9.1 Basics of Vectorization
The program can convert scanned engineering and site plans with the help of OCR or
vectorization to DWG or DXF format. It is important to know that vectorization and OCR
(Optical Character Recognition) are two completely different procedures that convert
raster data into other formats.
Vectorization calculates the middle of a pixel trace at the edge of the pixel area or polygon
and iteratively smooths it.

In the OCR process, a pixel image is either recognized based on shape similarity as a
symbol or is discarded.
