AUTO VECTORIZATIONon September 1, 2012 at 8:54 am
Auto-vectorization software automatically converts raster images into vector files. In other words, these tools can convert a scanned image (a raster or bitmap, such as. a tif file) of a drawing into an editable CAD file (e.g. a dwg file). While auto-vectorization software continues to improve, it’s usually a good idea to go through the output to clean up stray errors. Also, auto-vectorisation software does not automatically put different elements of the drawing (e.g. text) in separate layers.
Auto-vectorization software is used in the areas of CAD, GIS, graphic design and photography:
- In computer-aided design (CAD) drawings (blueprints etc.) are scanned,auto–vectorized and written as CAD files.
- In geographic information systems (GIS) satellite or aerial images areauto–vectorized to create maps.
- In graphic design and photography, graphics can be auto–vectorised for easier usage and resizing.
Many different algorithms exist to automate the conversion of raster images into vector images, and each gives varying results. DesignPresentation utilizes several different software tools, and selects the right software for each situation. Some drawings are beyond the scope of any of the auto–vectorisation tools currently available, and have to be re-drawn from scratch.
