Raster to Vector Conversion
A raster object is a graphic comprised of an array of pixels, or colored grid, with each element assigned a color. Raster objects are often referred to as bitmaps. The conversion of raster objects to vector objects is also referred to as vectorization and involves the conversion of groups of pixels into points, lines, curves and polygons (filled shapes). Raster to vector conversion is used in the process of scanning and converting blueprints to CAD models.
