Difference between Raster and Vector files?
• A raster image is a drawings photograph. If you look closely you see that it is made up of lots of small dots. The density of these dots is referred to by resolution, measured in dots per inch (stated as ‘dpi’). The more the density of dots, i.e. greater the “dpi” clearer will be the image. Raster files are stored in many file formats, e.g. TIFF, GIF, RLC. • Vectors are used to describe specific objects defining their size, position and geometry. The image seen on screen in a CAD application is only a visual representation of the vector data. The vector information in a CAD file is mathematical. It is not stored as an image. • Vector information is stored in many different file formats, one of which is DXF. The primary function of the DXF file is to permit CAD vector information to be exchanged between different CAD applications.
