![]() ![]() On enlarging a vector image, mathematical formulas remain the same, scalable to any size. Enlarging file with increasing in pixel count, which may produce better results comparatively. On enlarging a raster image without a change in pixel count, the image looks blurry. Similar to creating an image with different tiles of different shapes and sizes. When the user paints a vector image, only the outline of the shape is painted. When the user paints a raster image, it looks similar to dipping brush in paint and painting images. Vector images are much more scalable than Raster images. Raster images have a wide range of colour gradations and less scalable than Vector images. Vectors are small files that contain information on Bezier curves that form the drawing. Raster has simple output, as long as RIP or printer has required memory. The last two are created by CAD and GIS applications. Vector formats include EPS, PICT, WMF, PostScript, TrueType. Graphic Raster formats include JPEG, GIF, PNG, XBM, TIFF, PCX, and bitmap fonts. Vectors use mathematical formulas in describing colours, shapes, and placement. With an increase in complexity, it can contain more colours. Raster has only two colours, black or white. The vector consists of instructions on where to place its components. Raster image knows the colour of each pixel. Each vector element has its own coordinates and can be resized. Vector images are collections of elements such as lines, rectangles, circles, and square. In Raster, pixels of the same colour or different colour are placed close to each other so that the human eye perceives them as pictures but not as dots. Vector images are made up of lines, fills, and curves. Raster images are also known as Bitmap images and are made up of small dots known as pixels. The table below summarizes the comparisons between Raster vs Vector : Raster
