Common examples are JPG, PNG, GIF, TIFF or BMP. Raster images are the default output digital cameras to most graphics editing software like Paint or Paintbrush. They are made up of pixels, which is to say a grid of colored rectangular dots. The advantage of raster graphics is that at high resolutions

The advantage of raster graphics is that at high resolutions (lots of pixels in a small area) you can have very fine control over color and shape; raster images can contain millions of colors

e Page 2 1.2. Raster Image Formats There are two main kinds of graphics: raster graphics and vector graphics. Raster (or bitmap) graphics is to represent graphics into small rectangular rectangular points called pixels. Raster graphics is suitable to store digital photos. In contrast, vector graphics is to represent graphics into geometric objects like lines, curves, polygon, etc. These can be enlarged without any loss of quality and is therefore useful in visual designs. Common raster image formats are listed below: Extension Name Properties BMP Windows Bitmap Accepted
