Following are the differences between vector and raster graphics-

☛ 1. Raster or Bitmap images are resolution dependent because of this its not possible to increase or decrease their size without sacrificing on image quality.

☛ While vector based image are not dependent on resolution. The size of vector image image can be increased or decreased without affecting image quality.

☛ 2. Raster or bitmap images are always rectangular in shape, Vector image, however, can have any shape.

☛ 3. Unlike raster image, vector image can’t be use for realistic images. This is because vector images are made up of solid color areas and mathematical gradients, so they can’t be used to show continuous tones of a colors in a natural photograph.
