What is raster bad for?

Disadvantages of raster graphics: If you do try to enlarge a raster image, it will look grainy and distorted. When you increase the size of a raster image, the image increases in size however, because there are no longer enough pixels to fill in this larger space, gaps are created between the pixels in the image.

What are the advantages and disadvantages of bitmap images?

In terms of the amount of digital storage, bitmaps are memory intensive, and the higher the resolution, the larger the file size. The other disadvantage with bitmaps is when an image is enlarged, the individual coloured squares become visible and the illusion of a smooth image is lost to the viewer.
