Quality of bitmaps is given for every one size of the photo. If we extend the photo, quality go down. By contrast we can to extend vector picture “without end” and sharpness is same. To make a high-quality bitmap is absolutely petty - good-class digital camera is enough. But to make a good vector picture is more complicated and is needing a lot of gift and imagination. Everybody can to take a photo, but to draw can who can only.
