What does bitmap mean Bitmap?
Vector and bitmap are both image files. Bitmapped images are
images that are stored on a pixel by pixel basis and because of
this, when you enlarge the image it can appear blocky. A vector
image is constructed from dots, lines, shapes, etc. Each part has a
particular position within the image with it's own dimensions.
Because vector images are constructed using images, they can be
enlarged without loss of image quality. Vector images do not get
the blocky appearance of an enlarged bitmap image.
