Two types of computer graphics
bitmapThe term bitmap comes from the computer programming terminology, meaning just a map of bits, a spatially mapped array of bits.
bitmapBitmap graphics describe images using colored dots called Pixels, arranged within a grid.
BitmapBitmap graphics are Resolution-dependent because the data describing the image is fixed to a grid of a particular size.
BitmapA bitmap image uses a grid of individual pixels where each pixel can be a different color or shade.Bitmap image is also known as Raster Image
vectorVector graphics describe images using lines and curves, called Vectors that also include color and position properties
vectorVector graphics are Resolution-independent meaning they can be displayed on output devices of varying resolutions without losing any quality
vectorVector graphics are composed of Paths (Lines and curves).
Bitmap vs. vectorThere are instances when both formats come together. An understanding of the advantage and limitations of each technology and the relationship between them is most likely to result in efficient and effective use if tools.
Bitmap vs. vectorThe jagged appearance of bitmap images can be partially overcome with the use of anti-aliasing. Anti-aliasing is the application of subtle transitions in the pixels along the edges of the images to minimize the jagged effect.
Bitmap vs. vectorBitmaps are best used for photographs and images with subtle shading. Graphics are best suited for the vector format are page layout, type, line art or illustrations.
