Raster Graphics (Bitmap)
A data structure which represents a rectangular grid of pixels, they are characterized by the dimensions of the image in pixels as well as by bits per pixel.
Raster graphics are more commonly used for photo realistic images than their vector counterparts as they allow for much more complex images to be displayed. This is because they are composed of several small pixels of colour that combine to form the image.
Advantages:
· Image refresh rate is independent of the image’s complexity.
· Faster refresh rate as less processing power is required to render the image.
· Realistic images can be displayed due to high resolutions
· The location of each pixel is implied by its position in the image, meaning that only the origin point has a coordinate stored.
Disadvantages:
· Cannot be upscaled due to rapid loss of quality.
· They require higher resolution and anti aliasing for a smooth appearance.
