Bitmap

A bitmap is an image that is composed of a great amount of small squares, these small squares are called pixels, and you can get pixels in almost any colour thinkable. When you resize bitmap images it causes the image to loose quality, this is called ‘pixelated’ if you zoom in enough you will eventually start to see each individual pixel. Putting bitmap images on brochures and leaflets would be best, this is because they are very detailed, but when you put the image on the leaflet/ brochure, you should make sure the images are the original size or shrunk so they don’t pixelate and remain keeping their professional look. Examples of bitmap files are GIF, PNG, BMP and JPEG.

Vector

You create vector graphics in graphic packages, they are made up from shapes and objects, a benefit of making a vector graphic is that it’s a graphic and you are able to edit each object separately, you are able to change the colour, size, shape and position of each object. Another benefit is that you are able to make your graphic whatever size you want without it pixelating or losing any quality at all, and also these graphics take only a very small amount of computer memory. I think due to being able to make the graphic any size you want I think the vector graphic would be suitable for putting on vehicles as they would need a large image. Examples of vector graphics are AI, XAR FS and AWG.

PDF (Portable Document Format)

A PDF is a mixture of bitmap and vector images, but with these images, unlike printed documents, you can include links, audio, video, and images on your document, for this reason the PDF should be used on the website as it has many features in which you can use on the website.
