Unit 30: Task 2 P2

Task 2: P2

The graphical images that will be saved on the Kingswood Website, used on school vehicles and put in brochures will be either a vector graphic or a bitmap graphic. There is a difference between these two graphics. Vector graphics, unlike bitmap graphics are not made up of small blocks of pixels. Instead they made of paths which contain points and curves. This allows the images to be enlarged without a loss of quality. Therefore they are very useful for the creation of logos etc. Common types of vector graphics include Adobe Illustrator, Macromedia Freehand, and EPS files.

Bitmap graphics are made up of dots/pixel squares. These individual coloured squares make up the image that you see on the screen. Therefore if you try to enlarge or zoom in on the image it becomes pixelated and blurred. Common bitmap file types include BMP (the raw bitmap format), JPEG, GIF, PICT, PCX, and TIFF. Therefore for logos the better choice would be to use vector graphics.

For the brochure, either vector of bitmap graphics could be used. The images used will only be of a small scale, so therefore it will not be enlarged and will not become pixelated. To create the brochure you could use publisher with the edited images from software such as Photoshop. On some of the pages, larger images may be required. This would mean that vector graphics would best option, as it means quality will not be lost when the image is enlarged.

For the school website, bitmap graphics would be useful for the smaller images as they are easy files to use e.g. JPEGs. However on some of the web pages, larger images may be wanted so vector graphics would be needed. This is because the bitmap graphics would become pixelated when enlarged which would reduce the quality of the overall website. The vector graphics instead guarantee that the image quality will be good.


The logo on the side of the school vehicle will need to be made up of vector graphics. This is because the logo will be of a big scale, so therefore the file type must stay clear and not become blurry. If bitmap graphics were used, the logo would be very pixelated which looks like a poor quality. This is because the graphics are made up of the individual blocks of colour, and when these are enlarged the blocks become blurry. Therefore vector graphics would be the better choice for the logo on the side of the vehicle.
