2. This report will tell you what digital graphics are, and how this relates to
producing graphics and images for games. Digital graphics are images and or
texted notes created on a computer. Because it can be created on a computer
you can edit the image like crazy; you can add colour tints to the image, add
effects and hundreds of other things.

3. Bitmap images are images that are made up of different colour pixels. Bitmap images can be
made by either taking a photo on a camera or scanning a image from a magazine. Bitmap
images are usually used in old arcade games such as Sonic and Mario. Some common file
extensions are .Jpeg, .GIF, .BMP.
Unlike Vector graphics when a Bitmap graphic image gets enlarged it tends to lose its
quality. Like the example below. A few programmes that create bitmap images are Adobe
Firework, MS Paint and CS Photoshop.
Advantages
- Bitmap images are very easy to create. All it takes is to take a picture or scan something in then you have one.
- Doesn’t cost anything.
- A bitmap image uses solid color pixels, which can be identified and recolored easily.
Disadvantages
- A disadvantage of a bitmap image is that they require higher resolutions and anti-aliasing for a smooth appearance.
- The .bmp file has been created by Microsoft and ibm (International business machines) and is consequently they’re harshly bound to the
construction of the main hardware platform that both companies support.
Normal.
Zoomed in.
The 2 images on the right shows the same picture
but I’ve zoomed In to show you how the pixel
become much more visual as you get closer into
detail.
The first picture is in high quality but no matter
how good the quality is, once you’ve gotten closer
to the image it vastly changes to a retro game
visual style.

4. Vector graphics are made up of points, lines, curves, and shapes or polygon, which are all based on mathematical
expressions, to represent images in computer graphics and gaming.
Also the graphics are created in packages, for example you can use certain programmes to make vector graphic
photo; Some sort of imaging software like CS Photoshop or MS Paint.
Advantages
- Vector graphics can easily represent simple geometric objects, in file sizes that are far smaller
and faster to operate on.
- The objects used in a vector graphic can be resized and repositioned after they have been
created. The entire vector graphic can be resized to any dimensions without losing any
information.
Disadvantages
-Drawings containing trapping information can only be scaled up to 20% larger or smaller. Thin
lines may disappear if a vector drawing is reduced too much.
- Small errors in a drawing may become visible as soon as it is enlarged too much.
Here is an example of how vector graphics work.
Common vector file formats
Adobe Illustrator – AI
CORELDraw – CDR
ShockWave Flash – SWF
Scaleable Vector graphics - SVG
Windows Metafiles - WMF

5. Capturing images
Drawing into a sketch pad.
ADVANTAGE
If your good at drawing you could do it to make it feel real.
Easily edited to make for quicker development.
DISADVANTAGE
It takes some getting used to.
Once you get used to it, it still might take a while because mistakes are quite easy to make when using a sketchpad.
Scanning an image.
ADVANTAGE
