What are Bitmap Graphics?
Topic 5
A Bitmap graphic is when you take a photograph using a digital camera or scan an image from a magazine in which you are creating an Bitmap graphic.
Bitmap graphic consists of many tiny parts called pixels. They can be in different colours, However it is in fact impossible to edit each individual pixel.
The file of a Bitmap graphic is often quite large. The computer stores information about every single pixel in the image. when you change the size of a Bitmap image, it often loses the quality of the image itself.

Advantages & Disadvantages of a Bitmap Graphic...
Disadvantages:
Advantages:
Advantages:
- Not upward scalable will not be able to make the Bitmap image large as the picture will be pixelated and make the image harder to recognize.
- They require higher resolution.
- Vector images are scalable- co you can change the scale of the image and the quality of the image remains the same instead of pixelated.
- Each set of lines in the vector image represents seperate distinct objects which means they can be edited individually at any time
- Vector images are smaller than a bitmap image and saves you memory.
Disadvantages:
- Easy to create- Take a photograph with you camera or scan one in.
- simple to output depending on your printer memory.
- cost effective
- can be recoloured and identified easy as the colour pixels are solid.
- You can only scale up to about 20% larger or smaller than the image itself
- Thin lines may appear if the vector image is reduced too much
- Takes a lot more time and talent to create a vector and they are often made on adobe illustrator
- Not as cost effective as bitmap images
What is Vector graphics?
Vector graphics is created in graphics packages and are made up of shapes called objects. It is impossible to edit each object such as; the shape, colour, size and position.
The file size of a vector image is often quite small. If an object in a vector image is large, then it doesn't need a lot of computer memory. The vector images are scalable in which it can be resided and will not lose its picture quality.
