Vector Images

• Are a collection of bits that form an image

• Are made up of many individual scalable objects, these objects are defined by mathematical equations rather than pixels.

Bitmap Images

• Are a collection of bits that form an image (pixel based)

• Are made up of many individual scalable objects, these objects are defined by mathematical equations rather than pixels.

What is the advantage of a vector image?

• Images can be scaled up or down with no loss of quality

• Individual pixels can be changed, which makes very detailed editing possible

• They have a large file size

Still images are generated in two (2) ways: bitmap and vector drawn. State the advantage of using bitmap image.

• Easily converted

• Minimal support for transparency

• Easily scalable
