Week 8 Raster vs Vector Images

This week we are looking at the difference and application of Raster (Bitmap) and Vector Images when creating computer graphics.

Our Aims are:

To Understand the difference between vector and raster graphics

To Understand the importance of resolution when dealing with document set up and screen settings

To be aware of the different 'Aspect Ratios' for screen applications and designs and how to set them up correctly

Here is the board-blast from todays session for your reference

This video will reinforce much of the seminar content from todays session watch it back before trying the blog tasks bellow:



Blog Tasks:

1. Please provide in your OWN words a paragraph review and definition of the difference between a Raster graphic (and its likely use) against a Vector Graphic (and its likely use)

Provide links to images and sites which support your points etc (otherwise known as a case study)

2. In the session I told you that one of the screen resolutions which conform to a 4:3 aspect ratio was 1024x768. In your blogs please explain what an aspect ratio is and provide a screen resolution that conforms to an aspect ratio of 16:9

Again use links comments and other sources to help make your points

These tasks should be completed by next weeks session. (failure to comply will result in Shaun's sad face and none of us wants that right??)
