Homework due on February 10, 2006

We are almost ready to move on from spreadsheets so it is time to do some reading about our next topic, which is working with photos. We have already done a bit with our yearbook collages, but now we are going to focus on vectors and bitmaps. Although the text starts with bitmaps and then moves to vectors, we are going to start with vectors. So, for Friday please read pages 52-53 and answer the questions on page 53.
