LESSON 31: PIXELS AND MORE

1. Study the index cards on Pixels and Resolution. I've included a hard copy of these index cards, for your convenience.
   You'll need a ruler for this lesson. You can print out a paper one at this site:

   2. What is a pixel?
   3. When a graphics monitor is reported as being "1024 by 768," what do these numbers mean?
   4. What is "resolution"?
   5. Is resolution measured in different ways for different devices?
   6. What are two types of devices that would report their "resolution"?
   7. How is "monitor resolution" usually stated?

   12. What two things determine what the length of a 100 pixel line will look like, for a given individual?
   13. Suppose an individual has a monitor that is 11.2 inches wide, and measures 1024 pixels across. How long will a 100 pixel line appear in this situation? (SHOW ALL WORK LEADING TO YOUR ANSWER!)
   14. Suppose that Bob's screen area is 17 inches across. His monitor resolution is 800×600. How long will the 100-pixel line appear on his machine?
3. Finish reading Chapter 11 in the Weasel book, pages 154 to 163. You already know a lot of this material, since you've just finished a week working on imagemaps! However, there's some new information in this reading.

   5. Name two full-featured WYSIWYG web authoring tools that have imagemap creation tools built in.
   6. Describe very briefly how an imagemap-creation tool works; what does it do FOR you that saves your time and energy?
   7. What is one way to get the functionality of an imagemap, without actually using an imagemap?

   9. What is one advantage to a "simulated imagemap using a table," with regards to users who cannot view graphics?

   16. Can the "mailto:" link also be used to fill in the "Subject" field, the "CC" field, the "BCC" field, and BODY text in the email?
   17. Write the code that would say "Send Carol email!" and would open up an email tool with the email address "carol@hotmail.com" already in place; it should have "reporting a bug" in the SUBJECT line; it should have "webguru@hotmail.com" in the CC line.
   18. If you're using a "mailto:" link and want a space character in some subject code, how must you code this space character?
