  1. Creating Web Documents Frames Image Maps Ethical/Legal issues Homework: Make a reply posting on at least one issue

  2. Frames • Way to divide a page into distinct windows, generally to ease navigation. For example, • maintaining a ‘table of contents’ on the page • creating consistency across pages of a site • maintaining banner/logo

  3. Frameset • In place of the body tags: <frameset cols=“200, *”> <frame src=“toc.html”> <frame name=“contents” src=“welcome.html”> </frameset> • Creates two frames, the first one taking up a column of width 200 pixels. The second whatever is left. • Each frame gets an initial HTML file. The second frame has a name, which can be used to target links, from the toc page <a href=“story.html” target=“contents”>Stories </a>

  4. Experiments • First, create 2 ‘regular’ HTML files. (Eventually you will have 4.) Call them welcome.html & more.html • Create a 3rd HTML file and call it main.html <html> <head><title>Frame test </title> </head> <frameset cols=“200, *”> <frame src=“toc.html”> <frame name=“contents” src=“welcome.html”> </frameset> </html> • OR change to rows, change widths/heights

  5. Experiment, continued • Create the toc.htm file <html> <head><title>Table of contents</title></head> <body> Topics <p> <a href=“welcome.html” target=“contents”>Welcome </a> <p> <a href=“more.html” target=“contents”>More </a> <p> <a href=“http://www.purchase.edu” target=“contents”>Purchase</a> </body> </html>

  6. Experiment, cont. • main.html • Has the frameset tags, sets up the frame. This will be what is shown when you view page source. Mentions toc.htm and welcome.htm • toc.html • Source of leftmost frame. Mentions welcome.htm and most.htm • welcome.html • Initial source of rightmost frame • most.html • Will be placed in rightmost frame as result of hyperlink in toc.htm

  7. Files html files • main, toc, plus • welcome plus alternatives Image files

  8. Experiment, continued • Make sure all 4 files (plus any images if your files refer to images) are in the same folder. • Go to Netscape or IE and open main.html • Check links. • Now, change the links (one at a time) in toc.htm or in welcome.html: • Make one of the target=“_blank” • Remove a target

  9. Frames • Advantages? • Disadvantages?

  10. Image map • Way to have parts of image be different links. • Best if meaningful! • Image map: designate parts of image • We will do ‘client side image maps’. Image maps can also be implemented on the server. • Image slicing (done using Photo Shop): takes image apart and re-constructs it as a table. Makes the individual items in the table links.

  11. Example http://zephyr.ns.purchase.edu/math/new_media/pepsi/design/mapexample.html http://csis.pace.edu/grendel/materials/map.htm Many other examples Band web site: image map identified members of the band Trip: image map for (geographical) map Diagram: click on parts for more information

  12. Image map • Need to specify that image does use an image map • Need to specify the portion of the image for each action • Specify shape (rectangle, circle or polygon) and parameters for that shape • Need to specify the href to be taken • Link can be internal to document (#place) or on same server or anywhere on web (http://...) • May choose to make the portion of image an image where the link is. (see two examples: Ohring family and Winter Dinner).

  13. <img src="diagram.jpg" usemap="#mymap"> <map name="mymap"> <area shape="rect" coords="200,300,400,450" href="detail1.html"> <area shape="circle" coords="500,650,100" href="#place"> <area shape="polygon" coords="50,100, 60,150, 3, 150" href="detail3.html"> </map>

  14. Coordinates? • Obtain coordinates in Photo Shop or Paint Shop Pro • Note: pixel units are very small, so you will probably not get the exact same results if you repeat the process.

  15. Exercise • Find an image • Go into Photo Shop or Paint Shop Pro and write down coordinates for 2 rectangles • Write HTML for image map. Make any 2 destinations: www.purchase.edu; www.nytimes.com • Try again: do circle and polygon region.

  16. Ethical/Legal issues • Intellectual property (on the Web) • Music file sharing • Government programs • Privacy • Other?

  17. Project II • Topic of your choosing (but I need to approve) • Definite purpose and audience • Mostly your own writing and images • "Fair use" • Propose on Blackboard. I will approve or suggest alternative on line. • Required elements: • At least 3 html pages • tables, • frames, • image map or image slicing or animation

  18. Homework • Make reply posting to Discussion Forum on ethical/legal issues involving the Web. • This could be your Project II topic. • Continue participating (make postings: new threads and replies) • Read HTML text on Frames. • Next class will be Animation Shop. Image Maps. Image slicing. • Instruction will go on in class as you are working on your projects.
