Authoring Online Interactive Materials in Mathematics

Working with Images

  1. Creating images and animations in a computer algebra system
  2. Adapting photos and other images
    (Note: The links now go to the original full-size images, approximately 135 K bytes each.)
  3. Importing and positioning images

    We show here two sets of revised images. The first row contains images processed in Paint Shop Pro as we did during the presentation. The second row contains images processed in Adobe PhotoShop. The steps in the two programs are not identical -- each has its own set of tools. Notice in particular the Moire pattern in Lang's shirt. This is an artifact of the reduction in size -- you won't see it in the original full-size image. Adobe has a special remove-Moire tool that does not seem to be available in PSP. Feel free to go back to the originals in part 2 and try your hand at processing.

    Each set is displayed in a table without border. While we didn't get around to doing it in the presentation, tables provide the most flexibility in positioning items on an HTML page.

  4. Animated GIFs -- creating and editing
  5. Finding images on the Web

    Fnally, here is the first image that shows up in a search for "manatee" on .gov sites. This time the positioning is done by centering the paragraph.
