GRAPHICS

Graphics files can be incorporated into a Web page (in-line images) or can be linked to (useful for larger files which may take a prohibitively long time to load). The HTML tag for an in-line image is <img scr="graphics f ile name">.

Besides the obvious use to make Web pages look "pretty", the graphics capability has been essential to communicate mathematics. There are several ways in which I use this capability:

Images of Printed Material

There are times when we wish to place material that is not in electronic form on the Web. This can be accomplished by scanning the material (which can be done at Kinko's, the library, or if our own scanner is operating) to create a graphics file, then accessing that file with a link or as an in-line image. There are some examples of this in the Supplementary Materials section of Math 4410/5410.

Incorporating Mathematical Symbols in Text

HTML does not support a large variety of mathematical symbols at present and since most formatting chores are left to the browser, you can not be sure of how a complicated formula might look to different readers. I get around this problem by incorpora ting my mathematical expressions in graphics in-line images. For one of the many possible examples of this, lets go to the Exam section of Math 4409.

Use of color to convey meaning

The appropriate use of color can add meaning to mathematical exposition. I have found this to be very useful in some circumstances. For instance, lets look at some examples in a special project of mine called Jay's Corner.
