ISWD24: JavaScript V

Cookies can be used to remember information about a visitor until their next visit to the site, and to pass variables between pages.

ISWD23: JavaScript IV

Alerts and Dialogs can be used to get the user's attention and to solicit input. The input can alter the behavior of the page.

ISWD22: JavaScript III

In this class we look at how to add rollovers using JavaScript.

ISWD21: JavaScript II

This class provides an introduction to the JavaScript scripting language, that can be used to add functionality to web pages.

ISWD20: JavaScript I

This class illustrates how tables can be used to code more complex web pages.

ISWD19: Designing with Tables

In this class we look at how the MPEG standard codes digital video.

ISWD18: Digital Video Compression

JPEG was designed as a general purpose ISO standard for photographs. In this class we look at the compression techniques employed by JPEG and how they affect its usefulness.

ISWD17: Joint Photographic Experts Group (JPEG)

In this class we see how dithering can simulate the effect of an unavailable color by clever juxtaposition of available colors.

ISWD15: Image Compression - Dithering

In this class we look at how subsmapling can reduce the size of imagee files. Subsampling reduces the amount of information in an image by throwing some if it away. This is simple but effective.

ISWD14: Image Compression - Subsampling

In this class we see how HTML uses the RGB system to the specify color of text and backgrounds.

ISWD13: Adding Color to Web Pages

In this class we continue our look at how color can be represented digitally. The Red Green Blue (RGB) color system is used by most computer systems. The Cyan Magenta Yellow Black (CMYK) system is used by the printing industry.

ISWD12: Digital Color - Part II

Although we deal with color every day, we rarely have to put numbers on it. In this class we look at how color can be represented numerically using the Hue, Saturation, Brightness (HSB) system.

ISWD11: Digital Color - Part I

In this class we look at how a black and white image could be stored digitally.

ISWD10: Digital Images

In this class we look at how everyday analog values are assigned digital representations. Using temperature as an example, we introduce the copcepts of quantization, resolution, and sampling.

ISWD09: Digitization
