Web Site Building · Integrating Graphics
What this is about:
There are a number of ways to manage your web page layout including tables, forms, and frames. There are also tools for adding interactivity to your site. One of those tools is Dynamic HTML, or DHTML. It is not something that can easily be described, or separated from other web technologies. It is a group of technologies that, when tied together, enable a developer to bring a page to life. The three main components that make up DHTML are HTML, JavaScript and Cascading Style Sheets (CSS). HTML is used for the basic structure of the document, JavaScript to manipulate the Document Object Model (DOM), and CSS to define the presentation and style of the document.
Graphics Helpware Tips and Samples
Basic Formatting — Imagery on the World Wide Web
takes on many shapes, sizes, colors, formats and compressions. File formats
are standardized means of organizing and storing images. Image files are composed
of either pixel or vector data that are rasterized to pixels when
displayed in a vector graphic display. The pixels that compose an image are
ordered as a grid in columns and rows; each pixel consists of numbers representing
magnitudes of brightness and color. Chief among these digital image formats
are the popular JPG, GIF and PNG graphics files. In this tip learn the differences
between them, and how to add transparency to your images.
Simple Animation — Another clever gimic built-in to GIF imagery is the ability to combine multiple images into one file producing animation. An animated GIF file comprises a number of images or frames to be displayed successively, each described by its own GCE (Graphic Control Extension), preceded by a header whose content applies to all the frames. After the header the data is stream-oriented instead of being at fixed indices, so the location of the start of a GCE depends on the length of preceding GCEs.

Layering Techniques — A guest article from Robyn A. Harton, designer and developer of Robyn A. Harton Creative. Using layers makes it so much easier to edit graphics. Objects on separate layers are simple to move, recolor, select for filtering, and texturing. You can also get a huge number of interesting effects by using transparency and blend modes on a layer. Layered images are sometimes called 2 ½-D computer graphics. They make it possible to mimic traditional drafting and printing techniques based on film and paper, such as cutting and pasting; and allow the user to edit any layer without affecting the others. For these reasons, they are used in most graphics editors. Layered images also allow better anti-aliasing of complex drawings.
