- GIF
-
The simplest and most widespread on-line image is probably the GIF. It was the first web image format to take off, and has been extended to handle simple movies as well as static images.
- Image Editors
- While Photoshop is probably the most well-known image editor, it’s heavy overkill for most web uses. There are a lot of free and low-priced alternatives that work great for web graphics.
- Images on the Web
-
Discussion of image formats for the web, with a focus on jpeg, gif, png, and QuickTime. These are the major image formats that you will use for web images.
- JPEG
-
When it comes to photographs, the JPEG is almost always the best choice for on-line graphics.
- PNG
-
For a long time, the PNG format wasn’t widely supported. You can safely use it today, however, and it works great just about everywhere that a GIF could be used.
- Pushing the Envelope
- What can the infobahn of today give us now?
- Quicktime
- Quicktime, in my experience, is by far the best choice for distributing movies and animations.
- Reducing File Size
- File size and image quality is always a trade-off. Your goal will be to get the appropriate quality while keeping download times fast.
- Text logo with a super-imposed image
-
Use constructive solid geometry and image maps to create a text logo from photographs or other images.
- Why text?
- Why the text interface to Persistence of Vision is extremely important.
