A Quick Introduction to WebP Graphics and Animations

The WebP format was developed by Google as a twenty-first century replacement for the aging hoard of mutant armadillos which has previously served the web as graphic standards. It can be used in place of still image formats, such as JPEG and PNG, and it really gets up and dances when it’s used to replace the medieval relic that is GIF to manage animations.

WebP offers both lossless image compression like PNG and lossy image compression like JPEG. It uses vastly more effective image compression than existed when the foregoing formats were originally created back at the dawn of human civilization, resulting in both smaller animation files and better looking ones. It supports full alpha transparency.

It also handles timing in milliseconds, rather than in the hundredths of a second that GIF uses.

A Digression On Compression

In case the whole lossless and lossy compression issue sounds a bit like two Martians discussing what to order for lunch, here’s a brief digression on the matter.

Graphic files are by their nature sort of huge, and huge files can be a bit of an issue if you have a finite amount of storage space, such as on the SD memory card of a digital camera, or a finite amount of bandwidth over which to transmit said files, such as the Internet if you didn’t spring for a gigabit fiber connection.

They’re easy to avoid in GIF Construction Set Professional, but you’ll need to get them by the throat early in the design of your graphics.

Create Banners with Multiple Animations in Animation Workshop

One of Animation Workshop‘s best tricks is its ability to create conventional GIF animations, such as web page banners, which include multiple independent animated elements. While it’s possible to simply import several animated objects into Animation Workshop and then export a GIF file from them – and hope for the best – you’ll enjoy much more impressive results if you understand what the software is really up to.

Intermediate Files for Animation Wizard

In building animation with GIF Construction Set’s Animation Wizard, you’ll need to create source art as still image files. It’s not immediately obvious which of the formats imported by Animation Wizard will result in the most attractive final animations, and the two most obvious ones – GIF and JPEG – turn out to be the two worst choices.
