Introduction to Flash
Tuesday, December 30th, 2008While HTML is perfect for creating static websites where all the content is placed at fixed positions Flash is the best tool for creating dynamic sites, where images, texts and animations are moving.
These effects can also be achieved with GIF images or java applets.
Lets compare these two to Flash.
An animated GIF is practically several images saved in one. The browser simply loops these images when the animated GIF is loaded, i.e. if your image has an area that moves in 20 small moves than the animated area is saved 20 times. Thus, it takes ages to load even a small animation.
Besides GIF does not support interactivity and is limited to a 256 color palette.
With Flash you can control your animations. For instance, you can make your animation start when a particular button is clicked. Flash movies load much faster that GIFs and can use more than 256 colors.
Apart from animated GIFs there is another way to achieve dynamic effect - java applets.
Java (the programming language for applets) demands programming skills.
Some programmers created free applets that can be customized though.
Among the most famous ones is the lake applet. It gives a wave effect to any image of any size. But to add anything to the applet you’ll have either to program it yourself or find a ready applet that does the effects you want.
Flash movies are very much alike java applets. They both are small programs that can be put into the HTML pages. But it’s very easy to create movies in Flash without any programming knowledge.
Besides java applets are often programmed so that it takes all the resources of your computer and as a result you’ve got a “freezed” browser.
So, compared to java applets Flash is much easier to create and is more stable in web browsers.
To create Flash movies you have to buy the Flash program developed by Macromedia, the latest version is Flash Mx.
As soon as you’ve installed the Flash program start completing the 8 lessons that come with it.
