Creating a basic animated GIF using the graphical tools of FrontPage
98
The careful use of animation on your web site can quickly get
the attention of visitors. The easiest way to bring animation to your site is to
use animated GIFs. Like standard GIF images, they can be viewed in virtually all
web browsers.
Thoughtfully, FrontPage 98 is supplied with two tools -
Microsoft Image Composer and GIF Animator, that make it possible to create web
animations. Neither are mentioned to any degree in the FrontPage manual, but the
following tutorial will provide you with some assistance in creating your first
animation.
There are two parts to creating a web animation. The first is
to create some animation frames. You can create these in any package, but the
Image Composer Button Wizard is particularly well suited to producing some
frames
In this example, the Button Wizard will be used to create two
identical buttons (shown below).
The first image (with the red text) was produced
by creating a standard button (using the Bottlecap style and Cool
Steel fill). After creating the button, it was ungrouped by selecting
it and using the menu command Arrange|Ungroup*. The button and
its associated New Products text label were then resized so
that the button was slightly larger than the text object. Finally, the red text
was given a small, white drop-shadow by selecting the text and using the Drop
Shadow effect (accessible in the Effects palette).
* When you have used this command, be aware that
you can no longer edit the button's properties in the Button Wizard.
The button with the purple New Products
text was created by selecting the original button, then using the menu command Edit|Copy
followed by Edit|Paste to create a replica of the button. The
text of this second button was then highlighted and its hue altered to a purple
color by entering -90 into the Hue field of
the Color Tuning palette.
These two buttons were then used as the basis for
an animated web graphic.Start Microsoft GIF Animator by using the Image Composer
menu command Tools|Microsoft GIF Animator (or look for it under
the Microsoft Image Composer part of the Windows 95/98/NT Start
menu).
The first process in using GIF Animator is to
import the animation frames into the program. This is easily accomplished by
highlighting the button in Image Composer and using the menu command Edit|Copy.
In GIF Animator use the Paste button to paste a copy of
the button into it. Repeat this process for the second button. You should then
see that your new animation has two frames. You can preview the animation by
using the Preview button.
The first time you preview the animation you will
see that it will play just once, then stop. To make an animation loop, click on
the Animation click-tab and ensure that the Looping
check box is ticked. Also tick the Repeat Forever check box if
you would like the animation to continue indefinitely. Alternatively, enter a
number in the Repeat Count field if you would only like the
animation to loop a certain number of times. This is useful for animations that
would otherwise prove too distracting for people reading the page.
If you preview the animation again, it will loop
the requested number of times, but the animation will loop very quickly between
the two animation frames. It is, therefore, a good idea to slow down the
animation's frame rate. Do this by clicking on the Image
click-tab, then using the Select All button in the toolbar
to select both animation frames. Enter a new number in the Duration (1/100s)
field - 90 is a good figure for an animation with two frames.
Preview the animation again if you would like to check the speed of this new
frame rate.
If your web page uses a patterned background then
you might need to make your animation's background transparent. This can be
achieved by using the Select All button in the toolbar to
select both animation frames, ensuring that the Transparency
check box is ticked, then selecting the color to make transparent in the Global
Palette window (accessible by clicking on the Transparent Color).
The Preview window will show transparent animations as having a
gray background.
Once you have done this, you can save your
animation and incorporate it into a web page using the same procedure used with
any other image. The final animation is shown below:
