If you want to the exported SWF performs just like the original
PowerPoint, you got a long way to go. Be patient
First, you'll need to prepare the PowerPoint document. Make sure you
are not using any complicated gradients or animations. These will be
interpreted poorly when they are brought into Flash. Also, make sure
there are no objects that fall outside the confines of the slide area.
This will ensure that all the slides align correctly when they are
imported to Flash. Now, save a copy of your presentation without any
background images. You may want to also choose a contrasting background
color to easily see the content of each slide. You all import the
background images into Flash at a later time.
Second, choose File > Save As... from your PowerPoint document and save
the presentation as a Windows Metafile (*.wmf). This will save your
entire presentation as a sequence of files. WMF files keep all text.
Next, create a new Flash Document and resize the Stage to 720 x 540.
Change the background color to black. Choose File > Import > Import to
Stage... and import the first WMF file. When asked to import all of the
images in the sequence, choose Yes. This will place each slide from
your presentation onto a sequence of frames.
Then, create a new layer under the slides layer and import the images
to use for your background. You'll probably need two images, one for
title slides and one for the regular slides.
Now it's time for some manual labor. You'll need to go through every
frame of the movie and delete the solid background shape from your
slides layer. Once this is complete, you should see the content of each
slide with the correct background image behind it.
Finally, add a frame to the end of your movie. Place some static text
on that frame that says something like "End of slideshow, click to
exit."
Alright, now it's time to move on to some ActionScript. Create a new
layer for your actions. There are a few statements you'll need
to include right away. First, you want this movie to play full screen
so add an fscommand.
fscommand("fullscreen","true");To make sure the Stage resizes correctly
specify the scaleMode.
Stage.scaleMode = "exactFit";Finally, you don't want the movie to begin
playing through all the slides right away before the user starts
clicking, so add a stop function.
stop();You'll need to include some functions that will be used
frequently to navigate the presentation.
function gotoNextSlide():Void {
if (_currentframe < _totalframes) {
gotoAndStop(_currentframe + 1);
} else {
quit();
}
}
function gotoPreviousSlide():Void {
gotoAndStop(_currentframe - 1);
}
function gotoHome():Void {
gotoAndStop(1);
}
function gotoEnd():Void {
if (_currentframe < _totalframes) {
gotoAndStop(_totalframes - 1);
}
}
function quit():Void {
fscommand("quit");
}Next, we need to handle all the keyboard and mouse events so that the
user can navigate through the slides. We'll do this by creating a new
listener object.
var myListener:Object = new Object();
myListener.onKeyDown = myOnKeyDown;
myListener.onKeyUp = myOnKeyUp;
Key.addListener(myListener);
myListener.onMouseUp = myOnMouseUp;
Mouse.addListener(myListener);Here are the listener functions.
function myOnKeyDown():Void {
if (Key.isDown(Key.DOWN) || Key.isDown(Key.PGDN)) {
gotoNextSlide();
} else if (Key.isDown(Key.UP) || Key.isDown(Key.PGUP)) {
gotoPreviousSlide();
} else if (Key.isDown(Key.END)) {
gotoEnd();
} else if (Key.isDown(Key.HOME)) {
gotoHome();
}
}
function myOnKeyUp():Void {
if (Key.getCode() == 27) {
quit();
}
}
function myOnMouseUp():Void {
gotoNextSlide();
}
If that's too complicate to you, you can try some PPT to SWF software,
like SameShow ,MelodyPPT,Arbicate etc, all of them
can help you convert PowerPoint to Flash with cool effects
