I know you can do this by posting your pdf on acrobat.com; unfortunately (from my point of view) I can't use accessibility tools like readoutloud or the commenting tools in this situation. I haven't found a way to use Acrobat 9 pro to do this by itself. Is this a Flash animation effect, I wonder? I have successfully converted a flash animated booklet with this feature that I found online to pdf, though.
on other acrobat user forum there was an answer to similar question.
// Save the settings you plan to change.
var _clickAdvances = app.fs.clickAdvances;
var _defaultTransition = app.fs.defaultTransition;
var _escapeExits = app.fs.escapeExits;
// Change these settings.
app.fs.defaultTransition = "UncoverLeft";
// Now, go into full screen.
// Restore the full screen preferences that you changed.
app.fs.clickAdvances = _clickAdvances;
app.fs.defaultTransition = _defaultTransition;
app.fs.escapeExits = _escapeExits;
The setPageTransitions method accepts three parameters:
nStart — the zero-based index of the beginning page
nEnd — the zero-based index of the last page
aTrans — a page transition array containing three values:
nDuration — the time a page is displayed before automatically changing
cTransition — the name of the transition to be applied
nTransDuration — the duration in seconds of the transition effect
On the last page you can add a button that will close the eBook.
