<pre>Description:
If you want to repeat the blinking animation (well, usually just a single blink
is not much useful!) the blinking itself will be very strange, much much faster
of what you would expect and not much usable, because the time the element is
visible is too little compared to the time it's hidden.
Steps to Reproduce:
Let's suppose we want to apply a repeating blinking effect to some element in a
page (not just to a text).
1. Create a new presentation and create some element like a Rectangle or an
Ellipse.
2. Select the element and add the "Emphasis: Blink" effect to it, and set the
Duration of the effect to 1 sec and a Repeat value of 10.
3. Start the presentation (F5) and click to start the animation.
For example, if you set a Duration of 1 sec and a Repeat value of 10, you
would expect 10 blinkings of 1 second each one (so, the animation should last
10 seconds in total). Instead, what you get are 10 strange blinkings (as I said
before, during a single blinking, the time in which the element is visible is
too little) in about 5-6 seconds.
Actual Results:
The total duration of the animation is about 5-6 seconds instead of the 10
seconds you would expect (1sec x 10 repetitions = 10 sec).
And the blinkings look very strange, because the time during which the element
is visible is too little compared to the time it's hidden, so the blinking
animation is not much usable in this way. I don't see other parameters that you
can change to balance the time the blinking element is hidden vs the time the
element is visible.
Expected Results:
You would expect an animation with a total duration of 10 seconds (1sec x 10
repetitions = 10 sec). And you would expect the time the element remains hidden
to be the same of the time the element remains visible. For example, in a
blinking of 1 sec you would expect that for 0.5 sec the element is hidden and
the other 0.5 sec is visible.
Reproducible: Always
User Profile Reset: Yes
OpenGL enabled: Yes
Additional Info:
Bug present on versions: 6.3.6.2 (x64) and 6.4.3.2 (x64). I don't know if it
affects earlier versions too.</pre>
