impress.js with fixed top nav not working

I have been working with impress.js, html5 and css. I have got my impress.js presentation to a standard I am quite happy with but I am trying to implement a fixed top nav similar to Twitters.

The current implementation does not work correctly. if you click the bar whilst on a slide/step the links are unclickable.

Convert HTML5 to Flash

I am using impress.js extensively to create a lot of HTML5 presentations. These presentations need to be displayed on touch-screen kiosks. Unfortunately, the vendor handling the kiosks has said that only Flash content can be displayed on these kiosks.

Is there a work-around for this (changing vendor is ruled out, as they control most kiosks here)? How do I convert HTML5 to Flash, without losing the effects my presentations have?

Looking at the source code there is only one image .svg: http://www.inf.usi.ch/faculty/pautasso/talks/2012/soa-cloud-rest-tcc/img/interop-ws2.svg

How can i get this effect with another image?

How to scale transition UILabel without using a lot of memory?

I'm trying to reproduce some of the 2D transitions in Impress.js's sample presentation in Objective C. Specifically the rotate, pan, and scaling - right now I'm focusing on the scaling.

I've tried scaling a UILabel to the point where it "passes the screen", as the "visualize your Big thoughts" -> "and tiny ideas" does in the sample presentation.

This is what I've tried so far:

UILabel *label = [[UILabel alloc] init];

label.text = @"Hello World!";
label.textColor = [UIColor blackColor];
label.font = [UIFont fontWithName:@"Arial" size:18.f];
[label sizeToFit];
label.center = CGPointMake(self.view.bounds.size.width / 2, self.view.bounds.size.height / 2);
[self.view addSubview:label];

label.contentScaleFactor *= 80;

[UIView animateWithDuration:5 animations:^{
    label.transform = CGAffineTransformScale(label.transform, 80, 80);
}];

Unfortunately this eats up about ~30-60 MB of RAM, depending on what the contentScaleFactor and initial font size is. If I don't increase the contentScaleFactor the text looks blurry. Increasing the font size also seems to eat just as much memory.

Here is what it looks in the profiler:

enter image description here

And this is just a single UILabel.

Is there any way to do this without eating up so much memory, without sacrificing quality of the text being rendered or the transitions?

How to make impress.js slideshow auto play and loop

I have a slideshow I'd like to auto play and loop continuously. I've found snippets that let me set a global slide duration and use impress.next() with a setInterval() call to move forward, but then I lose the ability to have different durations for each slide.

See the next screenshot where CSS is disabled but Impress.js is enabled :

And now see the next screenshot where Impress.js and CSS are disabled :

Why are they blurry ?

This is my configuration :

How to use slidify with impress.js

as head of my Rmd-file (impressjs as in https://raw.github.com/ramnathv/slidify/gh-pages/samples/impressjs/index.Rmd) I get an empty directory in libraries/frameworks called impressjs.

Where do I have to enable impress.js? Do I have to install impress.js prior to using it?

How to get a full, seamless rotation with Impress.js?

I'm using impress.js to create a 3D effect in which you are inside four pages, as if they were four walls in a room. To view the next page, a simple -90 degree rotation is used. The pages are already laid out with impress.js using:

//page 1
<div id="title" class="step" data-x="0" data-y="0" data-z="0">

//page 2
<div id="about" class="step" data-x="2000" data-y="0" data-z="2000" data-rotate-y="-90">

//page 3
<div id="our_work" class="step" data-x="0" data-y="0" data-z="4000" data-rotate-y="-180">

//page 4
<div id="contact" class="step" data-x="-2000" data-y="0" data-z="2000" data-rotate-y="-270">

This works, except that the transition from page four to one takes the "long way" around. As in, the rotation is displayed as a 270 degree rotation instead of -90 as the others. If I change page 1 rotation to -360 to solve this, transition from page one to page two is broken. How would I go about making a full circle of transitions?
