While putting together last week's promo video for Museum140 (a vote'd be awsm, btw), I knocked up a few tools to make my life easier. As I always say, if you find something you like, make a plugin for it. Seriously, I always say that. That might even be how I proposed to my wife, I'll have to check.
This is a simple timing helper. It just provides a little array you can push slide durations into and at the end, you call 'play'. I can't see many uses for this other than in creating videos.
ImpressJS.play(3000); //Set the first slide duration for 3 seconds ImpressJS.play(1000); //Set the second slide duration for 1 second ImpressJS.play(); //Play from the start
This is much more useful.
If this script is included in the page (after the impress.js script), you can drag your slides around, rotate and scale them into exactly the position you want. Once you're happy, you can get the current HTML output onto the console for pasting back into your original slideshow file. I could have snuck in a drag-n-drop file handler but that would make it Chrome only.
These tools rely on ImpressJS having a public API which it currently doesn't have. It's obviously high on the author's priority list (given the amount of discussion it's raised) but, as too many pull requests spoil the broth, I've made a little fork of my own, added the public functions the tools require and I'll update them once the main repository's settled down a bit.
These are available in the tools folder of this fork of impress.js. Each one contains an example. Hopefully, these will be updated to use the public API as soon as it's available.
