Creating a mathematical colour picker

The most common technique for creating a colour picker (at least in the ActionScript world) seems to use a colour wheel bitmap and then getting the colour of the pixel that was clicked on. I found that this was not a very accurate way to go about it and decided to build a colour picker […]

Reverse engineering Captivate for HTML5 widgets

Adobe Captivate is pretty horrible, especially the HTML5 output. I feel like I’m banging my head against a wall every time I use it. The HTML5 output is riddled with bugs and most of the features simply don’t work. If there is one upside to the HTML5 publishing though (and there aren’t many), it’s the […]

This post has been sitting around unfinished since April so I thought I should finish it and get it out there. In this post I am going to show how you can capture an image from a webcam via JavaScript and convert it to a Data URI which can then be saved in a database […]

Creating HTML5 widgets for Adobe Captivate 6/7

I decided to write this post due to the frustration and lack of information out there on how to make HTML5 widgets for Adobe Captivate.

AS3 / JS Constrain a value in one line

Here is a little snippet to constrain a value in a single line. It works by using two nested inline conditionals. The ‘else’ part of the first conditional is another conditional.

JS Transform Handles

The other day I was playing around with Mozilla’s Popcorn Maker and I had the idea of using HTML/JS/CSS to create transformable divs using transform handles and a bounding box. I did a quick search for any existing examples of HTML transform handles but i couldn’t find anything so I decided to give it a […]

Adding console.log() to AIR’s HTMLLoader

Here is a little code snipped I thought I’d post for future reference and may help someone else out. I was using the HTMLLoader class in Adobe AIR to load content and I came across an error where my Javascript was calling console.log(). In the AIR HTMLLoader environment this function does not exist so I […]

A simple way to get native alerts with Adobe AIR

In an AIR project I am currently working on I wanted to have native alert boxes in my app rather than building custom pop up boxes. There is no built in way to get native alerts in AIR and I remembered reading this interview over at leebrimelow.com a while back where a developer at Illume used StageWebView […]
