YouView is a Smart TV service in the UK, a spin-off of a BBC RnD project which runs on Set Top Boxes and certain Smart TVs. I worked on the core UI for years and thought I’d share some insights into best practices when building applications for such resource constrained devices.
A common oversight in Flash projects, when using a Bitmap with loaded content is that Flash will revert a Bitmap’s smoothing parameter to false when you replace its bitmapData. That is, when the data loads into the Bitmap, anti-aliasing will get turned off. This is simple enough to fix, but since you may not know if someone is going to replace the bitmapData of a Bitmap you have created – then it’s much better to code defensively for it.
This little SmoothBitmap class is for just such an occasion. Instantiate it like a regular Bitmap and, no matter what another developer does with it, smooth, anti aliased pixels when scaling/rotating will be ensured. Enjoy 🙂
I was recently creating an API that required extending TextField and happened across the getRawText() method. I assumed this returned the text from the field without formatting or something – so I looked up the AS3 docs for flash.text.TextField.
Nothing there – gee thanks Adobe. A quick search turned up this which, it turns out, isn’t quite accurate.
So, with a tad of testing, it appears that getRawText() returns the text, stripped of any HTML tags (if you had set htmlText). I now wonder if this is faster than using a RegEx to strip the tags and why Adobe didn’t document it?
