Great stuff, thanks for sharing!

Re: Normalizing Angles

Dmitry — Tue, 20 Mar 2012 01:27:13 -0000

That will normalize to [-360...360] (or [-2Pi...2Pi]), i.e. 720-degree sweep. So, you'll have to add 360/2Pi and normalize again:
((angle % 360) + 360) % 360;

Re: Resizing BitmapData without scaling

BTW Kim, "resizing" is actually the correct term for this. This code changes the number of BitmapData pixels on the x and y axes. Therefore, it is actually resizing. This code resizes the canvas, not the image. The reason that you get a black border is that you have resized a 400x400 canvas to a 600x600 canvas, but the image is still 400x400 - hence the black border.

This may seem stupid to you, but there are (rare) cases, where you are writing to a BitmapData object dynamically and you need to resize the canvas. The black border will go away as soon as you write new pixels to the enlarged canvas.

Before you try to troll on someone's blog, you may want to make sure you know what you're talking about.

Hey,
Thanks so much for this! It's exactly what I was looking for!

And for all the commenters who are complaining about how this doesn't scale the image... The post is titled "Resizing BitmapData WITHOUT SCALING." Duh!

Re: The Precocious QR Code

You'd think AS3 QR readers should work without any problems. Just look at the augmented reality libraries, their detection algorithms are similar (definitely more intensive) and they've been really finely tuned.

Re: The Precocious QR Code

Totally agree. While I'm sure there have been some really cool uses of QR codes, you never hear about them. It seems that the mass use of QR codes have been haphazard with little understanding of the tool on any level.

QR Codes are simply a tool to allow one person to get passed some set of data. When people think negatively about them it feels to me like someone complaining that drink glasses suck because they don't like orange juice.

Use of QR Codes for web sites in my mind is extremely short sighted and the cause for the distain and confusion. They've been abused as an advertising vehicle giving value only to marketing firms and taking advantage of users.

If I see a QR Code on a poster there are generally two options
1) I can scan it and get something *awesome*
2) I can scan it and get more advertising (movie trailer, bad web site, etc).

Guess what? It's almost always option #2 that comes to fruition because it's advertisers who made the poster.

I'm looking forward to people using QR Codes for all kinds of awesome things in the future. None of these awesome things include redirecting me to a mysterious web site and making me feel like I just wasted my time.

I entirely agree. I've really wanted to incorporate QR codes in my AIR applications, but I haven't had much luck with performance with the AS3 QR readers. that seems to be my only thing holding me back.
I'm curious how difficult a native extension of ZXing would be to create.

Re: Normalizing Angles

Kim Lindblom — Sat, 30 Apr 2011 07:50:02 -0000

Indeed it won't work if the angle value is too great, but it can be solved by substituting that if() statement for a while() so it keeps subtracting the value over and over until you have normalized the angle. Just place the return statement after the while loop.

Re: Resizing BitmapData without scaling

Kim Lindblom — Sat, 30 Apr 2011 07:39:43 -0000

You seem to have seriously misunderstood what's going on here. The image isn't actually made smaller in the sense that the motive on the bitmapdata is smaller on your screen. All you are doing is cutting away the edges around to make it fit into a smaller space, an action known as cropping, not resizing.

To demonstrate the flaw of your technique, try going from a 400px sized bitmapdata up to a 600px sized bitmapdata and see what happens. All you get is a black border around the image, because you are not actually resizing.

Your last statement is also a bit ironical. Because this is actually a very fast method, but it does not get the job done. I feel you should really have tested out your own code before you make a statement like that.
