ActionScript 3.0 :: Get Average Brightness Of A JPG Movieclip?
Feb 22, 2011
I was working on a project a few months ago, which I had to put on hold but am finally getting back to. One major feature I need that I wasn't able to figure out before was how to measure the average brightness of an image file loaded as a movieclip. I remember spending hours going through tutorials but I wasn't able to get it working. Now I don't even remember what or where I read before and I'm not keen on rereading all of it and still not knowing what to do.
I just want the simplest possible way to get an average brightness level of an image, I don't care which way the brightness is measured as it is only important relative to other images which will be measured the same way.

Does anyone know how to control the brightness of a movieclip through action script. I can't seem to find the syntax for that property (if there is such a thing).

I have Flash 8 set to Actionscript 1.0.
On the main timeline I have a graphic of a hill and tree that darkens when clicking a button. I also have a movieclip called "creature" that has a little creature walking from one end of the stage across to the other. I need a script that will control the brightness of the "creature" movieclip at the point where the main timeline animation goes dark because the "creature" movieclip sticks out like a sore thumb at that point and needs to be darkened.

I made involving the user inputting 4 different numbers into seperate InputText component boxes. I have an output showing "Your Average Is _____ " but i keep running into a problem saying "Your average is NaN". Here's my code, tell me what is wrong with it.also, Flash shows no errors in my code. It's just shows NaN.
Code:
var average:Number;
grade1.restrict = "0-9";
grade2.restrict = "0-9";[code].....

Is there a way to loop through all the pixels of a bitmapData object to find the "average" colour or light level? I basically want to make a light level detector using the webcam. Does anybody havehow I could accomplish this? All searches I have tried return tutorials on motion tracking.

I am wanting to take the average x co-ordinate of several movieclips, mc_01, mc_02, etc. using arrays. That is, I would like to sum all the x co-ordinates and then divide by the number of movieclips.

So, I've got this [code]...
Is there a way to get, efficiently and quickly, the dominant color and/or the average color in pixels ByteArray.
noise is used for the example here. I'll be having something else drawn on that BitmapData instead.
I found some ways to extract the average color palate from a BitmapData, but this isn't enough for me since I want the average from a rect over that image.

I have a vector movie-clip of a cat. Behind it, there is a picture of a park. The picture of the park takes up the entire stage, but the cat is only 32x16. How could I use BitmapData to sample all pixels (of everything, not just the park) within the cat's bounding box (but not including the cat itself in the samples (so like the cat is invisible); also 4 pixels wider in each direction, so it would effectively be 40x24) and then return the RGB average (in hexidecimal) so that I can set a masked transparent mc in front of the cat to that value?
Basically, so it looks like the color of the cat's surroundings affect its tint, to crudely simulate global illumination in 2d.

This can't be too difficult but its killing me. I want my user to be able to type 3 numbers into 3 different input boxes, capture those numbers, calculate and display their average in a fourth text box.
I am not sure how to capture input from a textbox in AS3 in order to do these calculoatilo.

I'm trying to create a balance beam for an education video game and am having trouble making the balance look just right.When the student slides the weight on a triple beam balance, the beam rotates from its pivot to show how far off the weight is. The student then continues adjusting it until the weight matches. My problem occurs because the length of the weight arm means the rotation values are very small, range -4 to 4 degrees, and when the student gets within a few grams it appears level.
My question is how to create a mathematical curve. Like 100 = 20, 50 = 15, 20 = 10, 1 = 4, .2 = 2, etc, so that I can have large movements towards the more accurate side and less when the weight is far off.

I'm having AS3 create 12 random var (play1, play2, etc) and then I ask it to average the 12 vars (numbers) until I get a specific average number. When I run this in AS2 I get the "script time error, keep running?" question. I tell it to keep running and eventually AS2 finds the right set of 12 numbers to equal a specific average number. In AS3 I get a "stack over flow error". I know that all my AS3 swf needs is just more time to find it.

But I also want to scale the brightness of it. Is it even possible?

I have a brightness file with 'actions' running error free....... But my final result won't do anything....
The file executes and the slider works but the picture doesn't get brighter or darker at all..
ActionScript Code:
import flash.display.Sprite;
import fl.events.SliderEvent;
import flash.geom.ColorTransform;
[Code].....
I have imported all SliderEvents , ColorTransform, and Sprite events.. I defined each variable and gave both my 'image' and 'panel' their instance names.
My 'bValue' textfield has been given the instance name of 'bValue' .... here's the file to show you all what I mean.
What else do I need to do for this to actually do something??? I studied a little as3 in the past and learnt how to make mc's and that's about it...

This is my fully working brightness slider.
ActionScript Code:
var colorTransform:ColorTransform = new ColorTransform();
function Main():void
{
[Code]....
today I'm attempting to store the current value in my slider so I can trace the value...
How should I store the brightness value?? should I create a new variable such as
ActionScript Code:
Var:currentValue:colorTransform
I tried to do that and it just gave me 'null' when I traced it. I used trace(currentValue). and it gives me '0'. even when I go brighter!

What I'm trying to achieve is have my images "flash/shine" when the cursor passes over the image, however; I want it to adjust to say +100, then back down to 0 immediately, not on roll out. The code I have thus far works perfectly fine for over and out.
Code:
sBright = 0;
eBright = 100;
stepValue = 25;
