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.
View 3 RepliesI want to create a flash document that allows me to change the colous of an image using a colour palette of my own. I am a complete beginner and have no idea where to start this, hence i would need to know what to do and how to do it. I basically want the image to be a simple 2d image that i will create using different layers in photoshop and import them into flash, the layer images will all be one colour so the colour of the whole layer changes. so the colour palette will be on the side of this and when i click on an image and then a colour the image changes to the colour i clicked.
View 3 RepliesI am parsing colour codes that I get from a Flex(Flash ActionScript) application, then creating HTML div elements with that same colour. My Problem: The colours are all only 8 digits long. So they cant be RGB colour values can they? What color value format are they in? If I can figure the format they are in I can convert them to RGB. Maybe the last/first digit signifies its 0. alpha value?
PS: Should I convert the colours to RGB or something else?
This is an example of the colour code values I getting from the flash application:

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.
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.
View 1 RepliesSo, 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'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.
So I've got an input box on the UI, where integers are entered and stored in an array. I want to find out the average of the integers, but how would I calculate the sum?

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.

btw, first I used assigned thumbContainer as the mc argument (outside the loadThumbs() function) and it worked but not exactly what I wanted... because I thought it is supposed to update when the movieclip is animated but it actually didn't... when I use a scroller, only the thumbs that are first loaded to the stage get the reflection..
I've been using BitmapData.copyPixels() to draw graphics onto a canvas (Bitmap).I need to rotate the resulting graphics without the use of draw() because it's vastly slower.How can I rotate the target graphic? I'm assuming that there might be a formula or library that I can use which will first reorganize the pixels that make up a graphic based on an origin (point) and radians.I'm pretty certain that I'm not capable of creating such logic, so if there are any known libraries that do this, that would be awesome.I'd like to achieve something similar to XNA's SpriteBatch.Draw() method, which accepts rotation as its 5th argument.

public static function loadTile(tileDir:String = "empty"):void

I am trying to do tiling with sprites. I want my tiles to be interactive, so that is why I am using the sprite object instead of using regular bitMaps to represent my tiles. You might be wondering why I wouldnt just use graphics.beginBitmapFill(tImage); and graphics.drawRect(0, 0,tWidth ,tHeight ); to pick out the tiles I want to use. Well reason being is because it turns out that drawRect() first and second parameters actually alter the location of where the actual sprite sits at.
So if I set the x and y properties of the sprite to x = 20, and y = 20. then I set my drawRect(20,20). it actually adds an extra 20 pixels to my x and y coords of my sprite. And I know the reason why, I just need to know a better way.
