I need a function that retrieves the average hexadecimal color values of a group of pixels in a square. Like a 4x4 area, and I want to be able to calculate what the average color is by retrieving the color of each pixel.
View 4 RepliesI'm currently making a color picker (pretty standard one, pretty much the same as photoshop with less options at the moment: still in early stage). Here's the picture of the actual thing : [URL] The problem is : to retrieve the color of the pixel that is under the color selector (the small one, the other is the mouse), I have this line that I thought would do it :
_currentColor = Convert.hsbToHex(new HSB(0,
((_colorSelector.x + _colorSelector.width/2)*100)/_largeur,
((_colorSelector.y + _colorSelector.height/2)*100)/_hauteur
));
Just to clarify the code, I simply use the coordinates of the selector in order to create a new HSB Color (saturation is represented on the X axis and brightness (value) on the Y axis of such a color picker). I then convert this HSB Color to Hexadecimal and assign it to a property. The hue is always set to 0 at the moment but this is irrelevant as I only work with pure red to test. It partially does what I wanted, but the returned color values are inversed for most of the corners:

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.
Is there a way of finding out the color of a graphic? For example if i have an array of rectangles, each with a different color set using graphics.beginFill(), can I then do something like:
color = rectangleArray[i].getColor();
i have a button, with instance name lightblue_color. I am assigning a color to its color field like this: lightblue_color.transform.colorTransform.color = 0x65ffff; then i am adding an eventlistener to the button like this: lightblue_color.addEventListener(MouseEvent.CLICK, ChangeColor); Then, in the function: public function ChangeColor(evnt:MouseEvent):void {trace(evnt.target.transform.colorTransform.color);} It prints 0. Why is that? Shouldn't it print 0x65ffff or do i need to do some type conversions?

I need a way to calculate lighter hex color(s) based on a provided one. I realize I could use a color transform, but I need the actual value in order to generate a gradient.

View 8 RepliesIs there a way to retrieve the color of a generic pixel on the screen using the mouse pointer inside the Stage of Flash Player? With the getPixel method of the BitmapData class you can get the color of a pixel only if the mouse is over a bitmap image, but what if I need the color a generic pixel on the screen?
View 4 RepliesSay I have drawn a triangle with[code]...
When the user clicks a point inside the triangle, we will get the x and y coordinates, do some calculation with those values and get some (lots) of pixel coordiantes accordingly (all of those calculated points will be within the triangle). And finally, change the color of those points (something different than triangleShape fill color).
my concept was I have webcam. My webcam is able to catch an image. Whereby, the flash will calculate the overall color of the jepg. And it will resize and place it to the nearest color of the main background color.

View 5 RepliesI have a spinning sphere, built using the away3D engine, it is wrapped in a bitmap. I need to be able to check the color value of the pixels in the sphere, however BitmapData only plots the 2D image, not the 3D sphere. So, the values become wrong. If I try to apply it to the sphere I get nasty errors. I have literally been stuck on this for days.

View 2 RepliesI'm having trouble with this code
var imageMap:ImageSnapshot= ImageSnapshot.captureImage(object);
var pixelValue:uint = imageMap.bitmapData.getPixel(x, y);
I have a bitmap with many colors on it. When the user clicks each color needs to trigger a different method. However, I have no idea how to check the color value of the selected bitmap. I can create a new sprite and check the value of that fine through bitmapdata.getpixel() but when I need to actually check the actual bitmap I cannot get it to work.

View 2 RepliesI 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.
I know this is possible to be done using javascript, and I presume I could get the values to flash calling js, but I'm looking for any AS3 library/code that does the same.

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.
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?

View 1 Repliesi'm doing a school project of mine and i am having trouble doing the changing color objects. here is an axample of the script that i;m using:
on (rollOver) {
var colorful = new Color("_root.shapes");
colorful.setRGB(0x003366);
}
For this script it does change color, but how do i make it to stay the same color that user selected after going to another scene?
