Oct 6, 2011I 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.

Jul 28, 2011I have camera input app in flash (AS3) and I draw some graphics over it. I want to take the image snapshot of the stage visible area but only the video an graphics I draw over video. I want to exclude controls from the image snapshot. My display object layout is in following relation:
-stage
--canvas (Sprite)
---video (Video)[code]..........
Stage size is fixed and I want to take a image snapshot of everything that is child of my canvas element (camera input video and overlayed graphics, but excluding controls). I am able to make this image snapshot when overlayed graphics are inside the bounds of stage size. I do it like this:
var bmpd:BitmapData = new BitmapData(canvas.width, canvas.height);
bmpd.draw(canvas, new Matrix(1, 0, 0, 1, canvas.x, canvas.y));
But this gives me unwanted result when graphics which I draw on top of video on canvas exceed the bounds of stage display area. How do I limit the image snapshot only in the bounds of visible area inside stage?

Sep 28, 2010I'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:

ActionScript 3.0 :: Getting The Average Pixel Value Of The Rectangular Area Behind A Mc?
Nov 28, 2009I 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.

The 2nd is a series of button logo PNG's for an additional visual button state change.I add the logo MC with addChild to the button body. Then I add the button body to display/stage container. ll is layered correctly.If I add alpha or transform the color to the button body, it goes to the top - covering the button logo.Not applying the color or alpha to the button body and applying a color or alpha to the button logo has not effect (displays correctly).

Flash :: Display Objects Which Are Outside The Display Area When Is Embeded In HTML?
Nov 22, 2010Is there any way to display flash objects which are outside the display area when flash is embeded in HTML
The reason i ask is my current project has a rotating + enlarging effect which is largely dynamic so sometimes an object may clip the edge of the stage areathis looks messy but i dont want to increase the stage area to cover the largest possible area any object could enter because most of the time the objects are at the center and small so i would end up with a lot of white space

Oct 21, 2009I have written a class that masks a given area. What that mask does is this.It creates a given number of circles, puts them in random positions on the stage and then expands them.the problem is that once the masked area is full I need to remove the on enter frame listener, otherwise it keeps expanding the circles. thus hammering the processor.Is there any way to detect if the given area is full?

ActionScript 3.0 :: Changing Color Of Area With ComboBox?
Sep 2, 2008I want to change the colors in the geographic areas in a map based on which selection was chosen from a comboBox where the hex color codes to be used are stored someplace (xml file?). For example, if user chooses "1980" in the combo box, Minnesota will be blue, but if user chooses "2004", Minnesota will be red. an example of or tutorial on how to do this? At this point, I don't care if it's with AS2 or AS3. I assume each geographic area would be an object whose color is set after each selection. But rather than start from scratch, I'd love to see an example that's close to what I want.
