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 have a bounded object, created using primitives lines in Action Script- either an oval or a triangle. Is there any way I can fill the contents in a specific color
Just to clarify on this- the shape could be in two ways
a) drawing a isoceles triangle based on a variable apex angle
b) two curved lines to form a "lens"
I am not sure if I can use the fill function, as I am not drawing a inherently bounded shape- the closed nature is based on my calculations

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:

I have a sprite which is 125px by 125px. A circle is drawn using the graphics object of this sprite. The circles midpoint is 0,0 of the sprite. When the user clicks the sprite an event is fired. How do I retrieve the colour of the pixel that the user clicked on the sprite?

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?

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).

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.

i have found a beautiful water effect made in as3. The effect is available to download on the website below.I am trying to change the fill of the water (that is blue or any color that you pick).The original code fills the water like this:
Code:

shape.grapics.clear();
shape.graphics.beginFill(0x006699);
shape.graphics.lineStyle(0, 0x000000, 0);

I tried to follow the instructions on the beginBitmapFill help, but i am receiving the water with no fill.

View 3 RepliesI am looking for a fairly simple image comparison method in AS3. I have taken an image from a web cam (with no subject) passed it in to bitmap data, then a second image is taken (this time with a subject) to compare this data, from these two images I would like to create a mask from the pixels that match on both bitmaps. I have been scratching my head for a while, and I am not really making any progress. Could any one point me in the right direction for pixel comparison method, something like getPixel32()
View 2 RepliesUsing Actionscript 3 is there a way to search one bitmap for the coordinates matching pixels of another bitmap?

Somehow you would have to loop through the bigger bitmap to find and the the pixel range that matches and return those coordinates. For example the Bitmap with the "E" is 250 pixels over and 14 pixels down in the bigger bitmap.
Is there anyway I can effectively call the equiv. of setText on a Flex Graphics object ?Specifically I'm using a custom cell renderer to display data in a datagrid. The renderer uses the Graphics object to set the background colour of only a portion of the cell (say the left half) based upon the underlying data. I would like to be able to have text over only that portion of the cell which has the background colour (eg centred within the left half). I know all the widths (of both the cell itself and the graphics object) but I don't know how I can set text (centred) over the graphics object.

Lets say I have a customMovieClip. I sometimes draw an ellipse with customMovieClip.graphics and sometimes a rectangle. Now I want to know what was the shape ( ellipse/rect) that was created using a particular graphics object. Doing this would enable me to pinpoint what exactly to do with that customMovieClip() instance.
