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.

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 Repliesmy 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 1 RepliesOn my website, I display uploaded PDF files in a flash player for my users to read. I already use various tools to extract the text and produce a serious of high quality images from the file and the system works well. The last piece of the puzzle is to be able to highlight specific parts of the document to help users with accessibility issues.
However I cannot figure out how to calculate where the specific text is positioned on the page? Notes: The documents uploaded to the system are from 3rd parties, so fonts may be embedded. Meaning that I cannot be sure of the width of specific letters. The text to be highlighted may not be unique, the same text may be repeated How can I calculate the coordinates, height and width of a specific piece of text on a PDF, so that I can then draw a box around it?
If I had some numbers in an array, and wanted to calculate how many were below a certain value?

View 5 RepliesI'm looking for a jsfl function that can select all items on a frame and delete all strokes that match a specific color such as #0000ff
Basically I make a lot of notes with the pencil tool using red pencil strokes. But when Im done I just want to tell flash to delete all my red stokes from the screen and leave everything else intact. Any solutions to this?
I am coding a graphical interface using Flex, and I have a qestion related to masks in Flash.I want to create a kind of mask that defines which color and which alpha value a text will have according to its position on the screen. It is very easy to do that with the text being the mask of a bitmap, for instance.
However, I also want to take into account the color of the text itself.for instance, if I create a red text, in some zone it will be red with a modified alpha value, but on another zone, the text will be full white, as if there was a kind of mask which also applies its own color on top of it.
Is there a way to easily do this kind of thing? Of course, I can manually apply the format on the text according to where it is, but I wonder if there is an automatic processing like mask or blend mode using a DisplayObject as a processing pattern.
Since flex memory management is poor, objects once instantiated dont die very easily (even when they go out of scope), one would need to check on various properties of components. I am using one such thing to know if the screen (which is a display object) is in current view. For this I am turning on a boolean property (currently visible), and I am setting it true on show event of the display object.
What I need to know is, which event (something opposite of show, e.g left?) could be used when the screen is replaced by another display object?
Something like focusIn and focusOut from dotnet.
Or if there is some property which could directly tell me if the display object is currently in view (hasFocus doesnt seem to be giving me expected results).
I'm trying to create mono slide show, but I managed to be in some strange trouble. Namely mono slide show works nice, but something is wrong or missing in the code, because it puts the picture, that is pulled thru xml on top of everything. One solution is to do picture smaller, but i want to have buttons and info on the picture. It is not layer problem, because layer with picture container is on the last one. Heres the code:

I'm trying to prepend the byte array of a sound object to a captured microphone sound byte array.
It works, but the extracted sound object get pichted down and doubled in length. I guess this is because the byte array of the sound object is in stereo, while the mic byte array is in mono.
I have this:
sound.extract(myByteArray, extract);
myByteArray now contains the stereo data. How can I turn this to mono
UPDATE:
Here's a working solution:
existingByte.position = 0;
var mono : ByteArray = new ByteArray();
while(existingByte.bytesAvailable) {

Can I figure out somehow sound's frequency (primarily .mp3s) and if it is mono or stereo?

How can I turn every specific character in a word in a textbox to specific color? this works like highlighting. If I have the word Jeeves in TextField object, I would like each occurrence of Jeeves in this TextFIeld to become red or any other color. In AS2 I had to search the text for keywords and use the TextFormat class. and then handle keypresses for the textbox for highlighting as the user is typing. How can a highlight a text in dynamic text field?

What is the best way to hide specific (interpolated) color ranges? For example, I have a gradient that goes from blue > cyan > yellow > red. What I need is to hide blue > cyan, yellow > red but leave the cyan > yellow.
var rangeA:Object = {min:0x0000FF, max:0x00FFFF} //hide
var rangeB:Object = {min:0x00FFFF, max:0xFFFF00}; //show
var rangeC:Object = {min:0xFFFF00, max:0xFF0000}; //hide
It is ok to apply different filter for each range.
So, 8 weeks ago I started with my GameDevelopment branch of the MediaTechnology tree at my school, and I am currently in my 1st week of the 2d Semester (or Period, as we call it here), and AS3 is introduced this time (last Period were GameMaker and XNA).

I use this script currently to determine the difference between two dates:
[Code]...
The problem with this is I want to monitor the actual physical day change so if someone accessed the application at 11:59 PM and then came back 5 minutes later this would register as a 1 day difference (a new day), this current script requires atleast 12 hours to have passed between two dates for it to register as a new day.
I have thought about using the date number etc, but because months and years are so different it is quite a complex route, there must be something simpler.
I have this code :
var a:Apoint = new Apoint();
a.x =0; a.y=200;

b.x =275; b.y=100;

How to convert color image into single Color as3?
View 2 Repliesi 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?
View 2 RepliesI need to calculate the intersection between two shapes in flash / action script. The problem is I can't access the shape's nodes and segments, and their coordinates, so there's no way I can calculate this. Do you know a way?
edit: further explanation: I imported irregular polygons from an EPS file to a movieclip with shapes in it.The mathematical solution to the problem is trivial, but to do that, I need to access by AS code to the coordinates of the nodes that make up the polygons, which I tried with no success. That is what I'm trying to accomplish.
edit2: dismiss this question. It's not possible. The workaround I'm applying is to save the polygons in SVG and parse them to get a list of nodes. then will feed that list to flash to calculate the intersection and areas on runtime.
