ActionScript 3.0 :: Extracting Certain Color From Bitmapdata?
May 25, 2011
basically my issue is that im trying to extract a certain color from my bitmap data, i have the bitmap data being created from an image the user specifies and i can/have drawn that onto the the stage, which works fine and dandy but what i need to do is extract a color from the image and present just that to the user but try as i might i cant get it to work

I'm trying to take a png and create two images, one that represents the color data and the other a grayscale version of the alpha channel.
Extracting the correct data was no problem, i'm just embedding the png, creating a new instance (as a Bitmap) and then extracting the relevent channels of it's bitmapData to two new bitmapData instances.
ActionScript Code:
[Embed(source='/../deploy/images/alpha_test.png')]
public var image : Class;
[code]....
The problem that i'm having, is that when i assign the colors bitmapData to a bitmap instance to display it, the background color is showing as black, even though the default fillColor of a bitmapData instance is white. how i can use the alpha channel data to create an 8 bit, grayscale image, that's the reverse of the channel?

I'm trying to replace a range of colours programmatically - I have sprites for a game that have parts of them in shades of magenta specifically so they can be recoloured to show their team colour (blue,red,etc).I've been able to use BitmapData.threshold() to replace a single specific colour with another. What I need to be able to do though is set some sort of range of colours and appropriately shade them blue/green/red while keeping their relative light/dark shades.Here's what I've used to do a single colour:
Code:
var thisBitmap:Bitmap = MySpriteBitmap; //source bitmap
var colouredBitmapData:BitmapData = new BitmapData(thisBitmap.bitmapData.width,

I need to create, from a given Bitmap/BitmapData of a PNG file which has transparent and semitransparent pixels, another BitmapData which is a copy of it, but all the pixels (well, the pixels that are not alpha 0% actually) must have a specified grey color value (0xdddddd).

Let's say you have an image of a cartoon human that is wearing a blue jacket with white sleeves, blue shoes, and grey pants. Brown hair and biege skin tone.(My project actually has 1300 of these images - 325 are blue cloths, 325 are red cloths, 325 are green cloths, and 325 are purple cloths)I am having a major problem with file size and memory usage due to all the images, so I have been asked to see if there was a way I could programmatically change the clothing color... this way we can use any color we want, and only have 325 base images.I have been trying to play with color matrix filter and color transform, but I can't seem to get the hang of itIs there a way I can extract only the "blue" colors from the image and do a hue shift on it to the color that I want it to be without effecting the non-blue colors

I have a map (map of a mall, top view) with some colors. I´m removing the part for walking of the map, which has a type of color (say 0xcccccc).
I got all the 0xcccccc color pixels removed (setted to another color), but it seems to remain a bit of gray at the walking part.
The color of that bit it´s close to 0xcccccc. It looks like flash not succeeded while removing the walking part. But instead, leaved some parts (like borders or something) on the bitmapdata.
I´ve tried to remove by script, by picking the colors remained on the bitmap, but the loop doesn´t find these colors.

I'm looking for an efficient way to filter a specific color from a bitmapData object in ActionScript 3. Currently I use a loop with readByte32(). This takes about a second to process which is unacceptable. I have been trying to get paletteMap() to work but so far haven't been able to grasp its API (any truly useful links? Google has failed me...). Here's my current logic, which I want to improve:

I am trying to use the reflect class from "http://pixelfumes.blogspot.com/2007/03/reflection-class-v3-with-source .html" but I keep getting this error:
ArgumentError: Error #2015: Invalid BitmapData.
at flash.display::BitmapData()
at Reflect()
at Site_fla::GalleryPage_29/loadThumbs()
at Site_fla::GalleryPage_29/sortXML()

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.

I've made a mobile version of my software, with low-res images and such, and I can now fully buffer all my content (including a 360 frame animation which is buffered to memory). Problem is, that everytime I update the view, more memory is used.When I write image = new BitmapData();, does it store the previously created BitmapData's in memory? Do I have to flush the memory somehow before I draw my second picture in BitmapData?Example:

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 am having an issue with using BitmapData.draw(stage). I am getting the following error:
SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: file:///C|/Documents%20and%20Settings/bla...bla...bla.swf cannot access null. No policy files granted access. Here is a portion of my code:
var bd:BitmapData = new BitmapData(2800, 2100); bd.draw(stage);//this is where the error happens All of the files referenced (.xml/.jpg/.swf) are located in the same local folder as the main .swf. How do I get around this error? The main objective is to print the stage using PrintJob(). I am using Flash Professional CS5.5 and publishing to Flash 10.0/10.1. Let me know if I need to supply any more info.

The XML file format is:
<xml>
<condesa>
<lote>
<loteid>H50601</loteid>[code]....
I have an xml file that I am reading from. I am them taking the data and putting it into an XML object named condechiXML.
var condechiXML:XML = new XML();
var XML_URL:String = "condechi.xml";
var condechiXMLURL:URLRequest = new URLRequest(XML_URL);[code]...
What I want to do is run a for loop for every branch in my xml tree where I access a property in each branch. I have the for loop working using the length attribute for xml but when i want to use:
for (var i:uint=1; i<=condechiTotal; i++) {
trace(condechiXML.condesa["lote["+i+"]"].loteid);
}
my trace returns blank lines.

i was wondering, how can i extract thumbnail from a flash-video file, then display it in a listbox.the listbox is suppose to have many videos which i need to extract thumbnails from programatically with actionscript.the flash-player is going to be on the web, and the extraction must happen when the swf file is loading, therefore, the method must not be too time-taking.

have a SWF that I want to extract VideoFrames from.They appear under this name when the SWF is opened with 7-Zip (VideoFrame).Obviously, extracting them in that manner accomplishes nothing, as they are not in any recognizable image format.I have loaded the SWF into Flash Professional CS5, and am able to view all the Bitmap objects (assembled in a "UI", overlaying the video animation at one corner) in the Library, but I cannot find an enumeration of the video frames anywhere, or even find the object displaying them.
EDIT: I do NOT want to simply export the entire frames of the SWF, as there are several UI elements overlaying the video. I know for a fact that the entire video frames are present (just partly covered up). I want to extract the frames of the embedded video, not the SWF frames.

I am currently working on a project which relies on variables and constants defined in an external .swf-File. As I don't have the sourcecode to the .swf file I need to extract the content of these variables by decompiling and copy&pasting the variables by hand. I was wondering if there is a way to extract these variables by analysing the bytecode using c++ for instance.

I am using the loadVars class (Flash 8) to load key/value pairs from a mySQL database through php (example &pic1=pic1.jpg&pic2=pic2.jpg&...).
The ultimate goal is to create a dynamic slideshow with a variable length, depending on how many pics were submitted by the user. Since the associative array object returned by loadVars does not share the "length" property of indexed arrays, my guess is that the values need to be converted into a new indexed array before being able to use them in the slideshow.

I'm having trouble extracting the data from an XML file that I've loaded into arrays in flash.
Ultimately the XML file will sit on a server and will be updated separately from the flash file.
What I am trying to do is get text boxes to pull in the data from an array when a button is rolled over.

string = justsomerandomstuff.Count:12562morerandomstuffI need to extract the "12562"I never know how far in the string this number will be, but I do know it's 1 character away from the word "Count". Somehow I would need to find the position of the string "Count within the variable, add 1 and extract the numbers. Also the the number is not always the same lenghth, so it would also have to work with this:string = justsomerandomstuff.Count:14238960morerandomstuff.

This has got to be easy, just escaping me, and sick of searching for "almost" the right answer. I'm trying to get at the actual data enclosed within a CDATA tag in an XML file.
Here's a sample of the XML file :
Code:
<?xml version="1.0" encoding="ISO-8859-1"?>
<webdata>
<page id = "Page1">
[Code].....
What do I need to change so I just extract the data within the CDATA tag?
I want to get at just this :
Code:
