Actionscript 3 :: BitmapData Built-in To Bitmaps?
May 25, 2010
i've used a Loader and URLRequest to download a .png from the internet and add it to my display list. since it's already a bitmap, does it have built in bitmap data already? or do i have to create the bitmap data myself?also, why does the same trace statement return false in the mouseMoveHandler when it outputs true in the displayImage function?
var imageLoader:Loader = new Loader();
imageLoader.load(new URLRequest("http://somewebsite.com/image.png"));
imageLoader.contentLoaderInfo.addEventListener
[code].....

I has a series of bitmaps which have been broken apart in flash, I want to know if it is possible to go into these bitmaps using their bitmapdata and edit them based on information on the arrays that I get. I.E. I want to delete the transparent pixels each one has.
Obviously I can do this by hand in photoshop or just using the lasso tool, but I have several thousand bitmaps that I have to edit, so I'm hoping theres a way to do this through code.

I want to load .jpg images into flash and store them as BitmapData objects. I've coded the loading of images many many times but I've never tried to store them as BitmapData, I just usually add the Loader to the display list and manipulate the image through its loader.
I feel like this is a very poor approach and so I want to try just saving BitmapData, because on the Model side of things thats really all I need.
Now the only way I have found to extract BitmapData from a loaded JPEG is to load the JPEG and upon completion write:
myBitmapData = Bitmap(loader.content).bitmapData;
First, is there a way to extract the BitmapData without encumbering the code with the Bitmap class? In other words, is there a way to extract that information without involving the Bitmap class - BitmapData while useful for a Bitmap is not dependent on Bitmap so ideally I would never involve Bitmap here.
Also, why is this Bitmap type-casting so widely accepted? loader.content is a DisplayObject and therefore is not necessarily compatible with Bitmap. Further, for all Flash knows we just loaded an SWF and as far as I know you can't typecast that to a Bitmap.

I am trying to copy multiple movieclips to one movieclip using BitmapData.
I am trying to clear out the old bitmapdata from the movieclip that I am adding my bitmapdata to. The two movieclips I am copying are different sizes and shapes so I can't just overlap them.

I've been working on a simple mosaic generator for a project and have been crashing Flash consistently by trying to add too many bitmaps to a Sprite. I can crash Flash every time with the following:
for(var i:int = 0; i < 10000; i++){
var d:BitmapData = new BitmapData(20,20);
addChild(new Bitmap(d));
}
I get a 2015 error - invalid BitmapData.9000 works without issue... 10000 crashes. Problem is I need 10000.Is this a known limitation? I could try using multiple sprites and adding say 5000 to each, but that wouldn't be easy with this project. But if I have to I have to...

I'm trying to figure out the best way to compare a single bitmap against perhaps an array of saved bitmaps to see how close of a match it may be to any one of the bitmaps stored in the array. Right now I'm running a for loop that uses the bitmapData.compare() method to try to compare to see how much of a variance there is but... to be honest I'm at a loss as to how to use the resulting data to do so. Does anyone know of any good method to accomplish what I am trying to do? Forget looking at my code it's a waste of time because simply, it's not working.

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()
[Code]...
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 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 title might be a little misleading. Look at my code and I will explain
public static function loadTile(tileDir:String = "empty"):void
{
if(tileDir != "empty")
{
tPoint = new Point(0,0);
tRect = new Rectangle(0,0,30,30);
[Code]...
I am trying to do tiling with sprites. I want my tiles to be interactive, so that is why I am using the sprite object instead of using regular bitMaps to represent my tiles. You might be wondering why I wouldnt just use graphics.beginBitmapFill(tImage); and graphics.drawRect(0, 0,tWidth ,tHeight ); to pick out the tiles I want to use. Well reason being is because it turns out that drawRect() first and second parameters actually alter the location of where the actual sprite sits at.
So if I set the x and y properties of the sprite to x = 20, and y = 20. then I set my drawRect(20,20). it actually adds an extra 20 pixels to my x and y coords of my sprite. And I know the reason why, I just need to know a better way.

I did a xml image gallery, with buttons for each image (using the duplicateMovieClip function + a for loop).Now i went to next step, I need to make a scroll for the menu, BUT, i don't have any idea how to set something to happen after the for loop is done.
My code so far:
Code:
stop();
var yPos = -10;
var depthCount = 1;
[code]....
Just for a simple test (since i noticed what i tried wasn't working well), I added a test movie clip and added a _visibile = false to be executed, i added it right after the closing of the for loop. I didn't had sucess thou, it happened before the loop .

i've come to realize there's no "wiggle" class built into as3. i mean an affect similar to the wiggle command in AE. so i've been making my own and been banging my head on stuff the past few days cuz of this.i've got something!...but i can get the code to work ONLY if i make the constructor a method instead. but when i do that all the movieclips the method in the fla is applied to wiggles around the same place. see:URL...so i figured the way around this was to make the method a constructor of an object. then in the lfa instance a wiggle object to wiggle movieclips. but now im getting a ArgumentError: Error #1063: Argument count mismatch on wiggle().

I'm currently working on converting an Android app I built natively as an iPhone app. I'm recreating it in Flash as I know AS3 but not Objective C. My original Android app is localized for 4 different languages (it's so easy to do with Android!) - and my question is - how would I do this for the iOS version from Flash? Would I be able to use separate XML files with all the strings in each language and load them in after somehow detecting which language the user's device is set to?I ended up using the following code:
var languageSettings:Array = Capabilities.languages;
var locale:String = languageSettings[0].toString().toLowerCase();
This gave me a 2-letter language code: 'en' for English, 'de' for German, etc. which I was able to use to load the correct xml file for each language.

I have been fighting with this for nearly a month, (My wife is tired of hearing about it) and have been avoiding putting the question onto this forum because it feels like it's just within my reach. But obviously it isn't.
I have the code set up to dynamically build this calendar. It works for the month we're in but attempting to go to the previous or next month does not work. Sometimes next month works actually.
Ok I just checked it and it really only worked for October and now it is incorrect for November. The problem is determining the first and last days (i.e. Sunday, Monday, etc...) of the month.[code]...

On this website [URL] you will find a big flash applet at the top of the page. It has a sharedobject built in. Every time the applet goes to a new slide/scene (which it automatically does after x seconds), it updates the SharedObject so that once you refresh the page you end up at the same slide/scene again. Now the thing is that it does this only correctly in Internet Explorer.
Code:
var so=SharedObject.getLocal("pagehit");
if(so.data.pagehit != undefined){
/* Er bestaat al een cookie */
if(so.data.pagehit == "Scene 1"){
gotoAndPlay("Scene 1", 1);
};
[Code] .....
This is the code of Scene 1. Where you get forwarded to another scene if the cookie exist.
Code:
so.clear();
var so=SharedObject.getLocal("pagehit");
so.data.pagehit="Scene 2";
so.flush();
This is the code of the other scenes, ofcourse with a different scene number for each. It doesn't depend on the browser but on flash alone.

I've spend the last 6 months developping a Flash (CS4 / Flash v10) game. As I'm now ready to publish it online, I would like to ensure that my actionscript code is safe. Hence my questions are: - Is the CS4 built-in password protection safe? (I guess not given that my actionscript still needs to be executed hence has to be readable for the client)
- What are the best options to further protect my code? (I guess obfuscation is the most common approach: which obfuscators are good?)

I am have about 80% of a my website built and buttons all mapping where they should go, along with a number of XML driven BANNER ROTATORS/ACCORDIAN MENUS...ect
This site requires users to be signed in, which is done through a site previous to mine. Once they log in, they can click a button which then allows them access to my site.
My site has three "user levels" or "autentication levels" as we have "Managers", "Supervisors" and "Staff" levels.
For testing purposes, we have placed the below actionscript in the first frame of my project. The purpose of this actionscipt is to reference the "authentication level" that the user is using (as they will have already signed in so we are simply looking to obtain their "auth level").

how to go about getting the Flash Player(s) that's built into the CS5 IDE updated? According to System.capabilities.version, it's running v10.1.52.14 which, according to this page on the Adobe site, says was a pre-release version of Flash Player and should not be used! It also seems to have an annoying bug where HTML tags are frequently shown as raw HTML, rather than being rendered, which makes testing stuff in the IDE a real pain.

A few days ago I decided I wanted to make my own drag&drop flash components, with inspectable properties. Since the documentation for flash components is so limited, I followed the workflow of some blogs I found around the web (mostly about CS3 components). In the end I managed to create a component that has a Live View, that gets a visual update whenever you change the properties (width, height, color..) ....in CS4 !
The problem in CS5 is that when I drag my component on the stage, the timeline of this movieclip starts playing in a loop. As you may or may not know, Components have 1 "Avatar" frame, and 1 "Assets" frame. So this looks kinda weird when that timeline plays.
There is always the possibility that I made a mistake, but when I download the source files from the blog post on the page http://active.tutsplus.com/tutorials/actionscript/creating-flash-compo nents-for-distribution/comment-page-1/#comment-33865
the same thing happens.
When I then save my CS5 FLA as a CS4 FLA and try to use the downloaded component and my own, both of them work fine in CS4. So I think this might be a bug in CS5.? Which is pretty bad because I wanted to use these components in iphone development using the CS5 packager...I read somewhere that we actually use the UIComponent because it has no timeline, so I don't see how it's possible that it plays.
I uploaded my source files to [URL]

Lets make it simple. Lets say I have the stage with a combo box. I will have 100 frames with the combo box tweening from position to another. I easily can do it and see the animation of the combobox over the timeline. But when I create the swf file, the animation doesn't work. This also happens to all the other components. They don't accept any type of animation except if they are embeded in another movie clip.
