ActionScript 3.0 :: BitmapData = New BitmapData(); Eating Up Memory?
Dec 22, 2011
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:
ActionScript Code:
// In this example I draw using the same bitmapData several times, also
//overwriting the first image. Do I have to somehow delete the data first, to
I have an application which manipulates high resolution images (something around 100+ megapixels), and I'm having some memory issues. When the BitmapData object is created, it allocates memory to store this image. The problem, is that I already have a ByteArray with this image's pixels (which have something around 400+ MB), so when the BitmapData is created, it allocates memory to store the same data that I have on the ByteArray. After its creation, I can set the pixels from the ByteArray to the BitmapData and free the ByteArray. But this memory peak is, sometimes, causing the runtime to raise an exception, telling that the system is out of memory. Is there any way to tell the BitmapData to use my own ByteArray? Or any other solution that I don't have to use double the memory that I need?
When I publish the file, I'm getting the following error message in the Output panel:
**Error** Scene=Scene 1, layer=Layer 2, frame=1:Line 7: The class or interface 'BitmapData.loadBitmap' could not be loaded. var plaid:BitmapData.loadBitmap("plaid");
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.
how to use the bitmapData collision method. Now I'm trying to figure out if there is a way to see at what angle or coordinate of the bitmapData the collision happens? I need it in order to figure the accurate bounce angle after the collision occurs.
I have a large sprite...and I'm splitting it into several smaller ones with function bellow. The function works great but the memory usage of my .swf grows dramatically.
private function split_sprite(sp:Sprite,the_parrent:Sprite) { var region:Rectangle = new Rectangle(); region = sp.getBounds(the_parrent);
I'm currently working on a flash game and I need to know how to addChild a BitmapData or draw a BitmapData to screen. If I can't than how can I give a DisplayObject my BitmapData?
2: Without altering it,I make a copy of it and use it display to users in resized format
note: I won't display the original image.
3:Now when user deletes the resized image,i need to delete the image loaded as bitmap i.e. the original image which i won't be displaying
For that I used bitmap.bitmapData.dispose() method.But,it doesn't free up the memory taken by the bitmap.For instance at initial state the memory usage is 58 Mb and upon loading 3 images the size increases to 87 Mb.And when I delete all the images the size decreases to 81 MB only.
I've got a flex component which works pretty well but unfortunately turns into a disaster once used in a datagroup item renderer of about 40-50 items. Essentially it uses bitmapdata to take screenshot of a fully-rendered webpage in mx:HTML (this version of webkit rocks btw, miles better than flex 3). The code is pretty self-explanatory I think. [URL]. I've optimized it all I could, browsed, search for answers and already trimmed it down a lot, I'm desparate to reduce the memory usage (about 600mb after 100 draw). The Garbage collector has little effect.

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.
I have created a swf interactive content, but I notice that the more I click on the buttons, the more memory it consumes, how can I prevent flash consuming my memory instead of closing the entire flash and reload it again?
I have developed an online chat application based in AS3. Users report the chat gets really sluggish after sometime. Days of debug point to the flash movie growing in memory! The only thing I can think of is the dynamic text field i have in there where chat is displayed. Is there any way to "purge" some old text? To add text to the dynamic text field i use:
I have been working on a flash game where I add sub-animations to a movieclip by attaching child movieclips. This creates a hierarchy of movie clips with different animations, but the result of that was that the parent movieclip ended up growing indefinitely and eating lots of memory. Is there a way I can optimize such animation? If bitmap caching works, would I be able to cache all the children which were added before runtime (e.g children movieclips which were added during design and before publishing the SWF).
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.
So due to my lack of time to research this and my strong curiosity for the matter:Does anyone know of any publicly available classes or ways to convert an array of BitmapData to a video format ByteArray (going to save it since I'm using it in an AIR project)?
I was considering writing my own class for it but started in the research and decided it's a very highly developed field and is hard to quickly find the basics of how to handle it. Thus it's usefulness outweighed it's opportunity cost for the time I have unless there is an already made class for handling this.
Mainly was considering this for short clips that one would create for logos etc so that one can display the logo in other environments with ease.
I have a bitmap with a different bitmapData on it (done through copyPixel) and I was wondering whether there is built in function that can determine what BitmapData the user is clicking on? how to best figure out which BitmapData is clicked, or do I have to do x,y pos comparisons manually?
Are BitmapData objects automatically GPU accelerated for rendering, rotating, and scaling,or does the bitmap they connect to need to have cacheAsBitmap set to true?
I'm trying to load several jpeg images dynamically XML into bitmapdata object in fla. I can see them on the stage of this .swf file.However, I load it into another .swf which is my main to call while clicking on one of menu option.I got this error:Error #1034: Type Coercion failed: cannot convert com::Fashion@1daf4ca1 to flash.display.MovieClip.Does anyone know how to convert that??
private function initBitmapFile(file:String):void { loadBMP = new Loader();
I'm trying to replicate this function from the Allegro graphics library:
void stretch_blit(BITMAP *source, BITMAP *dest, int source_x, int source_y, int source_width, int source_height, int dest_x, dest_y, dest_width, dest_height);

This is somewhat difficult in Flash, because of the overlapping functionality between the Rectangle and Matrix arguments of AS3's BitmapData.draw() method. This is what I have so far. It only works most of the time, and is incredibly inefficient (due to having to sample pixels twice).
I am trying to serialize a Bitmap to store in an XML file. My plan is to turn the BitmapData into a byteArray, but I haven't been able to fine an example of this.
I need to load a very big image on AS3 (currently sized at 8192x8192). I am aware that it does not fit any of the limits imposed by Flash regarding drawing to screen or creating a BitmapData of that size. I just want to load the image so I can copyPixels() some parts of it here and there.The thing is, I'm loading the .jpg file of that size with no problems. The size is recognized correctly from my Loader object. I load it like this:[code]But I am greeted with the #2015 "Invalid BitmapData" error usually reserved for BitmapDatas that are too big. The error also happens if I try to do a copyPixels(), which is what I need to do.Is there any workaround I can use so I can get data from an image this big on AS3?
I have a BitmapData object created dynamically that contains user-drawn shapes. I then attach that BitmapData object to a MovieClip via a Bitmap object and set that MovieClip as a mask to another MovieClip. The mask works but the whole bounding rectangle of the BitmapData is acting as the mask. But I want to exclude the transparent portion from the mask so only user-drawn shape can be set as mask. Can anyone tell how to achieve that?
I'm trying to convert all letters in a textfield to bitmap data. I then want to animate each of them. I'm able to return an array of rectangles using getCharBoundaries. But then how do I convert each letter to BitMapData?
I have a filled Shape, and a BitmapData that is the same width and height as the Shape's bounding box. I need to cut the Shape from the BitmapData (basically draw the BitmapData onto the shape...) [URL]I use the rather hackish method of:
public static function cutPoly(img:BitmapData, s:Shape, bounds:Bounds):BitmapData { var temp:BitmapData = new BitmapData(bounds.width, bounds.height, true); Main.inst.stageQuality("low"); //hack to kill anti-aliasing
Im making a simple game with destructable terrain. Therefore i use a bitmap for the ground and a movieClip for the player. When the ground is a bitmap i cant use regular hitTestPoint because of the bitmaps transparent pixels. So i looking i the livedocs for the bitmapData.hitTest but i rly dont understand all the parameters.So my question is. How can i reproduce this with bitmapData.hitTest?
