ActionScript 2.0 :: Using BitmapData With MC That Is Already On Stage?
Jun 14, 2011
I'm working on a project that requires more than a simple hitTest. Bitmap collision seems the best way to go. My end goal is to be able to determine which side a rectangle was hit: top, right, down or left. If there is a way to do this with a simple hitTest I'd love to hear about it. The problem I'm running into while following the Flash Example with bitmap.hitTest is that as soon as I apply BitmapData to an mc that already exists on stage the collision detection stops working. I am wondering if this is an inherent issue and I have to rely on creating the movieclips via script then attaching BitmapData.
The Flash example is as follows, this code works correctly:
ActionScript Code:
import flash.display.BitmapData;
import flash.geom.Point;
var myBitmapData:BitmapData = new BitmapData(100, 80, false, 0x00CCCCCC);
var mc_1:MovieClip = this.createEmptyMovieClip("mc", this.getNextHighestDepth());
mc_1.attachBitmap(myBitmapData, this.getNextHighestDepth());
[Code] .....

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 am trying to grab part of stage area using BitmapData and copyPixels method:
bmd = new BitmapData(stage.stageWidth, stage.stageHeight);
bmdRect = new BitmapData(320, 240);
rectangle = new Rectangle(360, 20, 320, 240);
bmdRect.copyPixels(bmd, rectangle, new Point());
[Code].....
The result i get is an empty .jpg I m pretty sure that the error is in the Bitmap procedure and not the saving one...

I am copying a bunch of shapes from my stage to a set of bitmaps for filtering.
Is there a faster way to do this? Is there a way to copy everything over together from the stage rather than how I'm doing it by copying the shapes in my array one by one?[code]...

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:

//overwriting the first image. Do I have to somehow delete the data first, to

I am using the draw() method of the BitmapData to encode a jpeg of part of the image. Now this should be easy enough given the object I want to draw to the bitmap is on the stage at design time so I know its location and dimetions exactly! Heres the code I have in place.
Code:
var myBitmapSource:BitmapData = new BitmapData ( street.width, street.height, false, 0x333333);
myBitmapSource.draw(street, null, null, null, new Rectangle( 96, 5, 571, 450 ), true );
I know for a FACT that no part of the street clip I am drawing out is in negative space, and it's registration is (0,0). However, it cuts off A lot of the top of my image. y=5 in the above rectangle is where I need the top to be, but it cuts the top off of the image... even if I change it to 0, it has no effect.

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'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).
function stretch_blit(src:BitmapData, dest:BitmapData, source_x:int, source_y:int,
source_width:int, source_height:int, dest_x:int, dest_y:int,
dest_width:int, dest_height:int):void {[code].....

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?

What I've got is a NetStream object that plays video, and I want to be able to get a snapshot of the current data. Unfortunately, I have no idea how to obtain a BitmapData from a NetStream - it seems designed to be attached to a Video object, which through internal actions of the two classes ends up drawing the contents of the stream to the object. Using that - I initially did what seems dodgy to get an image - create a BitmapData object, and draw the contents of the Video object. This works, but it has a significant limitation: The data you get is tied to the Video object, and not the underlying source. So if your Video window is 320 * 240 for example, that will be the size of your bitmap data.
After some research, I thought of approaching it by making the Video object the same size as the underlying NetStream source - using the Video.videoHeight and videoWidth properties. If you know the size of the underlying data before you create the Video object, things are fine. You can just construct the new object with new Video(width, height). The frustrating thing is that the docs say you can change the width and height of a Video object after construction using the Video.width and Video.height properties, but it's not the same thing, since you also end up changing the scale.
how to either adjust the width or height of a display object without adjusting the scale(there was mention of a registration point in some of the docs I read), or failing that, a less roundabout way of taking a snapshot of data in a playing / paused Netstream?
