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??

I'm converting some code form C++ to AS3 ... and in C++ have so called Modal window ... lets say we have an function in C++ like this
Code:
CYESNO m_yesno=new CYESNO();
if(m_yesno.DoModal()==IDYES) {[code]....
a know that this can be achieved with events, and with breaks the code into several functions ... but i don't want that ... i want to keep things simple.just when i call CYESNO m_yesno=new CYESNO(); the code stops and after selecting an option, then code continues to execute from corresponding if() block in the same function.i thought that nested functions will help me but unfortunately i was wrong.Or not ?

I'm using Flash 8, with this code in the first frame:
import flash.display.BitmapData;
rissa._x=Stage.width/2;
rissa._y=Stage.height/2;[code].....
When I publish the file, I'm getting the following error message in the Output panel:

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:
ActionScript 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.

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 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

When I use it, the only thing that is filled is a white rectangle, doesn't matter the parameter.This is what I do:var map:Bitmap = new Bitmap (new BitmapData(200,200))map.bitmapData.fillRect(new Rectangle(0,0,100,100),0xFF0000)A 100x100 rectangle is added to the bitmap, but it is always a white shape. I want it to be red, as set in the parameter (0xFF0000).

I am trying to take a snapshot of the masked region of an image... so, I load my image then perform the following functions:
private function manageLoadedImage(e:Event):void
{
_bitdata = e.currentTarget.content; // get the bitmap
_bithold.addChild( _bitdata ); // add the bitmap to a sprite on the stage
[Code]....
I have a movie, inside that movie I have a thumbnail editor name ThumbEdit.
ThumbEdit has a movieclip on its stage called "holder1". In the document class of ThumbEdit I create a sprite "_bithold" and place it on the stage at holder1.x and holder1.y. When the image loads, I add the image to _bithold and then mask _bithold with a shape. So, I want to grab a snapshot of the masked region of _bithold but I'm not sure how I should go about doing that.

I have a bitmapdata object that is filled with n rectangles of a width of 1 pixel and of varying heights.
I want to run through a loop and remove the old rectangle and replace it with a different one.
Should I do something like reset the each bitmap column of pixels to a background color and then add the rect i want?

I'm currently loading a remote swf through as3 (with a domain policy to allow all from that domain - the policy file can't be changed by myself), that i want to take a snapshot of. The problem is that the main swf that i load, is loading child swf's from another domain that does not have the allow all policy turned on.. This makes the snapshot feature call a "sandbox security" error. I'm wondering if there's an alternative to the bitmapdata draw function to still take a "snapshot" without conflicting the sandbox security.

I have converted a PNG into a bitmap, then converted that into bitmapData.
I have a object called _player, and I wish to add collision detection, however I can seem to get it to work.
my code is:
if(bmd1.hitTest(new Point(_player.x, _player.y))){
trace("hit");
}
bmd1 is my bitmapData,_player is the object is wish to test against.
I am getting the following error:
1136: Incorrect number of arguments, Expected 3
I have looked around but cannott find what argument I am missing
I have tried
if(bmd1.hitTest(new Point(_player.x, _player.y), 50, _player)){
trace("hit");
}
I should mention that the reason for me taking this approach is that I have a PNG, with transparent areas, I need to test for collisions in the non-transparent areas, which is why I was using this approach
I have a PNG, i import that and convert to bitmap, then convert to bitmapData

Both doesn't work, which puzzles me. The first one worked without encoding it in any way, so I don't get why it doesn't work when I try to just call it like that.

I am using NetStream.appendBytes() to play a local video (no server involved) in Adobe AIR. I would like to use BitmapData.draw() to take a picture of the video output, but I am getting this error:
Error #2123: Security sandbox violation: BitmapData.draw: cannot access null. No policy files granted access.
Here is some sample code:
package
{
import flash.display.Sprite;
import flash.filesystem.File;
[Code].....
This is only sample code use for an explanation. The error would happen when calling the getImage method while the video is playing. The error mentions a policy file not found. Since the file is loaded locally there isn't really a place to put a policy file. Is there a policy setting somewhere that needs to be set or is the BitmapData.draw feature just not available when using appendBytes?

I am writing a screen scroller for a game I'm making. There's a BitmapData object which holds the background graphic, yet I do not want to show/render it on screen all at once.
For example, I want to show only a 500x500 section of the data but the entire BitmapData is 1000x1000. I wanted to use the scroll() method to scroll the data but my problem is that I cannot restrict how much of the BitmapData is drawn on the Bitmap. I tried setting the height/width properties of the BitmapData to 500x500 (and draw all the 1000x1000), but any data drawn beyond the boundaries I defined is not really drawn.
Another option I considered is to store a different BitmapData object which holds the entire data, and then use copyPixels() from it to the one used on the Bitmap itself, although then I cannot use scroll() and have to use different methods to achieve scrolling.
