i have a class thats create a class with bitmapData that merge 2 IBitmapDrawable. one of them is 24*20 while the other is 16*16.i want to draw the smaller first in a bitmapData object which its width and height are 24*20 but i want to draw it in the center of the big bounds.

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 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.
I'm making something that requires me to draw() the youtubeplayer Giving me this pretty error:

I'm trying to do some lean blitting for an object that rotates by rotating it once at startup and capturing a BitmapData snapshot of each 5 degrees. The problem I'm having is that the draw() method of the BitmapData object is only picking up pixels in the MovieClip that are below and to the right of the registration point. If I change the MC so that the registration point is in the top left corner, I sometimes get what looks like most of the pixels, but the entire object rotates into and out of the frame, since it's rotating around the corner and not the center.

View 2 Repliesthe problem may be a simple one but I can't figure it out. I have an image loaded into BitmapData. now I want to take text from a textinput and put it on the BitmapData. Basically it's drawing a text on the BitmapData and get the result as another BitmapData that will consist of the original BitmapData with the text drawn over it on a specified position

View 2 RepliesI have run into strange behavior drawing a sprite into a BitmapData. This sprite looks fine when drawn directly to the screen. But when this sprite is drawn into a BitmapData, the sprite is being masked... but there is no such mask applied to that sprite! This "bad mask" can be toggled off and on... by applying / not-applying a different mask to the sprite I am drawing. This mask is not the same shape or location as the "bad mask".

The documentation says that clipRect parameter of the BitmapData.draw method sets clipping for the source.Reading this I wrote an AnimatedObject class for my potential flash game. This class draws a frame from a .png animation strip, and doesn't work with Flash scene hierarchy.

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 am trying to copy an image.The green stuff on the first image is a mask(which is not set, its just there to show it)Everything works fine when I dont set a mask to an image (picture 1)But when I set the mask I get picture 2.What I want is to copy a part of the image which is visible when the mask is set. I know what size the mask and image are going to be so I can calculate the size of the area which i need to copy.This is the code I am using, image has registration point in the center, thats why i use matrix.translate (not sure if its the right way).Also there is no image scaling applied (there might be later), thats why I am using matrix.scale.

I have a sprite with some objects in it which are transformed in 3D (positioned and rotated). The objects form a coneshape in such a way that the objects that make up the back are hidden.When I use that sprite as a source for the bitmapData.draw() it is drawn from another viewpoint so it seems. In my case the copy is viewed slightly from the bottom and right.
Bottomline:Does anyone know of a way to duplicate the image of a sprite which contains 3D manipulated graphics?
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

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 trying to load a external swf and then use the BitmapData.draw() method to draw the loaded swf to a bitmap. This does not seem to work. If I draw some lines into the loaded swf using the .lineTo() method and then use BitmapData.draw() i do see the lines that are made by this method, but not the content i put in the swf. Is it just not possible to do this
View 1 RepliesI have a problem with strange memory allocation. I tried to illustrate the problem on a sample application, you'll find it in the attached zip file, or you can open this page: [URL] You'll also need something to see the memory currently allocated to flash applications - I use WSMonitor, please open it here: [URL] The code in the sample application is very simple. It does the following (please run the WSMonitor html, press "Start", and open the test page from above in another tab/window):
1. Download a file called "sample.swf". This is a swf file generated from PDF using pdf2swf tools, I'm sure you know this utility. The swf looks fine, it contains some images, but for some reason it causes me trouble - see below.
2. Once the file loads, I try to draw and display a bitmap representation of the loaded file, using bitmapdata and its draw function. So far so good. Note that I store the reference to the loaded MovieClip - I need it! Well not in this case, but say I might need it later.
3. Once the bitmap is displayed, you can click in the application. This should result in disposing of the bitmap. However, if I watch the memory allocation using WSMonitor, the memory usage won't drop down to the expected values - some tens of MB still remain. And that is the problem - say if I do this repeatedly with more swf files like this, I will have some hundreds MB of useless memory in my application - not cool.
From what I understand, the memory usage of this simple application goes as follows (let's say that after the start of my application, the usage is 0). After the swf is loaded, the usage goes to say +1 MB (reflecting the fact that I've downloaded some data). After the bitmap is drawn, the usage jumps to say +40 MB (why so much?).

I have been pulling my hair out on this one for too long. I have a web banner that uses Erik Hallander's Pixelator Class. Everything works fine when the timeline plays just once, but as soon as it loops I get error:
ArgumentError: Error #2015: Invalid BitmapData.
I have tried removeChild, removeEventListener, nulling the variables involved, disposing of the BitmapData. I also tried some conditional statements depending on the loop but no success. The actual class code is beyond my experience.
I'm using BitmapData.Draw to draw a masked movieclip to a bitmap.Flash behaves very strangely in many different ways. To give a couple examples:1) Normally, the position of the mask is relative to the masked object. Ex. if I Draw() the movie clip at 10,10 and the mask's position is 20,20, then during the Draw() the mask will effectively be at 30,30. Weird, but consistent. However, if I Draw() the mask to another surface first, and then Draw() the movie clip, the mask position will be absolute (20,20 in the example)

We have discovered that when we draw one bitmapdata into another bitmapdata using draw, there is an upper bound on the scaling transformAt some point the IBitmapDrawable parameter ceases to be rendered on the target bitmap.Does anyone know what the parameters of this upper bound are? Is this documented somewhere?
