Actionscript 3 :: Quickly Rotate The Pixels That Make Up BitmapData Without Using BitmapData.draw()?
Dec 29, 2011
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 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 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.

im trying to draw opaque pixels on a transparent bitmapdata background
heres the ex:
ActionScript Code:
//TRANSPARENT BACKGROUND
var _pixelColor:uint = 0x9998002E;
var _bmpd:BitmapData = new BitmapData(4, 7, true, 0x00333333);
[Code].....
This example paints 2 arrows, the first is using the transparent background, and the second is using an opaque background on the BitmapData.
What I'm trying to achieve is to paint the pixels of the arrow completely opaque on the transparent background. But as you can see, the pixel is at 99% of its opacity (var _pixelColor:uint = 0x9998002E) How can I paint 100% opaque pixels on a transparent BitmapData "canvas"?

I wrote a collision detection class that works off using BitmapData.hitTest. Basically, every update, the .draw method is called and then two BitmapData's are hitTest'ed against each other to see if there is a collision.It works pretty well, however if I start rotating the source MovieClip I use for the BitmapData, the transformations don't get registered in the draw method. So what I did was pass through a Matrix in the draw method. That works. But here's the actual issue. If I output the BitmapData to a Bitmap on the stage, I see that Bitmap is, in fact, rotating, but now it's exceeding the bounds (width and height) of the BitmapData. Which is cropping / clipping the image of the source MovieClip.
UPDATE: Basically, when the Bitmap clone of the MovieClip rotates outside the positive co-ordinate space, it doesn't get drawn. It rotates outside the bounds of the BitmapData set width and height. I can multiply the bounds by 2, and then center the bitmap inside the set bounds, but then the origin point is never fixed and the object is always being moved around. Works pretty well, but makes aligning the object to any specific point impossible.Here's my isolated test code. It requires you to have a MovieClip on the stage named "iTest". I used a fairly vertical arrow shape (higher than it is wide) so I could keep track of rotations visually accentuate the clipping problem:
var rotateTimer:Timer = new Timer(10);
function rotateObject_init():void
{

I got serious issue while using adobe flash media server (I have media server streaming license). It doesn't allow flash clients to make stream's screenshot (with BitmapData.draw) because this is restricted from server side by default. I found that this trouble can be resolved my updating main.asc file but it seems like replacing main.far with mine main.asc causing error. Could you please help me with resolving this issue because it's extremely important to allow this screens making for user.I used CentOS 5.3 and FMS 4.0.1 r2009 (instaled in /opt/adobe/fms include Apache 2.2). All video is stored in a directory /opt/adobe/fms/applications/vod/media and I put the main.asc file in the directory /opt/adobe/fms/applications/vod/ from the directory /opt/adobe/fms/samples/applications/vod.

I'm trying to create a BitmapData object from a movie clip, but I need to also get the pixel data in a layer that has been set as a mask in the authoring environment. All I'm getting is the masked in pixels, but I also need the mask itself, and I'm can't seem to find a way to do it.

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 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.

I need to create, from a given Bitmap/BitmapData of a PNG file which has transparent and semitransparent pixels, another BitmapData which is a copy of it, but all the pixels (well, the pixels that are not alpha 0% actually) must have a specified grey color value (0xdddddd).

Let say I have a BitmapData with different pixels representing an object, and some black pixels around it that I want to remove.I would like to obtain a new BitmapData, with width and height of the object represented by non-black pixels.For example, let say I have a BitmapData 400x400px, but the object represented by non-black pixels occupies the rect: x=100, y=100, width=200, height=200. I want to get new BitmapData representing that rect, all black pixels should be removed. Of course, i have no coordinates for that rectangle, i need somehow to make difference between a full black bitmapdata and the original one, and construct a new bitmapdata (different width and height).

I have a map (map of a mall, top view) with some colors. I´m removing the part for walking of the map, which has a type of color (say 0xcccccc).
I got all the 0xcccccc color pixels removed (setted to another color), but it seems to remain a bit of gray at the walking part.
The color of that bit it´s close to 0xcccccc. It looks like flash not succeeded while removing the walking part. But instead, leaved some parts (like borders or something) on the bitmapdata.
I´ve tried to remove by script, by picking the colors remained on the bitmap, but the loop doesn´t find these colors.

What I have setup right now is one movieClip that is being used to be drawn into a BitmapData object. That bitmapData object is being drawn on the enterFrame and I am needing to clear it so it doesnt have the previous enterFrames information still stored in it, then once it is clear draw the current information. Is there a simple way to clear or erase all the pixel information in the BitmapData object?
If there is a way to set the alpha of the pixels I would really like to know how that is done as well. However, I want to change the alpha level of the entire BitmapData object, not just a few pixels.

I have a list of images, and without scanning through each pixel in each image, I want to find out if the image contains transparency (at least one non-opaque pixel).Is there a shortcut to do this (like a property of bitmapData object) rather than looping through the pixels?

Having trouble trying to scroll BitmapData on a half pixel here is my original code
var speed:Number = 1;
_bitmapData.copyPixels(_backgroundParallax, _screenRect, _zeroPoint, null, null, true);
_backgroundParallax.copyPixels(_backgroundParallax, new Rectangle(0, 0, speed, _backgroundParallax.height), new Point(_backgroundParallax.width-speed,0), null, null, false);
_backgroundParallax.scroll( (speed*-1) , 0);
which works until i change the var speed to .5, which is because .scroll method is expecting int's so i replicated what scroll is doing to try and allow .5 pixels

I am using bitmapData and bitmap classes to render a mouse cursor on the display screen. The bitmapData consists of an area whose colors should be inverted according to the background color. This is a very basic thing which could be observed with text cursor(the vertical line with two small horizontals on top and bottom), when moved over the text area. want to be able to do the same with the pixels in my bitmapData, is there a way to find out the background color effectively and invert the color values? In this process i will be redrawing the whole pixels, is there any other efficient way to do that ?

I am trying to use the bitmapData.setPixels method to set certain pixels in the bitmap transparent.But no matter what I do, it always seems to set the pixel(s) black (non-transparent).Here is my code:
[AS]
bmpd = new ImageFromLibrary(0, 0);
bmpd.setPixel(0, 0, 0x00000000);
[/AS]
why its not setting the pixel(s) transparent?

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..

the 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

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.
Code:
var _reflectionHolder:Sprite = new Sprite();
addChild(_reflectionHolder);
_reflectionHolder.y =_targetObject.y + _targetObject.height / 2 + 10;[code]......
