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?

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 am having an issue with using BitmapData.draw(stage). I am getting the following error:

I have 4 navigation button and like home, about us etc.... And i want to disable home when it is click and cannot clicked it until the user click another button first. means if a visitor is at home page then home navigation is disabled, and all other are active, and when they click at aboutus button then the pages goes to the about us page and the about us button is disabled and other get active. I want this solution in AS3 with oop concept.
View 6 RepliesI've got about 6 buttons laid out, one on top of the other in a list format. In their normal state the buttons are grey in colour, when I rollover them, the buttons flash and turn to orange. Now, what I need to happen is this: I want the buttons to stay orange once clicked and only roll out back to grey when the user has clicked on another button in the list. I've been told that the best way to do this is via adding a listener, however I am a little unsure as to how to go about this. I've checked the flash help file and have a basic understanding of how listeners work...but can't really wrap my head around applying it to this situation. Perhaps I will need to have all the buttons as separate broadcasters?

View 9 RepliesThe 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.
How can I make it stay the rollon color after it's clicked and then the rolloff color when another button is clicked?

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.
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?

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,

View 1 RepliesI 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?
View 1 RepliesI 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 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());
