Ive just recently begun using bitmapData for various things, and I decided to create game around it. So Ive been working on this project for weeks now and for some reason i cannot fix this. Ok, so when I use the applyFilter(); Method it cuts my FPS IN HALF!

Anyway, I'm an animator and I've zero knowledge about AS. =( So, I want to ask, if you can explain following things: How can I change the glow and/or trail color? How can I tween this manually? Am I allowed to post request here actually? =P

I'm trying to do mouse trails in Flash MX, but having some problems. Tutorials are a little unclear. Do you first place your image or text on the main timeline and then actionscript or do you create a movie button, script that and drag onto stage?
View 5 RepliesI stumbled upon a tutorial from a few years back. It basically set up a rolling text mouse trail.I altered it so I could start the mouse trail with a button, but have yet to figure out how to stop it.
Here is the code:
Code:
on (release){
Text = "It's a mouse trail!";
letters = Text.split("");
letterformat = new TextFormat();
[code]....
In the tutorial it mentions the 'for loop' in the code. Does this mean I can not stop it once it starts? I hope not. I'd really like to give the user an option for turning off the mouse trail if they find it obtrusive.
I have some htmlText in a textField inside a MovieClip on the timeline. The MovieClip has a little (CS3) timeline motion tween on it - it grows and shrinks once. The htmlText is populated beforehand via ActionScript and the entire SWF sits inside a preloader "shell" that handles loading it and adding it to the displayList.
When the text expands - it looks fine. When it shrinks, the HTML bullets (UL and LI items) leave "trails" behind - and thus create a "streak". The funny thing is, if later on I move the playhead forward using gotoAndPlay(), the streaks disappear, even though it's not moving to a new keyframe for that MovieClip. So it's clearly a screen refresh issue.
I tried turning runtime bitmap caching on, and the bullets did not display whatsoever.

I have a simple AS class:
package Bubbles
{
import flash.display.Sprite;
import flash.events.MouseEvent;

Stage only has that green rectangle on it. If I remove it nothing changes. If I change line thickness to 6 trails does not appear, at 7 and higher they appear. You can check SWF here: [URL]. How do I make it work correctly?
Update: If I change that rectangle shape to something star-like with sharp angles, trails appear even on lower thickness values (trails appear when thickness == 3 or more).
i have an object on a motion path and want it to leave a solid trail of itself when it moves (no fade and stage isn't cleared)

I am having this issue with Flash CS5:After making an animation, I export movie as Quicktime. When I view this movie it?well I am not sure what it is doing. The animation leaves trails of color when an object moves across the screen, leaving behind little bits of color too. Is it lagging? This does not happen when I export a SWF, but it does happen when I export a Quicktime movie.I export using Quicktime, so I can then import it into iMovie, to add titles, and sound and others things, or perhaps I just want to add a little Flash movie to my iMovie project.

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:
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.
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 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?

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 am trying to serialize a Bitmap to store in an XML file. My plan is to turn the BitmapData into a byteArray, but I haven't been able to fine an example of this.
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?
