ActionScript 3.0 :: Flash Bitmap Scrolling?
May 25, 2010
I have read all over the internet, but could not find any solution.I have large bitmap background (800X600), which I need to scroll. When I scroll it, it becomes "jumpy", pixels shifts, all lookes blurred.I've tried dozens of stuff:Playing with pixelSnapping.Setting cahes. Blitting Bitmap firstly.Adding smooth.Cutting background into small 100X100 pieces and putting them together.Setting crazy FPS.using scrollRectAnd all different combinations.Am I trying to do something unavailable from start? Is flash rastor enginze that limited, that my only choice is to use vector graphics for scrolling smoothly

For a fullscreen AIR app, I want to have a tiling image (JPEG, PNG or whatever) in the background. The app is displayed on large screens in a public building, and to achieve a cool effect I want the background image to "scroll" infinitely, with the direction of scrolling changing with an interval in time. The background must be tiling and always filling the screen. Performance is of importance.What would be the best approach for this? I am thinking toward pixel-level bitmap manipulation. I have no experience in this field and I can't find any good examples/tutorials online.

This is a repost, but I've still not figured out a solution. I have a Flash movie that appears on a webpage. The Flash contains scrolling content ( scrollpane, text field, whatever).
The containing webpage is tall, and therefore also has scrollbars. My Problem: When users try to use the MouseWheel to scroll through my Flash scrolling data, the browser page scrolls as well. It's very annoying.
I would like to be able to have the MouseWheel scroll my Flash scrolling content when it's over the flash, but scroll the webpage when it's not over the Flash.
Does anybody know a way to supress wheel-based browser page-scrolling while my mouse is over a Flash movie??? Is there a way to eat/stop propagation, whatever, of the wheel event in the brwoser, either from Flash or from Javascript?

I'm cutting my teeth in actionscript 3 on a game that has a character running through a world. So, I have set up my Hit Testing by using the bitmap data hit test method, since I figured my world is going to be destructible - it'd be nice to update the level and then redraw it and have the character interact with the new change. (That works beautifully) I am however; a bit confused as to how I have my hit Testing set up. I've been messing around with it, and it works for now - but I'm not sure why.. currently, I have a character set up by using a class I built and using a series of animations I created. So, this character has a walking and falling animation, etc. This is a movie clip.
Then there's a bitmap 'emptyBitmap' with bitmap data created - however; I never really added this as a child to the character. This is sized to the dimensions of my character. My level is created as a movielip, then it's drawn to a bitmap - when the level movieclip is changed, the bitmap redraws, and that's how this updates.

I know the topic of "duplicating" movieclips is a hot issue with the new virtual machine. Luckily, I understand the implications. I only am [currently] interested in duplicating a Bitmap. See, I load an image from an URL using 'flash.display.Loader.load', which is a non-blocking operation in Flash Player.However,I may use multiple copies of the loaded image (which is reported to be a Bitmap, naturally) in the display list at the same time.Hence, I naturally do not want to load the image from an URL every time, because I don't want to wait for a non-blocking call to complete. Nor do I need to - I mean one copy is already loaded, so it should be possible to just "duplicate" it, right?
My idea is to do use the bitmapData property of a Bitmap and pass it to the constructor of a new Bitmap object. I have not tried the following in action, but I want to hear whether any of you did and if the following would not work, what would:
Code:
var original_bitmap: Bitmap;
var copy_of_original_bitmap: Bitmap = new Bitmap(original_bitmap.bitmapData);
LiveDocs mention that the BitmapData being passed to a Bitmap constructor is "being referenced", which to me might suggest it cannot be used twice? There is also the BitmapData::clone() method, which I am not sure is applicable here or not.I know this is a lot of talk instead of just trying this out, but I test so much Flash Player code daily just to see "what works" (which should be documented instead by Adobe),

If I have a BitmapData that's already been drawn onto a Sprite. Is there a way to redraw the BitmapData onto a Sprites Graphics object without having to invoke beginBitmapFill and passing in the same BitmapData?

I'm working on a game, and to keep performance good, instead of addChild'ing 50 new sprites to the stage every second, I decided to have each player draw to their own bitmap, and then to the 'master' bitmap. This introduces an issue though: the second player would override all data the first player has put into to bitmap...My basic debugging proof of concept:
Code:
// bitmap test

I have a bitmap which has several frames (packed along the horizontal axis). In order to render them I copy it to the backbuffer (larger bitmap) as follows:

public override function copyToBackBuffer(db:BitmapData):void{ if (active) var drawRect:Rectangle = new Rectangle((currentFrame-1) * frameWidth, 0, frameWidth,

In pure AS3, I have a pixelbender and a large bitmap. The pixelbender is configurable with a distance parameter to affect only a small area of the bitmap.

Is there a way to write a bitmap font right into the bitmap being desplayed? Mabey better worded: myBitmap.draw(image, t) draws a picture is there a way to draw text? I'm stuck even if its just a work around in some way I would like to know... (the current work around i have in my head is writing it in a movieclip turning that into bitmap data and drawing it... esentially creating a prototype answering my question... but a built in way would be easier probably).

In AS3, I am loading a png from a zip file (nochump's zip library through ByteArray to Loader). The png can be up to 45k pixels wide but only 120 tall. This creates a problem in flash, as images can only be ~8000 pixels wide. A possible solution would be to split the images into 6 columns somehow. This would probably need to be done in the ByteArray state, because the limitation is in Bitmap and Loader.

I'm using Sandy to animate some objects in 3D. What I currently do to images which are EXPORTED in the library, I want to do to some bitmaps that I create using the DRAW technique. But it wont work :-(
CODE FOR 'CREATED BITMAP' :
ActionScript Code:
var bData:BitmapData = new BitmapData(myObject.width,myObject.height);
bData.draw(mask5);
[Code]....
Sandy doesn't seem to treat the 'created' bitmap the same as those that are exported from the library.

I have a spark List with an item renderer and a tile layout. If I scroll by clicking with the mouse on the scroll bar and trying to scroll with the mouse wheel after that, there is a problem: The interval of the scrolling is oversized, instead of scrolling one item down (or up) the List scrolls 4 items down (or up).

I haven't worked very much with bitmap manipulation and I need to create an app that can find a bitmap (or a pattern of pixels really) in another bitmap.Are there other methods of doing it besides iterating through the pixels and using getPixel()?I'm of course looking for the most effective solution.

Is it possible to add my own custom property to the flash.display.Bitmap using a public static method? I'm trying to write a bitmap utility that does something to a bitmap, and stores a Number property onto it afterwards.
[Code]....
I'm still learning AS3.0 OOP, I think that this can't be done with this method. I think I have to make a new Class that extends 'Bitmap', add the prop there, and then in the Main.as make a new instance of that class, point to the target Bitmap, and run the method in the extended 'Bitmap' class (?).

I'm trying to make an online TCG and I'm starting out by creating the table and card stacks. I've set it up where I have a table which holds stacks. The stacks hold cards, and the cards hold a front and back image. Really simple. So I thought. For some reason, the card is re-sizing to fit the screen. Even though a trace shows that the width and height are correct. Here is an example:n all reality, it should be about the height of the white box with the "A" in it, in the top left hand corner. The only place where I explicitly set a width and height is setting the table width and height. The table, Stack, and card are all sublasses of the flash Sprite class. Since there are 4 seperate files for the example above, if someone would need to look at the code,

I'm using a 3800x3000 bitmap as a background of a game.
Now, I first show the whole bitmap - the landscape -, and than zoom in at the characters. I'm using TweenMax from GreenSock, but even with this advanced tween class my bitmap doesn't move and scale smooth.
I'd like to work with smaller bitmaps too and scale them, but than I'll lose the quality, and I can't blur the bitmap to hide the quality loss, since there's a terrain in the bitmap too, and I don't want to blur that.

I'm doing a simple bkend admin using php for the client to upload images to be displayed on their flash website. ideally if they upload at the correct size, no problem, but sometimes they don't. So my problem comes in when the uploaded images are very big. When they are scaled down, the smoothing makes no difference at all.
I was wondering if there is a work around?
Code:
import flash.display.*;
loadMcListener.onLoadinit = function(){
var bitmap = new BitmapData(mc._width,mc._height,true,0x000000);
