ActionScript 3.0 :: Convert A Drawing API To A Bitmap At Run Time?
May 5, 2009
Over the weekend i put together an MP3 player in Flex and just managed to figure out the SoundSpectrum.
It is working as expected.
I am facing problems when it comes to using a bitmap.
Right now, my "Analyser" class pulls the data from SoundMixer.computerSpectrum.
I then use that data with the drawing API to create a simple analyser. You know, just spikes.
Here is the code for that part:
Code:
private function update(e:TimerEvent): void
{
SoundMixer.computeSpectrum(ba, true);
var n:Number = 0;
[Code]....
Ok using common sense here, I am telling flash to take a snapshot of the Analyser and draw it to the bitmapData.
However, i cant seem to get this working. I am not using the dispose() method to clear the bitmap so id expect to see a mess of points (similar to if i removed the g.clear()) but nothing happens.

I'm making a game where the player moves around a map, where the player can walk and where they can't is decided by the color of the pixel they are trying to move onto, which I get using the Bitmap.getPixel method.
What I'd like to do though is when the map image is loaded process it into a sprite or something which I can then use the DisplayObject.hitTest methods on. So I have an array of colors whcih the user can walk on, is there way I could go through each pixel and build something that would let me do that?

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
import flash.display.Bitmap;
import flash.display.Bitmap;[code]......

what i need to do is basically a motion trail on a bitmap.
I want to continuously draw a bitmap onto itself while previous versions are faded into the background, similar to a smoke type effect.

today i started some particle generator class that will move particles over the stage via drawing in a Bitmap. Everything works well with low amount of particles, lets say 1000, but for my surprise when i added 10 000 particles the frame rate dropped drastically. And i am saying that since i made the same particle generator using MovieClips instead of drawing in Bitmap, the performance test i run on both classes showed that the Bitmap class with 10K particles on my PC works in around 10-12 FPS, and the MovieClip variation in around 20-21 FPS with the same amount of particles. The particles are identical and both classes are using linked list system to move the particles. So the only logical conclusion is that something is not right with the drawing function.
Code:
private function drawParticles(e:Event):void{
// clearing the _pZone Bitmap of the previous data
_pZone.bitmapData.fillRect(_pZone.bitmapData.rect,0);
_pZone.bitmapData.draw(_blankMc);

Basically, I have a BitmapData object which is acting as a virtual screen.
I have a MovieClip which I want to render to the bitmap using the same transformation as though the bitmap were the screen. However, the MovieClip is not attached directly to the root
The BitmapData.draw() method takes a Matrix as an optional parameter, which I think I need to set as the MovieClip's localToGlobal transformation matrix. However, I don't know how to obtain or construct this!

As the heading dictates, i want to place bitmap files on the faces of the 3D object that i have created.Basically i found this tutorial code on a 3D rotating cube that is able to be rotated by the mouse. I have modified it to change its shape from a cube to a 'plane' or rectangular style object.
Code:
var vertsArray:Array = [];
var facesArray:Array = [];

I'm trying to use a bitmap fill, but I can't seem to get it to work.I'm using FlashDevelop with assets imported from CS4 - this isn't the problem, I can instantiate the asset I'm targeting perfectly fine, so I suspect that it's a problem with what I'm trying to do. Here's my code:
Code:
//get the bitmap data from a grass symbol
//grass symbol IS present - can be added to stage fine
var grassBMD:BitmapData = new BitmapData(155, 80);[code]....
Nothing gets displayed in the box, so I'm suspicious that I'm not allowed to use bitmap fill in non-primitive shapes.

I have a project that is drawing ~10,000 small tiles into one large bitmap container - it's a mosaic. In Flash proper and in FireFox it takes about 20 seconds to complete the drawing. Very acceptable. In Chrome it takes about 1:30 and in IE it takes roughly 3:00 - both too slow to be acceptable to the client - who of course reviewed with IE. I have Flash set to run at 45 fps - and the images are populated by a Timer - at 2 ms intervals. Maybe 2 ms is too fast? But in my testing 1ms was slower as was 3ms, so I kept it at 2. And it works fine in FF and Flash...

If I draw a rectangle or trapezium, how might I go about drawing bitmap data into that shape? I need to give a slight perspective to a loaded photo. Native 3D rotations seem to leave the bitmap really blurry, and a full 3D engine is too heavy for this project.

I've written a class that iterates through all the frames of a movie clip and draws each one to a different bitmap. When I'm done, I should be able to iterate through the bitmaps and play them like a flipbook animation.If I draw all the clips to the same size bitmapdata, then everything looks great. But this is wasteful because now a lot of the bitmapdata's are bigger than they need to be (takes up more memory), and also causes problems because the hit tests don't look right.
So next I try to crop all the bitmapdata to be the smallest possible sizes. However, when I do this, there are subtle differences in the way the images look - the edges might look slightly darker in one frame than in another. When I line up all the images and play them back to back, it no longer looks the same way it originally did.I have no idea why the images look different, and have no idea how to work around this problem, I have tried many different approaches. I have tried using BitmapData.draw(), BitmapData:copyPixels(), and manually using BitmapData:SetPixel(), and all end up with the same result

if it is possible to covert a bitmap to a Sprite? I tried casting it to a sprite, but that does not work. The reason why is because if figured out that you can't use the addChild option on a bitmap.

Apparently, in order to make a bitmap transparent, one has to convert it to 256 colors from 24. I'm not sure if Flash puts it in 24 or 256, but because I can't create a transparency when using Bitmap() in my code, and from what I see displayed on the screen, it would appear that it uses 24 colors. Perhaps this is to keep things light. Nonetheless, is it possible to convert it to 256 colors?

when i try to doing the following code it fails
bmd.setPixels(bmd.rect, decodeValue);
and the error message is: Error: Error #2030: End of file was encountered. The situation is i have store the image as binary into the database by convert the byteArray and now i would like to retrieve it and convert back to image.
Just to clear this up ByteArray Need to Place into Bitmap and then you can add to the movie Clip right?

I'm building an XML driven video player that will allow users to customize a wide variety of layout/visual features for the player, and one of the important features is letting them switch between a regular background image, and a tiled background. I've been playing around with various methods for tiling using the Bitmap class, and its been working fine, as long as I load the image from the library. However, when I try to load the image dynamically (i.e. through XML), it doesn't jibe.
Here's the code for the tile:
function tile() {
var tile:BitmapData = BitmapData.loadBitmap("linkageIDForBitmap");
this.beginBitmapFill(tile);
this.lineTo(Stage.width, 0);
[code]....
Again, if I write a variable which references the xml node, and use that variable in the loadBitmap function, it doesn't work. I'm assuming this is because the dynamically loaded tile doesn't have a linkage ID attached? Not sure how to do that...
My other thought is to simply load the tile into a movieclip (as I do with all the other content), and then convert the movieclip to a bitmap, then proceed as normal with the code above. I've searched the boards for a method to do this, but have come up empty.

I am having a few issues converting a MC to a bitmap. I have succeeded in loading a graphic from the library, loading that as a bitmap and I can use getPixel to get the color at a certain x,y point.BUT I have another part to the problem. I have a file upload where a user can upload an image and choose a color off that logo. So I have the logo uploading, then getting loaded into an MC on the stage and it all works honky dory.However, when I (thought) I was converting it to bitmap and then use getPixel, every part of it is just returning white.[code]But no matter what co-ordinates I put in, I always get white.

var myBitmapData:BitmapData = new BitmapData (612, 792);
myBitmapData.draw(STData_mc);
bm = new Bitmap();
bm.bitmapData = myBitmapData;
stage.addChild (bm);
these are my code. I have a movieclip named STData_mc, first I want to use var myBitmapData:BitmapData = new BitmapData (STData_mc.width, STData_mc.height); but it bring me an error. so I changed like this. but this is ok. Finally, when I add "bm" to the stage, there is nothing, just a white space.
