Professional :: BitmapData Objects And The GPU?
Sep 7, 2011Are BitmapData objects automatically GPU accelerated for rendering, rotating, and scaling,or does the bitmap they connect to need to have cacheAsBitmap set to true?

ActionScript 3.0 :: PNG To ByteArray To Multiple BitmapData Objects?
Sep 17, 2010is there anything that will take a very large png (even larger then the total pixel limit of BitmapData) and load in the png as raw bytes into a bytearray and then take that array and grab only portions of the image to be able to generate a grid of usable bitmaps to render the very large png..I got to the point where I was able to get the png as a bytearray but from there I don't know how to grab a portion of the bytearray and attempt to load the partial bytes in a loader via loadBytes()..basically I think I need a decoder to decode the partial bytes to a bitmapdata.

Apr 10, 2006How to dispose bitmapdata objects that have no linkage. The thing is that I have bitmap pictures (PNG) wrapped inside movieclips (as you can't set linkage to PNG files with jsfl) and when I begin to load them into my movie from the library I can't dispose of them to free up ram memory, i've tried to use movieclip.removeMovieClip(); and movieclip.dispose(); but the bitmap inside still takes up ram! I use over 1000 pictures so i really need to dispose them... How to get linkage set to PNG files with jsfl??

Feb 7, 2010I'm trying to know if you can copy the pixels of many objects in one BitmapData without a huge slowdown. The slow down is made by calling the method multiple times, thus making a lot of variable declaration and disposal for the garbage collector. If someone know how to either immitate the copyPixel method or have any other way of solving this problem,

Feb 2, 2010I have two BitmapData objects with alpha channels. I'd like to combine them into a single one by using max(channel_image_one, channel_image_two) for each channel, including the alpha. Is there an easy way to achieve this result?
View 2 RepliesActionscript 3 :: Merging Two Bitmapdata Objects' Alpha Channels?
Aug 22, 2011i have the following situation:
one drawing layer (graphics object with lineTo, etc.)
one png with an alpha channel (supposed to serve only as a mask)
now i want to be able to only draw lines within an area restricted by the png mask.
i am trying like this:
var bitmapData:BitmapData = new BitmapData( 320, 320 );
bitmapData.draw( drawingLayer );
bitmapData.copyChannel( maskBitmapData, new Rectangle( 0, 0, 320, 320 ), new Point( 0, 0 ), BitmapDataChannel.ALPHA, BitmapDataChannel.ALPHA );
now the borders get cut off fine, but i get a black background, since the drawing layer has an alpha between the drawn lines (and it should remain like this) and the mask bitmap has an alpha outside the shape. so naturally the mask's alpha replaces the drawing layer's.
i tried it with merge, copyPixels and also with just setting the mask property on the drawing layer (i set everything to cacheAsBitmap) but to no avail.
ADDITION:
when trying to use a mask i tried it with
<s:BitmapImage id="mask" source="@Embed(source='...')" cacheAsBitmap="true" />
and also as
[Embed("...")]
private const BodyMask:Class;
var maskBitmap:Bitmap = new BodyMask();
and assigned them to the mask property of a s:Group element (cacheAsBitmap=true) where the operations on the graphics object occured. i also tried reassigning the mask after each draw operation.
Actionscript 3 :: Why Do Loader Objects Kill Bitmapdata Draw();
Mar 27, 2012The code below is a simple add and save program. You press the addButton to add content to the canvas and than press the exportButton to save an image of the canvas in its current state to your desktop. This code works fine when I add circle objects to the canvas that are drawn to the canvas. The problem lies when I try to load a .png into the canvas. Once the loaded content is added to the canvas the exportButton stops working all together and no longer responds. What is causing the loaded content to break the code?

Flash :: Merge Multiple BitmapData Objects Into One So That It Can Be Encoded Using PNGEncoder?
Jan 30, 2012I am creating a program that is effectively an sprite creator. I'm very new to AS3, but I know JQuery, JS, PHP, etc. After going through multiple steps of selecting pieces to customize a character, you are supposed to be able to download the final product using fileReference(). Everything works, and I can download the image in the end, but the problem is that I cannot capture all of several movieclips on the stage, I can only capture one. Maybe this will help clarify:

Could it be that each of the movieclips I'm adding to the sprite have children of their own?
ActionScript 3.0 :: BitmapData's Draw() Method Also Draws Objects With 0 Alpha
Mar 17, 2011I am drawing a flash sprite on a BitmapData using its draw() method. This sprite has some nested objects with 0 alpha, yet the draw() method draws them on the bitmap data.
I think it has to do with the color transform I am using, but I have no idea how to change it to achieve the effect I want.
The color transform is the following:
Code:
new ColorTransform(1, 1, 1, 1, 255, 255, 255, 255);
I am using these values in order for the Bitmap to have white pixels wherever the object was, and black where there is nothing. The draw() also draws my alpha = 0 objects in white as well.
Actionscript 3 :: Two BitmapData Objects - Apply A Colorburn Or Darken Or Multiplay Filter
Dec 27, 2011Photoshop and Fireworks both have some nice filters. When you put one bitmap over the other, the first bitmap can act as filter. For example, the white pixels of the top bitmap lighten the pixels of the bottom bitmap. Is there any way to apply this in as3? What I am trying to accomplish: I have a large single-color bitmapdata object. I want to overlay perlin noise and lighten/darken the single-color bitmap to give it some random/natural look.

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

Professional :: BitmapData / GetPixel Mystery - Works Perfectly On Local, Failing When Uploaded?
Dec 13, 2010I'm working with a video in Flash where I am capturing each frame and testing the color of a single pixel. I'm using it to determine when a white/transparent background changes to be a color. The following AS2 code works flawlessly when I preview it in Flash and on my desktop in the browser (the direct SWF and placed inside HTML using SWFObject) but as soon as I upload it to my server it fails and produces "FFFFFF" continuously regardless.
this.onEnterFrame = function()[code]..........
There is no difference in the files; they are both pulling from the same video source (hosted on an Flash FLV server).The only difference is one set of files is hosted on my local computer and the other is hosted on my web server.

Professional :: Create A Visual Noise Pattern Using BitmapData.noise
Oct 25, 2010I have been trying to create a visual noise pattern using bitmapData.noise, and with help from Rothrock and Kglad have created a working version.I checked with a colleague who is expert on the use of these visual patterns, and he suggested that the change speed is too fast: that the dots (pixels) need to change at just under 400 dots per second for an 800 x 600 stage.With beginner skills in AS3, I am unsure if there is any way to change the script to slow the rate of dot change in the bitmapData.noise function?
View 2 RepliesActionscript 3 :: Graphic Object BitMapData Type The Same As BitmapData Type?
Dec 29, 2009The 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.
