Dec 22, 2010I'm trying to get my head round bitmapData and everything you can do with it. I'm using pure AS3 at the moment.I've been playing with some Perlin noise examples - worked ok - and tried writing another image (png) onto the bitmapdata.The new image is EMBEDed in the as3 code:
Code:
[Embed(source='icon.png')]
private var ImageClass:Class;
private var img:Bitmap = new ImageClass();
I write the perlin noise to the BitmapData thus:
Code:
var bmd:BitmapData = new BitmapData(200, 200, true, 0x00000000);
bmd.perlinNoise(baseX, baseY, octaves, seed, stitch, fractal, channels, grayscale, offsets);

ActionScript 3.0 :: Use The BitmapData.setPixels Method To Set Certain Pixels In The Bitmap Transparent?
May 2, 2009I am trying to use the bitmapData.setPixels method to set certain pixels in the bitmap transparent.But no matter what I do, it always seems to set the pixel(s) black (non-transparent).Here is my code:
[AS]
bmpd = new ImageFromLibrary(0, 0);
bmpd.setPixel(0, 0, 0x00000000);

why its not setting the pixel(s) transparent?

Actionscript 3 :: Calculating Evenly Distributed Points On A Line Of Points
Oct 3, 2011I have been tasked with trying to create a drawing tool that draws dotted lines as you drag the mouse across the stage. I can easily capture the points on MouseEvent.MOUSE_MOVE and store them in a vector and then draw the points as dots:
The problem is that I need to calculate evenly distributed points on an ever growing Vector of points so I can only draw the line between say every 5th point (say using modulus). I have been battling away with Bezier curve equations both Quadratic and Cubic but still can't quite figure out how to convert my Vector of points into an evenly distributed Vector of Points without sucking the life from the CPU.
IDE :: Can't Get CopyPixels() To Work?
Sep 26, 2009I did a function for blit scrolling successfully using Draw(), but then I heard that copyPixels is faster. Unfortunately, I'm not having the same success with that as I had with draw();
Specifically, no matter what I try to use for the source image, it keeps saying that it can't be coerced into a bitmapData object:
Code:
TypeError: Error #1034: Type Coercion failed: cannot convert SourceBitmap_bm$ to flash.display.BitmapData.
I tried referencing the bitmap in my Library (That's how I'd prefer to do it, copy from an item already sitting in my library) that has base class "flash.display.BitmapData", yet I get the error. I tried putting the bitmap into a movieclip and copying from that, same error. I tried copying from an offscreen instance of the mc (which worked fine with draw()), same error.
It's a mess by now because i've tried so many things, but this is my code:

I see are for copying pixels after loading in an external file. Does anyone know of an example that works with items already in library?
AS3 :: CopyPixels From A Huge BitmapData?
Sep 5, 2010I 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 RepliesActionScript 2.0 :: Using CopyPixels On A Isometric Map?
Aug 4, 2009How would I go about using CopyPixels to build an isometric map? CopyPixels takes a specific rectangle and copies that onto a bitmap.. But how would one use that to build a seamless isometric map?Building a square top-down tiled map would be very simple as copypixels pastes each tile next to one another.. But for Isometric Maps, this would be different as some parts of the CopyPixels rectangle is over lapped into other tiles.. and this would 'erase' the bitmap of the other tiles currently on the bitmap..[URL]Fig2, is what happens when you try to do a copyPixel over an existing bitmap, assuming the white is transparent space.
View 0 RepliesActionScript 3.0 :: CopyPixels Flip Or Rotate 90?
Nov 12, 2010Traditionally, when blitting in old 2d games, flips and 90 degree rotations could be achieved with almost no performance hit. The reason for this is that the effect an be achieved by simply changing the order that pixels are copied.
I'm using copyPixels in Flash to get maximum performance. Is there any way to do a flip or 90 degree rotation using copyPixels? (Without pre-calculating and storing the flip/rotate). I couldn't find a way to do it, but it seems like it should be possible, because it is a very common technique in 2d games (well, not so much now that modern 2d games use 3d hardware acceleration... but Flash doesn't let us do that, so we need to use the traditional 2d techniques)
ActionScript 3.0 :: Memory Leak During CopyPixels?
Mar 1, 2012I am making a custom renderer using the copyPixels function for my Haxe/Flash game. So I have this kind of code :
buffer.bitmapData.copyPixels(m_CurrentSkin, RECT3, POINT, null, null,true);
where :
-buffer is the bitmap where all my scene's objects are drawn
-m_CurrentSkinis the BitmapData that contains the current frame of the object to be drawn
Every time m_CurrentSkin contains a BitmapData that have never been drawn (the first time that an animation frame is drawn for example),I have a memory leak that is not garbage. However if m_CurrentSkin contains a BitmapData that have already been drawn (when the animation is played a second time for example), there isn't any memory leak.If I comment this line there is no leak so the problem comes from there.It seems that a copy of the BitmapData is cached in memory but I have checked in my code and there is no cacheAsBitmap explicitely set to true.

ActionScript 3.0 :: CopyPixels On MovieClip With Children?
Jun 14, 2009I'm working on my second flash game and have been stopped in my tracks trying to cache MovieClip Animations into arrays of BitmapData frames. To capture the frames I have set up a loop which runs through the frames in the MovieClip and use copyPixels to get a snapshot of the graphic.This works fine if the MovieClip to cache does not contain any child MovieClips, but if it does, these MovieClips are frozen on their first frames. I've been looking at MovieClip.getChildAt(index) in attempt to navigate their time lines but because that returns a DisplayObject it seems impossible.
So, my question is: Is it possible it to use copyPixes on a MovieClip and also step through child time lines, or should I be using sprite sheets?
ActionScript 3.0 :: Flash CopyPixels For MovieClip?
Aug 4, 2011I'm not much of a scripter. I get by editing scripts similar to my needs. I learned a few things about blitting and I'm trying to get a rectangle area of a MovieClip to blit to a location on the stage. But I run into the error "Invalid BitmapData" which makes sense because I'm referencing a MovieClip and not an image. Is there a different AS3 command other then copyPixels that would work for a MC?
I know VCam would seem an obvious solution, however VCam scales to fill the entire stage. I only want to fill a small rectangle on the stage. I've already attempted to edit VCam with no success. Its probably not the same principle, but would it be possible to blit the matrix VCam uses?

View 1 RepliesActionScript 3.0 :: Use CopyPixels To Copy Part Of Stage?
Dec 3, 2009Is it possible to use copyPixels to capture part of the stage directly into a bitmapData object?
Just wondering because in my situation using captureBitmapData.draw(stage, matrix); is causing performance problems, even without the matrix. I read that copyPixels is fast so I was wondering if there's a trick to use that directly on the stage without the draw part.
What I'm essentially doing is screen capturing a part of the stage and putting it in a a window, using a loop to update it over time since it contains animation. Works great in one of my FLAs, but chugs in the other so looking to optimize the code to a bare minimum.
Flash :: Set CopyPixels To Ignore Transparent Pixels?
Mar 17, 2011I have a BitmapData object with transparency (the sourceBitmapData parameter). Every time I use copyPixels() to copy it onto another BitmapData object the transparent pixels replace whatever is beneath them. I would like the copyPixels() function to simply ignore these fully transparent pixels (0x00) and NOT copy themBTW, I've tried setting the alphaMerge to true but that doesn't solve the issue - the whole source object just goes black and ignores ALL transparency.EDIT:
Here are the code snippets;
var b:UIComponent = new UIComponent();
b.graphics.beginFill(color, opacity);

ActionScript 3.0 :: Flash BitmapData.copyPixels And BlendMode?
Oct 4, 2010I'm loading a batch of 50 jpgs and once loaded, on enter frame, I'd like to change their alpha individually and apply BlendMode.ADD to all of them (also individually).
I can do this easy using normal Sprite objects, but this is not efficient enough (processor wise). I've played a bit with BitmapData.draw(source, null, null, BlendMode.Add) and that's still not efficient enough.
So I was wondering if I could achieve similar effect using copyPixels (which I know should be more efficient). Still, I'm a bit clueless on how could I apply BlendMode and alpha on a bitmapData object (I mean, I know I can't, but I was wondering if I could make this work using Matrix and filter manipulations).

Flex :: - First Window Width/bound Gets Ignored?
Mar 31, 2011I have a window in which I want to add/remove component and resize the window accordingly based on states. but for some reason it's ignoring the first resize.here's a sample code
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
[code]....
when the state change to 'two', I want to add rect2 to display and increase the minWidth and size of the window. And when the state change to 'one', i want to remove rect2 from display and resize the window. This seems to work except the window doesn't shrink on the very first time the state change from "two" to "one" but works as expected afterwards. I'm not sure why it's ignoring first time I reduce the width. I also tried changing nativeWindow.bounds directly but that didn't work either.
Originally I just tried setting minWidth based on state (minWidth.one="450 minWidth.two="791") but that caused window to grow on left and shrink on right which caused the window to move left whenever the state changed. so then I just moved the window to right whenever state changed but that caused some flicker that I didn't want.
