i've used a Loader and URLRequest to download a .png from the internet and add it to my display list. since it's already a bitmap, does it have built in bitmap data already? or do i have to create the bitmap data myself? also, why does the same trace statement return false in the mouseMoveHandler when it outputs true in the displayIma...
I'm looking for an efficient way to filter a specific color from a bitmapData object in ActionScript 3. Currently I use a loop with readByte32(). This takes about a second to process which is unacceptable. I have been trying to get paletteMap() to work but so far haven't been able to grasp its API (any truly useful links? Google has ...

If I take its snapshot using : var bmd:BitmapData = new BitmapData(width,height); bmd.draw(someSprite,someMatrix,null,null,null); I get an image like this : Click here to see the image In this image, I have added the green boundary myself, just to ...

What is the best way to do so? ...
How can I convert a WPF WriteableBitmap object to a System.Drawing.Image? My WPF client app sends bitmap data to a web service, and the web service needs to construct a System.Drawing.Image on that end. I know I can get the data of a WriteableBitmap, send the info over to the web service: // WPF side: WriteableBitmap bitmap = ...; in...
I have small function which will recolor pixels in a Bitmap from a given color to a new given color. The problems I have with the code are as follows: 1) The function gives results which are remapping white pixels which should not be concidered since I have a threshold... (unless I have defined this calculation wrong) 2) When certain ...
Hi I have a bitmapdata object that is filled with n rectangles of a width of 1 pixel and of varying heights. I want to run through a loop and remove the old rectangle and replace it with a different one. Should I do something like reset the each bitmap column of pixels to a background color and then add the rect i want? for(i:int=0;i...
Hello, I'm playing around with the GLPaint Example from Apple. But I don't know how to create an effect which fades the already drawn stuff out. I created an example in Flash which shows the effect I'm looking for: http://staging.rwichmann.com/openglexample/ In Flash I'm drawing a texture on a BitmapData and in every frame I'm adding ...
Hi everyone, Interesting problem here - I'm making a small game using Flex 3 - now I have a static ImageAccess class, which first loads up all images and stores them in a static array for quicker access in the future. Now since I address the physical bitmapdata without calling Clone() (for efficiency issues) and once by accident I've wr...

Is there anyway to load ...
I 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 ...
I am trying to use BitmapData.draw() on a video object, but using the OSMF framework. My hosting service has set up the following so that I can access my rtmp video: <VideoSampleAccess enabled="true">/</VideoSampleAccess> Simplified code is as follows: _videoURL = "my-url-here" resource = new StreamingURLResource(_videoURL)...
In Flex, how does one hook into a bitmap or bitmapdata variable so that a function is notified whenever the bitmap's data has changed (pixel has changed, or filter's been added)? I tried setting up binding but it doesn't work. There must be a way to do it, because I can bind an mx:Image to a bitmap via the 'source' attribute, and the...
Hello, I have a bitmap image and a byte[]. The byte[] contains an effect such as noise (in my case, byte[] contains custom effect). I want to apply this byte[] effect to the bitmap image and save the resulted bitmap. I have the BitmapData and byte[] but I don't know how to mix merge these together? Thanks Update: Well the byte[] con...
Hello, I've run into an issue where the BitmapData.draw() method isn't accurately subtracting image data from a .png that uses transparency. I've put together a test file that shows this behavior, it's located here: http://www.filedropper.com/shield_1 In a nutshell, a sprite drops from the top of the screen and when it intersects with...
