I came upon a really nice class that loads a pixel bender filter and applies it to an image, but so far havent really managed to call it to from within a different flash application.

Does anyone know why this code won't work in Flash Player 10, yet it does in the Pixel Bender Toolkit?The output is that there is no change to the movieclip I attach it to.I have verified that I can get other pixel bender filters to work.I can even do other things like force outPixel's channels to specific values.[code]
View 2 RepliesHow to stretch out the movie clip to twice its width and height after applying some Pixel Bender filter? I have some object with video on it (for ex 512 by 512) I apply a Pixel Bender Filter on it. Now I want to stretch the result (for ex to 1024 by 1024). How to stretch it?So my point is 1) Render the result of effect2) Stretch out the result

Changing HUE_MAX slider in app (binded to MAX_RANGE parameter of filter), it doesn't filter out HUE values smoothly, but instead thresholds at HUE_MAX=59.9, where at lower values looks like no filter is applyed, and at HUE_MAX=299.9 where between 60 and 299.9 looks like this: [URL]
Working on a Flash iOS app and I need to utilize a couple Apple APIs. I was thinking, would it be possible to write Pixel Bender classes to access their API? If so, could someone provide a small example to get started? Or is there a different / better approach for this?
View 1 RepliesI write a Pixel Bender kernal for my flash.I know that the pbk would run in another thread.But when I run my swf, the GPU usage shows 0%.I want to know does the Pixel Bender with Flash would use the GPU.

I pass, as parameters, the center of the flashlight.Now, I want to have more than one flashlights (n value).I don't think so I can use Arrays in Pixel Bender, so I thought about ByteArrays but I don't know how to use it in Pixel Bender.
View 2 RepliesWe create Flash games which are embedded within third party wrapper SWF files, which are exported for FP9.
If I create an FP10 SWF which uses Pixel Bender classes (Shader, ShaderData), when I run them in an FP9 wrapper within an FP10 player, an error is thrown
VerifyError: Error #1014: Class flash.display::Shader could not be found.
Is there any way to get access to these FP10 classes - or does the version of the outermost wrapper determine what's available to child SWFs? Is this something to do with applicationDomain?
Simple question here, lets say you have a color in RGB, white:255, 255, 255Pixel bender needs values between 0-1 not 0-255.So white = 1, 1, 1What about:134, 132, 123I dont know how to work it out.
View 3 RepliesI want to know relationship between flash cs4 and Pixel Bender Toolkit 2. Now I use Pixel Bender Toolkit 2 to make some effect,and use File->Export Filter for flash player,then it will creat a .pbj file. I don't know how flash cs4 use .pbj file? I use google to search it,but I don't find answer. Anyone could give me detail example about flash cs4 use .pbj file?
View 1 RepliesI am building a Flash Application which will allow a user to mix two mp3 files and send the mixed result to our server.
Using Pixel Bender I am already able to create a mix:
public class Mixer
{
[Embed(source="mix.pbj", mimeType="application/octet-stream")]
protected var NewFilter:Class;
[Code].....
Not sure if the event.byteArray can be transformed to an mp3 file? Ideally we'd send the mp3 to our server for uploading.
Effect is generally in mostly vertical with slight horizontal offsets looks like: often used by paintors in sky painting like here

View 2 RepliesI am trying to create a custom blend mode much like the blur blend in Windows Vista, where all the of the contents in the windows behind the one on top are blurred. (I hope you understand what I mean.) I would like to accomplish this using a pixel bender effect, naturally. Unfortunately I can't get any kind of blurring (or for that matter, any image distortion at all) to work when I use a pbj file as a blend mode. These kinds of effects work fine as a filter, and seem to work fine in the toolkit as well, but don't seem to work at all in flash as a blend mode. it seems that flash doesn't allow you to sample any points except the current x and y that it is working on when used as a blend.[code]
View 3 RepliesI've being playing around with a pixel bender tutorial from hereI implement the filter like this
Code:

I am writing a pixel bender filter to be used in Flash. When I run the kernel in Pixel Bender I can see and change all my parameters (float and float2), but once exported to a .pbj and embedded in Flash I get a "TypeError: Error #1010: A term is undefined and has no properties.". I have run a loop tracing the shader data and it does not show that the parameters are there I change the version number for each export and I am surely embedding the latest version.

View 2 RepliesAccording to the pixel bender specs a shader can have one or more outputs. The pixel bender toolkit, whose "export to flash" option tends to be preety strict about the flash specific do's and dont's, would even compile such a shader without complaints.
However actionscript's shader related classes seem to be geared toward single output shaders. Is there any way to have multiple shader outputs in flash?
I haven't seen many Flash games on facebook or other applications really utilize it yet (or appear to utilize it).
Are there some good professional examples of its use?
Is pixel bender just too slow for practical use on today's web hardware? I read that Flash will fallback to interpreted mode on older Macs (PowerPC), for example, but is that a deal killer?
I've seen some example of using a Pixel Bender for mixing two tracks together (per shader passes). However, would it be technically possible to write a Pixel Bender kernel that could do this?

Here's a snippet of a pixel bender shader that I'm using in Flash:
parameter float2 srcSize
<
parameterType: "inputSize";
inputSizeName: "src";
>;
input image4 src;
The width and height of the source image are filled in correctly in the Pixel Bender Toolkit, but when I run this shader as a filter in Flash Player 10, the srcSize value is not automatically filled in.
I'm looking for some help converting as3 code to pixelbender code in an attempt to improve the performance of my application. This as3 code goes as follows. I scan through the Number values of a bytearray in chunks. Lets say this chunk lenght was 100 numbers I read 2 numbers (left and right) and try find the maximum values. The numbers in my bytearray are PCM data so there is millions of them and this code can often take a long time to execute, especially on a low spec machine.
The whole aim of this is to render a waveform as quickly as possible. I know very little about pixel bender. I can basically make a new file and create a shaderJob of it in flash but I'm really uncertain how to approach this...

I have a datagrid that gets its data from a webservice.When data from the webservice is retrived it calls the following function:
private function onListReg():void
{
arrRegOld = WSAutoreg.list.lastResult as ArrayCollection;
arrReg = WSAutoreg.list.lastResult as ArrayCollection;
[code].....
The intent is when I hit a update button, it compares arrRegOld with arrReg and see if any values have changes. The problem is whenever I change values on the Datagrid it changes on both the dataProvider and on both ArrayCollections.What should I do so that the binding applies only to one ArrayCollection?
I have a simple movie clip, (which is a simple drawn white shape) on my stage (instance name 'changed') and an input text field (var: 'hex') with a button (called 'set button'). I also have a list of values and their corresponding hex codes (there are 940 values in total). What I would like to achieve is, when a value (from the above list) is put into the input text field, and the 'set' button is clicked, the movie clip instance RGB values are set to the corresponding hex code (from the above list).

I am getting a mysterious result when trying to load profile images from a logged in Facebook user's friends list into an as3 canvas app. In pretty much every (non-facebook) application I've made where loading an image is required I use the following:
private function loadPic():void
{
var url:String = Facebook.getImageUrl(_friendslistObjectArray[_loadCount].id);
_picLoader = new Loader();[code]............
I can't retrieve the image from the event object,and I am given no error at all.It all just fails silently.If I remove the line var image = evt.target.content, the process runs through the whole array.I can't think of any reason this would occur. Furthermore, if I look in firebug's net activity, I see I see the images get loaded as long as I do not have the line I just mentioned included. I just can't seem to get the image data from the event object to add it to stage or a container movieclip.
[code]This script is for a loader image gallery in flash, as part of a class assignment. What happens is that in flash, when I open the swf file, the initial image (images/nair_evanescentautumn.png) will load fine. However, clicking on any thumbnail image (including the exact same images/nair_evanescentautumn.png), will result in an error saying the file cannot be found.I cannot figure out why it is doing this... I've tested it over. Clicking each thumbnail does go to the correct position in the two separate functions. All said full-size image links are in the folder images/, and replacing the initial loader image will load the other images in place of the default one. However, clicking on any thumbnail still results in URL not found, even though everything works correctly.[code]Before anyone asks why I'm putting this kind of content into a flash site, I'm not--this is only for a class assignment. I'm just trying to figure out why my images aren't loading right when I'm only doing the exact same thing in the functions as I am on the other pages.Of note, commissions.swf has the exact same feature, just with swf files loaded instead, and it works perfectly fine. home, traditional, digital, and photography all have the image gallery, and all have the same issue (I only referenced one page because if I can fix one page I should be able to fix all of them).As for the artworks, they are all my fiance's. The website design was built for her, and I used the website design for this project because I didn't want to have to build an entirely new interface design. Since the project also required a gallery, I felt that this interface would work just fine.

View 2 RepliesI am trying to set a constant hue value for entire image with using ColorMatrix. My goal is to make entire image look with same color without loosing brightness of any area. I found a way to shift the hue values of an image by using ColorMatrix but i couldn't find any way to set same hue value for all pixels. I can do it with iterating every pixel of image but this approach is too slow. I am not sure if it is possible to do it with ColorMatrix and i am open to possible solutions other than ColorMatrix approach.I can do this with iterating pixels but not with ColorMatrix.I am trying to do this on Android but i believe the question is not directly related to the android since ColorMatrix approach is common on other platforms like Flash, C# etc.
