Flex :: Why Pixel Bender Filter Behaves Differently In Toolkit Than In Air Application
Dec 8, 2011
I've tried this simpler filter with same Air code as below:
<languageVersion : 1.0;>
kernel NewFilter
< namespace : "Your Namespace";
vendor : "Your Vendor";
[code]....
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]

How 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

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]

I have an SWF file that works great when I publish it or view it in the Flash Player. However, when I use Simulate Download, all the buttons' functionality gets messed up - for some reason, clicking them results in the playhead going to other frames than it's supposed to. I've tried uploading the file to my website and the buttons don't work well there either.

I am using basic addEventListeners and functions to create a basic navigation for my homepage... when I test the movie on my local drive it fuctions perfectly, but when I upload it to the www, the movie behaves different... All the buttons must be clicked twice to function properly.... each button uses the UI Loader to load the appropriate .swf clip, but on the first load the movies dont function properly, when the same button is clicked again and the movie is loaded again, it works fine. I noticed cause I have a preloader for every movie clip that loads and on the first click it doesnt work, on second click it works, and because it function fine on my local drive I'm lost as to what I can do to fix the problem, or what the problem is.

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?

We 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.

I 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.

I 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]

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.

According 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 am looking for a fairly simple image comparison method in AS3. I have taken an image from a web cam (with no subject) passed it in to bitmap data, then a second image is taken (this time with a subject) to compare this data, from these two images I would like to create a mask from the pixels that match on both bitmaps. I have been scratching my head for a while, and I am not really making any progress. Could any one point me in the right direction for pixel comparison method, something like getPixel32()

Trying to create a profanity filter for an AS2 application. Working with code found on this site on another post that doesn't seem to work. Anyone see the issue here?
test.onPress=function (){
badWords = ["this", "wont", "work"];
var lc_content = formContent.toLowerCase();
for (j=0; j<badWords.length; j++){
[Code].....
The form field is called "formContent". This returns both traces no matter the input so it must be a problem with the structure but I can't see it.

Does anyone of You know how to effectively use the blur filter without crashing the whole application? Adobe admitted that the problem persists and there is no fix to it in CS3 in Windows XP/Vista.
