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?
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?
I 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.
What is the best way to turn turn off (using PixelBender) colors that fall within a certain range. For example, turn off all colors between 0x0000FF and 0x00FFFF. This has to work in Flash.
View 2 RepliesI 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.

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 doing a flashlight in pixel bender and works great. 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 RepliesSimple 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 1 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]

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'm working on a web banner campaign, which as you probably know involves strict file size limits -- an extra 1 or 2k here or there can mean the difference between an ad being accepted or rejected by publishers. What I've been finding is that that files published from Flash CS4 are about 10% bigger than the exact same documents published via Flash CS3. Is this a documented bug with Flash CS4? Is it just not ready for primetime, as far as producing banners goes? I'm using AS 2.0, targeting Flash Player 8; I've deselected the option to include XMP metadata, and checked the Compress Movie checkbox. Using the new (slightly awkward) Motion Tweens or using the old-style Classic Tweens doesn't seem to make a difference.
One interesting tidbit: I'm using TweenLite and one easing class, which should add around 5k to my file. However, in CS4, the size report says that I've got 17k of ActionScript classes included. What's weird about that is that if I comment out the import statements, size report now says I have 5k of ActionScript 2.0 classes - but my file size doesn't drop by a corresponding amount (it only decreases by about 5k). Very odd.
I am trying to use POST in Flash (ActionScript 2), to POST values to PHP mail script.I tried the PHP mail script with HTML form, and it worked perfectly fine.But when I POST from flash and input non-English characters, I get "????" in the mail.I tried utf8_encode($_POST["name"])Edit:I also tried utf8_decode($_POST["name"]), it didn't work.Update: (So you wont have to go through all the comments)I checked the variables in Flash,the values are stored correctly.The HTML page where the Flash is embedded is UTF-8 encoded.I watched the POST headers with FireBug, the POST itself is already messed up, showing "????" instead of the real value.The the messed up "????" value, is currently url-encoded by flash, and decoded by PHP, resulting in $_POST["name"] == "???";I suspect its the sendAndLoad method that creates the mess.Update:Here is the flash code:
System.useCodepage = true;
send_btn.onRelease = function() {
my_vars = new LoadVars();

I have one that's almost done and the stage size is 700x800 px. But I'm starting to worry if that's going to look too small? To change it, will be a lot of work - there's animation, imported Jpegs etc. As far as I can tell, in order for it to look correct in larger dimensions I will need to basically create it again from the ground up. So, I'd really like to get an idea of what the optimal pixel dimensions would be for ecards to run on multiple platforms.
I really want to do this and I don't feel like I can move ahead until I get the viewing size correct. I don't even mind redoing the card. I just want my future cards to be the correct size. I don't want to have to come back and redo them all. By the way, the cards are being made in Flash. The site itself will be created in DreamWeaver.
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()
