Actionscript 3 :: Filter A Specific Color From A BitmapData Object (or Byte-array)?

Jun 22, 2010

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 failed me...). Here's my current logic, which I want to improve:

Actionscript 3 :: Reading A Byte Array Into An Object After Being Decoded From A String?

Jul 29, 2011

I'm trying to serialize and deserialize a byte array to a string using Base64 for as3.

Here is my code

public function Serialize(vector:Vector.<Action>):String
{
var bytes:ByteArray = new ByteArray();
var serialized:String = "";

[Code].....

is the error I get after calling deserializedObj = deserialized.readObject(); Should I be get that error if I'm just trying to put this into an object? I'm not trying to put it into an action class object yet, but if it is then the action it's getting doesn't have parameters that were originally inside.

Audio :: Extract Sound Object To A Mono Byte Array In AS3?

Jan 18, 2012

I'm trying to prepend the byte array of a sound object to a captured microphone sound byte array.

It works, but the extracted sound object get pichted down and doubled in length. I guess this is because the byte array of the sound object is in stereo, while the mic byte array is in mono.

I have this:

sound.extract(myByteArray, extract);

myByteArray now contains the stereo data. How can I turn this to mono

UPDATE:

Here's a working solution:

existingByte.position = 0;
var mono : ByteArray = new ByteArray();
while(existingByte.bytesAvailable) {

Flash :: Use Of The Array.filter() Method For Searching And Retrieving An Object Instance From An Array?

I am curious if this is an okay implementation of the Array.filter() method.

I was not able to figure out an implementation of the callback function for the filter() method, where the callback was outside of the getGallery() function. I wonder if there is a way to get the isGallery function outside of the getGallery scope?

IDE :: Filter Is Using Too Much Memory - Apply The Filter To Only A Specific Area Of A Movieclip?

Jul 15, 2009

To achieve a zoom effect in our 2D flash game, we make the background of the game much bigger than the visible stage. This becomes a problem when the background is complex or when we apply a grayscale filter to the background. Is there a better way to do zoom? Or, is there a way to apply the filter to only a specific area of a movieclip?

ActionScript 3.0 :: Excluding A Specific Value From An Array And Changing The Background Color

Flex :: Applying Blur Filter To BitmapData

May 14, 2011

I am using to blur an image using BitmapData. The function is called on a Slider_changeHandler(event:Event):voidevent and the value of the slider is passed to the function as blurvalue.The problem is the function works but seems to be cummalative (if that's the correct word!), that is, suppose I slide it to the maximum and after that try to reduce the blur by sliding it back towards the front the blur still keeps increasing. How do I make it to work so when I will slide it up blur increases and when I slide it back blur decreases and when slider is at 0, no blur is applied.[code]

Actionscript 3 :: Two BitmapData Objects - Apply A Colorburn Or Darken Or Multiplay Filter

Dec 27, 2011

Photoshop and Fireworks both have some nice filters. When you put one bitmap over the other, the first bitmap can act as filter. For example, the white pixels of the top bitmap lighten the pixels of the bottom bitmap. Is there any way to apply this in as3? What I am trying to accomplish: I have a large single-color bitmapdata object. I want to overlay perlin noise and lighten/darken the single-color bitmap to give it some random/natural look.

Actionscript 3 :: Php - Php Mp3 Byte Array Transport And Write

Feb 2, 2012

I'm working on a childrens game (flash as3) in which stories, poems, songs, etc are read to the child. There's a voice recording reading/singing the text, the text highlights as the words are spoken/sung. The child may toggle on and off the voice and word highlighting independantly. The child may also opt to make their own recording. Now said recording works fine. I'm able to capture it from the mic and the child may play it back no problem. The issue lies in that the client wants the child to be able to save this recording to a web server.

I thought I had the issue solved by using a URLRequest and URLLoader object. The mp3 was showing up in the specified folder on the webserver. I played it with a media player and it worked. The child could also load said file no problem. THEN, when I tried it via browser(instead of flash player) I got the dreaded sandbox error. The only way such an operation with said objects can occur in a browser environment is if it's user initiated via a dialogue window. This is children were talking about and we're not saving locally anyway.

The child is provided 3 save slots which they click on (WSprites). Which technically is user initiated, but flash has no way of knowing that. The 3 save slots hold the sounds in memory and only change when the user records or loads. When the user saves, they get sent off to php to save. Now I did try using js as a middleman, but I ended up losing my bytes in the process and my js and php are probly the weakest areas of all my programming skills.

ActionScript :: Passing An JPG Byte Array To Javascript And Eventually To PHP

May 18, 2010

Our web application has a feature which uses Flash (AS3) to take photos using the user's web cam, then passes the resulting byte array to PHP where it is reconstructed and saved on the server. However, we need to be able to take this web application offline, and we have chosen Gears to do so. The user takes the app offline, performs his tasks, then when he's reconnected to the server, we "sync" the data back with our central database.

We don't have PHP to interact with Flash anymore, but we still need to allow users to take and save photos. We don't know how to save a JPG that Flash creates in a local database. Our hope was that we could save the byte array, a serialized string, or somehow actually persist the object itself, then pass it back to either PHP or Flash (and then PHP) to recreate the JPG. We have tried:

Php :: Uploading Image To Server Using Byte Array To Upload In Flex 4.5 Air?

Jun 13, 2011

I'm using Flex 4.5 in a Mobile air for android application. So, Using the Camera/Camera roll [URL]I want to do a simple upload using amfphp Note: Since this is how you get pictures on devices, i cant use the filreference because it wants you to get the pictures using "browse" which cant be done on android or ios My plan is, after I select a picture or capture one with the camera, in the event I can get the local url to the picture that was taken like this:

[URL]

I'm putting this in the imageURL var (i'm assuming i should make it into a byte array to transfer it, im not exactly sure this is my first time making something like this)Here's how i'm taking that image, making it into a byte array, and using amfphp to send the upload to the server:

protected function upload_btn_clickHandler(event:MouseEvent):void
{
var request:URLRequest = new URLRequest(imageURL);
var urlLoader:URLLoader = new URLLoader(request);

[code]....

But i'm getting an error NetConnection.Call.BadVersion.This is the first time im trying something like this so im not even really sure if im going about it right. All the examples I find online go about using the fileReference class, but that seems to require me to use the "browse" method, and im on a mobile application that uses the camera and camera roll to grab pictures off the device, and im not sure how to incorporate that into the fileref class. I figured i could just get the byte array and send it to php myself and it should be just fine.
