Actionscript 3 :: Translating Hex Values From ByteArray?
Jun 17, 2011
I'm new to using ByteArray, and am trying to parse hex color values from an .ase (Adobe Swatch Exchange) using ByteArray in AS3. I can see position of the hex values using a hex editor, but don't know which methods to use to parse the hex value from there. Here are the values copied from the hex editor. The 2 color values are #ffffff and #cdcdcd:
I've made a weak initial attempt to get the first color, but am stuck here :
var byteA:ByteArray = _fr.data;
byteA.position=29;[code]....
how to parse out the color value, so it can be added to the temp array tA? As a bonus answer, since there can be multiple colors in a swatch, advice on a method to parse out all colors in a given .ase file
Is it possible to fill a ByteArray with random values that SoundMixer.computeSpectrum() could read? If so, how?The reason I ask is if a tab like youtube is open, I get a security error. I would at least like to see some random values even if they arent matched with the music playing.
i'm studying getPixel32() and the Bitmap and Bitmap Data classes.Basically, i'd like to know how to output a simple trace of an ARGB from a hexadecimal value.as an aside, i'm under the impression, which i assume/hope is wrong, that hexadecimal values can't produce as many colors as RGBA values.perhaps "web safe" has thrown me off with understanding the usefulness or desire to use colors produces with hexadecimal values.
I have flash set up to read an external .jsp file.the problem is that this jsp file contains names with chars such as "&" and "â„¢" among others. when flash loads this file it halts when it hits those chars. does anyone know how to fix this problem?
Newcomer to Objective C and trying to translate concepts and sytax I know from ecmascript based languages to Objective C.Is it proper to think of the .h header file in ObjectiveC as an Interface in Actionscript?Lets take the following code example in Objective C which calls a method containing 2 arguments
I am working on a game, made with Flash (using AS3) The game has a fast ball and when this ball hits an object it has to make a sound... but the sound starts with delay (so the ball is far away when the sound is played).This sound is edited by me and it hasn't got any silences at the beginning.The method i'm currently using is the simplest one:
public var sonidoPuntos1:sonidopunto1 = new sonidopunto1()
and then...
sonidoPuntos1.play()
I am trying to introduce the file into a ByteArray and then playing it from there...
I've gotten these sliders to work but can't get the output values to add up. For instance, depending on the values for slider 1, 2 and 3, I need the total to show up in a separate text box. I keep getting a NaN message in the text box.Here's the code I have so far:
I am trying to create a new swf with AIR and Flash CS3. All I want to do is push a button and have a new swf saved to the desktop with a line of actionscript in it. The actionscript can be anything stop(); - for instance.I have been messing around with ByteArray and I can save an image to a swf but I can't find any information on what I want to do.
at the current status of my project i must write an application (With AIR or ZINC) who its job is:
1st-getting some files from user. 2nd-modify them with an algorithm (encryption or encoding or changing byteArray) to simply corrupt the file and make it impossible for other applications to read the corrupted file!
Is there a way to write a UTF-16 string into a ByteArray in Flash/AS3? Basically I have a string (var test:String="allan"; for example) and I would like to write that into a ByteArray with UTF-16LE encoding. In this case it would be "61 00 6C 00 6C 00 61 00 6E 00".
I've tried using utf16le.writeMultiByte( clipText, "utf-16" ); but it just comes out with what appears to be UTF8 (or just straight ASCII given the test string).
The use case is to save a UTF-16LE file using FileReference.save(), which I understand I can do by passing it a ByteArray with the correct character encoding in it. Passing just a string saves as UTF-8. Hence the need to convert and store into a UTF-16LE representation in a ByteArray.
I am trying to serialize a Bitmap to store in an XML file. My plan is to turn the BitmapData into a byteArray, but I haven't been able to fine an example of this.
i'm using AMFPHP to stream content from my server to my Flex application, since Flash is a clientside technology i would like to make it harder for people to grab protected files, so i created a system that streams swf file to another flash player, i've done all the testing on URL stream, now i want to pass the swf file to the player as bytearray .. since i think it's safer and harder to break and in the future i even might do some encryption of my own if i became more familiar with bytes and bits .. anyways is my method the best one? (SWF to ByteArray?) or is there a better one? if the bytearray method is the best, i am facing a problem in outputing the swf file in the right format, i'm using a very primitive method .
We have requirement with the AIR application which loads the flex generated swf which inturn loads the flash generated swf using SWFLoader. This is not working as desired.This gives the following error: SecurityError: Error #3226: Cannot import a SWF file when LoaderContext.allowCodeImport is false.
The BLOB field (pic) is turning out as 0 Bytes when trying to send ByteArray through as3 to PHP, so i assume the PHP script or the HTTP_RAW_POST_DATA isn't working.I think the Flash part is working, I have set a trace() to see if the bitmapdata is coming through and it seems it is, so I'm assuming its my php side.3
private function export():void { var bmd:BitmapData = new BitmapData(600, 290);
I want to make a flash application in which i will load 3-4 different mp3 files of different instrumental music. After loading it I want play all files. Further I want to save or create a merged mp3, from all mp3s sound files in a single mp3 file.
Is it possible to convert different mp3 sound track in to different ByteArray and later using any other technology like PHP or C# can we merge all byteArray in a single byteArray to create a single mp3 file. So that we can listen all instrument playing in a single mp3 file.
I have a load of information in a swf that I'm loading at runtime. From that swf I need to get raw vector data out of some MovieClips, and other MovieClips I need to instantiate and put on the stage.Currently I can get at the vector data by loading the swf as a ByteArray using a URLLoader and parsing it with a bit of help from as3swf.
However, if I want to instantiate one of the MovieClips directly I would usually load it with a Loader and get at the MovieClip via loaderInfo.applicationDomain.My question is: can I either load the swf as a ByteArray with URLLoader and somehow instantiate MovieClips from that, or can I load the swf as a DisplayObject using a Loader, get the MovieClips and then convert the swf to a ByteArray before giving it to as3swf for parsing?
Summary: is there usually a lag when recording audio from the mic? I am using Thibault Imbert 'micrecorder' library on google code to record audio from the mic into a ByteArray. I am instructing my users to speak two seconds after the recorder starts. I know its two seconds after the recorder starts, rather than two seconds after the user presses the record button, because micrecorder issues time adjusted events of the recorder progress.
When I get the finished ByteArray the actual floats inside it that record the user speaking seem to be 2.5 seconds worth of samples into the ByteArray! So my question, as this is the first time I have recorded audio, is it usual to find a lag like this when recording? Or do you think I am getting something wrong with my math when indexing into the ByteArray?
I need to save email-id in my login form through the cookies. if I use shared object I am able to save but my requirement is need to save in cookies. How can I save? I got sample code from net. Attaching that code `package com {
import flash.external.ExternalInterface;
/** * The Cookie class provides a simple way to create or access * cookies in the embedding HTML document of the application.
I need to be able to compare the number of whole days between two dates in ActionScript, is this possible? I'd like to test if one date is 7 days or less after today, and if so is it one day or less (if it's before today this also counts).The workaround I have in place is using the .time part of the date field:
// Get the diffence between the current date and the due date var dateDiff:Date = new Date(); dateDiff.setTime (dueDate.time - currentDate.time);[code].....
As I say - this is only a workaround, I'd like a permanent solution to allow me to check the number of whole days between 2 dates. Is this possible?
I have a java server sending the time with:long time = System.currentTimeMillis();I put this in a packet. It takes up the first 8 bytes of the packet and send it to the as3 client.Then in as3 I read the packet but since there is no readLong function with ByteArray, I can only think of reading it with readDouble to read the first 8 bytes of the packet. I'm not sure if this is the right way to do it.
I compared it with the time from AS3's function: Date().time;The time I get from AS3's Date().time is different than the time I receive from reading the packet with the time sent from the java server.I'm not sure if I'm using the wrong time functions or reading the packet wrong.
I want to convert a ByteArray wich contains a .flv file read through a socket connection to a video playable object and play it, or attach it somehow to the netstrem as its source. Why this ? I'm trying to write an app using AS 3.0 that connects two swf clients to each other directly without a server (after they know of each other) and allow them to exchange video sequences. So the reverse way video -> bytearray -> network -> reciever ->video would be of interest aswell.
My Flash movie has connected to a server via Socket. The server has sent some data over the Socket connection. This data consists of a 4-byte message header which describes the length of the incoming message and then the message itself. In this particular case, my message has a length of 500040 bytes.
My code receives the first installment of this long socket message in a block of 4,380 bytes. I know this because of trace statements in my socketDataHandler function. It peels off the 4 bytes at the beginning and interprets them to get the incoming message length of 500040. The remaining 4376 bytes go into a ByteArray var (a property of my class) called buffer. As more blocks of data arrive, the socketDataHandler function is repeatedly triggered and the extra blocks are concatenated into the buffer.
I've extended the ByteArray class, like this:[RemoteClass(alias="MyByteArray")]public class MyByteArray extends ByteArray {}and cloned an instance of this class using ByteArray#readObject()/writeObject(). However, for some reason, the cloned object is an instance of ByteArray rather than MyByteArray. This
is illustrated in the following example: registerClassAlias("MyByteArray", MyByteArray);var b1:MyByteArray = new MyByteArray();var tmp:ByteArray = new ByteArray();tmp.writeObject(b1); tmp.position =
I have an application with microphone record and i mix another sound from song. For this step is ok i can save to my desktop and the mix is good.But i would like to play my mix from bytearray.The sound is very slow....... and not same that my file save,My code:
var epos:Number=0 //ByteArray in which the microphone sound data is stored var soundBytes:ByteArray = new ByteArray();[code].......
I'm working on a local application ( it's not a website or nothing related ) and I have various FLVs with a very simple encryptation method (just like adding 10 at each byte). I can load/play them using NetStream.appendBytes() after my decrypt, but that happens only after I read all video data. What I really need is to stream those videos from a remote url, and decrypting while receiving data, using a OSMF player that I already have.
This is my current code just to play my decoded FLV byte array
private function playBytes(bytes:ByteArray):void { // detecting it's header if (bytes.readUTFBytes(3) != "FLV")
