I have an actionscript 2 code that uses base64 to encode/decode incoming data. problem is that data is binary and includes null (0 characters), actionscript 2 fails when handing null to charCodeAt.I figured what I need is an actionscript 2 lib that can do base64 encoding/decoding on an array rather than a String.

So, as the title says I was wondering if it is possible to scale bytearray/binary data from lets say 640x480 which is being captured from the stage to 1024 x 768

I would need to save some binary data (bitmap data or similar) as a part of XML file.[code]...
I suppose I must serialize or encode "ba" (binary bytearray data) some way to string before writeing to XML and decode them back during the reading from XML, but I cannot find the correct way how to do it.

i have a string which contains all binary data. the binary data represents a custom object in my application.
i want to convert all the data inside the string into binary format and store it in a ByteArray. then I want to read the object from the ByteArray using readObject.

I have some binary data and I can't store it in a string, as such I'm using a ByteArray. The problem is that I need some functionality that comes with strings, to be specific I need the charAt, substr, indexOf and substring methods.

I have some objects that are very, very likely to be equal. I'm comparing them every second to check if they're the same as one stored in a data model on the client.Instead of having to check 5-6 data points to make sure they're equal, I would like to compare the binary to tell if they're not equal, so I can quickly overwrite the object in the collection if they do not have an identical binary representation.for example, I have the following objects:
ActionScript Code:
class tag{
var xCoord;
[code]....
So, instead of doing this sort of comparison for every member in the class
ActionScript Code:
if ( tagOne.xCoord != tagTwo.xCoord ){
swapTagsInCollection (tagOne, tagTwo);
}
I would like to do something like this.
ActionScript Code:
if ( tagOneBinary != tagTwoBinary ){
swapTagsInCollection (tagOne, tagTwo);
}

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.

My program saves text files, which contain various text, some of which is a string representation of a ByteArray. It does this by using the toString() method of the flash.utils.ByteArray class, which I assume converts a ByteArray (for example, 13x$) into its string representation "13x$". So how do you reverse the process, and turn the string ("13x$") into a ByteArray (13x$)? Even if it's not that simple, I just need to have the ByteArray, put something in a text file, and extract from it the same ByteArray.

I'm recording audio in a Flash app and need to encode the bytearray being sent to the server. I haven't found a good encoder (client-side) to compress the bytearray before sending.

I have an array of objects. Each object has 3 integer fields and 2 binary fields.I've utf encoded the binary data and json encoded the array & sent it to Flex client side.On the client side, decoding data, I've got a String representing the binary data (utf decoded).Now, how can I convert this String to ByteArray? Or how can I read each byte of the String?

I've been asked to implement and MD5 hasher ActionScript-3 and as I was in the middle of debugging how I formatted my input I came across a problem. When I try and output the ByteArray as a binary string using .toString(2), the toString(2) method will perform some short cuts that alter how the binary should look.
For Example
var bytes:ByteArray = new ByteArray();
bytes.endian = Endian.LITTLE_ENDIAN;
bytes.writeUTFBytes("a");
bytes.writeByte(0x0);
var t1:String = bytes[0].toString(2); // is 1100001 when it should be 01100001
var t2:String = bytes[1].toString(2); // is 0 when it should be 00000000
so I guess my question is, might there a way to output a binary String from a ByteArray that will always shows each byte as a 8 bit block?

I m trying to write AS3 to take a screenshot of a MC thats on the stage and pass the data to a .cfc method which saves it as a jpg on the server.The current code I have kind of works except the jpg is unreadable.I think it has something to do with not using Flex, AMF, and writing binary files.When I look at the jpg via a hex viewer I think it doesnt have the right jpg header.The jpg begins with:c3 bf c3 98 c3 bf c3 a0 00 10 4a 46. When I think it should begin with:ff d8 ff e0 00 10 4a 46

I'm trying to get the sum of two number values in an XML file, so I'm doing this:
PHP Code:
_root.gallery_height = myGalleryXML.firstChild.attributes.height; // '200'
_root.spacing = myGalleryXML.firstChild.attributes.vertical_spacing; // '20'
_root.bar_y= _root.gallery_height+_root.spacing;
trace(_root.bar_y); //outputs 20020
The answer is supposed to be 220, but it comes out at as 20020 because the interpreter treats then as strings.
I can fix the problem by casting the type using the Number() method this way:
PHP Code:
_root.gallery_height = myGalleryXML.firstChild.attributes.height; // '200'
_root.spacing = myGalleryXML.firstChild.attributes.vertical_spacing; // '20'
_root.bar_y= Number(_root.gallery_height)+Number(_root.spacing);
trace(_root.bar_y); //outputs 220
This works fine, but is it *the right* way of doing it? Why is Flash treating my numbers as strings?

I have on my website a formular which sends its data to my database via a pho script.
everything works fine except for words like "� � � � ...." french and german letters like � �....etc
I tried to encode the data with rawurlencode or utf8_encode but still the same prob, the database can't read the letters �,�,�...etc is it possible to encode the data within AS? it seems to me the only solution....or not? something else, I ha ve a php script which takes from my DB data containing letters like �,�...etc...and before sending it to AS I encode it with utf8_encode and this wokrs really fine.

I get a raw data from Microphone's SampleDataEvent, and I want to encode this data before streaming to my server. So I'd like to know if there any standard audio encoder provided in actionscript3? Or do I have to implement it myself? I know that the Microphone class provide 2 codec (Nellymoser and Speex) that can be used when sending a stream to Flash Media Server( via NetStream) only. Is there any way we use this codec to encode raw data?
