I need a function to change an ByteArray to BitmapData in 1 function:
makeBitmapData(bytes:ByteArray):BitmapData
Is this possible? Cause all I can find about this is first put the bytes in a loader. add listener to the complete event and then call a function that make the bitmap/bitmapdata. can this also be done in 1 function?
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.
View 1 Repliesi want to do some cryptographic routines in my flash. I've encrypted .jpg files on my server, so I can't use simple Loader class, to download that data as Bitmap. I'm thinking to:
1) download it with URLLoader as BINARY data in ByteArray class.
2) decrypt the data
3) convert to BitmapData. (..., is this possible ?
how could I do image crypting in fl.
is there anything that will take a very large png (even larger then the total pixel limit of BitmapData) and load in the png as raw bytes into a bytearray and then take that array and grab only portions of the image to be able to generate a grid of usable bitmaps to render the very large png..I got to the point where I was able to get the png as a bytearray but from there I don't know how to grab a portion of the bytearray and attempt to load the partial bytes in a loader via loadBytes()..basically I think I need a decoder to decode the partial bytes to a bitmapdata.
View 2 RepliesI'm trying to grab the BitMapData from an Image, convert it to JPG, and send it to a server where it will be written to a file. It "looks" like it works, the resulting .jpg is the right size and displays in an image viewer, but there is no picture... just an off-white background. Here's a code snippet:
imgTemp.addEventListener(FlexEvent.UPDATE_COMPLETE , imageLoadedHandler);
...
private function imageLoadedHandler(event:Event):void {
if (imgTemp.width == 0) return;
[Code].....
Then send "ba" to the server where it's written as a .jpg.
The data "looks" right when I receive it on the server, correct length, bits look the same.
I am using [code]...
In the 4th line in the code above i am getting "Error: Error #2030: End of file was encountered." I checked the length of the pixels object which is 4 times the width*height of the rect object. Given that setPixels() functions reads unsigned int from bytearray and sets that value to pixels, I think it should work.
But I have no clue why this wont work. The pixels object is filled after RLE decoding of the data which i get from a server.
Is there any work around or any other method which I could try to use. The loader class wont work as the data that I get from the server is not in any of the recognized format.
i am rendering a BitmapData from my webcam and sending the rendered ByteArray(i cant compress using ZLIB because its not running on AIR) file as binary to a server side. problem is each JPEG picture is around 40kb and it needs to be compressed a bit.now i am not talking about resizing the image, just making the file size smaller. anyone know how to do this?

I am using Flex's Alchemy library to generate SWC's out of C files. I have a byte array (unsigned char buffer[size]) in the c-layer that I'd like to return to the ActionScript layer as a ByteArray. Do I have to iterate through the array and explicitly call AS3_Set on each element or is there a way to just return the entire C array at once?

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 can't seem to call my bitmapData from another function, if the bitmapdata was made in a function in the first place.If you chuck it into flash, it'll run the function dd() and it'll make a bitmapdata, however, if you try to trace it or call to it.You can't you get "undefined" back..But if i were to take it out of a function and put the bitmapdata on the frame without a function enclosing it, it works fine.[code]Anyway know how I could call my bitmapdata when it's generated by a function?

btw, first I used assigned thumbContainer as the mc argument (outside the loadThumbs() function) and it worked but not exactly what I wanted... because I thought it is supposed to update when the movieclip is animated but it actually didn't... when I use a scroller, only the thumbs that are first loaded to the stage get the reflection..
I've been using BitmapData.copyPixels() to draw graphics onto a canvas (Bitmap).I need to rotate the resulting graphics without the use of draw() because it's vastly slower.How can I rotate the target graphic? I'm assuming that there might be a formula or library that I can use which will first reorganize the pixels that make up a graphic based on an origin (point) and radians.I'm pretty certain that I'm not capable of creating such logic, so if there are any known libraries that do this, that would be awesome.I'd like to achieve something similar to XNA's SpriteBatch.Draw() method, which accepts rotation as its 5th argument.

I am trying to do tiling with sprites. I want my tiles to be interactive, so that is why I am using the sprite object instead of using regular bitMaps to represent my tiles. You might be wondering why I wouldnt just use graphics.beginBitmapFill(tImage); and graphics.drawRect(0, 0,tWidth ,tHeight ); to pick out the tiles I want to use. Well reason being is because it turns out that drawRect() first and second parameters actually alter the location of where the actual sprite sits at.
So if I set the x and y properties of the sprite to x = 20, and y = 20. then I set my drawRect(20,20). it actually adds an extra 20 pixels to my x and y coords of my sprite. And I know the reason why, I just need to know a better way.

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 get Index out of bounds when trying to readObject on my Byte array into the XML object.

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 .
