Flex :: EOF Error Encountered While Converting Bytearray To Bitmapdata
Mar 18, 2010
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'm having a task in which I have to read and save images in the database.I'm using C#.net Webservice and SQlserver2008 database and I'm saving image as varbinary format.How I can read images from local system and convert it into byte array in Flex ?How to show images in Flex that are recieved in type Bytearray?
I am working on a flex project, where I have to load a couple of SVG files and compare their pixels. To compare the pixels, I like to convert them into a byte array (BitMapData). I am able to create a bitmap data for a PNG image, but not for a SVG image.
I'm trying to convert a Sprite that I have into BitmapData so I can perform some collision detection. There are a few things about the way the Sprites are used that is making this more difficult than I expected:
The Sprite itself is a container which holds another Sprite that actually has a box drawn in it. The inner Sprite is positioned negative half its width & height so that it can be rotated from the center via the container. The container may be rotated at any angle at any given time
So my approach thus far has been attempting to draw the outer Sprite onto a new BitmapData object with a Matrix to account for the difference. Whilst I can use a Matrix to make this work for one particular rotation angle, I cannot find a way to make it work for any rotation.
Here's what I'm doing to draw onto the new BitmapData:
var p:Product = getProduct(); // Product is the container with the inner sprite var bounds:Rectangle = p.getBounds(stage); var bd:BitmapData = new BitmapData(bounds.width, bounds.height, true, 0x00FFFFFF);
[Code]....
Translating by the same amount as the previous example will no longer work here, and the box will still be cut off. I've looked around at some solutions posted before or suggestions from other people but they don't seem to work for me due to my container Sprite and rotation.
I created an equalizer that works great, except every once in a while It throws the Error #2030:End of file was encountered error. Here is the code for the equalizerwhat is causing this?
var ba:ByteArray = new ByteArray();var frameHalf:Number = 0;var framePlay:Number = 2;addEventListener(Event.ENTER_FRAME, loop);function loop(e:Event):void{ if(frameHalf == framePlay) frameHalf = 0;
I have to convert a MovieClip to ByteArray and send it to php using the POST method. The person handling php says that only ByteArray needs to be send and conversion to JPG and PNG can be done from PHP side. When I built the option for saving on the local machine the following steps were used.
Converting to Bitmapdata Using JPGEncoder and PNGEncoder on the Bitmapdata Then assiging to byte array variable.
So in this case different byte arrays were used for saving in case of JPG and PNG and it worked.
I found the code to convert movieclip to bytearray in Stackoverflow itself
I was testing out some applications written in AS3 and it worked fine untill I encountered one app when I got the Flash10i.ocx error message. I uninstalled and re-installed the flash player and this time when I run the application I got the Flash10k.ocx error. I am using IE 7 and Flash CS5 and my OS is Win XP professional. I am trying to go through the code to see if there is any issue. Meantime I am posting the code here, if anyone is able to spot any issue with the coding do share with me. The code is from the book 'Learning Flash Media Server 3':
myasfile.as holds my code, and starts with "@estr = function ()" When I go to export movie, I get "myasfile.as, Line 1 unexpected '@' encountered" Why do I get this message?
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 trying to read out some BitMapData into some kind of readable output.
Reason for this is I'd like to trace out the ByteArray and hopefully cut and paste its details into an .as file and then compare it against another BitMapData Object or byteArray that is generated within the app.
Basically I want to compare differences between the two and report back how many pixels or something are different.
It might seem like a strange or approach.
I can create a BitMapData Object, it traces back as [object BitMapData] - so I thought awesome just loop through the Object... But looping through the Object traces nothing at all back out.
So I tried to create a ByteArray and then convert that to a string, but all I get is wierd 'y' chars with two dots on the top of the char.
I've left some code below,
Code: public function GetAndCompareBitmapData(target:DisplayObject) { var bd:BitmapData=new BitmapData(target.width,target.height); trace("bitmapData "+ bd); // trace [object BitMapData]
i 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 ?
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?
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.
I'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 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?
When I publish the file, I'm getting the following error message in the Output panel:
**Error** Scene=Scene 1, layer=Layer 2, frame=1:Line 7: The class or interface 'BitmapData.loadBitmap' could not be loaded. var plaid:BitmapData.loadBitmap("plaid");
I am trying to use the reflect class from "http://pixelfumes.blogspot.com/2007/03/reflection-class-v3-with-source .html" but I keep getting this error:
ArgumentError: Error #2015: Invalid BitmapData. at flash.display::BitmapData() at Reflect() at Site_fla::GalleryPage_29/loadThumbs() at Site_fla::GalleryPage_29/sortXML()
[Code]...
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'm not sure about the purpose of the throw statement.What exactly does it do in the following example?Does it throw the error message on the screen?The manual is silent about what the throw statement does upon execution.The throw statement
Flash Player and Adobe AIR throw exceptions when they encounter errors in your application at run time.In addition,you can explicitly throw exceptions yourself using the throw statement.When explicitly throwing errors, Adobe recommends that you throw instances of the Error class or its subclasses.The following code demonstrates a throw statement that throws an instance of the Error class, MyErr,and eventually calls a function,myFunction(), to respond after the error is thrown:
var MyError:Error = new Error("Encountered an error with the numUsers value", 99); var numUsers:uint = 0; try { if (numUsers == 0)[code]......
Notice that the catch statements are ordered so that the most specific data types are listed first.If the catch statement for the Number data type was listed first, neither the catch statement for the uint data type nor the catch statement for the int data type would ever get executed.
Is there any way to take a "screen capture" of a movie while it is running, and store it as bitmap data? For example, if I wanted to store off "thumbnails" at arbitrary times through out a session, is there any way to do that other than some horiffic hack to save the state and position of every movieclip on stage?
I'm moving a Flex 3 site to Flex 4, but when I run the application, it attempts to download a .swz file from Adobe, and gives the following error:
*** Security Sandbox Violation *** Connection to http://fpdownload.adobe.com/pub/swz/tlf/1.1.0.604/textLayout_1.1.0.604.swz halted - not permitted from http://localhost/Fl/CityGIS/main.swf Error #2048: Security sandbox violation: http://localhost/Fl/CityGIS/main.swf cannot load data from
[code]....
Following this is an attempt to download the same file from localhost.Is there a way to configure the SDK to get these files, or an issue with the configuration of my application?
Code: ArgumentError: Error #2005: Parameter 0 is of the incorrect type. Should be type BitmapData. at flash.display::BitmapData/hitTest()
This is the line where I get this error:
Code: if (player.bitmapData.hitTest(player.point, 255, tempUpgrade.bitmapData, tempUpgrade.point, 255))
I have absolutely no idea what went wrong. My object (tempUpgrade) is generated inside of a manager-class. There I can define the look of it and it gets cached. The image I use is a spritesheet (png) that's embed inside of my library-class. The spritesheet is splitted into appropriate pics via a CacheTileSheet-class.After that process they get thrown inside of an array because I need the bitmapData for pixel-perfect collision detection. Of course this is not the complete code so if someone needs more please let me know.
I'm currently writing a client in ActionScript 3 that talks to a Red5 application/media server via a NetConnection object. The server sends the client multiple types of data over this connection including video, audio and remote procedure calls. After an indeterminate amount of time (sometimes 10 seconds, sometimes 10 minutes) I see the following error in a popup window from my Debug version of the Flash client:"Error: Error #2030: End of file was encountered."
I'm in the process of trying to figure out what's causing this error and the thing that's really driving me nuts is that I can't seem to catch it. I realize that the error probably indicates some low-level network read failing, but the fact that it generates a popup window in the debug flash player implies that I should be able to catch it.Since the error has no associated stack trace, I went so far as to add the an uncaught exception handler on my base Sprite object:
public class MyClient extends Sprite { public function FOWClient()[code].....
My uncaught exception handler will get called properly if I purposely throw in some errors, but it never gets called when this Error #2030 happens.How the heck can I catch this "End of file was encountered" error and deal with it in code? If I can't catch it, are there any thoughts on what's causing it and how I fix that? I've narrowed it down to having to do with RPC calls being made from my server to my client because when I disable those, but leave audio & video, I don't see the issue. Unfortunately, I don't yet have any good ideas beyond that.
I have a password text box set up and for the submit button I have this script and it keeps giving me errors.. Basically I want to say if the password = one then go to this url ... if password is = two then go to this URL if it is none of them go to the next frame.
I am having an issue with using BitmapData.draw(stage). I am getting the following error:
SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: file:///C|/Documents%20and%20Settings/bla...bla...bla.swf cannot access null. No policy files granted access. Here is a portion of my code:
var bd:BitmapData = new BitmapData(2800, 2100); bd.draw(stage);//this is where the error happens All of the files referenced (.xml/.jpg/.swf) are located in the same local folder as the main .swf. How do I get around this error? The main objective is to print the stage using PrintJob(). I am using Flash Professional CS5.5 and publishing to Flash 10.0/10.1. Let me know if I need to supply any more info.
I'm currently working on a flash game and I need to know how to addChild a BitmapData or draw a BitmapData to screen. If I can't than how can I give a DisplayObject my BitmapData?
addEventListener(Event.ENTER_FRAME, Pixel_Perfect); function Pixel_Perfect(e:Event):void {[code]....
Enemy1 is a class is that makes a difference
I didn't write this code as i am not this advanced yet but really needed this script, this script normally works but now i am recieving errors
Error: ArgumentError: Error #2015: Invalid BitmapData. at flash.display::BitmapData/ctor() at flash.display::BitmapData() at IceMountain_fla::MainTimeline/Pixel_Perfect()
