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?
View 2 RepliesI'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]
[Code].....
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.
As you can see when the bird flies across the screen it leaves part of it at the end, then clouds and the wolf do the same thing.This is all vector based artwork. It doesn't make sense becuase the simple images or complex images both leave a portion behind when rendering.The video plays perfectly in Flash. I tried importing it into iMovie and the same problem occurs.I don't even know what this is called so I can't seem to find any support on the issue
View 6 RepliesI 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

now how can i add byte variable to the canvas ? for example
var canvas:Canvas = new Canvas();
canvas.addChild(byte);
is it possible to add ByteArray to the canvas?
I am trying to display a bytearray as a resized image. The Image is displaying correctly, but the sizing is off. Let me explain.
First I have the image data encoded so I need to decode the image data
// Instantiate decoder
var decoder:Base64Decoder = new Base64Decoder();
// Decode image data
[Code]....
This works. The image is displayed correctly. However, if I hardcode the image (img) height the resized image is shown correctly, but within a box with the original image's dimensions.
For example, if the original image has a height of 300px and a width of 200px and the img.height property is set to 75; the resized image with height of 75 is shown correctly. But the resized image is shown in the upper left corner of the img container that is still set to a height of 300px and a width of 200px. Why does it do that? And what is the fix?
The best way to illustrate the problem is by placing the image inside a VBox and show the borders of the VBox. From the code block above, if I change the image height and set the image to maintain aspect ratio (which by default is set to true but I add it here for completeness). the problem becomes clear.
// Display image
var img:Image = new Image();
img.height = 75; // Hardcode image height (thumbnail)
img.maintainAspectRatio = true;

How to send a jpg image as ByteArray from as3 to javescript? And how to convert ByteArray to image in javascript?
View 3 RepliesI have an object that stores the compressed ByteArray version of an image (jpg or png). I want to keep it that way as the bytearray is about 30x smaller than the Bitmap it creates. The problem I run into is when I want to bind an image to this byte array. I can't really bind it to bytearray, because it requires a BitmapAsset as a source. Is there a way I can load a BitmapAsset from a bytearray but still bind to the bytearray when a new image is available?
View 1 RepliesI have a var that holds the String value for the path to an image. How can I use that to get the ByteArray from that image synchronously?
View 1 RepliesI would like to be able to move images into and out of Flex by converting back and forth between ByteArrays. I've been having some trouble with this, so I designed a simple test program, and even that I can't get to work. Here's the code I'm trying right now:

So far the process follows top to bottom: Click button 3, image displays, everything is going well. Click button 4, and I get "Error #2044: Unhandled IOErrorEvent:. text=Error #2124: Loaded file is an unknown type." after the line "loader.loadBytes(myByeArray);" in the function button4_clickHandler. As far as I can tell I'm using everything as intended.
I am trying to take images I am placing in a flex canvas component to a bitmap. I was able to get to the point where I'm not getting an error but then no image shows up and the image I save out as a jpg is blank. I imagine I'm not setting the bitmap data correctly but can't figure out what I am doing wrong.
Here is the code where I am converting it to a bitmap:

So here I am getting streams from facebook post. So when any facebook application's long image link I am getting that I can't display in Image container, this is not displaying image.

When I have seen this in Charlse Debugging proxy then it is displaying 403,Forbidden error of image.
What I have to do is upload some images to a server, which is OK, but before uploading I must downsize this images by reducing their quality and width/height. I've found many information about the class JPGEncoder, but I couldn't make it work.
View 2 RepliesI tried on Flex 3, facing issue with uploading JPG/PNG image, trace readUTFBytes would return correct bytes length but tmpFileContent is trucated, it would only appear to have upload just 3 characters of data to the server through PHP script which made image unusable.I have no issue for non-images format. What is wrong here?

I have been programming using flex 4 on adobe flesh builder 4 in order to create a website. The site require a connection to java and hence I decided on using blazeDS, in order to do so I updated the flex project's properties and set the flex server from "noneother" to "j2ee" as is required for the use of blazeDs. Ever since this change the site no longer runs as it should, as all the images are not being displayed and all action listeners are no longer working.(The problem is due to the flex server as when I changed it back to none the site worked fine)I need the j2ee server, and cant go by without it.
View 1 RepliesI have an AS3 swf which users can upload jpg images to my EC2 instances which sit behind and Elastic Load Balancer. The jpg images are converted into bytearray data and sent using URLLoader.load(URLRequest)I make 2 calls when uploading, one to upload a large version, then another to upload a thumbnail version. A PHP script to which the bytearray data is uploaded converts this to a file using file_put_contents($destination,$GLOBALS["HTTP_RAW_POST_DATA"])Is it possible to combine these two requests into a single request which contains both the bytearray data for the large and thumbnail images and 'split' the HTTP_RAW_POST_DATA to create 2 files at the server. This would be better than uploading the bytearray for the large version then using something like ImageMagick to resize the resulting image into a thumbnail which I realise is another option.
View 1 RepliesI am wondering if it is possible to get a url to some image on google, say a square (jpg/png/gif), and process it into an SVG. Is this possible?
Right now I'm getting ByteArray data in Actionscript by making a URLRequest('image/on/google'), with dataFormat="binary". I don't think Actionscript could handle/do it, but maybe it could. I'm also good with Ruby, so perhaps is this possible with Ruby?
If so, any sample code/libraries to get started?
I guess another way to ask it is, how do I convert a Bitmap to a set of Vector Paths like Adobe Illustrator does?
I am wondering if there is any way to determine the width and height of an image that is decoded to a ByteArray.For example in the below, any way to determine these values for data?
var data:ByteArray = new ByteArray();
data = encoded_image.decode(byteArrayData);
I have problems with the load of an image from a ByteArray, I can't get the image size, witch I need to position the image. Strange thing is that the image is showed to me correctly.
My code is something like this:
ActionScript Code:
var data:ByteArray; //Here are saved the raw image data (JPG, PNG, etc)
...
var img:Loader = new Loader();
img.loadBytes(data);
[Code].....
I have been searching in forums and I couldn't find an answer so I thought maybe I should ask.
I wrote a script that allows user to select a local file, which gets resized if it exceeds the width/height limits I specified, and finally this file gets uploaded to the server.
In documentation it writes the same max sizes for BitmapData and Loader:
Quote:
In AIR 1.5 and Flash Player 10, the maximum size for a loaded image is 8,191 pixels in width or height, and the total number of pixels cannot exceed 16,777,215 pixels. (So, if a loaded image is 8,191 pixels wide, it can only be 2,048 pixels high.) In Flash Player 9 and earlier and AIR 1.1 and earlier, the limitation is 2,880 pixels in height and 2,880 pixels in width.
So what I need is to check the file size (width and height) before I attempt to load the bytes of the file into a loader. I'm limited to the ByteArray that I get by the load of the file via a FileReference instance.
Has anybody seen a source where you can get that data out of a ByteArray prior to loading it into a DisplayObject?
Is there a way in actionscript to convert an image to text data, i want to do an air app that converts an image to text and saves it in a text file, i also need a way to convert that text back to an image,
View 1 RepliesI'm capturing an image from an swf and transmitting it as a byteArray to a php file. Everything seems OK in capturing and sending the data but the final image doesn't display and says it is corrupt.
I'm not sure if i need to do something to the byteArray or if there is something wrong on the php side that is causing the error?
I'm using stuff I've found on other posts and haven't tried JPGEncoder yet which is mentioned in some of those posts and examples. I thought it would be simple enough if it was just a getPixels() and wouldn't need JPGEncoder.

// owl is mc with image on stage
var bitty:BitmapData = new BitmapData(owl.width, owl.height);
