Dynamic image load with MovieClipLoader

I'm trying to load five images from five URLs. If I use the
documentation exactly as is, it works fine. Problem is, I don't
want to createEmptyMovieClip, I want to use an existing one that's
tucked inside a movie instance. Also, the images coming in are of
unknown size, but have a standard 4:3 size ratio. I'd also like to
scale them down to 180x120 after they arrive. Any help would be
greatly appreciated.
The code below only loads one image (which isn't working). I
will eventually need it to load five different images.

Dynamic text that doesn't have embedded fonts won't respond
to tweening, alpha, etc. So you need to embed the font(s). There
are a couple of ways to do this depending upon what you are doing.
But most likely you can just select the text field and click the
font button on the properties panel and select embed. Also I would
recommend that you use _visible=false instead of alpha for this
effect.
I'm not sure what the second go-round is. Can you explain
that a bit better? You should be able to use the same loader, so
I'm not quite sure what is going on. Again, look for some helpful
places to put some traces and see if you can figure out what is
going on. Remember that generally Flash does what we tell it, not
what we want! So if you can find the places where you are telling
it to do things you can figure out what is happening.
Also I'm not clear on what is going on with the variables and
text. Generally I would recommend against using the variable
property of text fields. That is a leftover from the Flash 5 days
when you couldn't work directly with dynamic text fields. Instead
give the fields instance names and then assign the text with the
text property.
myTextField.text="some value in here";
myTextField2.text=someStringVariable;

Applying filter to images loaded with movieClipLoader

Hello,
I am building a product gallery and have a number of rather
large bitmap images that I am loading with movieClipLoader. I need
to apply drop shadow filters to them when they are loaded. I have
tried several methods of going about this without success. One
method was putting the loaded images into a movie clip with
createEmptyMovieClip, and then applying the filter dynamically, but
I couldn't seem to get it to work- the filter never appeared. I
then tried applying the filter to the bitmap itself with
bitMapData, but because I was not loading the bitmaps using
bitMapData itself (I think) I wasn't able to get that method to
work either.
Does anyone have a suggestion or a recommendation for me?
Thanks very much for any advice.

Were you doing it after the onLoadInit event in the
MovieClipLoader's listener?
Try doing it that way if you haven't. One option I use for
dynamic image loading is to create and empty holder clip - use that
for placement and create another empty clip inside that one that I
use as the loading target... I think this should work if you set
the filter at the level of the first 'empty' clip. I had to use
this approach a number of times because I was using a tweening
engine based on movieclip prototype extensions (old hat I know) and
loading new images kicked out the extended functionality from the
clip the images are loaded into. That doesn't happen to the clip's
parent... hence I think it might work also for what you want to do.
Another thing to watch for is that you can't do bitmapData
copies of images from a different domain unless you have
crossdomain policy support - you can set it up so this works. I'm
not sure if this affects filters though.

Interface frozen with images loaded with Loader()

Hi all,
I am trying to create a web app that allows the user to load an image from a local folder and process it with some image processing. I was able to do that with FileReference and Loader.
I am using an asynchronous shader to process the image and it seems that when the image is loaded locally the interface is locked out for a second or so before showing the result. However, if the image is embedded this does not happen and the image is updated instantly with the result.
I don't really understand why an image loaded with a loader has this lag and an embadded image does not... Can anyone help?
Thanks.

Dynamic class loading with Webstart

Hello !
//within the jar-file at the webstart-directory
public interface MyFrame{
public void createFrame();
//within the jar-file dynamically downloaded
public class MyExtFrame extends JFrame implements MyFrame{
String className = "MyExtFrame";
ClassLoader cl = ClassLoader.getSystemClassLoader();
JarClassLoader jarLoader = new JarClassLoader (cl, jarFile));

client.createFrame();
This is the code i'm using and i've encountered following problem, if i put this code into an application without webstart, anything works fine, but with webstart i'll get a: java.lang.NoClassDefFoundError
Then i've put the MyFrame-classes into the downloaded jar-file, but this won't work either, i'll get a ClassCastException.
What do i have to do, to become it working ?
Thanks for any conclusions and help.

Rotating image loaded with CameraRoll

I'm having trouble working out how to rotate an image loaded using CameraRoll on an AIR for iOS app.
This code below works fine (displayImage() is called when CameraRolls media event returns completed, and imageArea is the scrollPane where the image is shown.
     function displayImage():void
     var image:Bitmap = Bitmap(imageLoader.content);
     imageArea.source = image;
The image loads just fine untill I try to rotate it:
     function readMediaData():void
     var image:Bitmap = Bitmap(imageLoader.content);
     var imX:int = image.width;
     var imY:int = image.height;
          if (imX>imY)
              image.rotation = 90;
     imageArea.source = image;
With the second version the image seems to load because the scroll bars expand to the size of the image I choose, but I don't see anything on the stage.
What am I doing wrong?
Any suggestions would be really appreciated.

I added the new width back to images x position but no joy; no matter what x & y I set the image to, it cannot be seen. The scroll bars expand exactly the right amount for the 'invisible' image, regardless of it's x & y positions as well (you'd think if the image was out of the scrollPane the bars wouldn't adjust like that. I'm not doing something right.
I'm stumped on this but I'll keep trying things. Thanks for your help and the lead, I appreciate it and it may be part of the problem, but there seems to be a different problem as well.

Problem using parameters in dynamic image loading

Hello experts!!!
I am using Crystal Reports 2008. I am trying to make use of a class servlet application that returns an image based on a number of parameters. I have put a formula behind a default image that should access the servlet and change the image at runtime.
This works fine in the CR2008 designer. However when it is published to my webapp, it doesn't work.
The problem is that for some reason, something somewhere is removing the '?' before the parameters in the URL.
My formula

Dynamic Class Loading with interface

Hello
I would appreciate any help on the following problem.
I need to load all classes in a particular directory and its subdirectories (top directory is known but not in the classpath) which implement a predefined interface. At the moment I am using a lot of reflection to accomplish this and believe it can be avoided somehow using the fact that I know these classes have to implement a predefined interface.
At the moment, I am searching through the directory and subdirectory, loading all names of classes into a vector using a custom URLClassloader, and then load all classes in the vector into modulecontainers to populate a defaultmutabletree which is displayed on the gui.
I'm sure that knowing the interface means there's a more straightforward way.
Thanks in advance.

Dynamic image loading in a JPanel

Hi,
I've created a JFrame which includes a JPanel and would like to dynamically add images to the JPanel (for a space invaders game). I've been getting the JPanel graphics object casting to Graphics2D and then passing it to the Actor class constructor where the sprite is loaded as a BufferedImage and then called drawImage on the Graphics object but the sprite does not display. It's been suggested that I need to use a new JPanel for every sprite that gets loaded, but this would seem to be less efficient.
public class NewJFrame extends javax.swing.JFrame {
    public static NewJFrame root;
    public NewJFrame() {
        initComponents();
        root = this;
       Graphics2D g = (Graphics2D) jPanel1.getGraphics();
       new Actor(g);
public class Actor {
    public Actor(Graphics g){
        try {
        BufferedImage sprite = ImageIO.read(new File("/Users/administrator/Desktop/image.jpg"));
        g.drawImage(sprite, 0, 0, null);
        } catch (IOException e) { System.out.println(e);}
    }Thanks

The problem with doing it this way if I understand correctly is that if I overload the paintComponent method of the panel I'm trying to draw on this will be static i.e. you can't pass parameters (such as a the url of the graphic to load or number of graphics to load) to the paintComponent method (it only accept Graphics g as a parameter). In other words the panel can only be drawn on once.

Question about dynamic class loading with thread built in

Hi ,
I am trying to load a class with a thread built in from the network.
I write my network classloader, convert the class to a byte array and transmit over the network using socket. This step seems fine but when I tried to load the class at the receiver, some exception happens,"
the reported exception is that :
Exception in thread "Thread-2" java.lang.NoClassDefFoundError: SampleProject/Application$1
my class name is "SampleProject . Application", the $1 I think it may refers to the thread built in the "Application".
Could any one give me some hint for how to dynamic load such class file with thread built in over the network?
Thank you!
Best Regards,
Song Guo

Exception in thread "Thread-2"
java.lang.NoClassDefFoundError:
SampleProject/Application$1That means that the receiving end can't find an anonymous inner class which you have in the Application class. (The anonymous clas is given the synthetic name 1). Check your bin/classes folder you will have a class there with the name Application$1.class

Image loaded with Loader doesn't render

I have created a web service that pulls images (gif,jpg) from
the database and base64 it for sending across the wire. The flex
application then decodes and renders the image. The Image is not
being scaled correctly. IT will not adhere to the dimensions of the
ImageBox but rather stays at the original fixed size. If I embed
the image into the application everything works correctly. But if
the image is decoded then sizing goes out the window.
The image overflows the Image box and takes up the full size
of the image. Zoom, rotation, etc. do nothing to the image.
Any help is appreciated...
Example Code:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="

var base64:String = "R0lGOD..."; // Get base64 from web
service call
var decoder:Base64Decoder = new Base64Decoder();
decoder.decode(base64);
// Load image into container
var loader:Loader = new Loader();

Hi Dmitri,
Thank you for the prompt reply, your question about the jpeg content was a helpful pointer.
I solved the problem, it had nothing to do with flex, it was all on the java side. The image was obtained from converting a TIFF to a JPEG, the conversion was failing and the flex loader was receiveing a tiff and it did not know how to display it.
The java problem was kind of interesting, I'll post it here as an FYI in case anybody cares :
On my server the first writer returned by ImageIO was an instance of JPEGImageWriter and on the other servers was CLibJPEGImageWriter. And it happens that only JPEGImageWrite can write the type of TIFF that we are having.
The fix was to iterate through all the writers and pick the instace of JPEGImageWrite, instead of the first one found.

Jpeg image loaded with Loader- loadBytes() does not display when app is deployed on remote server

I am loading a JPEG image from the server, using the Loader->loadBytes() and that works when the app is deployed under my local Tomcat server. When I deploy it on other servers the image is not displayed, instead of the image I see II*
On the server side I have java, Spring, BlazeDs and I use RemoteObject on the client.
The code that loads the image looks like below:
private function imageLoadResultHandler(event:ResultEvent):void {
    var result:ArrayCollection = event.result as ArrayCollection
    var bytes : ByteArray = result.getItemAt(0) as ByteArray;
    _loader = new Loader();
    _loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loaderCompleteHandler);
    _loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, loaderFaultHandler);
    _loader.loadBytes(bytes);
private function loaderCompleteHandler(event:Event):void {
    var loaderInfo:LoaderInfo = event.currentTarget as LoaderInfo;
    var img:Image = new Image();
    img.source = loaderInfo.content;
    myPanel.addChild(img);
<mx:RemoteObject id="ro" destination="imageLoadService">
     <mx:method name="loadImage" result="imageLoadResultHandler(event)" fault="faultHandler(event)" />
</mx:RemoteObject>
Any help with this problem is much appreciated.

Images loaded with a random number

Hi All,
I have made a flash movie as seen at
http://www.coffeemamma.com.au
and would
like to change the following:
I'd like to generate three random numbers from 1 to 5
inclusive but I want
to ensure that each number is different - e.g. 2, 4, 1 (not
2, 4, 2). I know
how to generate ONE random number, but I'm stuck on comparing
them to see
whether they are the same (and if they are, then generate new
numbers until
they are unique).
With the three numbers I would like to load images based on
those numbers -
e.g. '_image_2.jpg' then '_image_4.jpg' then '_image_1.jpg'.
This part is
fine IF I can generate the numbers.
I'd also like to have the images come to the front when they
are hovered
over with the mouse and then to go 'back' to their original
position when
the mouse moves away. This I'm completely stuck on.
I'd also like to be able to put the newly loaded images into
certain
positions (as per the example) rather than only loaded to
(0,0) coordinates.
I also want to be able to have the images masked as they come
in (as per the
example) in order to avoid white corners on the top images.
I also have a page as per
http://www.wasabi.org.au/wodonga.shtml
which has
some of the functions I want to use, but I can't seem to get
some of the
functions working in my new movie...
Many thanks,
Bruce

I recommend to read      at least the first two "introduction articles" from sun's Java >Card homepage: http://developers.sun.com/techtopics/mobility/javacard/articles/
Thanks a lot ... really interesting. I learnt already alot with that !
I am sorry but the code you posted is J2SE-code, not JavaCard code. The JavaCard >environment is very restricted:
No Integer (most cards don't even support the simple "int") and no String class.Oops :) ... i knew something was wrong hi hi
This is my new code, it seems to work:
    /* SEND_CHALLENGE */
    private void sendChallenge(APDU apdu){
    byte[] apduBuffer = apdu.getBuffer();
    RandomData random = RandomData.getInstance(RandomData.ALG_SECURE_RANDOM);
    random.setSeed(randomArray,(short)0,(short)32);
    random.generateData(randomArray,(short)0, (short)32);
    Util.arrayCopy(randomArray,(short)0,apduBuffer,(short)0,(short)32);
    apdu.setOutgoingAndSend((short)0, (short)32);
    }Thanks a lot
I'am going to be back soon for some more questions i think !

Dynamic image in header

Hello,
I've been starting to use Livecycle designer (version 8 it seems) a few weeks ago and I am currently confronted to a problem that I can't to solve.
Basically, I need to create a Fragment that serves as a header for multiple documents.
This Fragment contains an image field that changes depending on certain values on my form and of course, being a header, it is placed in the master page.
Now, for some reason,the fragment works if my it is placed in the main page, but doesn't display any image if I place it in my master page.
I have been using the following code to load the image:
imageField.value.image.href = "../Pictures/myPicture.png";
Alternatively, I have also tried to use a dynamic image field with the same code, and although it displays the picture in Designer (even when in the masterpage), the pdf is "corrupted" when I load it from Livecycle.
Am I taking the wrong approach here? Is there anything that I can do?
Thank you for any light you can shed on the matter.

Hi,
Don't have a complete answer, but you might get some indication for working with images here: http://assure.ly/mcFrC6.
You should also have a look at John Brinkman's post: http://blogs.adobe.com/formfeed/2009/11/linked_vs_embedded_template_im.html.
If you are using an ImageField object on the Master Page you might need to set its binding to Global. So that as new pages are rendered on the form, the image will be displayed.
In relation to the href, I believe that you are hitting a security restriction.
I am not sure how best to get the image in from LiveCycle, maybe someone else will have a better view.
Good luck,
Niall

Button to load dynamic image in interactive form webdynpro for java

Hi all
i tried to use image field to load dynamic image as shown in the online interactive form tutorial
and it worked for test but when try it with view appears inside viewset it doesnt....
so i think if we could call the image after render by pressing a button inside the form it may work
but the problem is i have no idea about how to implement such solution ,so if any one has any idea about how to implement such solution i will be thankful if he can share me the solution.
thanks.....
