Load Images Bundled in a SWC At Runtime?

If I have a SWC that has some images bundled into it that was
created using the compc compiler like:
compc -o=images.swc -include-file img1.png img1.png
Is there a way to load it into Flash at runtime and use the
Images?
The reason I'm doing this is that I want to allow an image
library to be dynamically loaded at runtime that has images which I
do not have at compile time.

Use code tags to post codes -- [code]CODE[/code] will display asCODEOr click the CODE button and paste your code between the {code} tags that appear.

Problem in loading images at runtime

hi ~
I am facing some problem in making a dynamic flash
application. Actually i have to loading certain images from a
remote database at runtime into a pre-existing flash file. i have
tried it by putting static images and converting them movie clips.
urgent help required.
Thanks,
Varun TEkriwal

you want to load an image? you want to load an mc? first step
in successful coding is asking the right question.
and your question was?

Load images in runtime

Hi.
I am trying to create empty movieClips in runtime and load
images to them. My problem is that it results in some performence
problem.
The thing is that I load images from a digital camera and
each image is about 1MB. First of all, that takes a long time to
load. Then i change the _x/_y scale so that the images becomes
thumbnails. (Does the image remain 1MB when i use scale, or does
Flash make the filesize smaller?)
Next problem is that i want to use "duplicateMovieClip" on
those thumbnails and start drag the copy. It doesn't seems to work
with "duplicateMovieClip" on dynamic created mc so I need to make a
new emptyMC and load the image into it. That takes about a second.
Is it possible to create a movieClip to the library in
runtime and then use attachMovie() for every new instance that i
want to create?
I hope you understand my problem.

Hi,
> (Does the image remain 1MB when i use scale, or does
Flash make the filesize smaller?)
It's the same picture, just scaled down, so it will remain 1
MB. Maybe there are thumbnail versions stored in the camera, which
could be loaded instead the full image. Not sure about that...
> It doesn't seems to work with "duplicateMovieClip" on

the image into it. That takes about a second.
Yep, dynamically loaded content cannot be duplicated. Flash
should load it the 2nd time from the cache though, so it should be
faster than the first loading.
> Is it possible to create a movieClip to the library in

> want to create?
No, afaik you can't add items to the library at runtime. You
could add an MC in the Flash IDE and use this with attachMovie(),
but I doubt that this will be faster than createEmptyMovieClip().
Could be worth a try though.

How could I load image via a Form when it is in runtime by not using default block

1. How could I load image from my local computer to the database via a Form when it is in runtime?
2. And how to display the image stored in the database on a Form ?
Thanks buddy ~
A nice member answered this question already, but I want to know how could I do it by using manual create block instead of using database item directly~
Could anyone help me pls~

This is the only way I know right now:
1) Create this table
SQL> desc av_data
Name Null? Type
BLOB_ID NOT NULL NUMBER(10)
BLOB_TYPE NOT NULL VARCHAR2(10)
DESCRIPTION NOT NULL VARCHAR2(25)
BLOB_DATA LONG RAW
2) On form create a button with this 'when-btn-prssed' tgr:
DECLARE
     v_dirname          VARCHAR2(255);
     v_filename          VARCHAR2(255);
BEGIN
     v_dirname := 'C:\';
     v_filename := get_file_name(v_dirname, NULL,
     'Bitmap file (*.bmp)|*.bmp|'                    ||
     'JPEG file (*.jpg)|*.jpg|'          );
     IF v_filename IS NOT NULL THEN
read_image_file(v_filename, 'ANY',
'av_data_image.blob_data');
     END IF;
END;
3) Add this pre-insert trigger too :
:av_data_image.blob_type := 'IMAGE';
Sorry if this is not exactly the answer you're looking for.

Part 2: Load Image from URL into Dynamic Text Box - goodinson.snapshot

I have a flash file where a user can add an image url into a Dynamic Text Box (image_in.text) and the image will now appear in the flash file.
I am using goodinson.snapshot as featured in this article: Saving Flash graphics as image files at runtime | Adobe Developer Connection
This application works fine (graphic is generated and downloaded) only if a user chooses an included graphic in the flash file (loaded externally) or if I declare a url inside the flash file for the load image variable (var image_url:String = "http://website.com/image.jpg";).
However, if a user enters an image url into the Dynamic Text Box (image_in.text), which the flash does successfully load, the download image function no longer works!
Is this a security bug in flash itself? Or am I missing a code tweak somewhere?
If an FLA that does this already exists somewhere, let me know.
Thanks in advance for your help!

Thanks for your response!
The image urls are on the same domain as where the swf is.
I don't understand how declaring the variable as the url is different from declaring it from the value of a dynamic text box... it's the same url, but only one method works, shouldn't they both work?
var image_url:String = "http://website.com/image.jpg"; works..
var image_url:String = image_in.text; does not work, even though the value for image_in.text is identical to the one in the example above.
Since they are all on the same domain, this should work, right?
Thanks again.

Loading images inside applet JAR

Hi
This is my issue: I have an applet which contains images inside the applet JAR. I want to display these images in my applet, but apparently due to browser access restrictions, I'm not allowed.
My first code was like this:
//security restrictions on browsers do not allow getResource
ImageIO.read(MyClass.class.getResource("imgs/img.png"));
//getResourceAsStream should be allowed by browsers
ImageIO.read(MyClass.class.getResourceAsStream("imgs/img.png"));Both lines work when I execute the applet locally (command line / programming IDE), but when I deploy it to my web server, the resource "imgs/img.png" becomes a relative URL to my web application context (like /webcontext/MyClass/imgs/img.png). It works locally because the call to getResource returns a URL object with "file:" protocol, but I need it to look for my images bundled inside the JAR, not web hosted images.
I need to avoid making the applet look for these images as a web resource... how can I do it?
Thanks!

[http://java.sun.com/javase/6/docs/api/java/applet/Applet.html]
getCodeBase returns my web context, like http://myhost.com/mycontext/ , so it is pretty much the same as above.
Thanks for your replyThat is the way to load resources though. Hence back to my earlier statement about not being convinced it would not work, with this addition: It should work, assuming you actually do have the resources properly located with the web app, whether they be in a jar, or loose files relative to where the web app is. My guess at this point is that they are not.

Adobe Flex unable to load images from Amazon S3

I have a flex 3 app that is attempting to load images from Amazon S3. The images fail to load, so I fired up debug mode. In debug mode, the images load, but I also get the following output in the debugger:
    *** Security Sandbox Violation ***
    SecurityDomain 'http://mybucket.s3.amazonaws.com/logos/mylogo.png' tried to access incompatible context 'http://localhost/myapp/bin-debug/index.html?debug=true'
I have added a crossdomain.xml file into the root of my bucket as follows, but this does not seem to help:
    <?xml version="1.0" encoding="utf-8" ?>
    <!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
    <cross-domain-policy>
      <site-control permitted-cross-domain-policies="master-only" />
      <allow-access-from domain="*" />
      <allow-http-request-headers-from domain="*" />
    </cross-domain-policy>
I then tried the following:
Security.loadPolicyFile('http://mybucket.s3.amazonaws.com/crossdomain.xml');
Security.allowInsecureDomain('http://mybucket.s3.amazonaws.com/');
Security.allowDomain('http://mybucket.s3.amazonaws.com/');
At this point, it seems that there are not any more errors reported in debug mode. However, when not in debug mode, then the image still does not load.
Am I missing something obvious here?

If you are not getting creationComplete in release vs debug builds, it is best to try to identify the differences between the two runtime environments.
Is the URL to the SWF the same? Some folks find that their release folder is missing some important file.
Is the URL to the HTML wrapper the same? Some folks launch their debug from file:// and their release from http:// which have different security rules
Is the launch step the same? Some folks launch their debug from FlashBuilder and their export via some other mechanism. This can alter the initial size of the app and that difference can cause some apps to get into a “layout loop” and never hit creationComplete. To find out if you are in such a loop, report calls to updateDisplayList, and measure() on various compoonents and see if they keep getting called.
Is there a timing difference? Some apps may have subtle timing dependencies that change when the release build runs faster.

Issue in loading images from Apache webserver in JSF image tags on WLS 10

I have configured the apache webserver2.0 for passing on the request to weblogic 10.0. I have images in apache webserver. In my application on weblogic i am using JSF f. In JSF for <h:graphics> tag i am not able to load images from apache webserver. issue we found out that it prepend a context url on it.
          pls provide if u have any solution for it.
          Edited by neerajr at 11/16/2007 3:33 PM

Hi, Neeraj,
          Are you actually telling <h:graphicImage>? As per html_basic.tld, the "uri" attribute is context-relative.
          Using "value" attribute instead of "url" attribute may be helpful. Something like
          <h:graphicImage id="fooImage" value="http://www.foosite.com/image/foo.jpg"/>
          This should work on WLS10.0 if you are using the JSF library bundled in it.
          Thanks,
          -Fred.

I think the new error you saw was due to the cross-schema issue on 10.1.0.2/10.1.0.3 (as described in another thread on creating pyramids).
You should connect as system to grant the permissions. With 10.1.0.2/10.1.0.3, importFrom should be called from the same schema where the GeoRaster tables are defined. (Upgrading to 10.1.0.4 or higher if you want to perform cross-schema operations.)
Other than the connection part, your scripts looked OK. Please make sure that the file with the specified file name does exist and is on the same machine where the database is running. Note that even if the grant_permission call is executed successfully, it does not necessarily mean the following file operations will always succeed. For example, grant_permission can be called successfully on a file that does not even exist. If a file with the specific name is later created, no permissions are granted on the new file. The case with the schema 'GIS' is similar. You need to make sure that the schema 'GIS' and the file do exist before the grant_permission call; and grant_permission can be called repeatedly, if necessary.
Hope this helps.

Sizing Dynamically loaded images

I've loaded images into a project at runtime they show, but
when I try to resize them they are set as a percentage of the
original size and not the pixel size. I've tried using setProperty
and object._width= and object._height=. Every place I've read
anything about the _width and _height properties says it should set
those values in pixels, but for some reason it's percentage for me.
I'm loading .jpg images
have flash 8 pro
How can I set the picture width and height in pixels?

you need to ensure that the picture is loaded(preferably
using MovieClipLoader.onLoadInit) before resizing.

If I set Firefox to refrain from loading images automatically, how can I view a single image, or a single page's images, without having to enter the site in the Exceptions list, only to go back and remove it when I'm done?

I was hoping for a hotkey option or button on the toolbar to load images for a single page for a single session at a time. Turning off images really saves bandwidth and speeds load time on websites, but sometimes I'd like to view the images on a page, but only for this session. Is that possible, or do I have to go to the Exceptions page and allow a specific domain or page to load images and then go back and remove that domain or page when I'm done?

Using Firefox to access facebook chat Button or online friiend chat button generates a Black screen with CANNOT LOAD IMAGES and no chat window opens.

This does not happen in other browsers and it happens on a variety of computers I have access to and would seem to be a common problem but I can find no identical cases in my searches of
Firefox , Facebook or windows help or Google search. My home machine is only a P2 with WINXPCORP but works fine and I have done all updates but still have this continuing problem every time I try to use Firefox
to access Facebook chat but it does not happen with IE or chrome
The response to clicking on chat button or friend chat is a black screen with small center square box with blue title bar that says
'' VIEW IMAGE FULL SCREEN - (42) FACEBOOK X""
center of box is ""! "" mark in yellow triangle and wording
"" CANNOT LOAD IMAGES ''' OK
clicking on OK returns to facebook page but no chat opens.
Some times |VERY RARLEY if as the page loades you click on
chat button with 1/2 second of it appearing chat will open.

Why won't safari load images and connect to websites?

We've had this problem intermittently for several months. When visiting SOME websites (though never the same ones twice) instead of loading images, it comes up with a blue question mark in a box. if we try to reload the page, it will do one of two things: it will either reload exactly the same, or, it will reload in a format that shows vertical written links - no images. it almost looks like programming language, but it's readable.
also, when we go between links, we often get the message that "safari can't find the server". this is, again, erratic. If i try to go directly to the same website by typing in the address in the bar, i will get the connection. (so, if i go from youtube for example to try to connect to another website it won't work. but if i try to go directly to that website by just typing in the address myself, i can get it.) as i said, it doesn't always happen, but when it does it's a real pain!
lately, i've had a new problem too, which seems to relate: when using hulu.com, it will not load the show saying it is unavailable and to clear my cache. I've done that... and it still won't reload. yet, when i go to google, and search hulu.com, and go to the website that way, i can get to the show page no problem. Or, i have to quit safari and then go back to hulu and, again, no problem.
sometimes we can go for days without the problem, sometimes not.
any ideas on how to help this problem would be MOST appreciated! thanks

blue question mark in box
Go to Safari > Preferences then select the Appearance tab. Make sure Display images when the page opens is selected.
For server issues, try turning off the router for a few minutes, then restart it.
Hulu requires the Flash plugin. Uninstall your current copy of Flash, then reinstall > Troubleshoot Flash Player | Mac OS
Try emptying the Safari cache more often.
And reset Safari. From your Safari menu bar click Safari > Reset Safari. Select the top 5 boxes, click Reset.
And how much free space on the startup disk? Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure there's a minimum of 15% free disk space.
Try Safari in another user account. Same problems there, then log back into your admin account, launch Disk Utility. /Applications/Utilities
Select the startup disk in the panel on the left then select the First Aid tab.
Click: Verify Disk (not Verify Disk Permissions). If the startup disk needs repairing, follow the instructions for Using Disk Utility to verify or repair disks

How do i load images from a folder?

Hello everyone,

Loading Images into Applets

I've been having problems loading an image into an Applet. I've found that when the getImage() call is put into the init() method it loads the image fine, also implementing an imageUpdate call. However, now I'm trying to expand on this by putting it into a button click, it hangs indefinitely while waiting for the image to load.
Another interesting point I've noticed is that the Canvas subclass ImageSegmentSelector uses a PixelGrabber in its constructor to put the Image into a buffer - when this class is created from the imageUpdate() call, NOT the init() call, the grabPixels() call hangs indefinitely too!!
Any feedback, please,

Sorry, thought this had been lost.
You can load a file if the applet itself is run from the local filesystem - it loads it fine from the init(), but not otherwise. But I haven't got the applet to run from a browser yet without crashing (it's OK in the IDE debugger), so that's the next step.
