ActionScript 3.0 :: Loading Image Using Loader Class
Jan 17, 2010
I'm trying to load images using the loader class but it doesn't seem to ever trigger the complete event (in this case anyway). The images are only 16x16px images from the local machine, so it should take no time at all to load. I use the totalImages variable as a counter; as an image is loaded, it subtracts 1 from it. Once it is 0, all images are loaded. I can create an instance and it goes as far as tracing "Begin loading images", but that's it. No errors in the console either.
PHP Code:
package lib{
import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.display.Loader;
import flash.geom.Rectangle;
import flash.net.URLRequest;
import flash.events.Event;
public class Frame extends Bitmap{

[code]This script is for a loader image gallery in flash, as part of a class assignment. What happens is that in flash, when I open the swf file, the initial image (images/nair_evanescentautumn.png) will load fine. However, clicking on any thumbnail image (including the exact same images/nair_evanescentautumn.png), will result in an error saying the file cannot be found.I cannot figure out why it is doing this... I've tested it over. Clicking each thumbnail does go to the correct position in the two separate functions. All said full-size image links are in the folder images/, and replacing the initial loader image will load the other images in place of the default one. However, clicking on any thumbnail still results in URL not found, even though everything works correctly.[code]Before anyone asks why I'm putting this kind of content into a flash site, I'm not--this is only for a class assignment. I'm just trying to figure out why my images aren't loading right when I'm only doing the exact same thing in the functions as I am on the other pages.Of note, commissions.swf has the exact same feature, just with swf files loaded instead, and it works perfectly fine. home, traditional, digital, and photography all have the image gallery, and all have the same issue (I only referenced one page because if I can fix one page I should be able to fix all of them).As for the artworks, they are all my fiance's. The website design was built for her, and I used the website design for this project because I didn't want to have to build an entirely new interface design. Since the project also required a gallery, I felt that this interface would work just fine.

I need to create a gallery to load images and display them. This part is fine:
/**
* @variable image_name to store the name of the selected item
*/
private function showimage(evt:Event):void
[Code].....
where imgMain is the id the image component.
But, I need a small twist. A transition image i.e. loading image should be displayed while the the image is being loaded.

I've tried adding this loader as a child of several different sprites but it only ends up in one of the sprites (must be removing from the other sprites display list automatically).How can I duplicate that image in the loader into multiple sprites?e.g. (note don't worry about making sure the icon is loaded, pretend I wanted to Event.COMPLETE before adding to
var icon:Loader = new Loader();
icon.load(new URLRequest('image.png'));
var iconA:Sprite = new Sprite();

I'm working with Loader class in as3 and there comes some really strange problem. I have two swf files, one loading the other. In the first one, I have codes like this:
var loader:Loader=new Loader();
var context:LoaderContext=new LoaderContext();
context.applicationDomain=ApplicationDomain.curren tDomain;
var req:URLRequest=new URLRequest("Untitled-1.swf");
loader.load(req);
loader.contentLoaderInfo.addEventListener(Event.CO MPLETE,onCPL);
function onCPL(e):void{
trace("finish");
addChild(e.currentTarget.content);
}
And the second one, with the name "Untitled-1.swf", doesn't seem to work in the first one. I find out that as long as there are ANY codes in the second swf file, the first one will repeat tracing "finish" endlessly.

I'm trying to resize a .jpg file that I'm loading in the loader class, and I can't get it to work. Here's the code I'm working with. (Note: I had to cut the URL to the jpg out because the forum blocks me from posting URLs with images!)
ActionScript Code:
getURL = new URLRequest("*URL to a jpg goes here*");
// Load slide image from URL

I'm not sure whether to post this in a flex forum or here,but since the error is generated from AS3 code, I'll try it here.When I try to load a compiled flex swf with the loader class.As a test I tried 2 very basic programs:See the actionscript code in the attached code..As you can see I just load the swf without doing anything.I've found very few threads about this error, and even less solutions...Does anyone know if it's even possible to load a Flex swf?

i was loading a images from web for a polio page.. and for god shake, the uploading of image using Loader class for .PNG file alwz stuck at 13765 Bytes and Threw error saying the URL not available .. i was sure that the image was there and it loaded upto 13KB ... this was damn freaking.. i took hours tryin to debug it.. the fix was so simple.. the image file was to be renamed .png rather than .PNG and all worked fine... How come and from when Flash started treating .png and .PNG in different way and why the image loaded to 13KB and said invalid url..?

I've been trying to figure this out for the past couple of days and couldn't find a solution and Im sure its something I have completely overlooked on my part. I'm attempting to load in an external swf in my fla file using this custom loader class I created. I keep receiving this error in an attempt to load the swf, which is in the same directory as my fla file that is loading it:
TypeError: Error #2007: Parameter url must be non-null.
at flash.display::Loader/_load()
at flash.display::Loader/load()
at com.proj.load::SWFLoadClass()
at test_fla::MainTimeline/frame1()
Code from SWFLoadClass.as:
package com.proj.load {
import flash.display.Loader;
import flash.net.URLRequest;
import flash.events.Event;
import flash.display.MovieClip;
[Code] .....
Code in fla file:
import com.proj.load.SWFLoadClass;
var l:SWFLoadClass = new SWFLoadClass("colorPicker.swf", 0, 0);

I'm trying to create a class that loads images dynamically with their corresponding thumbnails using an external XML file. It works fine in a lone fla file but when I try to make it into a class so I can reference multiple XML files, I get "A term is undefined and has no properties". Now, the class seems to work OK: I get a thumbnail displayed and when I click on it, it shows the picture but not the text and I get errors for both the xmlLoaded and showPicture functions as below. (I didn't paste the constructor function but it's there.)
It seems only one line is causing trouble in the xmlLoaded function (see asterisks) while multiple lines in showPicture are problematic. I know how to use the debugger to find the line of code but how do I wade through all the parameters to figure out what the problem is?
Code:
private var _imgText:TextField = new TextField();
private var _imgLoader:Loader = new Loader();
private var _containIt:Sprite = new Sprite();

I am developing a Image uploader using Flash 10. I am using Filereference object to browse images and Loader to show the image:
Sample code:
var tempFileRef:FileReference = FileReference(ev.target);
var oLoader:Loader = new Loader();
oLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onImageLoad);
oLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, onIOError);
oLoader.loadBytes(tempFileRef.data);
It works fine with .jpg and .gif files but when I browse .bmp or .tiff file, I am getting the error:
Error #2124: Loaded file is an unknown type.
Is there a way to load and display browsed .bmp images from desktop?

Using ActionScript can I do with my game, which is running in a browser, verify that the user already has the files needed to run the game installed on your computer? If he had these files do not need anything else that was born and can play the game immediately. If he did not have the files, they would be loaded so that the browser does not erase these files. So when he returned to play the same game day after,as the files already on your computer, nothing need be loaded.How do I remove one of the main memory image that was loaded using the Loader class? I tried using the unload () method but nothing happened.

I'm building an Adobe Air app that needs to load external images from different webservers. I have my basic loader function set up, but I encountered one server that wouldn't let me load it's images. it gave me the following error[url]...
After that I got in contact with the server's manager and he told me he had been working on some basisc hotlink protection for his images. He also told me that I could subvert this by supplying[url]... as the referrer when building the request headers.
First of all I found no trace of hotlink protection with online testapplications for hotlink protection. Secondly I have no idea how to set up what he told me with a simple Loader class function.[code]...

I'm trying to clone / duplicate an object loaded in at runtime via the
--
ldr = new Loader();
var mRequest:URLRequest = new URLRequest(targetFile);

technique. The problem I think I'm having, is in understanding what exactly the loader returns and how it can be used. after loading an image and tracing the result after the loader completes like this ...
trace(ldr.content); // - traces [object Bitmap]
I have a fuction I built that returns an arrar of clones / duplicates of a passed bitmap ...

Is there any way to make it check constantly (or more often), so the progres bar "grows" smoothly instead of "jumping"?

Sorry for the complicated topic. I got a .swf that loads in other .swfs. Rather than figuring out how to make a loader for loading .swfs I thought I'd just use a simple loader in the .swf I'm loading.
However, it doesn't work. It starts fully loaded but doesn't finish. Heres the AS:[AS]_root.stop();
PercentLoaded = _root.getBytesLoaded()/_root.getBytesTotal()*100;

My problem occurs when I try to load multiple images in one class in AS3.[code]My problem with this is, that every complete-method receives the same image. Sometimes they all get img1.jpg, sometimes they all get img3.jpg....I don't have any clue why this is happening.[code]Now the different Bitmaps and Loaders have distinct names and are called within the same method call. The event handlers now are inline.

I'm trying to make a URL-Loader Class to speed up my workflow, but I can't manage to make the images I am loading visible, turning their alpha to 1.
I use the following line to invoke my custom loader:
import com.ab.utils.Load
Load.Image(menuitem.holder_mc, menuitem.image, this)
[Code]....
Notice where I call a Tweener, trying to make my mc (_ITEM)'s alpha turn 1.
I tried thing like loader.content and loader.content.holder_mc, but to no avail.

I want to have an AS3 app load images from url supplied by the user. But I don't want a malicious user to be able to load an SWF file in place of the image, such as with an altered extension "maliciousSwf.png". Well, not sure how big a security threat that is above and beyond the ability of the hacker to decompile swf, but I think that ideally such behavior should not be allowed.
So, is there any way to prevent this? When people allow users to load images in their Flash apps, do they somehow guard against loading of SWF? Or is this really absolutely no big deal?
