I've seen mention of there being some security risk with loading images and leaving them in loaders. A few articles I've run across said that you should always draw them as a bitmap when the loading is done.
Is there any truth to this? I have a few loaders I have left in my project, do I need to hand their content off to a bitmap? What is the advantage of always having a bitmap represent the loaded image?
I am loading a fairly large image file and want to create a bitmap of the loader content. I want to then use this Bitmap and resize it according to the current dimension of the stage. However, I also want to keep the loader content as "originally loaded" as a reference in case the stage is resized and the user wants to view this particular image again. The way my AS is written as of now, I am manipulating the loader content. How do I not do this? How do I "copy" the loader content so I can manipulate the bitmap copy while leaving the loader content unaltered?
<AS>
var lightboxImage:Bitmap = new Bitmap();
function resizeLightbox():void{
lightboxImage = myLoader.content;
lightboxImage.width = myLoader.content.width;
lightboxImage.height = myLoader.content.height;

I'm writing a simple little test app consisting of 'main.as' and 'test.png', both within the same subdir on my harddrive. I'm compiling via command line with mxmlc, and testing via 'open with...' and Chrome. The code uses flash.display.Loader.load( "test.png" ) - but I can't access the loaded content (or even draw it to a bitmapdata!) due to security exceptions.
My goal is to get the image into something (preferably a bitmapdata!) I can draw to other bitmapdatas, as I understand this is fastest for gaming. I've tried all sorts of things, including creating a 'crossdomain.xml' that goes in the same dir as the above files (and doing the appropriate LoaderContext thing), tried various system.Security things and still no joy.
how to create an image gallery that loads external bitmaps. It also has some nice fade in/fade out effects using Tweener. I was wondering, what would I need to modify from my code to load MovieClips from the library instead of the external JPEGs.

In AS3, I am loading a png from a zip file (nochump's zip library through ByteArray to Loader). The png can be up to 45k pixels wide but only 120 tall. This creates a problem in flash, as images can only be ~8000 pixels wide. A possible solution would be to split the images into 6 columns somehow. This would probably need to be done in the ByteArray state, because the limitation is in Bitmap and Loader.
View 2 RepliesThe title describes the problem: Loader.load() is firing the INIT event, but in my listener it's reporting loader.content as null. The description for INIT event is "Dispatched by the associated LoaderInfo object when the properties and methods of the loaded SWF file are accessible."I'm loading a lot of JPG images, and 95 percent of the time it works fine; the init listener fires and reports valid loader. content.I absolutely need loader.content available because I need to set the bitmap smoothing property to true.I've tried using Event.COMPLETE and it has the exact same problematic behavior.
View 13 RepliesI'm have made some buttons (movie clip) and when I click on it, I want a file (home.swf) to load in a loader (mx.contents.loader) and I want the other buttons to do the same, all load into the same loader. I have no Idea how to do that. The way I have it set up now, the home.swf will load over the entire screen and that is not what I want. I just want the content to load into the loader and have its content change once I click on the other buttons. Here is a copy and past of that I have at the moment, I'm using Flash 8 to do it all.

How to remove a loader and its content using removeChild or any other way, I had removed the loader but its content still playing in the background i know that from the sound of the content.this is the my code for removing:
removeChild(getChildByName("SampleLoader"));
I have a main "shell" swf which, by clicking several buttons, will load/unload various external swfs into a Placeholder_mc which resides on the main timeline in Shell.swf In the documentation and tutorials I've seen a couple different methods, and I'm not sure I quite understand the difference, or at least the reason you would use one over the other...In the 1st method, you can just add the Loader object using the addChild() method:
Code:
var myLoader:Loader = new Loader();
var myURLRequest:URLRequest = new URLRequest("ExternalFileA.swf");
myLoader.load(myURLRequest);
Placeholder_mc.addChild(myLoader);
This will apparently add myLoader to the display list once it has completely loaded.The 2nd method, you supposedly can add the Loader.content; however, it appears you can only do this once the content has completed loading, so you need to incorporate an event handler with the contentLoaderInfo object:
Code:
var myLoader:Loader = new Loader();
var myURLRequest:URLRequest = new URLRequest("ExternalFileA.swf");
myLoader.load(myURLRequest);
[code]....
What are the pros/cons of adding the entire Loader object, as opposed to the Loader.content and vice versa?
Convert a particular area of the mc to a bitmap.

I'm loading a list of urls of pics from an fql query, then loading those urls with the loader class using this function:_loc is a MovieClip that holds the picture,[code]In onMyPictureLoaded I would like to get the bitmapdata out of loader.content and scale the image (smooth it too) that way, and then reattach it to the _obj MovieClip, but I'm having trouble reattaching that new bitmap to the object.It seems the problem is more to do with events and not having the ability to pass information (_loc, for example) from:loader.contentLoaderInfo.addEventListener(Event.CO MPLETE,onMyPictureLoaded); to the onMyPictureLoaded function.

Apparently, in order to make a bitmap transparent, one has to convert it to 256 colors from 24. I'm not sure if Flash puts it in 24 or 256, but because I can't create a transparency when using Bitmap() in my code, and from what I see displayed on the screen, it would appear that it uses 24 colors. Perhaps this is to keep things light. Nonetheless, is it possible to convert it to 256 colors?

I'm building an XML driven video player that will allow users to customize a wide variety of layout/visual features for the player, and one of the important features is letting them switch between a regular background image, and a tiled background. I've been playing around with various methods for tiling using the Bitmap class, and its been working fine, as long as I load the image from the library. However, when I try to load the image dynamically (i.e. through XML), it doesn't jibe.
Here's the code for the tile:
function tile() {
var tile:BitmapData = BitmapData.loadBitmap("linkageIDForBitmap");
this.beginBitmapFill(tile);
this.lineTo(Stage.width, 0);
[code]....
Again, if I write a variable which references the xml node, and use that variable in the loadBitmap function, it doesn't work. I'm assuming this is because the dynamically loaded tile doesn't have a linkage ID attached? Not sure how to do that...
My other thought is to simply load the tile into a movieclip (as I do with all the other content), and then convert the movieclip to a bitmap, then proceed as normal with the code above. I've searched the boards for a method to do this, but have come up empty.
I am having a few issues converting a MC to a bitmap. I have succeeded in loading a graphic from the library, loading that as a bitmap and I can use getPixel to get the color at a certain x,y point.BUT I have another part to the problem. I have a file upload where a user can upload an image and choose a color off that logo. So I have the logo uploading, then getting loaded into an MC on the stage and it all works honky dory.However, when I (thought) I was converting it to bitmap and then use getPixel, every part of it is just returning white.[code]But no matter what co-ordinates I put in, I always get white.

I've got a MovieClip which has bitmaps pasted onto it via AS3. These bitmaps are transformed and are sometimes over each others with transparency.So I would like to the grab the whole MovieClip as it is and make it a completely new bitmap. Problem is:
ActionScript Code:
bitmapData.draw(mc) //does NOT work in this case (nothing shows)
bitmapData.draw(mc.getChildAt(0)) // works, but it doesn't save the childs properties such as x,y coordinates and transparency
What I need is basicly a function such as "Image -> Apply Image" in photoshop.Except that it only copies a movieclip and not whole stage.
Is it possible convert 500 bitmap to movieclips at once or did i have convert all one by one.

View 1 RepliesOver the weekend i put together an MP3 player in Flex and just managed to figure out the SoundSpectrum.
It is working as expected.
I am facing problems when it comes to using a bitmap.
Right now, my "Analyser" class pulls the data from SoundMixer.computerSpectrum.
I then use that data with the drawing API to create a simple analyser. You know, just spikes.
Here is the code for that part:
Code:
private function update(e:TimerEvent): void
{
SoundMixer.computeSpectrum(ba, true);
var n:Number = 0;

Ok using common sense here, I am telling flash to take a snapshot of the Analyser and draw it to the bitmapData.
However, i cant seem to get this working. I am not using the dispose() method to clear the bitmap so id expect to see a mess of points (similar to if i removed the g.clear()) but nothing happens.
