ActionScript 3.0 :: Image Loader To Bitmap
Apr 10, 2012
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.

I set up this sample movie clip in the hopes to figure out a problem I'm having:[code]In the above code, I can add the contents of myImageLoader to myMovieClip with no issues and it resizes as expected (and consequently artifacts appear). With the final two lines of code, apparently myBitmap is not being loaded with the contents of myImageLoader.content which will cause the final line to fail with the following error:Code:TypeError: Error #1009: Cannot access a property or method of a null object reference.at loadImageTest_fla::Main Timeline/frame1()I understand the error, I just don't get why the contents are not being loaded into the bitmap object.

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.
Code:
import caurina.transitions.Tweener;
var btn:Object;
var disabledBtn:Object;

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.

im working on an image viewer and im loading an image to a loader and then add the loader to the stage.I want the user to be able to drag and drop the image but since it's a loader i dont know how to do it.
I tried

imageLoader.content.startDrag = true;
but im getting an error on both.

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 was trying to build a class that would load external bitmap images into Bitmap objects. I'm having a bit of trouble as the image loads, but does not display visually. Heres the code to instantiate it:

ImageLoad.loadImage( loadd, '../ght.png' );
this.addChild(loadd);

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 want to load an external image (dest) and display it on the stage, and i want to load another image (src) which will not be visible. When i hold the left mouse button on the image that appears on the stage, then a function that start copies the src image to the dest will be invoked. Actually i want to reproduce the scratch effect on an image that hides another underneath. here is my code [ the copypixels function is triggered on mouse_move event for debug purposes ]
package
{
import flash.display.Sprite;
import flash.display.BitmapData;
[Code]....
Although the two images are loaded into memory and the first one is shown on the stage, when the mouse_move events triggers the corresponding handlers the copy does not work.

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.

I'm developing an app that currently is using Loader to get images from another server.This shouldn't currently work since we are still waiting for the owner of that server to put a crossdomain file in place.However, it does work -- sort of .
Loader can load the images fine, without an error.But then the app has a feature in which we are making a larger duplicate of the image to display in a sidebar, we do this in this manner:
var myBitmap:Bitmap = Bitmap(loader.content);
and when this runs we get a Flash player security error 2122, sandbox violation.So while I'm hoping all this will fix itself when the crossdomain.xml file is put in place,I'm confused as to why we only get the sandbox error when we make a Bitmap from the image, and not when we initially try to retrieve the image.
(Incidentally: is there a better way to make a "copy" of an image loaded by a Loader, and then change its width and height for simultaneous display in another part of the stage? I don't need to change its actual dimensions -- I just need to change its display width and height.)

I'm writing a class where I load a image with Loader and then tries to copy it into a Bitmap. This goes all and well when I do this in an event but not when I try to make a function of it.
Some code.....
class variables :
var imgLoader:Loader;
From Main :
imgLoader = new Loader();
[code].....
So far so good. but when I try to make a function that returns a copy of the previous loaded image (imgLoader) I get the error :
1067: Implicit coercion of a value of type flash.display:displayObject to an unrelated type flash.display:BitmapData.
The code looks in the function looks like this :
var bm:Bitmap = new Bitmap(imgLoader.content);
var bmret:Bitmap = new Bitmap(bm.bitmapData.clone());
Why is this? All I can think off is that in the LOAD COMPLETE event i get a reference of the current target (I think this is the way it works), and are not using the class variable defined at the top in the code.

I have this piece of code to change images. I was trying to figure out how you could put a timer on the code, so if the image has been displayed for say 5 seconds it diverts to the next image automatically? Also if it's not to hard, when it has played to the end to divert to the 1st image.

[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 looked through a couple threads here about reflecting images... but I don't quite understand it. I will include a link to my project thus far: Final Project First of all, ignore the music/mp3 items at the bottom of the stage. Those aren't wired up yet. When you click on a bike image on the right, the reflection image should appear under the image... but it's not quite working out that way, and I've tried a few things. Here's the segment of AS3 code that is giving me trouble:

Okay, I know this is a stupid question but, if you bring in a jpg or png image and either convert it to a graphic or a movie clip, or just leave it as an image, is there a way to distort the image other than scaling, rotating and skewing it. For example, I want to change the perspective of an image the way I do in photoshop.Let's say the image is a house, in photoshop, you can take the house and make it look like a trapezoid shape, you know, wider at the bottom than at the top Is there a way to do this using flash tools? Envelope distorting, if you break the image apart doesn't really work.

The basic concept: I want to at runtime overlay (or paste or whatever) one bitmap image asset onto another. The original image asset is a texture on a 3d sphere.Example:3D Sphere with earth texture applied to it. Put a cloud on the earth texture and have cloud move along the earth.
Caveats:Can't use any composite materials because I take a serious perf hit. Want to try working only with bitmaps to see if it is faster.I've gotten this far but don't know how to fill rectangle with jpeg file and certainly have no idea where to go from here..earthBitmap= new BitmapData( 256, 256, true); fillRect will only do a color ... I need what fills a rect with jpeg image and how to edit a bitmap on the fly.

Code:
stop();
