ActionScript 3.0 :: How To Manage Large External Images
Dec 6, 2008
I'm creating a movie object using images. I'm using PNG file types with an alpha channel. Each frame is approx 640 x 480, each single pitch image is 36 frames creating an image 23040 x 480. If it's a multidimensional image it is 23040 x 11520. I load the image in using "img_name".loadMovie("imageFileName", 1);
The problem is it only seems to load around 2880 pix of the image.
How can I get it to load the whole image? How can I choose it to load the next section of the image?

Part of a larger presentation I've made, there is some background music. What happens is an XML file is read to get a file to play. It plays. When it finishes, it reads the XML again to get the new file. It can also stop when a video plays elsewhere in the presentation then I pick it up where it left off and start the process again. Trouble is, the presentation randomly stops. The music stops and the slides in the presentation stop. The music and slides come from a single XML file. There's also a third part of the presentation (a text crawler) that never stops.
This comes from a totally separate XML file. I never get an error, the presentation just stops on a slide and no more music plays, but the crawler keeps crawling. I've removed all the code for the music and it runs perfectly so it's obviously related to how the music is managed. So, finally, my question is how do I manage sound objects? If I need to create new objects for each sound I load and play, I'll need to do manage the sound from a single function, right? Something like:
Code:
function whatever():void {
if song is not loaded {
read xml, load and play song;
} else if video is playing {
pause the song;
} else if video has stopped playing {
resume song;
}}

loading large images(12000x6000). there are a number of interesting workarounds, but all a a bit clunky.
this is for a local application - not internet.

I'm new in the flash world. I'm trying to set up my website but I keep on getting errors! I manage to create a loader to load the images of my portfolio, first I couldn't remove the previous image, when I loaded the second one, the first one was still there. Now it seems to disappear when I added the line removeChild(loader1). BUT I still get a message in the output panel:
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller. at flash.display::DisplayObjectContainer/removeChild() at prueba3_fla::MainTimeline/clickF2()
I don't know if this is going to be a problem in the future or not. I don't have any idea of what this message is talking about

I wrot a FLA in AS3 which is basicaly a nicly designed Loader which loads little cute SWF games. Each game is built a bit differently and has its own 'thing'.I was wondering, how can I control the sound of the SWF's from the Loader File?
Which leads me to a wider issue of how can I control variables of a loaded SWF.

I have 2 AIR applications (A and B) that are able to communicate via a LocalConnection object. I've verified that messages are definitely being sent/received appropriately.
I want to be able to have A tell B to come to the front. Both applications are full screen:
stage.fullScreenSourceRect = new Rectangle(0, 0, 1080, 1920);
stage.displayState = StageDisplayState.FULL_SCREEN_INTERACTIVE;
I've tried several permutations, but as of yet nothing seems to work.
private function initSlave(channel: String): void {
conn = new LocalConnection();
conn.client = {
[Code]...
If I leave both applications in windowed mode (stage.displayState = StageDisplayState.NORMAL), then toggling alwaysInFront actually works. Calling activate() or orderToFront() still do nothing. If I try to toggle alwaysInFront and then set the application to fullscreen, the application ends up fullscreen behind my windowed app. Maybe there is an event I should wait for before setting the app to fullscreen?
I found a thread mentioning that orderToFront() only works relative to windows within the same application, which explains why it doesn't seem to do anything.
Does anyone have any insights into pulling this off? Maybe there is a way for me to embed B into application A so they are actually the same application? I am not sure how to do this with an AIR application as simply as just loading the SWF due to requiring external resources.

I use Flash primarily for animation. The project I'm working on currently is a hefty 1920 X 1080 square pixel file and currently weighs in at 187mb because of all the sounds and jpg images.It's 2 minutes long.
The problem occuring is new to me as I've never worked with projects this long or in this resolution. Or with this much data (sound effects, jpgs, etc).
The problem is this: I'm trying to import a high resolution photograph (3500x2500) onto the stage or even just in the library. I'm using the photos to get an idea on where the final animation will be placed (photo backgrounds, flash animation, composited in After Effects, think Roger Rabbit).

I found this bug in Flash 8, so I just downloaded CS5.5 trial and I see the same problem. When I increase the image export resolution to get a larger image, at one point the lower section of the image became white (the image has the appropriate size but the content is not rendered in the lower section). As bigger is the image, larger is the white fraction. The amount of useful pixels always stay around 10 or 13 megapixels. Here some examples:Original image was 3375x6710 pixels in the left one and 2625x5219 en the right one.

I'm getting crazy with this error and found no solution until now. Well, the issue consist in create dynamic movieclips and external jpgs into a for loop through xml nodes and add the respective image into that movieclip.

I'm having an issue where when I try to print a larger image via printjob one of two things happens. One either the job fails or two the output of the image is literally diagonally cut off. I am simply passing the stage to the print job. I've tried both with and without using printAsBitmap.

I have this code which works fine when selecting a small number of images.
public var fileReferenceList:FileReferenceList;
public function browseFiles(event:Event = null):void
{
[Code]....
However, when selecting a large number of images (1000+), the fileList isn't initialized yet when the SELECT event is dispatched. Is there a way to wait for the fileList to be initialized?

I have some pretty large PNG images stored in a database (example 1000x15000 px, 4.5MB). I am trying to load this using the Loader class...the problem I am having is when I call load(), nothing happens. No events, no errors.I can take the same image and embed it. As long as as I set the height to less than 8000px it works fine. If I convert the embedded image to a ByteArray and try to load it, nothing happens.

Here is an example online, I am trying something similar but am not happy with what I am seeing, perhaps it is just on my side. The scrolling seems choppy/jagged. I have this same issue doing a similar scroll with lots of big images. Is there any way to get a nice smooth scroll at a decent speed with flash?
Ive ported my as2 code into as3 but am seeing the same results. I have used tweener and tweenlite, nothing Ive tried is helping. how to achieve a smooth scroll?

I'm building a flash based site for my photography in Flash CS3 with actionscript 2. The swf is almost 700kb so I guess I'll need a preloader right? I thought I could create a preloader scene before the main content scene and apply the following code to the single frame within the preloader:
Code:
ifFrameLoaded ("website", 3){
gotoAndPlay ("website", 1);
}
This doesn't seem to work as the large images in my gallery (contained within a movie clip) won't load unless you leave the gallery page then go back in?

I am attempting to capture a very large image that was made dynamically within the Flash Player (the size of the image is 2400px by 12,000px) and am running into some very serious issues... Let me run down how the image get's to that size in the first place:
User adds elements to a canvas and then when the user is finished the canvas scales up to 2400px wide and ~12,000px tall. The problem arises when I attempt to save the image to the hard drive. Now, I dont know if this will affect the recommended fix, but the rendered image wont be saved on the hard drive, it will be sent to a server. I know about the ~4050px limit in Flash Player and was thinking I could get around that by clipping the images with the ImageSnapshot.captureBitmapData() method and keeping the required Rectangle variable below 4000px then repeat that down the large image until it reaches the end where the final images will be pieced together at a later time. However... As i mentioned the error comes when it reaches the 'fileReference.save(pngImage);' method..

I am creating an image gallery and it has a set of scrolling thumbs at the bottom and when clicked it opens an image that is the large version of it. What i would like to do is have the scrolling thumbs inside a black stroked box using the drawing API and when clicked it opens that image larger with another black box around that image. I know you have to use the drawing API but I have no idea on how to implement it at all. Also is there any chance each image could have a preloader on it.[code]...

I've recently picked up some flash work after a long respite into motion graphics via after effects, and I'm slowly mucking my way through things. I've currently got more than 250k pixels I need to seamlessly scroll through horizontally, via a scrollbar and buttons. I've bitten off more than I expected! I've been searching around, and it seems like tile based scrolling is what I'm going to need, due to max bitmap restrictions, is this correct?
If I'm on the right track here, I throw myself on the mercy of the community for any tile-based scrolling resources out there that you know of, something that explains the idea and setup from a non-game point of view maybe? Sorry if I seem like another noob looking for a quick fix, I've honestly been trying to find info on this all morning. Also, feel free to smack me into shape if I'm making this harder on myself than necessary.

I have an all flash website that works by having each portion of it to load and unload in the center of a frame based off the navigation chosen.Load times on everything but one part of my site are ok.The dimensions of the part inside the frame are 968x674.I know that's relatively large for a flash file, but that can't be changed at this point.Within the page there are objects that come up when you find an item on the screen.Its a dialog box and it shows text, an image, and has a voice over that reads what the text says.After you're done looking at it, there is an x-button to dismiss the window.There are 15 of these and they are exported to the actionscript.I add them in the actionscript via addChild.
The other huge thing is there is a ton on the screen.It starts you off in an environment, and when you click 3 different sections, it zooms into that portion allowing you to look for the items you're trying to find.There is also a man that talks and animates in the beginning and at the end.We are planning on taking out the end part and putting a text box up. URL...The two parts of the site we are trying to optimize is the main menu when you first are at the site, and the "Explore" section.(Just click on the cloud on the front page.

I am creating a Flash site for a client who wants to display many (about 15) fairly hi-res photos as well as a video. I am using the Video class to display and control the video, and the Loader class to load the photos. I preload them from an XML file up front, while "loading..." is displayed.
The video plays immediately after the loader finishes, and the user can also choose to view the slideshow, which has left/right arrows which show each photo with a simple fade tween between each one.
The problem I am having seems to be that when all these assets are loaded, the video and the "fade" effects are very choppy. If I cut down on the number of photos, everything works fine; but I have to include all of them, plus the video.
I am storing all the Loader instances in an array, and when they are requested, I add them to the stage and fade them in. When it finishes fading in I remove the previous one from the stage. So they are all stored in Flash's "memory", but there is only one Loader or Video instance on the stage at any given time. Is there a better way to handle this? Perhaps some way to cache the images but not bog down Flash's memory? I would prefer to have everything loaded up front in order to avoid needing a "loading..." for every slide.

We build prototypes and demo applications in Flex 4.5.1 and AIR 2.7 for mobile and desktop use. These tend to involve a large number of full-screen .PNG files. Lately we have been looking at ways to segment our code for flexibility and multi-screen re-use. What suggestions do people have for segmenting the project and libraries such that compile times are minimal and images are easy to replace?

I have a photo gallery that is XML based. In IE everything works fine. In Firefox, the gallery will load all the thumbnails and then hang up when loading the large image. The trouble is this only happens on the galleries that have a lot of images in them. It works fine with smaller galleries. Since it's xml driven, the images are not loaded until called for and all the thumbnails get loaded. I did see a post about a var being collected for garbage if it's defined inside a function, but I've tried to limit that to just declaring a new image to be displayed. My site is: [URL]. If for some reason you get a page saying that this site is under construction, click the link to the gallery again. I don't know why that keeps bringing up an old page.

I am building a portfolio site which dynamically loads large hi-res images when the user clicks on a thumnail. However I'm having problems maintaining the original image's quality when resizing it to fit the current browser. Currently I'm just adjusting the width & height properties of the image to width to the stage proportionally which is working fine getting it to fit, however I cannot figure out how to maintain image quality? Do I need to load it as a bitmap and redraw/smooth or something similar?[code]

I am trying to build an xml photo gallery in flash that will use lightbox for viewing large images. I have successfully built the thumbnail portion.My goal is to insert the swf into an HTML page and launch lightbox from the swf. Here is the code: First I use a Thumbnails class which imports the tweener class
Code:
package {
import flash.display.Sprite;
import fl.containers.UILoader;[code]....
how do I get lightbox to work when I click on the thumbnails? I found this thing called lightboxinjector that seems like it would work, but I am not advanced enough to understand the directions it gives for dynamic use. Or is there a lightbox clone that will work for this?

I'm running into a brick wall here. My dictionary.txt file, which is loaded into ActionScript and shoved into an array, cannot be uploaded by the licensing company to license my game. However, I wrote a program to convert the space-delimited text file into an .as file, looking like so:[code]Thing is, now the .as is 3MB in size, and all ActionScript in the game fails to load.So I either need two things:
- Some way to embed the .txt file within the .swf
- Some way to make the .as file load without issues.

Im making a flash project in flash cs3 using As2.It is a large interactive game with imported external swfs throughout,Ive placed the lockroot code in all the external swfs.
When i play the external swfs on their own they play perfectly put when imported into the main.fla they don't work properly,some of the functionality doesnt work properly..As an example I have made a jigsaw game using drag n drop and targets, where the code
if(this._droptarget == "/dropTargetOne")
{
_root.dragger1.gotoAndStop("5");}
}
appears I have problems because the code _root.dragger1.gotoAndStop("5"); doesnt work when imported as an external swf.I've tried using this._parent but no success.So I think the problem is to do with using _root which I was hoping would be sorted with this._lockroot = true;
