ActionScript 2.0 :: Saving And Loading Bitmaps?
Jun 5, 2007
Ok I wrote an application where I have panels that the user can draw on, kind of like paint, but they can create panels. Now I want them to be able to save and load their work. Using Quasimondo's bitmap exporter, I was able to save a bitmap (200x200), and the application prompts the user where they were to save the image file. However, my problem is that the user will probably have 6-12 panels to save, and so I want the program to save all those panels so they can be loaded later.
Now in order to load, I don't want the user to manually select each panel to load. I want the user to select one file and it will load all the images into the panels. I was thinking about maybe loading a zip file and flash would extract the images and load them, but I don't know if that's possible. I think the user would need to select an XML file,which would direct Flash to what files to load and in what order. For this, and I'm assuming when it saves the flash application/php, it would need to write a new xml file.So I guess what I need to know how to do is:- How do I get flash to save several images to the server or the users hard drive- flash to generate an xml file- is there any way to make flash combine all the files into one file so that the user doesn't have to deal with several files?

I've been learning AS3 for a while now, and it's my first Actionscript language, but not my first coding language. I've learned a lot so far, but I started off doing things in the not so efficient, or correct ways. I was putting all of my actionscript on frames. I'm trying to get in the habit of doing it the right way now. But I'm having a basic problem. I can't figure out how to load a bitmap from the library in AS3.

To do this does it mean that I have to store them in another external location rather than my library and only load them when I need to use them from a URL request?

I want to load .jpg images into flash and store them as BitmapData objects. I've coded the loading of images many many times but I've never tried to store them as BitmapData, I just usually add the Loader to the display list and manipulate the image through its loader.
I feel like this is a very poor approach and so I want to try just saving BitmapData, because on the Model side of things thats really all I need.
Now the only way I have found to extract BitmapData from a loaded JPEG is to load the JPEG and upon completion write:
myBitmapData = Bitmap(loader.content).bitmapData;
First, is there a way to extract the BitmapData without encumbering the code with the Bitmap class? In other words, is there a way to extract that information without involving the Bitmap class - BitmapData while useful for a Bitmap is not dependent on Bitmap so ideally I would never involve Bitmap here.
Also, why is this Bitmap type-casting so widely accepted? loader.content is a DisplayObject and therefore is not necessarily compatible with Bitmap. Further, for all Flash knows we just loaded an SWF and as far as I know you can't typecast that to a Bitmap.

I'm trying to figure out the best way to compare a single bitmap against perhaps an array of saved bitmaps to see how close of a match it may be to any one of the bitmaps stored in the array. Right now I'm running a for loop that uses the bitmapData.compare() method to try to compare to see how much of a variance there is but... to be honest I'm at a loss as to how to use the resulting data to do so. Does anyone know of any good method to accomplish what I am trying to do? Forget looking at my code it's a waste of time because simply, it's not working.

I have 2 questions regarding bitmaps. Say I'm loaing graphics from a game off a server into a .swf file:
1) Which format is the best to use - gif, jpeg,png? (for non transparent images)
2) When a user plays a .swf movie it gets saved to their browser cache and its loaded the next time they access the same file, but when your externally loading images does flash have to re-download all the images or is it all stored in the browser cache?

I'm trying to setup a program that loads a set number of pictures (the exact number is stored in resources/data.txt). Pictures are labled picture# starting at 0 and increasing.
My problem is that I want to store the loaded pictures, which is giving me trouble. When I try to trace the bitArray length, it says it is zero..
My Code:
//Variable Initilizing
//Loaders:
var mLoader:URLLoader;[code]....

I have my .fla file and .swf file in a folder on my desktop
i want to add to that file a bitmap. everytime my flash project receives a the String "loadBITMAP" i want it to reload that bitmap into a designated area on the stage. (i am using a system of binary sockets to recieve data, but don't worry about that...i know how to process that already.) so basically my code will say
Code:
if(socket.readUTFBytes="loadBitmap"){
need code here on how to load bitmap

BTW, this should be in actionscript 3.
What's the fastest way to dump your data (not in a file) into a bitmap for display?
I had it working with setPixels and colored rects but that's way too slow.
Is there a way to load in the raw bytes or hijack the loader class to put in custom loader data?

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 ...

I have created a simple flash animation for my employer. I basically have a square that changes color depending on which of three buttons are clicked. This is replicated about 30 times on the page. There is also about 15 circles that have a toggle button created so that when you click on the circle, they change between two colors. As I said, a very simple application.
Now, I need to save the data so that whenever someone new opens the swf, the current color combination is displayed. My way of thinking, with my limited AS3 experience, is that each button click, in addition to changing the color of a movie clip, should also send the data to a server. Then when someone opens the application fresh, I can use the URLLoader to load the most current data.
Am I on the right track, or am I missing it completely? I think I can figure out the URLLoader, but what code would I use to create the text file or xml file?Here is a snippet of my code:
var rtmColor:ColorTransform = f13335.transform.colorTransform;
var okColor:ColorTransform = f13335.transform.colorTransform;
var usColor:ColorTransform = f13335.transform.colorTransform;
[code].....
By clicking on either the rtm_13335, ok_13335, or us_13335 buttons, they will change the f13335 movie clip to the appropriate color (blue, green, or red). The default color is green.
What I would like to do is make the movie clip red, for example, then another person opens the swf, and the movie clip is red as opposed to the default green because I saved the current state to a text or xml file.

hey people wondering if there is a way to use AS3 to save and load to a database.
Specifically I have created a flash program for a teacher that runs tests for her students. When a student loads up the .swf they are prompted for their name. Ideally we would like to be able to save the progress of a student after he/she has completed a test and then use that data later. Is there a way to save data like this and call upon it at a later time?

I've made a small application in Flash CS4 that I use when I'm teaching. Part of the application allows me to 'write' on draggable 'post-it' notes (using a draw function) and another part allows me to type text onto similar 'post-it' notes. how I could save the data that is written or typed in and then re-load it on another occasion? Am I out of my depth?My AS3 is probably intermediate level, I have some experience with SWF Studio and I'm beginner level with php/mySQL.

I've searched load of threads for info on this because for what I'm doing I need to save data to the local disk and then load it back up again as required. I'm using a local shared object to save data to and this works fine. Getting it back out again seems less straightforward.[code]Nothing appears to happen at all. The program continues with no traced output at all.

I'm trying to save a change to a text document (In this case a variable "Title" just to test) and then view the changes from another swf movie... In the end I'm hoping to build a client updatable flash site. In particular menu items... feature items & prices.
A Recap: a client types in the items, php/flash saves the changes to the text document, and site visitors can views those changes.
Something in my code isn't clicking:
My PHP is:
Code:
<?php
$Title = $_POST['Title'];
$toSave = "Title=".$Title;
[code]....

I have a project where the user uploads a large 300dpi image, then manipulates it (drag it, rotate it, position it). And the user can reuse this 300 dpi image, basically to make something like a t-shirt pattern. Then when the user is ready, they save this t-shirt pattern, and the save format is a large 300dpi png. This saved png file is for printing. Now I figure I can have PHP take bitmap data (as binary I assume) and the php can create the png. Is it a good idea to use Flash for this? I will have to scale down the users loaded 300dpi image so they can position. Then I assume scale it back up when it comes time to save Does anyone think Flash can't handle this?

the short version of what i need to do - via AS3 and PHP - is a user can come to this project and draw something. drawing's no problem, that's done. my issue is figuring out how to take that drawing data, converting it into something i can save to my database ... then reload said data and recreate it on the stage when the user "loads" it.
i guess i'm just searching for a way to take drawn data (just using typical as3 drawing methods) and breaking it down to a string, then bringing that string back in and recreating it. i'm not super versed in ByteArrays - which i suspect is where my answer lies.
user doesn't need to adjust any of this after it's loaded, fwiw. i'd just like to send this drawing data out - then bring it back in and place it back on the stage.

So I want to do saving and loading for variables. I.E. I want to save a variable by pressing the save button. When you use the "load" button, the variable is what it was when it was saved. I've tried this but it didn't work...
Code:
//Code on the frame
var saveState = SharedObject.getLocal("Cookie");
//Code on the save button
on (release) {
_root.save.gotoAndPlay(2);
savefile.data.blah = _root.blah;
savefile.flush();
}
//Code on the load button
on (release) {
gotoAndStop(3);
_root.blah = savefile.data.blah;
}

I know this can be done, but not sure how. I have seen a program that basically has its own fscommands and must compile them itself. Does anyone know how you would do this. The program i refer to is [URL] flash studio pro. There are other programs out there like this but these all cost money for commercial use.

I know the basics of shared objects but I never really got into it I was wondering if there is a way that I could save and load movieclips that I attach to the stage(Each has its own name such as clip_1,clip_2,etc) including the location(_x,_y,rot) and have it duplicate them all over again and move them to the same location as before (I'm using Actionscript 2, by the way)
