Flex :: Bitmapdata From Multiple Images (drag & Dropped)
May 29, 2011
I have an image loaded from BitmapData displayed in an Image control. This Image control has dragEnabled and user can drag and drop small images (from a bunch of images in a TileList) on top of it.
The image loaded from the Bitmapdata can be different every time with different resolution and the Image control scales it down to fit its fixed with/height. But while saving the image after editing I am saving it with its original width/height. For this purpose I am storing the original Bitmapdata in a temp object and applying any edits there before saving.
how to create an image combining the Large image and the small images dropped into it. May be I can use display object snapshot but then I want to save the image with its original with/height and preferably after converting it to Bitmapdata.

When I drop an image onto my canvas I can get the nativePath to the image but not the bitmapdata wich is the one I need.
In debug mode when I look into the file properties the data is set to NULL.
In my code file.data doesn't give me anything.
protected function creationCompleteHandler(event:FlexEvent):void
{
this.addEventListener(NativeDragEvent.NATIVE_DRAG_ENTER,onDragIn);

Just trying to add a little more functionality to this code for a drag and drop interaction. Suppose I have multiple objects to drag and some will have the same target. Right now (with this code), the draggable object gets positioned in the center of it's target so my draggalbe movieclips will overlap eachother once they're dropped on the correct target.
What I'd like to do is prevent this overlapping and have the movieclips slightly offset on the y axis so they cascade a bit. Could do this by writing out alot of code for the individual movieclips but i'd like to condense it a bit.
Code:
function dragSetup(clip, targ) {
clip.onPress = function() {
startDrag(this);

Simple drag and drop application where mc is dragged out of one parent mc and dropped into another parent mc.All works OK until I added 2 text boxes to the mc's -- one is a non-selectable dynamic text box (a label) which is set by the code, the other is selectable input text that the user can amend.
Finger cursor disappears when user hovers over the section of the mc that contains the text fields (even non-selectable text??) When the user trys to drag the mc by inadvertantly click-dragging anywhere within both text areas it causes this error: TypeError: Error #1034: Type Coercion failed: cannot convert flash.text::TextField@2374a381 to flash.display. MovieClip (same error appears for both text boxes)
The input text box may confuse the user - how do they sometimes click to drag and sometimes click to amend? I need to create an overlay area within the mc that is click-detected for the drag? Here's the relevant bits of code:
var itemArray:Array = [
{iname:"police",ititle:"POLICE OFFICER"},
{iname:"insurance_assessor",ititle:"INSURANCE ASSESSOR"},[code].............

I have an image loaded from an url and added to canvas as child. Then I am drag and dropping another image on it which also uses the senocular transform so the image can be transformed on the canvas. I have coded in such way that the transform handles shows up only after it's dropped on canvas. The image shows up correctly. But I am trying to save the result image (that is the main image and the dropped image on top of it), I only end up with the main image that was loaded earlier. The dropped image doesn't show up.
Below is the code for handleDrop() that is fired on dragDrop event and prepares the final image.

So I made a drag and drop app where I can drop in an image, it get's resized and saved automatically on the desktop.
But now I want to do the same when there are multiple images dragged in. This is where I'm stuck...
private function onDrop(e:NativeDragEvent):void
{
trace("Dropped!");
var dropfiles:Array = e.clipboard.getData(ClipboardFormats.FILE_LIST_FORMAT) as Array;
[Code]....
The problem is that I want the completeHandler() to run after every ldr.load() but in my code it only runs once right after the for each loop.

I'm Trying to develop a small game where the user chooses from a range of boxes of the left of screen and can drag 3 of them separatley to 3 holding boxes on ther right. each box can be dragged to any location and the order is not important. Once the 3 holding boxes are all full I want a new button to appear. I completed a tutorial and I've got one box working perfectly but no matter what i try I can't get it working with multiple boxes and locations. Below is a list of the instance names of the movie clips plus my actionscript. I've attached a link to the flash file.
[URL]
INSTANCE NAMES
box 1 = "circle_mc"
box 2 = "circle_mc2"
both the grey boxes are called = "targetCircle"

im creating a small drag and drop game in AS3-
I have 4 objects and 4 targets,
I want to be able to drag any of the 4 objects onto any of the targets, right now all I can manage is to allow each object drop onto one specific target only.
I thought by calling all my target names by the same instance name eg target_mc that would work but only one target will ever work.

I'm making a Multiple Drag and Drop in Multiple Targets educational puzzle for 6-7 y/o kids that tries to teach them a bit about which plants grow in which environments in the country. So, I have a map of Mexico divided in 3 diferent zones: desert, forest and tropic, and 6 different plants (of 3 different groups: cacti, pines and tropical flowers, 2 of each) scattered across the stage and around the map. The goal is for the kids to drop the plants in the right zone and then to click a "verify" button that triggers a validation process. Each of the plant's movie clip has 2 frames with a stop(); action on each: the plant graphic spans across both frames and the second frame has a red error sign over the graphic that indicates an error has occured (if that's the case). Then the validation process triggered by the "verify" button is supposed to move the playhead of each wrongly placed plant move clip to the second frame to show which plants are misplaced and move the main timeline's playhead to a frame that contains a "Please try again" text and a "Restart Puzzle" button. If all the answers are right, an animation plays saying that it was VERY WELL DONE! .
I searched the internet for some tutorials and found a file that is pretty close to what I need. I've tried to adapt the code to my puzzle but have failed miserably. The file is here if you want to check it out (scroll to the bottom of the page, it's called Soldier.fla). I'm not pasting the code here because it's VERY long, but I will if required. If you want me to upload the files somewhere else and link them here, I will. If you need me to send them to you I'll be glad.

I'm scaling down images loaded from as3 and I want them to stay sharp. They are scaled because I have a liquid layout which resizes a "body" movieclip that contains the images (loaded from xml).
I used code from here to scale bitmap, but I don't really understand it. [URL]
My biggest problem is that since the images are loaded as displayObjects rather than bitmaps, I need to know how to change the bitmapData of each displayObject.
Second problem is that I need the code the change the data, but not scale it down also(it is already scaled down). How do I do that?
Here is my attempt...
Code:
//code is executed when image is first loaded (I don't care if it is resized afterwards)
//thumb is the displayObject that is my image

I am creating an interactive post-it for an upcoming event that allows for us to tap into a sql database and post tweets, survey answers and images. We've already tapped into the Twitter API and the survey, so those are A-OK.The problem lies within loading the images from a location other than the local interactive board's server.If the image itself is locally hosted, it loads just fine.If the image is hosted elsewhere, the image will not load, even though I have a trace on the URL of said image.I'm loading all tweets, surveys and images through an XML load and all the data is loading properly.I AM loading the image through a smoothing filter so that when the "post-its" are slightly rotated, they are not jagged. Here is THAT code:[code]
This is a two part script where the bulk loads in the image and places it into an empty movieclip, then adds the smoothing filter. The second part is a resizer that automatically resizes the image and keeps the aspect ratio.When I test the flash piece (not embedded in HTML) the thing works 100%.As soon as I put the swf into an html and view it on a web page, the remote images will not load.I'm a bit stumped on why this is, could this be a firewall or security issue? Because I work in a high security firewall environment.

As my as3 skills are not good, I stumbled against this problem, my approach in overall will probably not be the easiest, but here it goes:
In the library of my fla file I have imported 4 pictures, in the properties (class) I gave them the name photo0, photo1, photo2, photo3. With my code on the time line I create dynamically 4 movieclips and now I want to attach photo0 to movieclip 1 and photo 2 to movieclip 2 and sofort...
Is there a way to give the bitmapdata name also a dynamic name, something like[code]...

When you load an image into a MovieClip then use that as the data source to draw() into a BitmapData object, the documentation says "Optionally, you can specify whether the bitmap should be smoothed when scaled. This works only if the source object is a BitmapData object." To me that implies that a second BitmapData object is needed in order for the optional [smooth:Boolean] parameter to work when set to true.
We found we didn't need to "double buffer" in this way when using MovieClip.attachBitmap() with the [smoothing:Boolean] parameter set to true. We did run into another problem though. This problem only manifests itself when you run the SWF as part of an HTML file running from a local web server like http://127.0.0.1. Here's the problem: images are loaded dynamically (URL's pulled from assets.xml) and the ones that are loaded locally from a directory on the same machine load and are smooth and distortion free. Other URL's point to a remote host. The images loaded via a remote source (example) do not "smooth nicely" running the exact same code as the local images. The remote images are shimmery and exhibit update artifacts. If you run the exact same page not via an http:// web sever i.e. - just loading the html page into the IE, then the remote images do get nice smoothing when animated.
Is there some magic to get BitmapData loaded from a remote source to smooth correctly when run from a local web sever? For our internal demo we removed any remote URLs so we could demonstrate that Flash does provide the ability for nice smooth animations but it would be a good problem to solve.

I have a question about optimum resource management. So I am pondering what would be the most efficient way of storing a LARGE number of BitmapData instances in a SWF. The BitmapDatas would be generated at runtime. Only a minority of the BitmapData instances would be on screen at any one time. So far I've conceived three routes; Option one (simply store them in an array - this is then stored in the RAM right?)
ActionScript Code:
var array:Array = new Array();
var bitmapData1:BitmapData = new Bitmapdata();
var bitmapData2:BitmapData = new Bitmapdata();
array.push(bitmapData1);
array.push(bitmapData2);

is there anything that will take a very large png (even larger then the total pixel limit of BitmapData) and load in the png as raw bytes into a bytearray and then take that array and grab only portions of the image to be able to generate a grid of usable bitmaps to render the very large png..I got to the point where I was able to get the png as a bytearray but from there I don't know how to grab a portion of the bytearray and attempt to load the partial bytes in a loader via loadBytes()..basically I think I need a decoder to decode the partial bytes to a bitmapdata.

I am trying to let the user import giant images into a flash application. Unfortunately the BitmapData object's dimensions cannot exceed "8,191 pixels in width or height, and the total number of pixels cannot exceed 16,777,215 pixels" (see Reference)
Obviously with FlashPlayer11 these limitations vanish - BUT: As I only get bytes from the FileReference, I need to convert these via Loader.loadBytes(), to get access to the image data. This doesn't seem to work for images exceeding the old BitmapData limitations.

I am creating a program that is effectively an sprite creator. I'm very new to AS3, but I know JQuery, JS, PHP, etc. After going through multiple steps of selecting pieces to customize a character, you are supposed to be able to download the final product using fileReference(). Everything works, and I can download the image in the end, but the problem is that I cannot capture all of several movieclips on the stage, I can only capture one. Maybe this will help clarify:
[Code]...
Could it be that each of the movieclips I'm adding to the sprite have children of their own?
