Actionscript 3 :: Flex - Get The Bitmap Data From A Component
Jan 18, 2010
Is it possible to get the bitmap data from a component using ActionScript? I dynamically load an image. onComplete I create a Flex Image component and add the loaded image to the source
[Code]...
Later I want to create a new Image component and get the bitmapData from the first Image. I have tried this canvas.getChildAt(0) Which seems to give me the Image, but I can not figure out how to get the bitmap data. canvas.getChildAt(0).bitmapData; gives me a compile error "... undefined property" how ot get the bitmap data so I can use it in my new Image component?

I am trying to take images I am placing in a flex canvas component to a bitmap. I was able to get to the point where I'm not getting an error but then no image shows up and the image I save out as a jpg is blank. I imagine I'm not setting the bitmap data correctly but can't figure out what I am doing wrong.
Here is the code where I am converting it to a bitmap:

I'm cutting my teeth in actionscript 3 on a game that has a character running through a world. So, I have set up my Hit Testing by using the bitmap data hit test method, since I figured my world is going to be destructible - it'd be nice to update the level and then redraw it and have the character interact with the new change. (That works beautifully) I am however; a bit confused as to how I have my hit Testing set up. I've been messing around with it, and it works for now - but I'm not sure why.. currently, I have a character set up by using a class I built and using a series of animations I created. So, this character has a walking and falling animation, etc. This is a movie clip.
Then there's a bitmap 'emptyBitmap' with bitmap data created - however; I never really added this as a child to the character. This is sized to the dimensions of my character. My level is created as a movielip, then it's drawn to a bitmap - when the level movieclip is changed, the bitmap redraws, and that's how this updates.

I'm using Flex with Cairngorm framework.I have a custom component which I create like this:
<components:FriendSearchPaginator id="searchResultsPaginator"
paginationElement="{_model.findFriendsPaginationElement}"
visible="{_model.friendsSearchResultsPaginatorVisible}" />
Where the findFriendsPaginationElement is inside the model locator:
public var
[Bindable]
findFriendsPaginationElement:PaginationElement = new PaginationElement();
Inside the custom component I have button that uses a property of findFriendsPaginationElement object:
<s:Button id="previousButton"
label=" prev "
click="paginateSearchResults(false)"
enabled="{_model.findFriendsPaginationElement.more_previous}"/>
But I get a warning from Flex that the binding wouldn't work that way and it doesn't. It works the first time I load up the component but every time I change findFriendsPaginationElement it doesn't reflect on the component. Do you know how I can go about doing this? (making changing a value in the binding variable changes the status of an element inside a component?)

I have a DataGrid component that I would like to update every 5 seconds. As rows are being added to this DataGrid I noticed that every update causes it to reset the scroll bar position to the top. How can I manage to keep the scroll bar at its previous position?

I have a main mxml file (flex4) and want to pass a parameter (user_name) to a component in a directory called components. When I run the program, the user_name is NOT being sent from the main to the component file. (Interestingly, if you make the component visible, you can see the parameter has been passed).
I have hacked much larger files down to get the following two files:
Main
<?xml version="1.0" encoding="utf-8"?>
<s:Application
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"

I'm trying to propagate an assignment to the data parameter of a sub-component through it's parent component's setter. Like this:
<CustomComponent
xmlns:mx="http://www.adobe.com/2006/mxml"
xmlns="components.*"
[Code].....
When I ran my application, the sub-component never received its data. When debugging and stepping to the line marked "ref #1", the debugger jumps out of the method and continues on to something else as if the method was complete. It seems like some exception or error was thrown but the console gives no indication of what is wrong with this assignment.
Environment: This is using Flex SDK 3.2, with the Flex Builder 3 plugin for Eclipse on Windows, with Flash 9 Debug ver. for IE7.
Note: With this particular example I'm trying to avoid Binding on purpose. I mean, why can't I manually push the data to the sub-component rather than binding it?

I am looking for a fairly simple image comparison method in AS3. I have taken an image from a web cam (with no subject) passed it in to bitmap data, then a second image is taken (this time with a subject) to compare this data, from these two images I would like to create a mask from the pixels that match on both bitmaps. I have been scratching my head for a while, and I am not really making any progress. Could any one point me in the right direction for pixel comparison method, something like getPixel32()

Is there a way to export Table data to a MIME Resource(Flex3 component) from Web Dynpro?
I have a flex3 component(US heat Map) which accepts a arrayCollection (state and value pairs). I need to create a webdynpro wrapper for this to use in Visual Composer 7.2.
What I am trying to do is migrate the flex components I made for Visual Composer 7.0 (using a VCXL wrapper) to Visual Composer 7.2 using web Dynpro. I have managed to migrate components which require simple input data types like integer or string, but I am stuck at those which require complex structures like an array collection.

I have a component where I expose the property 'questions' with the following code:
private var _questions:ArrayCollection;
private var questionsChanged:Boolean;
[Bindable("questionsChanged")]
[Code]....
In this component, I use commitProperties() to implement my logic.
I use Cairngorm and the 'questions' is in the model and hence it's defined as a source for data binding.
When the 'questions' ArrayCollection's size changes elsewhere in the application, it is not invoking the setter method in the component that is destination for the data binding.

I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?

I'm working on a Flash game and I'm using button components in the UI. I like that the key functionality is built into them and that they are fairly easy to skin. The problem is, I need to be able to skin them with a bitmap (specifically a PNG) using AS3. I've found a couple of Flex frameworks out there that might help but we're not using Flex in our development process.

I'm using the XML Connector to bind information to a List Component. Everything binds okay but when I run the MC I only get one item of information. The object I'm binding from the XML is called "Location" and there are a total of 5 listed in the XML. The five are Los Angeles, Seattle... The only one being displayed is Los Angeles. What do I need to do get the other 4 locations to display in the list?

I've created a prototype that will copy the pixel data from a movie clip then create a JPG image from it via PHP. It works perfectly. But when the MovieClip (called mcImage) contains a Video Object loaded with a streamed FLV, it won't copy the pixel data to the Bitmap object. The image generated is white. Here's a sample code:
var oBitmap:BitmapData = new BitmapData(nW, nH, true);
var oMatrix = new Matrix();
var oColorTrans:ColorTransform = new ColorTransform();
