ActionScript 3.0 :: Extracting The Alpha And Color Channels From A Png To Create A Two Separate Images?
Jun 6, 2011
I'm trying to take a png and create two images, one that represents the color data and the other a grayscale version of the alpha channel.
Extracting the correct data was no problem, i'm just embedding the png, creating a new instance (as a Bitmap) and then extracting the relevent channels of it's bitmapData to two new bitmapData instances.
ActionScript Code:
[Embed(source='/../deploy/images/alpha_test.png')]
public var image : Class;
[code]....
The problem that i'm having, is that when i assign the colors bitmapData to a bitmap instance to display it, the background color is showing as black, even though the default fillColor of a bitmapData instance is white. how i can use the alpha channel data to create an 8 bit, grayscale image, that's the reverse of the channel?

What is the best way to merge two alpha channels? What I want to do is, given channel values, use the value which is greater.
I tried using .merge(), but it appears to only blend channels with a linear value between current and destination value.
I looked into .draw(), which would work well using a blendmode like LIGHTEN, but it doesn't allow drawing per channel so I can't target the alpha channel only. The ALPHA blendmode didn't seem to do anything when used with .draw(), and ERASE gives an unwanted hard edge.
I also looked into .copyChannel(), but it doesn't allow any blending logic, merely copying a rectangular region from one BitmapData to another.

what is it called when you have a image say 50x500 but is shown as a 50x50 and every so many seconds it changes its x by +50 making it play like a filmstrip. Also is it possible to color-to-alpha images imported VIA .load ?

i have the following situation:
one drawing layer (graphics object with lineTo, etc.)
one png with an alpha channel (supposed to serve only as a mask)
now i want to be able to only draw lines within an area restricted by the png mask.
i am trying like this:
var bitmapData:BitmapData = new BitmapData( 320, 320 );
bitmapData.draw( drawingLayer );
bitmapData.copyChannel( maskBitmapData, new Rectangle( 0, 0, 320, 320 ), new Point( 0, 0 ), BitmapDataChannel.ALPHA, BitmapDataChannel.ALPHA );
now the borders get cut off fine, but i get a black background, since the drawing layer has an alpha between the drawn lines (and it should remain like this) and the mask bitmap has an alpha outside the shape. so naturally the mask's alpha replaces the drawing layer's.
i tried it with merge, copyPixels and also with just setting the mask property on the drawing layer (i set everything to cacheAsBitmap) but to no avail.
ADDITION:
when trying to use a mask i tried it with
<s:BitmapImage id="mask" source="@Embed(source='...')" cacheAsBitmap="true" />
and also as
[Embed("...")]
private const BodyMask:Class;
var maskBitmap:Bitmap = new BodyMask();
and assigned them to the mask property of a s:Group element (cacheAsBitmap=true) where the operations on the graphics object occured. i also tried reassigning the mask after each draw operation.

I copied this from some other forum because it's explain well "...Let�s say you are loading in an external asset that has an alpha channel, such as a PNG. Now let�s say that you want that asset to act like a button, with rollover and click actions. No problem. No reason you can't do that. But, actually, there is a problem. The hit area for that external asset will be its entire bounding box. Take this octy image for example: Even if you rolled over the top left of the image where it�s totally transparent, it will still trigger rollover actions, which is certainly not ideal and could potentially be very confusing for a user..."

I I have an alpha-numeric string as a variable. I would like to extract (from left to right) all of the numbers from the string and then push them into an array. Below, is what I have going so far, but it stops after the first number it meets. I was under the impression that the RegExp.exec runs through the entire string before stopping.
var testMenu:RegExp = /d/;
var whichTarget:String = me.target.name[code]..........
when I trace my array, it is just filled with the first number that is encountered. So, in the two examples above the array beomes [1] (when the string that is executed is "menu1sub2hypo3" and then [3] when the string that is executed is "menu3sub4hypo8". It craps out after the first number is reached.What I really want is that the array gets filled with [1, 2, 3] in the first example and [3, 4, 8] in the second example. How in Helsinki would I do that? Does the exec function need to be looped in any way?
Not so important right now but thinking a little down the line: what regular expression would I need to find "25" instead of just "2" if I run this RegExp.exec on a string that may look like this "menu25sub3hypo6"?

So as you may or may not know, BlazeDS (open source version of LiveCycle Data Services) is a nice way to get your server-side Java and client-side Flex application to play together. Unfortunately, it does have several pitfalls that need to be corrected. I'll try to explain one of them here.
All of BlazeDS's configuration is written via XML files in the flex/ folder of your webapp. The default names are separated for clarity, such as services-config.xml, remoting-config.xml, messaging-config.xml, etc. In these configuration files (particularly services-config.xml), Channels are defined; these setup URIs and objects used to capture and send information between the server and the client. In these config files, it is quite common to use a syntax like so:
[Code]...
Unfortunately, what they don't tell you is that some of these key-in replacements (ie: {context.root}) are not replaced dynamically upon execution but upon compilation of the WAR file you intend to distribute. Obviously not a good idea when switching domains.
So, instead I seek to dynamically define these channels. According to the documentation, that's all good and fine, but it only works if the channel already exists when the webapp is launched. I feel like that sort of defeats the point. So my question is, how do you truly create channels dynamically so that both the client and the server recognize their existence?

I am changing colors of an mc dynamically, in this way: I have an mc of the color green for example. What I want is it to turn to a specific color in time. I have in that mc a sprite, that is that specific color (red in this case). iIset it's alpha to 0 and put it in the layer above the green part. Now when I set its alpha to 1, it will be that colour. When I set it to 0.5 ofcourse it'll be a mix between those colours. Is it faster to do it, but changing 0xFFFFFF? I wouldn't know how to do it though. i want to be able to tell it to go 3/4 of color nr 1 and 1/4 of color nr 2, for example. i also want to be able to choose those colours specificly, for the sake of art. so just choosing 0xFF0000 for red, wont do, for artistic reasons.

I'm trying to merge two display objects into a single new BitmapData object, when it uses the color from one and the alpha channel from the other. The concept seems straight forward enough but I'm getting lost in the BitmapData APIs. I've been trying to use the Alpha blendmode with draw() but that doesn't seem to work.

I have a button I am creating from 2 movieclips in the library. One is the button body (shape converted to MC). The 2nd is a series of button logo PNG's for an additional visual button state change.I add the logo MC with addChild to the button body. Then I add the button body to display/stage container. ll is layered correctly.If I add alpha or transform the color to the button body, it goes to the top - covering the button logo.Not applying the color or alpha to the button body and applying a color or alpha to the button logo has not effect (displays correctly).

Ok the fourth page of the website is a portfolio page with 16 thumbnails (4 across 4 down) which opens a larger pic on the same page to the right.
I can't figure out what to change. The first and third thumb down seem to be linked and open the same image. Same with two and two down from that and so on. I want to separate them so each open their own image. If I edit it in PS both thumbs change...
I click several times and well thumb one and the third one down is:
onClipEvent (load) {
i = 1;
}

I'm trying to create 2 separate motion tweens - between frame 1 to frame 35 and frame 36 to 65 but it just won't work.
From frame 1 I want a motion tween to frame 35. We shall call the graphic in frame 1, graphic 1 and frame 35 graphic 2.
Graphic 3 represents frame 35 and graphic 4, frame 36.
When I make a motion tween from frame 1 to 35, it overwrites graphic 3 and 4 with Graphic 1. It will not allow me to put graphic 3 into frame 35, only graphic 1. If i put it in, it will automatically swap.
When I make a motion tween from frame 36 to 65, it works. But then when I try to make the motion tween from frame 1 to 35, it swaps it over.

Inside movieClip container, there are colored buttons on layer1 and on layer2 there is movieClip square which covers the buttons. I want to use the color efffects and blending options of movieClip square to make layer 1 alpha. There are some blending options called alpha, difference, lighten and substract but Im not getting the right combinations. I want to make layer1 alpha only by using layer2.

I am using Flash 8 - trying to get started by simply fading in/out using Alpha. I totally get on the first layer converting image to movie, inserting key frame and motion tween, selecting clip and changing alphato 0%. Where I am absolutely lost - is when it comes the second, third, fourth and fifth image. I have tried inserting new layers and repeating the steps - but for some reason 2-5 images do not transition like image one.

I have the code below which rotates a MC and fades it in to 100alpha and then fades it out again to 0 alpha. bearing in mind that all this happens on one frame, is there a way to get rid of the ghost image of the MC once the alpha gets down to 0?
I've tried to achieve this at the foot of this code with the removeMovieClip() but it doesn't seem to work.I know i could just let the timeline play to another frame once the animation is over to get rid of the ghost image but i'd really like to keep the animation to just the one frame...

amount = 5;

I cant understand why when I look in the library I see the frames without the alpha channel and also when I try to export/extract the image again the image dont have alpha channel. How is it that in flash this image has alpha channel and how to get it out like that into PNG? Here is the link to download the FLA:[URL]..
