ActionScript 3.0 :: Using A Png Image As A Mask?
Nov 18, 2011
I recently tried using a png image from the library as a mask for a movieclip on stage. Much to my surprise, the mask is just a rectangle. I expected it to ignore the 0-alpha pixels in the image and just mask out the visible shape. I managed to come up with a work around, but I just wanted to know if it was possible to use a png image as a mask and get the shape of the visible image as the mask as opposed to the whole, rectangular image area. I totally thought it was.

maybe point me towards a better way to mask. png file is way too big. I have been using the mask layer option to create my own mask around a jpg image by drawing around it on the mask layer. There has to be a fetter and faster way to do this. Is it possible to maybe have a specific color range have an alpha value of 0. Similar to green screening whereas If I put the item I want to clip on a green background flash will auto take out the green for me. and by auto I mean action script maybe. I think this can be done but im not finding it.
how are these guys clipping these images [URL] they have the movie clips set up where the black background on the 3 layers of shoes is getting masked out. When I go into the shoe movie clips I see there is a black background but it just disappears when I go back to main timeline.

my issue is this, my users import an image with FileReference and I need to mask it and then send it to server.My problem is this: I'm be able do keep the filereference event and transfer the image data into my canvas. I'm be able to send to server the result of masking.But I'm NOT be able to mask the image that my users have load in my canvas.

I want to use a b/w image as a preloader and as the content loads, the image gets colored the same percent. Just like a regular preloaderbar, just that the counter is the color.

I've been playing around with the gallery in this tutorial.[url]...
I was wonderig though, if anyone knows a way to create a mask transition between each loaded image. I fiddled around with it a bit, but can't seem to come up with anything, and I was wondering if it was even possible?

Flash CS4 AS2 Okay -I have a flash movie, and I want to apply a mask to it. The mask I want to apply, or rather, the "shape" of the mask I want to apply is an external image that was made in photoshop. The shape is an irregular one with a bunch of jagged edges. the shape itself is solid, with a transparent background. I've tried saving it as a PNG with transparent b/g, and I've tried importing the PSD file directly into Flash - however - when I go to use this shape for a mask, the mask that is applied is an entire rectangle bounding the imported image - rather than along the edges.Hopefully you can see what I'm trying to do here, and perhaps offer some insight on how I can get this image into flash (let's stick with the idea that the jagged edged manner of the image is too difficult to recreate inside of flash).

I am working on an animation with two masks, which plays in Flash as expected, an exported SWF is ok, an exported Quicktime is ok, except for the dreaded ghosting which renders it useless, but when I export it as an image sequence (gif, png or jpg), one of the masks is consistently ignored, while the other one masks as expected. This already shows when I export one single frame as an image. As a result, I currently have no way to create a quicktime movie for this animation (running CS4 on OSX 10.6.5)
Any other way to arrive at a quicktime movie?

I'm using FlashDevelop, trying to create a wipe away effect. But for some reason, if you hold the mouse button down for a little while in one place, the underlying image (ice) gets erased and reveals the default background. How do I prevent that from happening?

package MyProjectPackage
{
import flash.display.Bitmap;

I'm a self proclaimed n00b when it comes to as3, but I'm learning rapidly.I followed this guide and created a great particle system: url...What I'd LIKE to do, if possible, is make those particles that are generated be the only part of an image that shows(mask). The tutorial contains a fla with a movieclip of a circle, two classes...particle and ball which call the movieclip and generate it on the stage.

I am doing a multiple mask where an image is being masked by multiple little squares that drop down.I created 2 layers, mask and masked for each square and image.That part works fine, however, I wanted to load a different image everytime when the page loads, I used the example on this site:
choice = Math.round(Math.random()*6);
switch (choice) {
case 0 :[code]...
Now, every little square load a random image instead of all loading the same image. Is it possible to ask all other masked layer to call on that one random image? What should I do?

I wish to stop my mask being dragged outside the bounds of the image. The current set up I have is as follows. I created a circle and added a blur; I then exported it for action script setting its class as a sprite with the class name "Circle". I also made my image i was going to mask a Movie clip with the isntance name "mc_bee". In the actionscript I added it to the stage, positioned it and cached it. I tried to add in actioscript to create the bounds the image the mask is making with the code below:

I have a logo that I'd like to animate for a class presentation. The logo can be seen here: [URL]. I would like only the word LEAF to fade in, and then the blue portion to wind its way around (Starting at the gap at the top, going clockwise and finishing by revealing to two shorter lines in the center). At first I tried to mask the blue portion in segments, but couldn't figure out how to link multiple symbols together to mask the same image.

I'm just starting out with Flash, I'm using ActionScript 2.0, and trying to acomplish something seemingly simple but it is not happening like I would think it should,'m trying to load a large image about 3000x2000 pixels and then mask it with a small square, so that later I can scroll through the image to view it.Here is the code I have so far, it produces a blank white screen.
createEmptyMovieClip("container", getNextHighestDepth());
container.createEmptyMovieClip("fullImage", container.getNextHighestDepth());
//When I replace the above line of code with the line of code bellow the image is displayed

I'm having trouble setting up a Graphic object (a solid filled rectangle) to be masked with an image that gets loaded at runtime. I've managed to get it to work with the following code:
<?xml version="1.0"?>
<s:Application xmlns:fx="[URL]"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
creationComplete="init()"
[Code] .....
Setting the PNG inside the <s:mask> makes the stage render nothing, while adding the mask programmatically in the init() method causes correct behaviour. It took me quite a while to figure this out and I'd like to understand what it is that I'm doing incorrectly in the MXML approach, as that seems to be what is being done in the Cookbook (other than me using an Image and the example using a Group wrapped BitmapImage).

I am wanting to achieve a particular image effect using Adobe Flash (Actionscript 3). I would like an image (width 200px, height 600px) to appear on the timeline by being revealed by different sized circles (varying from 30px-5px). I am thinking of using an image mask and creating seperate circles across the timeline, so that when the movie plays, each random sized circle, one after one, will reveal the image at the end. So this is probably going to be quite time consuming. Also, does anyone know of any flash image effects helpers in general, I'm looking for something similar like green socks except for image effects...

I've got a sprite object that gets a custom shape loaded into it, that gets used as a mask so as to cut out a custom shape from an image that is loaded in with a loader object - The loader(loada) and shape(lines) objects are both children of the sprite object - I've added code to save out the image from beneath the mask but when the save function is called nothing is saved out, and no errors are thrown.[code]

I got 1 movieclip, in that movieclip I got 1 image in 1 layer and in other layer I got one matrix of squares. So then when I mask the image I only get only the images by squares. I am trying to had a motion so that some squares shine over the time.

Eventually I would like it to show our projects along a horizontal axis, when the user clicks an image additional images and text is revealed. At the moment I have got the horizontal axis working with images loading in and separating into each project. Now I am trying to code it so that for every project a mask is loaded in with the height of the mask equaling the length of the pictures (which I think may need me to restructure my code). So that only the first image is shown.
The important code for this is:
function processXML(e:Event):void{
var myXML:XML = new XML(e.target.data);
xPos = 0;
yPos = myXML.@YPOSITION;
thumbWidth = myXML.@WIDTH;
thumbHeight = myXML.@HEIGHT;
[Code] .....
I'm not sure if i need to restructure the code so that for every project in the xml file it inserts the images of that project into a new movieclip, not sure how to do that though.
