AS3 :: Flash - BitmapData Of A Masked Image?
Dec 14, 2009
I am trying to take a snapshot of the masked region of an image... so, I load my image then perform the following functions:
private function manageLoadedImage(e:Event):void
{
_bitdata = e.currentTarget.content; // get the bitmap
_bithold.addChild( _bitdata ); // add the bitmap to a sprite on the stage
[Code]....
I have a movie, inside that movie I have a thumbnail editor name ThumbEdit.
ThumbEdit has a movieclip on its stage called "holder1". In the document class of ThumbEdit I create a sprite "_bithold" and place it on the stage at holder1.x and holder1.y. When the image loads, I add the image to _bithold and then mask _bithold with a shape. So, I want to grab a snapshot of the masked region of _bithold but I'm not sure how I should go about doing that.

I'm using BitmapData.Draw to draw a masked movieclip to a bitmap.Flash behaves very strangely in many different ways. To give a couple examples:1) Normally, the position of the mask is relative to the masked object. Ex. if I Draw() the movie clip at 10,10 and the mask's position is 20,20, then during the Draw() the mask will effectively be at 30,30. Weird, but consistent. However, if I Draw() the mask to another surface first, and then Draw() the movie clip, the mask position will be absolute (20,20 in the example)

I have a Movie Clip object with a timeline, and it has 3 layers: a layer to stop the timeline at the last frame, a layer with regular drawing with mask attribute and a layer containing a target movieclip with the instance named 'target', that is masked by the layer above.
The drawing is very simple, not even a movieclip, just vector drawing. It's supposed to show the target movieclip only on regions where the mask layer has some drawing, right?
So, I created the method to load an image, listen to the complete loaded event and add the image to the target masked movieclip, but it disappears after the first frame! If i delete the layer with the mask drawing, works fine.
Here's a smaller version of the code.
package
{
import flash.display.*
import flash.events.Event;

change the following php/AS3 to make it save the dynamically created masked image to the server instead of offering it for download? You have to pass it variables from the as3 AT THE BOTTOM OF THIS POST...
PHP -
<?php
if(isset($_FILES['Filedata'])) { // basically if file data exists to actually upload.

I would like to have an image that is wider than the viewing area be viewed by dragging a slider left or right, it's basically just a custom scrollbar. My first inclination is to make a mask and put the image behind it, and then I assume I would have to connect the slider to the image somehow so when user clicks and drags slider left or right, the image slides with it to show the part so it that are obscured.

I'm trying to write some ActionScript which will accept a mask and an image, then mask the image and put a border around the result (assuming that the mask is always 100% opaque).
For example, if my mask is a poorly drawn star, and my image is a bunch of flowers, I want the result to be a poorly drawn star with flowers inside it and a border around it. Something like this:

I'm creating a shape in code based on some random points and then using it as a mask for an image. What I'm hoping to do is have the mask fade the image to transparent around the edges. I know I can do this using a gradient mask, the issue is how do I create a gradient on a shape that just fades out around the edges? The shape is not regular, so a radial or linear fill just won't cut it.

Alright, is there some way to keep a clip with masked content from reacting to the mouse?'ve got a button clip with a masked image inside (so the image that goes beyond the button's bounds can't be seen), but, when the mouse rolls over the masked-off image area, the button still reacts. I've been looking for a few days now, and I can absolutely not figure out what to do!

I am working on a flex project, where I have to load a couple of SVG files and compare their pixels. To compare the pixels, I like to convert them into a byte array (BitMapData). I am able to create a bitmap data for a PNG image, but not for a SVG image.

I am building a sliding image movie. It takes two photos and compares them by using "startDrag" to slide a "setMask" MC horizontally to reveal one photo under another. The idea here is to compare two photos taken 50 years apart.
[Code]....
As you can see I have two MCs here one is a mask and the other is a handle of sort. They work fine separately but I would like to have the two function in unison or as one MC. The handle MC is just that a handle that appears on the left edge of the masked image. So when user drags the handle the masked image moves as well. (or vice versa)

hi guys, i got this image i scaled down by .5. The user is then allowed to add objects to the image such as flowers that are sprites in the library. So basically, a jpeg that is 800 x 800 is down to 400 x 400 on the stage and the user is able to add objects to overlay the image.
i want to save the image with the flowers and objects back to its 800 x 800, how do i redraw this image using bitmapdata properly?

I am trying to use the reflect class from "http://pixelfumes.blogspot.com/2007/03/reflection-class-v3-with-source .html" but I keep getting this error:
ArgumentError: Error #2015: Invalid BitmapData.
at flash.display::BitmapData()
at Reflect()
at Site_fla::GalleryPage_29/loadThumbs()
at Site_fla::GalleryPage_29/sortXML()
[Code]...
btw, first I used assigned thumbContainer as the mc argument (outside the loadThumbs() function) and it worked but not exactly what I wanted... because I thought it is supposed to update when the movieclip is animated but it actually didn't... when I use a scroller, only the thumbs that are first loaded to the stage get the reflection..

How can I copy or duplicate the bitmapdata from a mx:image component?
I need to display the same image in multiple screens of my application and don't want to have to download the image multiple times.
I could just use a urlrequest to download the image as a bitmap and copy that but I like the way you can can just set the source of the image component.

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);

The image is already held locally on the client PC and it is an Air application. The image is not embedded, it is in the Application Storage directory.
I have seen this question: How can i get a BitmapData object out of a File object from a local jpeg file in AIR? but it uses URLRequest which I don't think is what I need because the file is local.

Im doing this game as final project for graduation and I want all imagery available and dynamicly loadable from a directory without a need to have it all imported into a library.
So is there a way to load external image and convert it to BitmapData or get its content at pixel level?
[edit]Cause I dont see any. If I load it with loadMovie, it becomes content of a MC and I dont know af any functionality to work with a MC as with a bitmap and any other loading method is not know to me too.[/edit]

I've read some stuff here and there, but I dont really understand how this would work. For example, I have an image of 800x500 and want to break this apart in 40 pieces (100x100), how would I do this using the bitMapData and (probably) draw Rectangles which will hold the pieces?

Let's say you have an image of a cartoon human that is wearing a blue jacket with white sleeves, blue shoes, and grey pants. Brown hair and biege skin tone.(My project actually has 1300 of these images - 325 are blue cloths, 325 are red cloths, 325 are green cloths, and 325 are purple cloths)I am having a major problem with file size and memory usage due to all the images, so I have been asked to see if there was a way I could programmatically change the clothing color... this way we can use any color we want, and only have 325 base images.I have been trying to play with color matrix filter and color transform, but I can't seem to get the hang of itIs there a way I can extract only the "blue" colors from the image and do a hue shift on it to the color that I want it to be without effecting the non-blue colors

In Flex, I am using graphics.codec.JPEGEncoder to save image files that are edited inside application (normal manipulations like brightness etc.) I am able to save files perfectly. What I want to know is that is there any way I can save the image with a better dpi? Say, for instance the image that is loaded and manipulated was originally of 72dpi, now can I save it with a dpi of 150 or 300 ? If so, how to do it.
Doesn't have to be using the JPEGEncoder, if there's any way to do it at all, like using any library etc, I am okay with it.
Note: If it matters, I am using Bitmapdata to store the image and manipulations and saving the image with JPEGEncoder by supplying it's data as bytearray like below.
var imageBytes:ByteArray = encoder.encode(myBitmapData);

I need to be able to zoom in on my image, but I cant get it to work properly. I've got an Image showing my content, and it get it's content from a BitmapData. The BitmapData is full-res, which is 2880x1620, and the Image is scaling to fit my window. The SmoothImage is the same as Image, but with smoothing added.
<me:SmoothImage id="imageFull" visible="false" width="100%" height="100%" />
How would I go about zooming this image when I scroll my mouse? This is the code I have, and it does change the scaling factor. But since it's set to fit my view, nothing happens...
public function videoBufferWheel(event:MouseEvent):void{
myZoom += (event.delta/10);
if(myZoom >=1){
imageFull.scaleX = myZoom;
imageFull.scaleY = myZoom;
}else{
myZoom = 1;
}}

I'm trying to grab the BitMapData from an Image, convert it to JPG, and send it to a server where it will be written to a file. It "looks" like it works, the resulting .jpg is the right size and displays in an image viewer, but there is no picture... just an off-white background. Here's a code snippet:
imgTemp.addEventListener(FlexEvent.UPDATE_COMPLETE , imageLoadedHandler);
...
private function imageLoadedHandler(event:Event):void {
if (imgTemp.width == 0) return;
[Code].....
Then send "ba" to the server where it's written as a .jpg.
The data "looks" right when I receive it on the server, correct length, bits look the same.
