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.
For the class spark.components.Image
I can access the bitmapData object (readonly) (unscaled). I know the scaling factors of the Image.
How can I get a scaled version of the bitmapData?
I'm trying to copy the bitmapdata of a movieclip in which i have a mask. And it copies by ignoring the mask. It's there a way to make it copy what i see (including the mask applied)?
View 7 RepliesI have a movieclip with an image that has transparency and filters applied to the movieclip.I know I can use "draw" to copy the movieclip to a bitmapdata object, but it doesn't seem to copy the filters and the transparency of the image. How can I copy these so the bitmapdata matches the original movieclip in appearance?
View 5 RepliesHaving trouble trying to scroll BitmapData on a half pixel here is my original code
var speed:Number = 1;
_bitmapData.copyPixels(_backgroundParallax, _screenRect, _zeroPoint, null, null, true);
_backgroundParallax.copyPixels(_backgroundParallax, new Rectangle(0, 0, speed, _backgroundParallax.height), new Point(_backgroundParallax.width-speed,0), null, null, false);
_backgroundParallax.scroll( (speed*-1) , 0);
which works until i change the var speed to .5, which is because .scroll method is expecting int's so i replicated what scroll is doing to try and allow .5 pixels

I am trying to make a flash file that has wmode=transparent that takes up 100% width and height of the browser. I need to take a copy of the contents underneath the flash (the HTML page its floated over) and use that BitmapData to manipulate the content visually.
View 2 RepliesWhen 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.
I am developing an application similar to MS Paint. I am building a Flash Paint application. The basic structure is this. I have two layers namely topLayer_mc and bottomLayer_mc. The actual vector drawing is drawn on the top layer and onmouseUp of the tool, a bitmap copy of the vector graphics on the top layer is taken and added as a bitmap to the bottom layer. The top layer is cleared subsequently. It is working for the pencil tool.
Now I need to create an eraser tool. This is where things get tricky. In the application there is an option to save the image as png, so alpha has top be preserved. So the coventional method of draw a brush using the vector and using the draw method of bitmap will not work. Of course, on a visual level it would work if the brush drawn using the vector is to have the same color as that of the background. The eraser's are rectangular in shape.
The technique I am tring to use is to use the copyChannel method of BitmapData class. Specify a channels (say GREEN channel )hex value as 00 and make it as the source. Then make the destination channel ALPHA. I got it working without using movieclips as shown below.

I'm making a copy of a Sprite via the BitmapData Draw method. It kind of works other than the top portion of the bitmap gets cut off (replaced with transparent pixels). It looks like it's about the same height as the Sprite's y value.
looks like this:

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 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 have the code to copy parts of a huge loaded BitmapData to a target BitmapData that is just the size that I can display. I think I have set the scroll bars of an enclosing Canvas to show the size of the larger image and allow the user to scroll. Now I need to put the selected pixels on the screen. When I try to add a Bitmap component as a child of the Canvas, it get an error because Bitmap is not a UIComponent. What's the best way to put the target BitmapData into an Image component?

View 2 Replieshi 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?

View 1 RepliesI load an png image and add it to the display list. Now I want to add this image more than once, like a pinball game there could be 3,4,5 balls, all with the same image. But I cant add the same image reference more than once to the display list, right? So should I make a copy of it? How can I copy it and add to the display list without needing to load it from file more than once?
I tried using this: [URL] But didnt worked! I use the class Loader to load an png, and I use the Loader.content as a parameter of that function. When I add the result to the displaylist nothing appears!
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

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.
This should be a sample question ,, all i want is to import an image from my computer to a bitmapData , knowing that my image is png .. ?
View 6 RepliesIm 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?
