Im working on this project where I get a stream and eventually a bitmap from a webcam. Right now I'm kind of stuck trying to crop a subset from theis bitmap along a path of x,y coordinates. The path will always contain four corners, but these are not necessarily 90 degrees, so It is usually a somewhat skewed square. what classes to use for a custom crop ( not really keen to make one fresh)

View 3 RepliesI just started working with bitmaps and I do not get them at all, I've read the entire page adobe has on bitmap and bitmapdata. I've got this code together but all it does is displays a white rectangle and not my image.
ActionScript Code:
package {
import flash.display.MovieClip;
import flash.display.Loader;
import flash.display.Bitmap;
import flash.display.BitmapData;
This code should load the image into the bitmap (which works), then crop it with the rectangle (which just crops the fill from the bitmapdata)
I have been trying to figure out a good strategy to perform a bitmap crop using Actionscript3. For example: I have a picture of a car and I want to crop out the car from the image alone and feather the edges so that they do not look jagged.
I am a flash noob and have only been using it for a couple of weeks. I've tried a couple of options and here is the last one that I have come up with it: I place red dots on stage that are draggable so that you can outline the object you want to crop and the dots are the bounds for a gradientFill that is used as the bitmap's mask. (I am using a radial gradient ... so the results are far from what I want, since the car is not an oval).
[Code]...
1) How can I fade just the edges of this custom-shaped fill outlined by the red dots?
2) I want to save the image out to a file once it's cropped. What strategy would be better for doing this using a BitmapFill or a GradientFill as a Mask (If it's possible with both)?
3) I may be using this strategy to crop faces later on.. anyone know of any good face detection APIs for as3? (also edge detection APIs)
Does anyone know a way to crop a SWF like you would crop an image in Photoshop? I'm building a Flash Banners application in my Flash portfolio website and I'm loading a SWF using addChild via a URL loader object. There is no way to mask the outsides of the SWF because addChild puts the SWF at the front of the display list so the masks would just show up anyway and the masks will just be huge white sheets that will look dreadful. I need to LITERALLY crop the SWF down to 550 X 325 pixels.

Is there a way to dynamically change the path of the Bitmap on the Library? Using actionscript?
View 9 RepliesThe solution should be straight forward but I cannot find it, my problem it's that I'm reading a xml, and one of the properties inside the xml it's a Bitmap path(string), when I`m reading this xml I would like to convert this string to a Bitmap Obj so I can use through my MXMLs.
View 4 RepliesI'm trying to trace the path of an object by using setPixel on the object's position every frame in a BitmapData/Bitmap pairing. These pixels aren't showing up normally and I suspect I have a fundamental misunderstanding of the BitmapData class. Here's what I'm doing:
public var contrailBase:BitmapData;
public var contrail:Bitmap;
private var contrailColor:uint;[code].....
Using this code, the red pixels don't show up. If I initialize contrailBase to 0xFF000000 instead then I get a black screen on which the red pixels DO draw, but I need the bitmap to be transparent except for the contrail. What am I doing wrong?
So I've created a script where a mc is clicked on and the player can draw a path using the mouse. I'm trying to figure out how I can get the mc to follow the path drawn out by the player's mouse and when the player clicks again, it erases all of the path.my code is below

the same class is passed to the mxmlc compiler in SWF library as a symbol linkage class and again in a source-path. But the compiler uses the definition from the source-path so creating new instance of that class won't create new instance of the library symbol. How do I tell the compiler to prefer the definition linked to the symbol (the one dfrom SWC)?
I have my design assets in an FLA file and they are linked to classes (e.g. [URL]. Then I export those assets to a SWC library and pass it to the compiler. Now when I create an instance of the class (new MyAsset();) it will be a new instance of the library object.
But there are other classes too in the source folder (e.g. "com.myproject.model.*" so I need to pass the source folder to the compiler too. And that is the problem, now the compiler will use the MyAsset.as definition from the source path, not from the SWC where it is assigned to the library object so if I create new instance of MyAsset now it won't duplicate the library object.
Here's what i'm trying to do: Hide a MC depending on the path variable as:

I was wondering if it possible to write up some AS that will take line paths that you have drawn and convert them into a Path object? For example say you drew a jagged line from left to write, would there be a way to have AS convert that into a Path object.

I am displaying some flash content on a fairly standard page. This works really well when the flash, xml file and html page are sitting together in the same directory.url...However, I want to display that same content in another page which is deeper inside the site but outside of the directory that houses the .swf and .xml files as well as the assets.[code]The js files are loading properly but the flash content is not, so I could use a little help getting that sorted out.

View 1 RepliesI'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.
[Code]....
I know the topic of "duplicating" movieclips is a hot issue with the new virtual machine. Luckily, I understand the implications. I only am [currently] interested in duplicating a Bitmap. See, I load an image from an URL using 'flash.display.Loader.load', which is a non-blocking operation in Flash Player.However,I may use multiple copies of the loaded image (which is reported to be a Bitmap, naturally) in the display list at the same time.Hence, I naturally do not want to load the image from an URL every time, because I don't want to wait for a non-blocking call to complete. Nor do I need to - I mean one copy is already loaded, so it should be possible to just "duplicate" it, right?
My idea is to do use the bitmapData property of a Bitmap and pass it to the constructor of a new Bitmap object. I have not tried the following in action, but I want to hear whether any of you did and if the following would not work, what would:
Code:
var original_bitmap: Bitmap;
var copy_of_original_bitmap: Bitmap = new Bitmap(original_bitmap.bitmapData);
LiveDocs mention that the BitmapData being passed to a Bitmap constructor is "being referenced", which to me might suggest it cannot be used twice? There is also the BitmapData::clone() method, which I am not sure is applicable here or not.I know this is a lot of talk instead of just trying this out, but I test so much Flash Player code daily just to see "what works" (which should be documented instead by Adobe),
I have a 'puzzle' with the pieces 'scattered' haphazardly around. These pieces are all instances of my PTPuzzlePiece.as class, which works great for all intents and purposes. When the user selects a photo from the picture library, the pieces all properly display their 'masked' portion of the image. However, I have a problem in that the masked bitmap displayed in each piece is only 'masked' and not cropped.
This means that, for instance on the third piece down on the left hand side, 100 not-visible pixels of bitmap extend below the piece and out of the 'framed' area. This totally throws off my calculations when I go to scale and then print the screen using the AIR PrintJob, and when I scale that 'card' down to a 'button' on the menu where the user chooses which 'card' they wish to use. Is there a way to crop the not-visible area out, or copy only the visible pixels as BitmapData into a new Bitmap entity so that the layout is entirely contained within the 'frame'?
I have drawn objects outside the stage in the belief they would be croped automatically when creating the swf. BUT it doesn't. The objects are of course on the stage but pour over the edge... Anyone who knows what I need to do? To actually draw the objects inside the stage can be trickey since they are sort of supposed to be bigger than the stage. If I draw them inside the stage there is a risk of a little gap.

View 1 RepliesI'm working on a game, and to keep performance good, instead of addChild'ing 50 new sprites to the stage every second, I decided to have each player draw to their own bitmap, and then to the 'master' bitmap.

Code:
