Flex :: Animating A Transformation Based On Transform Matrix?
Oct 18, 2010I have a UI component that I wish to relocate and scale, but in a rather complex way. I've figured out the necessary transformations using the transform matrix, to which I applied several translate and scale operations. I can set the new transform matrix for this UI component to be the above calculated matrix, and the results are accurate; but I need to animate the transition. I can't use the Scale/Move effects alone because they aren't as powerful when it comes to calculating the necessary transformation as the matrices are.So how can I animate the transition of an object given a source and a target transform matrix?Figured it outUsing a tweener and its onUpdate event to reassign the matrix with each intermediate value:
var animMatrix : Matrix = gi.transform.matrix;
TweenMax.to(animMatrix, 1, {

Actionscript :: Get Transformations From Transformation Matrix In Flash?
Sep 1, 2010I have transformation matrix properties (a,b,c,d). How to calculate scaleX, scaleY, scewX, scewY and rotation angle from those values?
When only one type of transformation is applied, I can figure out that:
scaleX = a
scaleY = d
scewX = c
scewY = b
rotation = arccos(a) or -arcsin(c)
But when multiple transformations are applied at once I don't know how to calculate those values.
I need to do this outside of flash so I can't use any flash helper methods.
Flash :: Bitmap Data .draw() With Transform Matrix
Jun 29, 2011I'm working on a project wherein a user can take a snapshot of themselves using their webcam and then edit this image by transforming scale and rotation and save the result.
I've got most of it working, the user can take a snapshot of themselves, transform the object using Senocular's Transform Tool and i'm using .draw() to then save this transformed object. The problem is .draw() is only grabbing data from the top left corner of the stage. It is drawing the transformed object but only from the top left corner.
Why does it only draw from the top left corner and how can i get set the coordinates to only draw from the area where the captured image is set?
You can view the file as is at: [URL]

View 1 RepliesActionScript 3.0 :: Recalculate Point X / Y Value After Matrix Transformation
Jun 16, 2010I am doing a matrix transformation on a Display Object. I got this function from another site, but basically it scales a display object around any point.
ActionScript Code:
public static function scaleAroundExternalPoint(m:Matrix, x:Number, y:Number, multiplier:Number):void{
m.translate(-x, -y);
m.scale(multiplier, multiplier);
m.translate(x, y);
}
But my problem is that I have to do multiple scales in a sequence and after scaling, the points defined in the XML no longer correspond. Let me first say that all the points being scaled around are located in an XML file. They are all relative to the display object's registration point (0,0) when it is normal, i.e. a scale of 1. Also, I have created a class that retains the target object's original Matrix so that the percentage you pass in is relative to the original scale instead of the scale after each call. But basically, with the scaleAroundExternalPoint function by itself, if I have an object that I scaled to twice it's size, the multiplier would be 2. but say I want it back to it's original size. The multiplier would NOT be 1 since that would just leave it at a scale of 2x. It would have to be .5. The important parts of the class are below.
ActionScript Code:
public function ZoomUIComponent(isKeyboardControlled:Boolean = false, disabledAlpha:Number = .25,
max:Number = 2, min:Number = .5, precision:uint = 2,
seconds:Number = 1, step:Number = .1):void{
this.disabledAlpha = disabledAlpha;
this.inControl = InteractiveObject(getChildByName("zoomIn"));
_isKeyboardControlled = isKeyboardControlled;
[Code] .....
It's retaining the original matrix and then calculating based on that EACH TIME. So how would I find the new X and Y values of the original points so that I can scale around them?
ActionScript 3.0 :: Numeric Transformation - Transform 100 Into The Scale 1 To 20?
Feb 29, 2012I need to scale numbers. I'm using perlin noise to create a random 2d scrolling map. I'm using Blue channel data with values between 0 and 255 (I believe).Each pixel represent a value of height of a tile. For that reason I have to transform this value into a valid value.For example, If my 2d scrolling map has 20 tiles of maximum height and the pixel in the first position is 100.I have to transform 100 into the scale 1 to 20.

Mar 24, 2011i've filled a circle shape with the bitmap data of a bitmap asset.i need to rotate the circle from the center, so i added the bitmap to the center of the circle and used a matrix transformation to shift the bitmapdata upward and leftward so it appears centered.
now i'm trying to read the bitmap data with getPixel() but the return value is off since it is returning the untransformed position of the bitmap data instead of the visible transformed bitmapdata.
Bitmap(Sprite(evt.currentTarget).getChildAt(0)).bitmapData.getPixel(evt.localX, evt.localY)
how can i get an accurate reading of the pixel data from a bitmap with a matrix transformation? updated with code. assume the redCircleData in my example is more colorful and something worth retrieving pixel data.
var redCircleData:Sprite = new Sprite();
redCircleData.graphics.beginFill(0xFF0000, 1.0);

ActionScript 3.0 :: Transform Matrix TopLeft?
Dec 29, 2010I ran into an issue with an app that I have been working on.The application lets a user draw a rectangle, which base class is UIComponent, on an SVG Canvas. The user can rotate, skew, scale,flip horizontal and flip vertical the rectangle. Then they can drop an image into the rectangle.We just cloned the rectangles matrix and applied it to the image and the image would transform the same as the rectangle. Well now we have changed the way the app works.
Now we don't want the image rotated or flipped on the initial drop, and this is where I'm having trouble.I was wondering if there is a way to always find the true top left of any rectangle no matter what kind of matrix is placed on it. I can find the center of the rectangle but when a user flips the rectangle the center point is outside the rectangle.Instead of finding the center I would like to find the topLeft.I have tried several things. Like transform.pixelBounds, but this gives me big numbers like 2200 instead of 400. I have also looked at senocular.com but not sure that I understand it.I just need a dynamic way to always find the top left.
ActionScript 3.0 :: Assign A Transform Matrix To An Object

ActionScript 3.0 :: Matrix Transform - Rotate Object Around External Point
Oct 14, 2010I found the function:
rotateAroundExternalPoint(m:Matrix, x:Number, y:Number, angleDegrees:Number)
to rotate an object around an external point. The top of the object will always point at the center point which is exactly what I want.
It works fine but its possible to rotate it in an oval instead of in a perfect circle...I think it should be something with the angleDegrees Parameter but im not sure what to do with it. I also tried to set up an own matrix but I failed. Any right direction to orbit an object in an oval, and where the top of the object always point at the rotation center?

Its a simple skew transformation.Currently i have two possibilities:I am creating the finished wall in photoshop, save the file as PNG (because of transparent areas). Because i cant import PNGs at run time, i need to create all possible textured walls. A lot of work if i have a lot of textures (Say, i have about 200? )I am importing the original Texture into Flash, and perform a free transform directly in the MovieClip. I still have a lot of work because i have to do this to each textured wall!I would like to do this transformation in Actionscript, so i could import any texture JPG at the runtime (LoadMovie) and just need to have the File names stored somewhere or retrieve them and so on.
I didnt find any possibility to perform a skew transform to a MovieClip in Actionscript..The transformation is just like this: Rotate by 45 deg. (CW) and reduce the height of the finished transformation to 1/2.i am able to apply the _rotation and _height transformations, but the second transformation is always applied to the root object, which often might be very helpful, but right now its not.

ActionScript 2.0 :: Fast Color-transformation Over MovieClip With CacheAsBitmap?
Jun 3, 2009I have a very complex vector symbol on the Stage - background_mc. I have set background_mc.cacheAsBitmap = true.This turns background to bitmap and makes Stage repaint fast.Every frame the background light changes.I use the following code to alter the light.
(new Color(background_mc)).setTransform(light);
And here is the problem.The code works very slow.I guess because the light is applied to the contents of the background_mc.And then a new cached bitmap is resterized once again.The same code over BitmapData of the same size works much faster!Is there a way to tell Flash to apply color-transformation to the cached bitmap, instead of underlying vector symbols?
Note, that background_mc is scaled when Stage is resized.This is not so fast, but it's good, because the picture quality preserved.If I convert background_mc to BitmapData, bitmap would be scaled.
ActionScript 2.0 :: Matrix Algebra And Matrix Inverse?
Apr 5, 2003Has anyone here ever developed a function (or general library of relevant functions) that will allow one to find the inverse of a matrix? I've searched the forum archives, as well as the internet more generally, but haven't found anything. If anyone has some leads, I hope you'll pass them along.
If I don't hear anything within the next few days, I might try to develop something on my own, but I'd hate to do so if someone has already done the dirty work.
A solution to this problem would be very useful for 3-D work or anyone doing mathematical programming more generally.
