ActionScript 3.0 :: Rotating Around Matrix Point To Specific Angle
Mar 5, 2010I have a slider which I want to use to rotate an image around it's center. This normally is easy but my problem is the clip is made dynamically and the size changes so I can't use the default registration point and I need to assign the center point before I rotate it. I found the rotateAroundExternalPoint function which rotates around a center point fine. How to get it to rotate to a certain angle and then have it stop at that angle. The rotateAroundExternalPoint increments the rotation rather then allowing me to set the angle to rotate to. Is there anyway that I can set what angle to rotate my clip to? It right now increments the rotation by the x coordinate of my slider bar (slider_position.x).
Code:
import flash.geom.Matrix;
import fl.motion.*;
var mat:Matrix = clip.transform.matrix;
addEventListener(Event.ENTER_FRAME,EnterFrame3);
function EnterFrame3(event:Event) {
var center_point_x = clip.height / 2
var center_point_y = clip.width / 2 //
MatrixTransformer.rotateAroundExternalPoint(mat,center_point_x,center_point_y,slider_position.x);
clip.transform.matrix = mat;
}
ActionScript 3.0 :: Skew Image With Matrix, Top Angle Good, Bottom Flat?
Jun 15, 2011I am trying to skew an spark Image object using a matrix. The problem I am having is that it only effects the top angle. I think it may be related to the position of the image (x and y). The top angle is prefect but the bottom is flat!
Here is a bit of code:
//imgA = pixles down from top left coord, I used arctan with oposite over adjacent to get a radian angle
//size
openImage.width = imgW; //say 200
openImage.height = imgH; //say like 300

Javascript :: 3D Rotation With Axis & Angle?
Sep 28, 2010I know 3D rotation is well documented on SO and many other sites, but despite reading countless explanations I still haven't figured out where I'm going wrong. My background is in art and design, not math and programming, and I'm never really certain if my angle of attack (no pun intended) is the right one. Rather than paste a patchwork of my dismal code, I'm including an image describing my problem. What I'd really like is a step-by-step worded breakdown of how to solve it. Pseudo code is useful, but I will learn more if someone will just aim me in the right direction or point out common pitfalls.

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.

View 6 RepliesFlash :: Get Scale Of A Matrix Object?
Mar 14, 2011Most often, questions are asked about how to scale a DisplayObject, and the answer is usually to use a Matrix.
My question is, how to you GET the scale of a Matrix (scaleX and scaleY)?
There's a Matrix.scale method to set the scaleX and scaleY, but it doesn't return a value, and no other properties exist to read it back.
The reason I ask, I'm using object burried deep down into a Display list, and each may be transformed. So I use the child object's sprite.transform.concatenatedMatrix getter, but am stuck at this point on how to read the scale from it.

ActionScript 3.0 :: Use Matrix To Scale Of TextField
Jul 21, 2009Unfortunately geometry is not my strong point and I am on a deadline. I am trying to determine if a textfield is larger than a displayObject and that it does not sit outside the x and y of said object. If it is larger, I need to scale it and make sure it is always in the confines of the displayObject space. On a side note, i need to scale the size of the text accordingly.

Apr 28, 2010I am trying to copy an image.The green stuff on the first image is a mask(which is not set, its just there to show it)Everything works fine when I dont set a mask to an image (picture 1)But when I set the mask I get picture 2.What I want is to copy a part of the image which is visible when the mask is set. I know what size the mask and image are going to be so I can calculate the size of the area which i need to copy.This is the code I am using, image has registration point in the center, thats why i use matrix.translate (not sure if its the right way).Also there is no image scaling applied (there might be later), thats why I am using matrix.scale.

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.
