I have an Image object, and i wish to draw an elipse on it.
i have tried with
imageObj.graphics.beginFill( 0x0000FF, 0.5 );
imageObj.graphics.drawEllipse( position.x, position.y, 10, 10 );
imageObj.graphics.endFill();
but it doesnt draw anything at all.
how to draw graphic primitive on Image object ?
have been messing around with ppv3d for a small project whereby a ball orbits some text. I would like the path of the orbit to be a visible line with a glow effect on it.at the moment I have a sphere located on an invisible spinning cylinder, with the text in the middle so the sphere orbits it. I've tried drawing lines from one point to another on the cylinder but it's not working.
View 2 RepliesTrying to draw the top of a screw which is at a slight angle as its in perspective. I've tried doing this with the drawEllipse tool but its doesn't seem to be able to let me tell it I don't want it positioned straight, I want it rotated a little bit. I've tried doing it with curve To but it looks rubbish, but then I have only used 2 anchor points.

got another little provlem with flex ... i've made a ellipse and i want to rotate it dynamicly. made a h:slider which change the rotate="" value of the ellipse. and it rotates fine. but the rotation point is in the middle of the ellipse.
i want it at the bottom (y) and middle (x).
there are some transformY and transformX arguments for the ellipse, but they have no effect?

Let's say I have the following MXML:
<s:Group id="b01">
<s:Ellipse x="267" y="96" width="30" height="28">
<s:stroke>[code]....
And that I have a dozen more of these groups with different ID's. How can I modify the fill color of each Ellipse using ActionScript? I know I can do something like this:
b01.getElementAt(0).width;
And that will give me the width of the Ellipse. But how can I access the SolidColorStroke color or the SolidColor fill?
i have a class thats create a class with bitmapData that merge 2 IBitmapDrawable. one of them is 24*20 while the other is 16*16.i want to draw the smaller first in a bitmapData object which its width and height are 24*20 but i want to draw it in the center of the big bounds.

I need to do everything with AS3 since both the image and the text is loaded with an XML. Practically I have a picture and above it I'll put a white level with alpha 70%, but as you can see in the jpg the white level has a "hole" in it that is created by a text.I thought that a way could be to convert the text in a bitmap and then, if it is possible, to use the newly created bitmap to create the "hole" with the white level.
View 7 RepliesI am trying to draw this image dynamically (attached image) so for example if user gives me value of 24 the graph has to be able to draw circles like in the image and split circles into 24 sectors ( draw 24 angled radiuses from the origin) ... How could this be done ?
The trick is once I accomplish this stage I need to be able to track intersections between each radius and 3 circles!!! Well the idea of the graph is that each radius is an answer to a question and can have a dot in the origin , intersection with first circle , second or third (each one represents answer 1 or 2 or 3 or 4... then it connects all dots on each radius depending on the 24 (in this example 24) answers. I've done this witha static graph where I knew there were gonna be 24 but now it needs to be first drawn dynamically because user chooses the number of question.

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:

View 2 RepliesI am working with this function that moves an object around a center point in a perfect circle and am trying to modify it to move it in an oval shape that is 1/2 as high as it is wide?
Basically, I have a set speed
var myVelocity:Number = 0.25;
Then I calculate my Sine and Cosine based on the speed
var myCos:Number = Math.cos(myVelocity);
var mySin:Number = Math.sin(myVelocity);
Then I figure the distance of the the object from a fixed center points along each axis and
var x1:Number = myBall.x - centerX;
var y1:Number = myBall.y - centerY;
var x2:Number = myCos * x1 - mySin * y1;
var y2:Number = myCos * y1 + mySin * x1;
myBall.x = centerX + x2;
myBall.y = centerY + y2;
I have another function that figures x and y based upon myBall.x = centerX + cos(angle) * radius; that is easy enough to modify the radius to become an ellipse, but is there an easy way to mod the one above to become an ellipse? I want to do this to be more efficient with the code and reduce the number of math function calls
I have 7 movieclips on stage I want to tween around an ellipse from different start points. I am having lots of trouble doing this. I used a circle formula at first and then divided the y value by the width of the ellipse over the height. This sort of worked but after every rotation the y value was a little of. That code is:
this._x += (Math.cos(angle * Math.PI/180) * radius);
this._y += (Math.sin(angle * Math.PI/180) *radius)/1.54;
I also have trouble finding the angle of the start point, if it is off they won't travel in the same ellipse but they all have different starting angles.
I'm in the final stages of my Papervision project and I need to have the camera orbit around its target in an ellipse rather than a circle on a mouse drag. The tricky part is I already am using some complicated logic to get it easing as well and I need them to work together.

isCameraRotating = false;
} private function downHandler(event:Event):void {
isCameraRotating = true;

I am making a snow boarding game in AS3. The problem I am having is that I want to leave a trail in the snow behind the board.
I have had a think and feel that the best way of achieving this would be to use the lineTo() method to draw a line form the snowboards previous position to its current position. If I do this all of the way down the slope I would end up with a line almost 23000 pixels long which seems extremely large and will have a major impact on performance.
If I were to convert the trail movieclip to a bitmap would it improve performance? I am targeting a minimum of flash player 9 which I have found to have issues when handling bmp's over 2880 pixels so I think this method might not work.
i need to do something like the swf file am attaching instead of the cube revolving... i need to draw my own image. how to bring this effect in flash. as if now, i have created the cube rotatoin in swift 3d and have exported it as a swf file. also can we draw our own images in swift 3d? (instead of the readymade cube?)

View 7 RepliesThe corners of a rectangle drawn with drawRoundRect are not very consistent when the curve/ellipse values are very low (2-5px or so), most visibly when there's a border added.Even with hinting turned on, there's still a pretty ugly difference. When set to 3px (horizontal and vertical), the right-side corners look pretty close at around 3px, but the left-side corners are very off, and both look to be maybe 1px curved.
View 1 RepliesThe AS3 getBounds function returns a rectangle that is not fitting tightly to a rotated ellipse. Instead it returns an axis-aligned rectangle based on the bounds of a rectangle whose width/height corresponds to the max/min diameter of the ellipse and follows its rotation.
Stack Overflow Q/A about the math of ellipses and bounding boxes
Based on this I took a stab at coding a solution in AS3. So far I have been able to produce a rectangle that fits perfectly along the x-axis, but as I rotate my ellipse it acts very weird along the y-axis. Rather than alternating between 2*r_min and 2*r_max while rotating, it alternates between 2*r_min and 0. My best guess is that I have done something wrong when solving the differentiated t for gradient -> infinity...
Here is an example from my code:
var r_max:uint = 45;
var r_min:uint = 20;
var rot:Number = ellipse.rotation * (Math.PI / 180);
var t_nil:Number = Math.atan( -r_min * Math.tan(rot) / r_max);
