Flex :: Where In Framework Graphics Object Passed Around To Achieve Drawing
Oct 23, 2009I'm trying to understand how the Flex framework draws objects (Button, Label, Image, etc.). The Button class seems to draw itself by addChild()ing its ProgrammaticSkin. However, where in the framework is the Graphics object being passed around in the hierarchy to achieve the drawing. I want to get to the level of 2D API.

View 3 RepliesFlex :: Set Text On A Graphics Object?
Oct 19, 2011Is there anyway I can effectively call the equiv. of setText on a Flex Graphics object ?Specifically I'm using a custom cell renderer to display data in a datagrid. The renderer uses the Graphics object to set the background colour of only a portion of the cell (say the left half) based upon the underlying data. I would like to be able to have text over only that portion of the cell which has the background colour (eg centred within the left half). I know all the widths (of both the cell itself and the graphics object) but I don't know how I can set text (centred) over the graphics object.

ActionScript 2.0 :: Animated Curve Drawing Between Any Points Dynamically?
Sep 18, 2006I have a world map on which I display some data. I read long and lat coordinates for two countries from an XML file which is updated with different coordinates everytime. I then map the coordinates to X-Y axis using some projection method.
So, I have x-y coordinates for two countries. I wanna draw a curved line between those countries but curveTo method draws the curve in one shot. I want to animate the curve drawing part so it looks like it is being drawn real time.

View 3 RepliesGraph Flex LineSeries / Find Y-value Along Curve
Feb 27, 2010I've created a Flex LineChart that shows high and low tide predictions over time. I'm using the LineSeries with form="curve", which produces a nice sinusoidal wave graph, representing water level over time. The X-axis represents time, and the Y-axis represents water level. The only data points I have to work with are high and low tide values, but I would like to figure out how to determine the y-values of arbitrary x-values along the line.[code]

View 2 RepliesActionScript 3.0 :: Using BitmapData For Drawing Graphics?
Jun 23, 2010I've seen the BitmapData object used for graphics a fair bit, especially in games. Many of these cases have done things in somewhat fundamentally different ways, and I was wondering what the best way generally is.
Method 1: Each animation frame is kept in a separate BitmapData object using an array.
Method 2: The animation is kept in a strip using a single BitmapData object and using the "sourceRect" parameter of copyPixels.
The draw and hitTest methods appear not to provide any "sourceRect" parameter. Most of the code I have seen using method 2 has worked around this by copying the bitmap frame into a temporary bitmap for these methods. This seems like quite a large processing overhead to me. Using method 1 this is generally not a problem, unless hitTest needs to be used with scaling and/or rotation, in which case a temporary transformed copy is still needed it seems as hitTest doesn't except a transformation.
I'm thinking method 1 is the better choice since it avoids having to make temporary copies for the most part, and I don't think it would waste much memory (just the duplicated width, height, etc values?). Is this generally true or is there a reason lots of people seem to do things the second way?
Also is there a better way to use hitTest for bitmaps that have been scaled, rotated, etc?
ActionScript 3.0 :: Improve Graphics Drawing Angle?
Dec 28, 2009I have a code, that draws a horizontal line, then it turns into a slope, and at the end of the slope it draws a circle. Here's a code:
Code:
var xspeed:Number = 1; // defines increments for x of slope
var yspeed:Number = 2; // defines increments for y of slope
var hspeed:Number = 5; // horizontal line increments
[code]....
Create document 800x700 and put this code into main timeline. Now test movie As you can see, everything works great. But there is a problem. The circle is being drawn at 0 degree angle. But I want the circle to match the angle of the slope, so it looks like the slope and the circle are both at the same angle.

ActionScript 3.0 :: MovieClip Sprite Versus Drawing With Graphics
Jan 26, 2012I have a program that dynamically draws a polygon wherever the user clicks on the screen. (using lineto, moveto) However this polygon is always behind the other symbol objects on the screen even though its added last in the childlist. Is there an issue with depth when drawing symbols vs. drawing with lines? How can I ensure my dynamic object will display in front?

View 13 RepliesFlash :: Function For Extrapolating Points On A Spline Curve Or Hermite Curve Similar To Keframe Interpolation?
Aug 26, 2011I was hoping someone could help me working out some advanced data reformatting. What I'm hoping for is a function where I can input a value along with an array of key positions like so:
function remap(percentage:Number, keypoints:Array) { ...
The array would start with the minimum and end with the maximum point, with nested key points along the way. For example, I would input something like remap(0.25, [0:0,80:50,100:100] ) and the function would 'imagine' a spline curve graph from (0,0)-(100,100) with a key point of (80,50), then return the y value that is 25% along that graph.
ActionScript 2.0 :: Plotting On A Curve - Return The X And Y Of A Point Along That Curve?
May 10, 2007I have a curveTo an anchor point and a control point.Then I have a function that will return the x and y of a point along that curve if I give it a number as a percentage of the curve (0 to 1).It looks like this, and works perfectly..
Code:
function drawOnCurve( interval:Number, x0,y0,x1,y1,x2,y2)
{
interval = Math.max( Math.min( 1, interval ), 0 );[code]....
x0,y0 are the start point, x1,y1 the control point and x2,y2 the final anchor point.But... I want to give it a _y value instead of a percentage (interval) and it return where on the curve that would intersect.

Flex :: Drag And Drop Of FXG Graphics
Apr 27, 2011I am building a flex project involving drag+drop of fxg graphics. My graphic is instantiated as below:
<graphics:arrow2 id="object" mouseMove="mouseMoveHandler(event);" />
I get an error: "Call to a possibly undefined method Graphic."
This works if I change my drag-object to Image and replace the 'Graphic' below with 'Image'. What should I use to be able to reference the fxg graphic in the drag-drop? My drag drop functionality is as follows
private function mouseMoveHandler(event:MouseEvent):void {
var dragInitiator:Graphic = Graphic(event.currentTarget);
var ds:DragSource = new DragSource();
ds.addData(dragInitiator,"gph");
DragManager.doDrag(dragInitiator, ds, event);
