I am building a diagramming tool using Adobe Flex 3. I am about to implement connector lines and I have a question.
Imagine I have 2 squares at random positions on the canvas. I need to draw an arrowed connector line between them. I need it to tend to the target square's center but end on its border.
How do I find out the exact points between which to draw the line?
I have one left panel in which there are different shapes like start,end connectors..... when i drag line image inside canvas i want to draw line/connector between two shapes how would i do it
View 1 RepliesI want to develop an image editing application in Flex 4. My initial requirement is to draw various shapes like Line, Rectablge, Triangle, Circle, Star etc in appication. I want to facilitate user to draw shapes using rubber banding like professional applications do.
All shapes would be vector and should look smooth in an size. So, can't use bitmap and scale them.
What are better methods to achieve this?
I 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.
I have 2 shapes drawn with the drawing api - the points are stored in an array like this...
private var shape_points : Array = [ [81,61],[81,46],[84,43],[84,0],[11,0],[0,5],[0,48],[69,48],[81,61 ] ];
Both shapes have the same number of points. I need to tween the points from one shape to the other using tweenlite/max or tweener.
If I want to draw the stroke of a square just using actionscripting, I can (i.e moveto()).That will just show the stroke of a square as soon as I play the .SWF file.Let's say I want to animate the drawing of the stroke of a square from one point to the next. This way when I play the .SWF file, it will show the square being made. How would I go about doing so?

View 1 RepliesOne thing that seems particularly easy to do in the Flash IDE but difficult to do with code is to outline an organic shape. In the IDE you can just use the inkbucket tool to draw a stroke around something. Using nothing but code it seems much trickier. One method I've seen is to add a glow filter to the shape in question and just mess with the strength. But what if i want to only show the outline?What I'd like to do is to collect all of the points that make up the edge of the shape and then just connect the dots. I've actually gotten so far as to collect all of the points with a quick and dirty edge detection script that I wrote. So now I have a Vector of all the points that makeup my shape. How do I connect them in the proper sequence so it actually looks like the original object?[code]
View 1 RepliesI am simply trying to draw a rectangle inside of a panel using flex4. I am using spark instead of mx. It complains about addchild being replaced by addelement; however, addelement expects type ivisualcomponent. I think sprite should be of that type; however, it reports an error when trying to use the below code... I have tried a few different ways. I think I am missing something very basic about flex 4.

View 1 Replies(MX2004)I have made a 'whiteboard', users can draw on it, change width of pen, clear it.
I need to:
1. allow users to add text as well as lines
2. allow them to add a circle or a square
3. clear last stroke/shape
4. save the drawing
5. email it or print it
I want to draw lines to make a region so that anything inside that region is deleted. The Case : You could say that there are many movieclips in stage but when I just selected by drawing circle or something even complex shape to it purposely then anything inside that shape is just gone.
View 3 RepliesI am in the process of learning AS 3 and Flash on my own and currently using the Actionscript 3.0 Adobe Classroom in a book CS4 version. Having a problem with the Lesson Adendum if anyone has done it. This lession requires you to create two buttons. They both draw shapes on the stage. When one is clicked, it draws Rectangles on the stage following the mouse movement. When the other is clicked, it draws Ellipses instead. The problem I am having is that it just draws rectangles and not ellipses when the 2nd button is clicked. Would be greatful if someone could tell me what i am doirng wrong. Here is the code that I have so far. Apologize for the commented out code, I left it in to show what I have tried:

When you use Graphics object to draw very large shape(that does not fit in 10000x10000 pixels) stroke width may become much wider than value specified in lineStyle function.For now I have only two options:
1. When drawing line you can split it into several lines. However this trick does work only for drawing lines, polylines and polygons. There is no way to apply this to drawing circles and ellipses. Well, we can approximate circles via bezier curves, but this approach seems to be very inefficient.
2. Perform manual cliping. But this require manual implementation of different cliping techiniques, and I think ActionScript does not suit well for this sort of task. And again there is need to approximate visible parts of large circles.
I am using Flex 4 and AS3 and I am trying to make it so that the user can draw a freehand line with the cursor - I have this part done.However, I also need the line to be a dashed line instead of one solid line like it is now. below is my code I am using. I have found some examples on how to do this, but they are all for straight lines, not for a freehand line.
Class File (DrawingArea):
package
{
import flash.display.BitmapData;
import flash.events.Event;
import flash.events.MouseEvent;

I know Sprite.graphics is pretty easy to use, but I was wondering if there is any ready made libraries for drawing, resizing, moving, layering, etc.. of various display elements? Also, stuff like tool selection, maybe some effects, premade shapes. Anything you would recommend?
View 1 RepliesI am developing a white board application which allows the user to draw line with arrow head (some like Microsoft Word line with arrow feature). I am using graphics property along with lineTo() method to draw a line. Now i have to draw a angular arrow on the last point of line. I am drawing the arrow by connecting the points around last points. As 360 line can pass through this point and each line can have a different angle of arrow.

View 1 RepliesIm building a pretty simple drawing board in flash, i got this code from this forum and it works fine (there is more to it but this is the drawing part)[code]This works fine. But i want to be able to erase the drawings, step by step this is ths tricky part, ive looked everywhere(ok not everywhere) but in a whole lot of places but the only thing i found is how i could delete everything with removeChild and that in not what i want. Maybe i need to change the function abowe? Please help me to get in the right direction. What should i read about /look at?
View 5 RepliesI am trying to work with this flash tutorial -[URL] So far it draws with a simple rounded line. I have been extending this application by making the drawing board bigger and other small things. I now want to be able to choose the line style. Currently it is rounded and I want to choose and draw with other shapes - square, forward slash (/), backward slash (). Is this possible? If so, could you explain how I could go about it?
View 1 RepliesHow do i animate a drawing line? I mean like from point A to point B, the flash will show it is "drawn" itself.Can I do it simply without actionscript? Is it possible? Because I have many lines to draw, to make it into a diamond.
View 14 RepliesWhat I'd like is the ability to draw a line with the drawing tools in Flash, and have that line appear onscreen as if it were being drawn. I don't think there's a way to do that with the animation tools (I'd like to give it a go, but I have no idea, once I've drawn a line and converted it into a symbol, how I could access the anchor points and whatnot of said line to then do some funky stuff with curveTo, or whatever better solution is out there...

View 1 RepliesWith several flashes I'm trying to create, I find that I need to know how to depict a line being drawn or a plant/vine growing (same concept right). Obviously frame-by-frame animation can be used, but that's quite tedious. There must be some other, more productive way to pull it off. Example of the vine: [URL] I've tried shape tweens with shape hints but it didn't render very well at all.
View 6 RepliesI am looking for a smooth line drawing effect as in the pencil tool in Flash. I need to implement the same using as3.
View 7 RepliesI'm having troubles with the width of a line using the lineTo and lineStyle function, I can put setting the thickness and noScale parameters, and it works fine for no longer lines than 32000 pixels, but when I try longer line, the thickness changes to a bigger width. if you want to try what I'm saying you can prove this by changing the num variable:to 33000 for example:
num = 32000
this.createEmptyMovieClip ("Envolvente", 100);
this.Envolvente.lineStyle(0,0x00CC00,100, false, "none",
"round", "miter", 0.8);

i'm developing a game for mobile devices where I need to draw many objects and some lines(1~3 just occasionally).
my problem in short is: Line drawing is too slow for iPhone4
objects are drawn with bitmap, so it's pretty fast with GPU support. drawing lines are slow.
a end point of a line follows mouse cursor, so it changes every frame.
here's how i did it
initialization step:
var img:Shape = new Shape();
addChild( img );
[Code]....
that gives me 47~48 FPS on my iPhone. +2 FPS but still way too slow for a simple line.
without the line, i can maintain my whole game around 30 FPS. with the line, it goes below 20.
i want to draw a line with actionscript .Here is my code
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"[code]......
I was told that by using actionscript to animate, it will make the flash file smaller and animations smoother... is this a correct assumption?
with this in mind, I have the code:
ActionScript Code:
this.createEmptyMovieClip("myLine", 10);
myLine.lineStyle(2, 0x000000, 100);
myLine.moveTo(10, 10);
[Code].....
