Flex :: Draw Lines In Canvas?
Dec 13, 2010
I'm trying to draw lines on a canvas object. When the width of the Canvas is less that the width of the line, it draws outside the Canvas over other elements. I read about this problem and I try to resolve using a inner Canvas with a longer height so a scrollbar appears.But I also read that this problem can be correct using a mask but I do not know what is the better way. Which do you recommend?
<mx:Canvas id="panelContentECG" width="100%" height="400" backgroundAlpha="0.5" styleName="miCanvas" borderStyle="solid" cornerRadius="20" borderColor="0xFCFE00" horizontalScrollPolicy="off">

I'm trying to draw a String inside a canvas. The text and the position of the String changes pressing differents bottoms. For doing so, I create TextFields which I added to a sprite which I added to a Canvas:
canvas.rawChildren.addChild(spriteNombres);
The first time everything works fine but when I press the bottoms,it does not refresh and appear the old textfields and the new ones.I cant remove the old ones, I try with removeAllChildren and also trying to delete one by one with removeChildrenAt. I do not know if I'm doing something wrong or maybe this is not the best way.
I also try creating bitmapdata and drawing in the sprite inside a rectangle.
var channelName: TextField = new TextField();
channelName.text = channelNames[displaySequence[channel]];
if (channelName.text != null) {

Basically I discovered its no problem at all to draw lines or shapes or whatever directly onto an mx:Text object using its graphics property (Text.graphics.lineTo, etc.). If just displaying that text, then any such drawn lines are displayed as well. However, if that Text object is used as a mask, then any drawn lines on that text object are merely ignored when the mask is rendered. And its hard for me to see the reason behind this, if anyone else is able to. I mean you're designating the Text object itself as the mask. It seems like any visual change to that text object should be part of the mask.

I want to dynamically add different items to thumbContent canvas and use scroller canvas to scroll. I see than the height of thumbContent bigger than 7977 it truncate from scrolling. So - I see the scroller canvas with empty space on top. Then I scroll to bottom - I see the content of thumbContent and at bottom scrolling I see empty space too.

I'm trying to skin a canvas with an image (which is essentially a custom border for the canvas). I've been trying the backgroundImage style as well as the borderSkin style. I can't get the image to scale to the full size of the canvas though. I was wondering what the best way to go about this is.[code]...

I need to to incorporate a functionality where the user can use his mouse to draw a rectangle by dragging his mouse over the canvas - much like the Rectangle Drawing Tool in the Flash Authoring environment. The requirement is something like a rubberband tool where the user can define a portion of a map by drawing a rectangle over it. The coordinates needs to be captured.

Just opened flash for the first time to find that the pen tool will only draw straight lines.It can still plot points and the lines will join up but curves are impossible.Is there some setting that disable drawing curves? I haven't found anything in the annoyingly-online files.

I would like to have a possibility, where a user could draw simple lines, but with exact length (5000mm, 3150mm, 3950mm etc).where a user could just click and see the lines. Together these lines would make a floor plan for a house. These lines don't have to have thickness, because it will be just a sketch where walls are located. After user has drawn the sketch i would need the program to generate a text file with coordinates of the lines.

I cannot get the lines to draw onto the top of the MovieClip box_mc.At this pojnt, my solution is to change the alpha of box_mc to 0. Now I can see my drawings which are under the box_mc but keep within the boundries of the MovieClip.Maybe my thinking is too concrete, but I was trying to get the drawing lines to stay on top of the MovieClip box_mc like it was a small drawing board.I have tried place a reference to the stage in various places and use addChildAt() in order to see f I can change the MovieClip's place in the hierarchy but so far nothing has worked.

I am trying to create a flash movie (AS3) that would allow the user to draw using his mouse but straight lines only. The user would click to set the start point of the line then as he moves the mouse around the line would move with the mouse until the user clicks again to set the end point. When the user clicks again a new line is created without deleting the previous one.

I have 4 coordinates from which i created a rectangle(using lines). I also created buttons dynamically. It works great for straight line. But when the coordinates generate diagonal lines im having a problem in making it go below the lines or fitting it inside the figure. See my pic for better understanding. I have also figured out how to rotate the button.[code]...

my requirement is that i want to dynamically draw lines on stage using actionscript only;
the end of each line should be the starting point of the next line. all lines will be of random different lengths, heading in random different directions...
but all line should stay in the bounds of the stage i.e. if the stage is 1024 X 768, lines should not go way out of these dimensions...

I am looking to create a drawing component on a site. that should be straight forward.the issue lies with the fact that I would want to detect any collisions say (4) and then attach MC's to the collision points.in a nut shell.can I get a trace of the drawn path on the stage?????from there I guess I can detect any positional similarities?

I made this one poor class that has a public function which draws with a single loop a shape with curveTo() function (I tested one option to draw straight lines with lineTo() and only curved lines with curveTo() function but in my opinion, that lineTo function where a bit slower, at least in my implementations of testin speeds).I sent to it four parameters (anchor points and the control points) as many times as there were some corners to draw and everything seemed to go well untill I checked which way is faster to draw single rounded rect. Flashs own way beats my version up with huge 120 m/s distance already in some 100 000 iterations. The format of data I tested to send to my class function to draw that goddamned thing were numbers in arrays, numbers in objects and numbers in my own class objects like linked list and the file that holds just four numbers included in arrays or linked list. And two separate arrays, one for anchor points and one for the control points, with just Point Objects were fastest (if I remember correct) way but still that 120 m/s slower than Drawing API in Flash.My function in the class where something like:
ActionScript Code:
public function drawShape(points1:Array, points2:Array, lineOn:Boolean = false, fillOn:boolean = false, lineThickness:Number = 1, lineColor:uint = 0, lineAlpha:Number = 1, fillColor:uint = 0xff, fillAlpha:Number = 1):void{[code]..........

I was screwing around one day and thought I'd make a little line-drawing-thing. Basically it just attaches movie clips and draws lines between them using the drawing API. That was the easier part. Now I though I'd take it a step further and add some curves. I tried but the attached file is the best I could think of.
square.fla is the original file
lineCurve.fla is the file in which I tried to add curves.

Right now I have it so that the user draws a line and I capture the points at which they begin and end the line. Then I delete that line (it is too sqiggly) and draw a straight line between those 2 points.What I would like to do is let the user draw lines as needed (ie arond other objects on stage) and then somehow smooth them out

I drew a line, and named it multiLinesHorizontal_mc (It's not on the Stage, but in the Library and exported to ActionScript3). Now I would like to use that multiLinesHorizontal_mc and bring it on stage (25 Horizontal Lines) with space between each row the gap should be 5.
