having a problem while drawing a complex combinations of TextFields into BitmapData in as3,The problem happens when i change the parent's (x,y) or (width, height) and the drawn object got a bad effect like left blur.[code]
View 3 Repliesi am creating a very simple particle system. My only issue is trying to create a blurry trail effect on the particles in motion. I started by creating a large bitmap container, and applying a colormatrix filter and a blur filter . It seems to do the trick , but the issue now, is i have to make this container cover the stage, which has a two unwanted a effects:
-it's slower
-it covers all the content beneath. Perhaps my approach to creating trails is wrong?
i can post the whole class, but before i litter this post with long lines of code, is there a way to place a bitmapdata drawing over content and still get the desired effect. NOTE, if make transparency false in the bmdata, i loose the effect
I'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?
what i need to do is basically a motion trail on a bitmap.
I want to continuously draw a bitmap onto itself while previous versions are faded into the background, similar to a smoke type effect.
I wanted to use the well known method for turning your vector graphic into bitmaps.Ie, something like:
Code:
var bmd:BitmapData = new BitmapData(src.width, src.height)
bmd.draw(src);

I have a huge background bitmapdata with a corresponding grid. I'm trying to draw the two parts onto a different bitmapdata, but for some reason, the bitmap for the grid is overriding the bitmapdata of the background that is being drawn first. The grid seems to be making the entire third bitmapdata transparent for some reason.
My code for creating the background and corresponding grid:
Code:
viewWidth=stage.stageWidth;
viewHeight=stage.stageHeight;
bmdScreen=new BitmapData(viewWidth,viewHeight,true);
[Code].....
I want to draw a grid on top of the background I have. For some reason, the grid is making the background underneath it transparent.
I have the following display hierarchy:- - container- - - objectI need to draw 'object' to a BitmapData instance which matches object.getBounds(stage) rectangle area. So the first part is easy:
ActionScript Code:
var rect:Rectangle = object.getBounds(stage);
var bmp:BitmapData = new BitmapData(rect.width, rect.height, true, 0x00000000);

I parse an xml file that his content is:
Code:
<?xml version="1.0" encoding="utf-8"?>
<operators>
<operator><name>OPerator1 </name></operator>

I display the name of operator in a TextField after parsing the xml file my problem is to loop through this different TextField with a fade effect.
I'm getting this one: Error #2123: Security sandbox violation: BitmapData.draw
while I try to draw the image of a video from a rtmp server onto a BitmapData object. The workarounds I've found all apply to a SWF file being loaded from another domain. This involves having logic in that file.However, I see no possibility to place logic into the video and hardly have access to the (WOWZA) video server of which there are multiple and to me unknown ones at forehand due to the CDN's load balancing nature.
I'm looking for the most efficient possible way of drawing an 8 x 4 grid (960x600 total size). Each square of the grid has a variable alpha and the grid is redrawn every enter frame. The problem is my application is doing a lot already and I'm looking for the most efficient way to execute this loop 32 times (possible more in fact) per frame without overloading processor.
Code:
private function init():void {
var dimensions : Array = [ 0, 0, 960, 600 ];
var gridRaw : Array = [ 8, 4 ];
var stageRect : Rectangle = new Rectangle( Number( dimensions[0] ), Number( dimensions[1] ), Number( dimensions[2] ), Number( dimensions[3] ) );

I'm under the impression there could be better ways of drawing the shapes straight to BitmapData without using Sprites, or maybe I'm doing something wrong about memory usage as I can see memory going up and down in a cycle.
I am using a custom Flex skin to create an active blur/frosted glass effect on the background of floating Panels, TitleWindows, and other containers (similar to http:url....). There is a background image in the Application skin, and potentially any number of other components above and below the active blur component. Here's some relevant code within the skin:
public static const BLUR_FILTER :BlurFilter = new BlurFilter(16, 16, BitmapFilterQuality.HIGH);
private var _bitmapFill :BitmapFill = new BitmapFill;
private var _matrix :Matrix = new Matrix;[code]....
Unfortunately, the performance of this when the component is being resized, and especially when moved, is poor. There is noticeable drag delay and overall slowdown, and this is with only one popped-up TitleWindow in the test application. There is especially poor performance when components inside the TitleWindow are changed (button hover states, etc.)I've attempted to optimized a little bit by avoiding reinstantiation of the blur filter, bitmap fill, and matrix, but this has had little or no effect. I removed the blur at one point, just drawing the Application to a bitmap, and the performance is still poor, so it's clear that it's mostly the BitmapData.draw() call.
I've read about using scrollRect and cacheAsBitmap, but I'm not sure where to apply these properties (or other optimizations I'm not aware of) within the Application or its components.
Can anyone help me manipulate bitmapdata to get a similar effect to the one shown here:URL...I have converted the contents of a movieclip into bitmapdata but haveno idea how you manipulate sections like that above. .

View 5 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 2 RepliesIf I create a simple Textfield and place it on the stage, it looks good.If I take the same Textfield, and paint it into a BitmapData (first putting the Textfield into a Sprite so I can paint it), the resulting BitmapData is not the same, pixel for pixel, as the original textfield on the stage.refer to the attached image for a zoomed in view on the differences in the aliasing. What can I do to keep the two pixel-for-pixel identical?

I would love to get some help or advice on how to create an effect in a drawing application. I want to build a drawing application, which is not that difficult. I've found several resources on these type of applications. What I want to do is "merge" 2 examples that I've found. This drawing application makes sense to me and I feel I can modify it to my liking. (sorry in advance I cant post links)

I want to end up with the following effect. Bitmap pencil quickly moves accross the canvas diagonally and reveals an image. The image itself is drawing so I kinda want to make the illusion that the pencil draws whatever is on it. I don't want the pencil to follow the actual line in the image just to ask like a mask and quickly reveal the picture. So I was wondering if there is any cleverer way to achieve this, instead of animating everything manually

View 1 RepliesI want to create the drawing effect in Flash that many of us have seen on various websites.URL...I have an object already made in Fireworks. It's just a simple rounded rectangle with a 10 pixel stroke. I'm looking to draw the mask which in turn will give the impression to the user that the object is being drawn (because masks work in reverse).Right now, I have a version already done with a frame-by-frame slow erase of the mask. When played, it makes it look like the rectangle is being drawn. The problem is that it's just too shaky and jumpy. I need a more fluid animation which, like most things, can be done much better in ActionScript. I saw the Drawing API tutorial on Kirupa.com, but it doesn't show how to animate it and I definitely don't know enough AS to do it myself.
View 7 RepliesI want to draw text to a bitmapData and allow it to be rotated but rotating the text makes it disappear :(The code I am using resembles something like this :
var tf : TextField = new TextField();

When I'm building an composite animation, I'd like to specify the components as fractions of the parent, like so:
<s:Sequence id="example" duration="2000">
<s:Fade alphaFrom="0" alphaTo="1" duration="10%"/> <!-- not legal -->
<s:Scale scaleXTo="2" scaleYTo="2"/>
[Code]....
Is there a more declarative way to accomplish this? In the latter case, for instance, can I at least replace the variable slideTime with a direct reference to the parent's duration?
I have 1 MC with another MC inside it. That MC is triggering a function that is called for when a third Mc is in hitTest wich affects the first MC. How to get make the function to effect the parent of the triggering MC?
View 1 RepliesI'm trying to do a cross-fade effect for my gallery. To do that, I'm using two movieclips, one that holds the image currently displayed, and another one that holds the image that should be displayed next. When the coming image is loaded, the cross-fade effect should happen, the container that holds the image that was on stage should be cleared out, then the image in the other container should be displaced to the former container.
Here's my code so far:
function loadFirstImage():void {
imageLoader = new Loader();
imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, addFirstImage);
imageLoader.load(new URLRequest(myImages[0].url));
currentImage = new MovieClip();

I have a panel with a button in it. Clicking on the button will direct the panel to state "State2" adding another two buttons into the panel. During the state change, I want the panel to resize first and then show the newly added two buttons, so I applied transitions onto the state change.
My question is:
If I put the two buttons within a HBox directly under the addChild tag, it works fine. However, if I create a new component with the same code (HBox with two buttons in it) and then add the new component to the panel (Comp in the code commented), it won't show the resize effect.

This doesn't work, Does anyone know how to do it?

View 3 RepliesI have this function:
public static function cloneDpObj(target:DisplayObject):Bitmap

to clone target displayObject (MovieClip or Sprite) and return Bitmap Object.
It can get bitmap from the target object, but it seem don't get all the area of the image.
By give the width and height of target object, but the target object in design was applied by Glow Effect, so my question can we get the all view of bitmapdata from a displayobject?
I have a MovieClip that has a Dynamic TextField: let's call the instance of the field txtName. I want to set the text field on the fly for txtName, so I add a little ActionScript (3!) that does it nice and easily: txtName.text = "Foo";reat. Now why isn't it working when I try the same thing from a parent MovieClip which contains the MovieClip that has the dynamic text? Example:Child MovieClip with TextField ActionScript 3 in Frame #1:

function SetText(str:String):void {
txtName.text = str;
