ActionScript 3.0 :: Flash Most Efficient BitmapData Grid Drawing With Alpha

Oct 14, 2010

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.

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] ) );
[Code] .....

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.

Flash :: Most Efficient Way To Overwrite Bitmapdata?

Jul 15, 2010

I have a bitmapdata object that is filled with n rectangles of a width of 1 pixel and of varying heights.

I want to run through a loop and remove the old rectangle and replace it with a different one.

Should I do something like reset the each bitmap column of pixels to a background color and then add the rect i want?

ActionScript 3.0 :: Changing Alpha Of A BitmapData?

Jan 11, 2010

I'm blitting a map onto the screen with tiles.. and the source of these tiles are BitmapData objects.I know you can change the alpha of a bitmap.. but I'm not too sure if it can be done on the BitmapData object itself.I want some tiles to have less alpha than others. Applying the alpha to the Bitmap.. makes everything on the current screen have an alpha.. but I only need one tile of it..

ActionScript 3.0 :: Using BitmapData For Drawing Graphics?

Jun 23, 2010

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?

ActionScript 2.0 :: Mx - Grid Effect With Alpha Fade?

I have the code below positioned on a keyframe in the main time line which gives me a grid effect using the instance 'cube' of the MC 'cube.

for (var i=0;i < 10;i++)


The effect i want though is for the reduction in alpha to stagger from instance to instance, whereas at the moment they all fade together. Is there a way of tweeking the code i already have to achieve this staggering effect or does the whole thing need re thinking.

ActionScript 3.0 :: 4 By 4px Stage Grid For Drawing Dots?

ActionScript 2.0 :: BitmapData Clear Pixels Or Set Alpha

Feb 26, 2008

What I have setup right now is one movieClip that is being used to be drawn into a BitmapData object. That bitmapData object is being drawn on the enterFrame and I am needing to clear it so it doesnt have the previous enterFrames information still stored in it, then once it is clear draw the current information. Is there a simple way to clear or erase all the pixel information in the BitmapData object?

If there is a way to set the alpha of the pixels I would really like to know how that is done as well. However, I want to change the alpha level of the entire BitmapData object, not just a few pixels.

ActionScript 3.0 :: Drawing A Transparent BitmapData Error

Mar 16, 2010

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:

bmdScreen=new BitmapData(viewWidth,viewHeight,true);


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.

Actionscript 3 :: Merging Two Bitmapdata Objects' Alpha Channels?

Aug 22, 2011

i have the following situation:

one drawing layer (graphics object with lineTo, etc.)

one png with an alpha channel (supposed to serve only as a mask)

now i want to be able to only draw lines within an area restricted by the png mask.

i am trying like this:

var bitmapData:BitmapData = new BitmapData( 320, 320 );
bitmapData.draw( drawingLayer );
bitmapData.copyChannel( maskBitmapData, new Rectangle( 0, 0, 320, 320 ), new Point( 0, 0 ), BitmapDataChannel.ALPHA, BitmapDataChannel.ALPHA );

now the borders get cut off fine, but i get a black background, since the drawing layer has an alpha between the drawn lines (and it should remain like this) and the mask bitmap has an alpha outside the shape. so naturally the mask's alpha replaces the drawing layer's.

i tried it with merge, copyPixels and also with just setting the mask property on the drawing layer (i set everything to cacheAsBitmap) but to no avail.


when trying to use a mask i tried it with

<s:BitmapImage id="mask" source="@Embed(source='...')" cacheAsBitmap="true" />

and also as

private const BodyMask:Class;
var maskBitmap:Bitmap = new BodyMask();

and assigned them to the mask property of a s:Group element (cacheAsBitmap=true) where the operations on the graphics object occured. i also tried reassigning the mask after each draw operation.

ActionScript 3.0 :: BitmapData's Draw() Method Also Draws Objects With 0 Alpha

Mar 17, 2011

I am drawing a flash sprite on a BitmapData using its draw() method. This sprite has some nested objects with 0 alpha, yet the draw() method draws them on the bitmap data.

I think it has to do with the color transform I am using, but I have no idea how to change it to achieve the effect I want.

The color transform is the following:

new ColorTransform(1, 1, 1, 1, 255, 255, 255, 255);

I am using these values in order for the Bitmap to have white pixels wherever the object was, and black where there is nothing. The draw() also draws my alpha = 0 objects in white as well.

ActionScript 3.0 :: Place Bitmapdata Drawing Over Content / Get Desired Effect

Apr 16, 2009

i 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

ActionScript 3.0 :: Drawing Arc Of Circle And Adding Alpha

Jun 5, 2010

I'm trying to construct an animation illustrating the angle of a circle.The user types in a value and the handle gets rotated on a timer tick. (Press Enter or the ndra-button to see the effect): Example So far so good.Now - my problem is when the rotation gets bigger than 360 degrees. I would like the arc's alpha to get darker, to see it draw upon the "existing" arc line. But I don't know how to do that and I can't find code for doing it, either.[code]The DrawingShapes.drawArc method comes from here.If anyone could point me in the right directon on how graphic updating works. I tried not removing the lineHolder from stage when it's updated, but that just made the line's alpha 1 instantly. I would like it to "gradually" get filled in when the arc exceeds 360 degrees.

Actionscript 3 : :Improving Slow Performance Of Drawing Application Using BitmapData.draw()?

May 27, 2011

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.

Flash :: Flex Data Grid: Check Whether Item Renderer Displays Last Row In Grid

Feb 3, 2012

I'm currently working with the OLAPDataGrid component and got stuck at a relatively simple task: I want to style the last row of the grid differently from the rest, so my cell item renderer needs to know whether he's rendering the last row with content in the overall grid, including those rows currently not rendered because they are outside the visible grid space. AdvancedGridListData's rowIndex property only gets me the row index of the renderer relative to the range of visible grid rows, i.e. when I scroll down the grid, a data item with an index greater than 0 gets the rpw index = 0.

I'm using the bitmapData.scroll() function. Now unless I clear the screen each time the character moves, it's going to leave ghost images of the border of the screen, like this picture: zanzlanz. tumblr. com/post/18857712784 If I clear the screen each time, then it generates a lot of lag (because it has to repaint the objects again). I'm a bit lost on how I can scroll without leaving streaks of the side of the screen and without repainting the entire screen.

More Efficient Keyframe Animation In Flash CS4/5?

Dec 12, 2010

I'm doing a lot of keyframe masking of vines/flowers for a project I'm working on, and it looks really good but is, of course, very time consuming.I'm curious if there's any techniques/tools for making these animations faster, and more importantly making them more editable later. I'm afraid I'm going to keyframe out entire sections of animation only for the client to say "Looks great, but can you speed it up just a touch?" and I'll have to rebuilt it all from scratch again.
