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 am trying to draw in flex in all four quardrants!i mean i have a 2-d plane,and i have values that i have calculated now i need to draw these in a plane! i tried the plotchart, but it only works in first quadrant,it doesnt take negative values!
View 0 RepliesI'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 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.

View 2 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'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] ) );
[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.
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.
check if a negative number is less than another negative number. The if condition logic seems to be in order as far as i can tell but it doesent work for some reason :
Code:
public function minuscheck(testnumber:int):void
{
if (testnumber < -1)

btw, first I used assigned thumbContainer as the mc argument (outside the loadThumbs() function) and it worked but not exactly what I wanted... because I thought it is supposed to update when the movieclip is animated but it actually didn't... when I use a scroller, only the thumbs that are first loaded to the stage get the reflection..
I've been using BitmapData.copyPixels() to draw graphics onto a canvas (Bitmap).I need to rotate the resulting graphics without the use of draw() because it's vastly slower.How can I rotate the target graphic? I'm assuming that there might be a formula or library that I can use which will first reorganize the pixels that make up a graphic based on an origin (point) and radians.I'm pretty certain that I'm not capable of creating such logic, so if there are any known libraries that do this, that would be awesome.I'd like to achieve something similar to XNA's SpriteBatch.Draw() method, which accepts rotation as its 5th argument.
