I would like to extract the most common color of a bitmap. My first idea was to do this by looping through the bitmapData and extracting every pixel color and storing it in an array. But the function has to be as light as possible so my question is; Is there a more lightweight approach to achieve this? The function is used to extract background color of a Bitmap.

tabBar.getChildAt and setStyle

View 8 RepliesI'm cutting my teeth in actionscript 3 on a game that has a character running through a world. So, I have set up my Hit Testing by using the bitmap data hit test method, since I figured my world is going to be destructible - it'd be nice to update the level and then redraw it and have the character interact with the new change. (That works beautifully) I am however; a bit confused as to how I have my hit Testing set up. I've been messing around with it, and it works for now - but I'm not sure why.. currently, I have a character set up by using a class I built and using a series of animations I created. So, this character has a walking and falling animation, etc. This is a movie clip.
Then there's a bitmap 'emptyBitmap' with bitmap data created - however; I never really added this as a child to the character. This is sized to the dimensions of my character. My level is created as a movielip, then it's drawn to a bitmap - when the level movieclip is changed, the bitmap redraws, and that's how this updates.

I want the user to be able to click a picture and the background of the swf will change to the color of the pixel where the user clicked.
View 2 RepliesI am working on a project that involves custom vinyl lettering. I have the a swf that loads images to an image scroller which can then be drug onto a stage and scaled or rotated. What I need to know is if and how I can change their color using the color picker component.
View 23 RepliesApparently, in order to make a bitmap transparent, one has to convert it to 256 colors from 24. I'm not sure if Flash puts it in 24 or 256, but because I can't create a transparency when using Bitmap() in my code, and from what I see displayed on the screen, it would appear that it uses 24 colors. Perhaps this is to keep things light. Nonetheless, is it possible to convert it to 256 colors?

View 1 RepliesI've been messing around a bit with some low-level bitmap manipulation and having been creating some various color matrices to apply to bitmap data to add "filters" (for lack of a better term).I have seen a number of tutorials online in C# and AS3 about applying various color matrices to bitmaps, but was curious if anyone simply had a collection of these color matrices that map to specific filter styles (black and white, sepia, etc.).

View 2 RepliesI want to find a script that compares colors in a given region and gets the closest websafe color.I found the color sampler class that returns the average color.

View 0 RepliesThis may be stunningly simple (It certainly was in Director), but I just can't work it out in flash. I basically want any pixels of a certain color on an imported 24Bit (no alpha) Bitmap to appear transparent using AS3 (like a simple color mask, any black pixels are not drawn). threshold() only seems to work correctly on 32Bit BitmapData with alpha channel so the only way I've found so far is this craziness..

In Photoshop there is a tool that lets you adjust the levels of an image. I'd like to be able to do the same thing. I've seen examples online that show the levels but they are for each individual color channel (red, green, blue or alpha or CMYK) but not a combined view like in Photoshop Input Levels (see below).Also, as a bonus is there a way to find the best shadow and highlight input level settings, basically the settings the Auto level button determines?Update:I think I'm closer but I'm not sure. Here is the method I pieced together. The first image is my results and the second is Photoshop results both analyzing the Google logo:Update 2:Ok I think I got it. The code is below. It's mostly working all the time, mostly. Additional credits:Photoshops results:

I'm building a game that will be using a bitmap to render the environmental scene. the bitmap is a black image with little green squares to indicate x,y place holders for tree locations as i render the scene. i was thinking of looping thru each pixel to find green pixels but this proves to be a performance hit when the image is 2500x2500. then i found what i thought was a handy little method called BitmapData.getColorBoundsRect() that will locate the position of the green box. It does this but it returns me 1 rectangle of all the green boxes inside.
View 2 RepliesI have a bitmap with many colors on it. When the user clicks each color needs to trigger a different method. However, I have no idea how to check the color value of the selected bitmap. I can create a new sprite and check the value of that fine through bitmapdata.getpixel() but when I need to actually check the actual bitmap I cannot get it to work.

Instead of using the RGB mode, I'd like to use Bitmap fills.
i have found a beautiful water effect made in as3. The effect is available to download on the website below.I am trying to change the fill of the water (that is blue or any color that you pick).The original code fills the water like this:
Code:
public function renderWater():void {
shape.grapics.clear();
shape.graphics.beginFill(0x006699);
shape.graphics.lineStyle(0, 0x000000, 0);

I tried to follow the instructions on the beginBitmapFill help, but i am receiving the water with no fill.

I need a Bitmap to make a color map inside certain symbols. What I do is import the png file and export it to as3. After that I drag and drop it inside the Symbols that need it in the correct position. What I need to know is how to get a Bitmap child inside a symbol that belongs to a class if I can't set the instance name of that Bitmap. for ex: a Symbol of the class MyClass has an img exported as Class MyBitmapClass and Base Class flash.display.BitmapData. I want, through as3, to get this MyBitmapClass object.
View 1 RepliesI've created a prototype that will copy the pixel data from a movie clip then create a JPG image from it via PHP. It works perfectly. But when the MovieClip (called mcImage) contains a Video Object loaded with a streamed FLV, it won't copy the pixel data to the Bitmap object. The image generated is white. Here's a sample code:
var oBitmap:BitmapData = new BitmapData(nW, nH, true);
var oMatrix = new Matrix();
var oColorTrans:ColorTransform = new ColorTransform();

View 9 RepliesI have made a little drawing program for my daughter, and I have worked in the ability to save and load images that you have made. It's a simple line drawing thing, but she's 3, and it works.Whatand I'm still new with Flash and AS3) is that I can "addChild" to put the jpeg on the stage, but it's on (or over top of) the drawing area. That means that when I start to draw, I don't really add to the picture, instead, it's drawing behind it. I used the line drawing tutorial as the basis for this little app, the basic code is :
Code:
public function DrawMain(){
graphics.lineStyle(theLine,0x000000); //default to black lines

View 6 RepliesI'm trying to create sort of an eraser to remove sections of a bitmap on stage.
I have achieved this by creating a MovieClip in flash that is a circle and exporting it as a Class called Hole.
Now I use this MovieClip to erase a circle section of the image using the following.
var mat = new Matrix();
var ct = new ColorTransform();
var hole = new Hole();
mat.translate(x,y);
image.draw(hole, mat, ct, "erase");
Now what im trying to do is scale the size of the circle depending on a certain variable but no matter what I try the scale doesn't seem to change and. The size seems to stay the same as I drew it in Flash. I tried adding the following line
hole.width = hole.height = size;
I even created a class file called Hole and the size as a parameter
var hole = new Hole(200);
This didn't work either it still appeared to have the same size. I have even tried altering the scaleX and Y values with no success.
I am adding a bunch of bitmap data (images) inside a canvas bitmap (using copyPixel) which is added to the stage (addChild(cavasBitmap)) how can I remove a bitmap data from a canvasBitmap?
