ActionScript 3.0 :: Knock Out A Single Color From A 24Bit Bitmap?
Jun 20, 2010
This 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..

Requirement: Create single very large bitmap data which contain some 30 PNG images loaded and for each image it should have some text. Images and text are loaded dynamically (AS2 code. Images are stored in a remote server). The bitmap data display should show 8 images at a time and corresponding text. We can see rest content by scrolling (kinetic scroll is implemented). How can I go for it?Some questions:Is there any limit for size of bitmap data ( As per link there is restriction on the height of the bitmap we can create in AS2 (max value is 2880 which is not enough for some 30 element list If we create individual bitmap data for 30 individual PNG files, we find some jerks in scroll. How can we have smooth scrolling?

I was just wondering if there is a way to simplify this code. I have 3 identical movie clips and I use actionscript to alter the color to the same color. Right now I use 3 different colorTransform variables. Could I just use one since its all the same color? How would it look like.
So far, naming all the movie clips the same instance name did not work. Is there a better way?
Code:
var color1:ColorTransform = button1.transform.colorTransform;
color1.color = 0x99628B;
button1.transform.colorTransform = color1;

i'm trying to create a unordered list in Flex. My issue is that within each line, i want the word NEW to be a different font color and different font size from the rest of the label text. I am unsure of how to do this INLINE within the label component.
<s:VGroup fontSize="15" color="#ffffff">
<s:Label text="u2022 NEW Invite your friends!" />
<s:Label text="u2022 NEW Features coming soon!" />
<s:Label text="u2022 NEW Invite your friends!" />

Apparently, 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?

I'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.).

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.

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.

I 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.

shape.grapics.clear();
shape.graphics.beginFill(0x006699);
shape.graphics.lineStyle(0, 0x000000, 0);

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.

i have a button, with instance name lightblue_color. I am assigning a color to its color field like this: lightblue_color.transform.colorTransform.color = 0x65ffff; then i am adding an eventlistener to the button like this: lightblue_color.addEventListener(MouseEvent.CLICK, ChangeColor); Then, in the function: public function ChangeColor(evnt:MouseEvent):void {trace(evnt.target.transform.colorTransform.color);} It prints 0. Why is that? Shouldn't it print 0x65ffff or do i need to do some type conversions?

I'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 know the topic of "duplicating" movieclips is a hot issue with the new virtual machine. Luckily, I understand the implications. I only am [currently] interested in duplicating a Bitmap. See, I load an image from an URL using 'flash.display.Loader.load', which is a non-blocking operation in Flash Player.However,I may use multiple copies of the loaded image (which is reported to be a Bitmap, naturally) in the display list at the same time.Hence, I naturally do not want to load the image from an URL every time, because I don't want to wait for a non-blocking call to complete. Nor do I need to - I mean one copy is already loaded, so it should be possible to just "duplicate" it, right?
My idea is to do use the bitmapData property of a Bitmap and pass it to the constructor of a new Bitmap object. I have not tried the following in action, but I want to hear whether any of you did and if the following would not work, what would:
Code:
var original_bitmap: Bitmap;
var copy_of_original_bitmap: Bitmap = new Bitmap(original_bitmap.bitmapData);
LiveDocs mention that the BitmapData being passed to a Bitmap constructor is "being referenced", which to me might suggest it cannot be used twice? There is also the BitmapData::clone() method, which I am not sure is applicable here or not.I know this is a lot of talk instead of just trying this out, but I test so much Flash Player code daily just to see "what works" (which should be documented instead by Adobe),

I'm working on a game, and to keep performance good, instead of addChild'ing 50 new sprites to the stage every second, I decided to have each player draw to their own bitmap, and then to the 'master' bitmap. This introduces an issue though: the second player would override all data the first player has put into to bitmap...My basic debugging proof of concept:
