View 23 RepliesProfessional :: Convert Bitmap To 256 Color?
Sep 3, 2010Apparently, 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 RepliesC# :: Collection Of Various Color Matrices For Bitmap Manipulation?
Feb 6, 2011I'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 1 RepliesActionScript 3 :: Most Common Color In Bitmap (Data)
Mar 26, 2012I 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.

Jun 20, 2010This 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..

Flash :: Get And Display The Levels On Color Or Bw Bitmap Image?
Apr 26, 2011In 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.

ActionScript 3.0 :: Locate Multiple Positions Of A Specified Color In A Bitmap?
Aug 11, 2010I'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.

ActionScript 3.0 :: Get Bitmap Child - Make A Color Map Inside Certain Symbols

View 2 RepliesActionScript 3.0 :: Bitmapdata.hitTest - Bitmap 'emptyBitmap' With Bitmap Data Created
Feb 3, 2009I'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.

ActionScript 3.0 :: Use The BitmapData Property Of A Bitmap And Pass It To The Constructor Of A New Bitmap Object?
Aug 20, 2009I 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),

View 2 RepliesActionscript 3 :: Bitmap Too Big - Limitation Is In Bitmap And Loader?
Mar 30, 2011In AS3, I am loading a png from a zip file (nochump's zip library through ByteArray to Loader). The png can be up to 45k pixels wide but only 120 tall. This creates a problem in flash, as images can only be ~8000 pixels wide. A possible solution would be to split the images into 6 columns somehow. This would probably need to be done in the ByteArray state, because the limitation is in Bitmap and Loader.
