C# :: Collection Of Various Color Matrices For Bitmap Manipulation?

Feb 6, 2011

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.).

ActionScript 2.0 :: BitmapData And Transformation Matrices - Shift The Newly Created Bitmap?

Jan 29, 2007

I've started getting to grips with using the BitmapData class and a Transformation Matrix in the hope that I can start making some interesting image effects. However, at the moment Im having trouble figuring out how to shift the newly created bitmap so that any scale transformations are applied from the center rather than the top left corner. See here for example: [URL] The flower on the left is the original, the flower on the right is the new image created using "bitmapData.draw()". It has been scaled up to twice the size, but I want this to happen from the center of the image.

ActionScript 3.0 :: Color Manipulation Class Of A Series Of Objects

May 1, 2009

I am trying to make a class that will allow me to manipulate the color of a series of objects and I�ve gotten this far with ColorMod.as which does this manually. I would like to be able to somehow generate a series of ColorTransform objects such that I can manipulate their parameters (particularly redOffset, greenOffset and blueOffset) while I am generating them, and then push them into an array that can be accessed by another class. I can do this manually as per the code below, but I would like to be able to do it using a for loop as per the pseudocode I put in the constructor below.

Professional :: Convert Bitmap To 256 Color?

Sep 3, 2010

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?

ActionScript 3 :: Most Common Color In Bitmap (Data)

Mar 26, 2012

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.

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..

Flash :: Get And Display The Levels On Color Or Bw Bitmap Image?

Apr 26, 2011

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:

Levels method:

ActionScript 3.0 :: Locate Multiple Positions Of A Specified Color In A Bitmap?

Aug 11, 2010

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.

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

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.

Flash - Multiple A Vertex By Two Matrices?

Mar 28, 2011

I'm trying to understand molehill and would like to multiple a vertex by two matrices, say:

output = theVertex * scaleMatrix * rotationMatrix

Im guessing my vertex shader would look something like:

"m44 vt0, va0, vc0
" +
"mul op, vt0, vc1
";

And i would set the matrices with

context3d.setProgramConstantsFromMatrix(Context3DProgramType.VERTEX, 0, scaleMatrix);
context3d.setProgramConstantsFromMatrix(Context3DProgramType.VERTEX, 1, rotationMatrix);

But its not working.Im aware that i could multiple the matrix before putting on the shader, but i am trying to understand AGAL.

ActionScript 3.0 :: Collision Detection - Rotation And Matrices

Nov 23, 2009

I am using Corey Oneil's collision detection kit, but I am having a problem with rotation. In my code I have:
myItem.rotationY = 180;

However, during a collision detection, having it rotated like this causes an error with this line:
transMatrix1.concat(currentObj.parent.transform.ma trix);
The error is simply "Error #1009: Cannot access a property or method of a null object reference."

I have not really worked with matrices and rotation. Do I need to make a matrix rather than just doing the rotationY or should I change something else? I cannot manually change the movie clip because it throws off the animation and armatures.

Actionscript 3 :: Reordering An Array Collection Based On Another Array Collection Hierarchy?

Sep 16, 2011

I have an array, crewPositionsAC that contains a list of position abreviatations - EP, PR, DR, WR, and so on. These positions are read in through an XML file each time my flex application loads. Also being populated from an XML is a project. Within a project, there are positions (a student assigned to a type of position listed within crewPositionsAC). These positions are not necessarily in the correct hierarchy order dictated by crewPositionsAC. I have all the positions within an ArrayCollection (positionsAC) with the following structure:

positionsAC (arrayCollection)
[0] = Array
[0] = startOffset
[1] = numDays

[code].....

Then, the user can click a button to add another position. When the "Add Crew Member" button is pressed, the user is presented with a list of possible positions to add. Currently, I simply add another array to positionsAC. This results in the recently added crew member to placed on the bottom of the list. I need to take positionsAC and reorder it based on it's [2] item (role) based on the hierarchy defined in the crewPositionsAC. crewPositionsAC has the following structure:

crewPositionsAC:
[0] = EP
[1] = PR
[2] = DR
[3] = WR

* continue until all possible position types are listed

Matrices Exist On Vertex Registers Other Than Vertex Constants In AGAL?

But never seen a matrix in any other types of registers (temporary or attribute).Would there be any way to copy a Matrix vertex constant to a temporary register, and then manipulate individual fields of that Matrix temporary register (ex:for the rotation), with other supplied values (vertex attributes or other constants)

ActionScript 2.0 :: File Manipulation With PNG's And JPG's?

Oct 3, 2006

Using AS2 or 3, is there a way to create my own file format? I would like to create a game.And when users play the game, they can create a GAME-SAVE-FILE.So, let's say that player 1 is playing... He get's to level 22 and has to sign off.He clicks save my GAME-SAVE-FILE to my computer.He names the file MyGame and saves it to his desktop.So now on his desktop he has MyGame.gsf. Next time he visits, he can click on UpLoad My Saved Game.He selects his previously saved MyGame.gsf And bammo... all the information was stored in his file and now he can play on.

I need to know how I would put together the format for my own file-type / extension.I need to know how I would access, write, and edit my own file-type / extension.Since Flash can do this type of File Manipulation with PNG's and JPG's.So surely it can be done with any desired custom format.

Why is that? Shouldn't it print 0x65ffff or do i need to do some type conversions?
