ActionScript 3.0 :: FXG To SVG - Convert Color Offset Changes To Matrix Filter

Apr 19, 2011

I'm trying to convert a simple FXG to SVG. The conversion is pretty much straightforward, but I'm encountering a color manipulation problem. The FXG have a base shades of gray path, and I apply a different color transformation on subsequent use of this path for other shapes.

Here the FXG color transformation (equivalent to colorTransform) :
<ColorTransform redOffset="-255" blueOffset="25" greenOffset="56"/>

How can I convert this color transformation (even the negative offset) to something SVG understand? I only need the color offset changes, no multiplier or alpha. I think it could be achieved with <feColorMatrix> (look like this SVG filter work like the AS3 ColorMatrixFilter) but I can't find how. How I could convert those color offset changes to a color matrix filter ?

ActionScript 2.0 :: Color Matrix - How Can Apply This?

Apr 14, 2008

I'm building a website and I have a constant moving background that is red. Sometimes I need to change the color of the background. Now I Don't want to load new movies! Instead I would like to use the adjust color filter to change the color of the background. Now through research I have found out that you have to use the color matrix. Here is the code

import flash.filters.ColorMatrixFilter;
var myMatrix:Array = [1,0,0,0,0, // Red
0,1,0,0,0, // Green[code]....

My question is how can Apply this so I can fade it in? I assume I use an onEnterFrame to add it but how do I alpha it? It's kind of like this tut but not for a button.

Flex :: Create A Color Glow Filter With Duration?

Apr 13, 2011

I need to highlight a button's border, so I have created a glow filter like this:

<s:GlowFilter id="GlowFilter1"
color="0xD9D919"
blurX="30" blurY="40"
alpha="1"
/>

The problem is that I don't know to remove the effect. The effect remains in the opction as it was highlighted. Thus, I'd like to set a duration, or something that removes the effect I create.

Actionscript 3 :: Add Bevel Filter On MovieClip After Changed Its Color?

Dec 13, 2011

When I change color with

var blue:ColorTransform = new ColorTransform();
blue.color = 0xFF00B8E7;
MovieClip.transform.colorTransform = blue;

[Code]....

How can I add this bevel over or on the new color that I changed?

It seems like that the bevel takes all colors as the new color that I changed, not taking the one I specified

myBevel.highlightColor = 0xFFFFFF;
myBevel.shadowColor = 0x000000;

ActionScript 3.0 :: How To Add Bevel Filter On MovieClip After Changing Color

Dec 13, 2011

When I change color with
var blue:ColorTransform = new ColorTransform();

I add this
var myBevel:BevelFilter = new BevelFilter();
myBevel.type = BitmapFilterType.INNER;
myBevel.distance = 3;
myBevel.highlightColor = 0xFFFFFF;
myBevel.shadowColor = 0x000000;
myBevel.blurX = 5;
myBevel.blurY = 5;
MovieClip.filters = [myBevel];

The result is, only color changed. How can I add this bevel over or on the new color that I changed? It seems like that the bevel takes all colors as the new color that I changed, not taking the one I specified
myBevel.highlightColor = 0xFFFFFF;
myBevel.shadowColor = 0x000000;

Actionscript 3 :: Filter A Specific Color From A BitmapData Object (or Byte-array)?

I'm looking for an efficient way to filter a specific color from a bitmapData object in ActionScript 3. Currently I use a loop with readByte32(). This takes about a second to process which is unacceptable. I have been trying to get paletteMap() to work but so far haven't been able to grasp its API (any truly useful links? Google has failed me...). Here's my current logic, which I want to improve:

ActionScript 2.0 :: Matrix Algebra And Matrix Inverse?

Apr 5, 2003

Has anyone here ever developed a function (or general library of relevant functions) that will allow one to find the inverse of a matrix? I've searched the forum archives, as well as the internet more generally, but haven't found anything. If anyone has some leads, I hope you'll pass them along.

If I don't hear anything within the next few days, I might try to develop something on my own, but I'd hate to do so if someone has already done the dirty work.

A solution to this problem would be very useful for 3-D work or anyone doing mathematical programming more generally.

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 3.0 :: Convert XML String To Hexadecimal Unit Color

Apr 14, 2008

I have an xml file containing color values to be applied in a series of shapes in my swf. However, when I try to assign the values, it doesn't work, it recognizes only a string and assigns the value 0 to the colors.

Code:
//my_color.xml
<color_list>
<color_1>0xFFBB00</color_1>
<color_n>0xAA33FF</color_n>
</color_list>

The xml is then parsed into a variable called xmlColor.
//.fla
var c1:uint = xmlColor.color_1;
trace (xmlColor.color_1) //0xFFBB00
trace (c1) //0

ActionScript 3.0 :: Ludicrous HtmlText Offset?

Aug 4, 2009

so I'm working on an app requiring me to lay some simple HTML as multicolumn text, and hacking around w/ g.skinner's old regexp method of reflowing as3 TextFields. I'll be happy to share this code if I can get it working. No desire to get into screwing with text.engine at this point, and this has to be back compatible to FP9 anyway.

So I'm back-and-forth parsing from likely break points to determine if we're in a tag here, and jump ahead to the end of it if we are. The ridiculous issue I'm up against is simply that there doesn't seem to be a TextField method for getting the htmlText offset -- NOT the visible text offset -- of a character. Is there a way to do that?

Actionscript 3 :: Strange Offset In Flash?

Dec 14, 2011

I need to check (for my own good reasons) whether the cursor is located within the bounds of a particular object. I'm using a simple code to do this...

if(mouseX > hsSlot1.x && mouseX < (hsSlot1.x + hsSlot1.width) && mouseY > hsSlot1.y && mouseY < (hsSlot1.y + hsSlot1.height))
{
//My code
}

This, theoretically, should work perfectly! However, there is an offset (and one I did NOT set, mind you!) of about 16 between the hsSlot1's visual position (where it appears to start on the screen) and hsSlot1.x. There is a similar offset on the y axis, but I haven't measured it yet.The only thing I can think of for this is that hsSlot1 is an instance of a button (one with only one state at that) that was scaled to fit. However, I don't think that is it, because the numbers show that the entire object is merely offset at its current size.

ActionScript 3.0 :: A Gradual Offset Of A MC (using Loops)?

Jun 14, 2010

im trying to actionscript a simple animation where a combination of MC's move towards areas on the screen triggred by mouse events.What would be the best way of gradually ofsetting a MC, with the control to stop them with further mouse events.I have used tweens (example below) but i need to be able to stop them mid tween, i have tried using if statement to stop the clip but i cant seem to overide the tween.I have limited experience but im guessing a time based loop that i could supply an if statement withbooleons would be my answer. Are time loops possible with actionscript 3.(my thinking is(mouse event. start time based loop -offseting MC- Mouse Event 2 stops loop with if. )

tween example i used
(function moveToLeft(event:MouseEvent):void {
xMovement = new Tween(walkMC, "x", None.easeOut, walkMC.x, mouseX, 8, true); )

ive found the timer class, i should be able to make summit work with this

ActionScript 2.0 :: Center Offset From Edge?

How do I figure out that the left edge is now at -111px, and the top at -52, and the right at 12, and the bottom at 334?

Or what if they draw it so the left edge is at 56px and the right edge at 583?

Essentially, I want to determine the center of my artwork, wherever it is relative to the center of the MC

Flex :: Handling Timezone Offset?
