[Flashcoders] bitMapData - function optimization
Hello Hello,
Just wondering if anyone has any tips or ideas on optimizing this function,
as its really slow.. Basically, it creates an inverted alpha mask from a
bitmap by going through every pixel in the bit map.
Here is the function:
code
private function createInvertedMask() {
var w:Number = mask_bitmap.width;
var h:Number = mask_bitmap.height;
var r:Number = 0;
var c:Number = 0;
var v:Number;
for ( r = 0 ; r w ; r++ ) {
for ( c = 0 ; c h ; c++ ) {
v = mask_bitmap.getPixel32( r, c );
if ( v == 0 ) {
mask_bitmap.setPixel32( r, c ,
0xFF00 );
} else {
mask_bitmap.setPixel32( r, c ,
0x );
}
}
}
}
/code

[Flashcoders] Accessing SVN from JSFL
Hi List I am hoping to create a custom Flash panel which can interface with Subversion. Is it possible to execute external apps, or command line access from JSFL? Thanks Jake ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

[Flashcoders] descriptor file probs stops AIR publish
Trying to use AIR, Wasted six hours yesterday. Tried tutorials, samples form the web, reinstalling updated player, uninstalling AIR upgrades, reinstalling AIR upgrades... no luck finding - fixing - creating a 'descriptor file' for any sort of tutorial or tutorials from the web... What the heck is the problem - i can't be the only one having this problem - i hope.

Re: [Flashcoders] bitMapData - function optimization
You could use the paletMap function or the threshold function of the
bitmapData object. Check the documentation for details.

[Flashcoders] External Interface + Google Analytics + IE7
Hi,
I have encountered a problem with an ExternalInterface.call causing
IE7 to throw a JS error.
I get an error message saying:
Line: 1
Char 14:
Error: Expected ';'
Code: 0;
URL: http://www.dijitl.co.uk/beta/
So, my guessing is that somewhere the ExternalInterface call is not
adding a semi-colon, but that IE 7 maybe getting it's knickers in a
twist. Either way, it's annoying and my tracking is not working. Can
anyone shed light on this - I am using so.addParam(allowScriptAccess,
always); with SWFObject too.
Ta
Glen
AS code is like this:
var page:String = evt.type.substr(5);
if (ExternalInterface.available) {
ExternalInterface.call (trackTesting, page);
}
Have also tried calling the pageTracker object directly -
ExternalInterface.call(pageTracker._trackPageview, page); - but no joy.
JS Code is like this:
script type=text/javascript
// ![CDATA[
var pageTracker = _gat._getTracker(UA-DELETED);
pageTracker._initData();
pageTracker._trackPageview();
function trackTesting(page) {
alert(before + page);
pageTracker._trackPageview(page);
alert(after);
}
// ]]
/script

[Flashcoders] getting SoundChannel out of a NetStream
Hi Folks, At the moment we have a project which loads in Mp3 from 2 different sources; one is progressive - We use the Sound class to Load this one the other is streaming - We use the NetStream class to load this one We have a visual effect which listens to the volume and then reacts to it, we use soundchannel for this. _soundChannel=soundObject.play() visualeffect.alpha=_soundChannel.rightPeak. This all works peachy. IF I have a Sound object. With the Netstream there doesn't seem to be any way to read any sound properties(like rightPeak in Soundchannel), since there is no way extract a soundchannel from a Netstream(which seems odd, doesn't it?) So my question; Does anyone have any clue as to how to get a Sound object or SoundChannel object from a Netstream (soundTransform is fairly useless, it will only let us change the volume parameters, not read it)... Or is this restricted with Netstream the same way we can't read pixels from a netstreamed video? thanks for any pointers! -- M.A. van't Kruis http://www.malatze.nl/ ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
RE: [Flashcoders] bitMapData - function optimization
:-) thanks... however the problem with the invert function is that it does
not preserve the transparency. Which is what I am trying to invert ( I
should have been more specific ) . So I am trying to make all transparent
pixels non-transparent. And vice-versa... will keep looking at
paletMap/threshold as it looks like a good solution.
Regards
Karim

[Flashcoders] forceSmoothing in a MovieClipLoader
I'm finding that when I use forceSmoothing in a moviecliploader, it
doesnt seem to work. It turns it OFF just fine, but never turns it
back on afterwards. Just fyi, I already tried placing the
forceSmoothing = true in the onLoadInit and onLoadComplete's, just to
see if they'd work from there, but it never seemed to get turned back
on. See code below, can someone else see what I'm doing wrong? I know
setTimeout's aren't entirely reliable...
and yes this is still AS2... (le sigh)
thx,
.m
//Portfolio loader
myPMCL.onLoadStart = function(targetMC) {
//targetMC.forceSmoothing = false;
targetMC._alpha = 0;

_root.loadermain_mc.bar_mc._xscale = 0;
};
myPMCL.onLoadProgress = function(targetMC, loadedBytes, totalBytes) {

[Flashcoders] Border color change of UILoader
Hi
Does anyone now how to change the border color of the UILoader component
when user clicks on that. I have put UILoader in the sprite container and i
need to implement that if user selects that UILoader its border color will
be changed (to red may be).
Please help me out . Here's the my dummy code for that. Basically what I
need is the border of UILoader to be shown as soon as mousedown event is
generated and the border to hide as soon as mouseup event is generated.
Any help or any new idea will be highly appreciated.
Thanks
Anuj
/CODE**
var container:Sprite=new Sprite();
var myUILoader:UILoader = new UILoader();
myUILoader.source = XYZ.swf;
myUILoader.load();
container.addChild(myUILoader);
addChild(container);
myUILoader.addEventListener(MouseEvent.MOUSE_DOWN,dragUILoader);
myUILoader.addEventListener(MouseEvent.MOUSE_UP,dropUILoader);
myUILoader.addEventListener(MouseEvent.CLICK, moveSelectedVideoOnFront);
function moveSelectedVideoOnFront(event:MouseEvent):void
{
//Brings selected UILoader on top
}
function dragUILoader(e:MouseEvent):void
{
//Allows dragging of the UILoader
}
function dropUILoader(e:MouseEvent):void
{
//Allows dropping of the UILoader
}
