Accessing via AS3 (for export) the gradient of a rectangle created in the Flash Editor

Question
I need to export the gradient settings of a rectangle created with the Flash editor. Our artist creates a rectangle with the gradient in a .fla. Is it possible to retrieve the gradient parameters from the .swf or from a flash plugin I could write?
Solution
I needed this a couple of years ago, luckily Tink already wrote an extension/JSFL script: Copy Fill as AS3.
I remember having small problems with gradients depending on the selection, but forgot what was that all about. If the extension doesn't work properly, here's my slightly changed version:
document = fl.getDocumentDOM();
selection = document.getSelectionRect();
selection.left != undefined ? useSelection = true : useSelection = false;
useSelection ? fill = document.getCustomFill( "selection" ) : fill = document.getCustomFill( "toolbar" );
fl.outputPanel.clear();
var output = "";
if(fill.style != "noFill"){
if( fill.style == "solid" )
{
if( fill.color.length == 9 )
{
a = Math.round( ( parseInt( "0x" + fill.color.substr( 7, 2 ) ) / 255 ) * 100 ) / 100;
output += "beginFill( 0x" + fill.color.substr( 1, 6 ).toUpperCase() + ", " + a + " );";
}
else
{
output += "beginFill( 0x" + fill.color.substr( 1, 6 ).toUpperCase() + ", 1 );";
}
}
else if( fill.style == "linearGradient" )
{
output += "beginGradientFill( GradientType.LINEAR, ";
}
else if( fill.style == "radialGradient" )
{
output += "beginGradientFill( GradientType.RADIAL, ";
}
if( fill.style != "solid" )
{
c = new Array();
a = new Array()
for( i = 0; i < fill.colorArray.length; i++ )
{
if(fill.colorArray){
if( fill.colorArray[ i ].length == 9 )
{
c.push( "0x" + fill.colorArray[ i ].substr( 1, 6 ).toUpperCase() );
a.push( Math.round( ( parseInt( "0x" + fill.colorArray[ i ].substr( 7, 2 ) ) / 255 ) * 100 ) / 100 );
}
else
{
c.push( "0x" + fill.colorArray[ i ].substr( 1, 6 ).toUpperCase() );
a.push( 1 );
}
}
}
document.setSelectionRect({left:0,top:0,right:0,bottom:0},true);
document.setSelectionRect(selection,true);
localX = fill.matrix.tx - selection.left;
localY = fill.matrix.ty - selection.top
if(localX < 0 || localY < 0) error = true;
else error = false;
if(useSelection)
{
matrix = 'new Matrix(' + fill.matrix.a + ', ' + fill.matrix.b + ', ' + fill.matrix.c + ', ' + fill.matrix.d + ', ' + localX + ', ' + localY + ')';
}
else
{
matrix = 'new Matrix(' + fill.matrix.a + ', ' + fill.matrix.b + ', ' + fill.matrix.c + ', ' + fill.matrix.d + ', ' + fill.matrix.tx + ', ' + fill.matrix.ty + ')';
}
switch(fill.overflow){
case "Extend":
spreadMethod = "SpreadMethod.PAD";
break;
case "Repeat":
spreadMethod = "SpreadMethod.REPEAT";
break;
case "Reflect":
spreadMethod = "SpreadMethod.REFLECT";
break;
}
!fill.linearRGB ? interpolationMethod = 'InterpolationMethod.RGB' : interpolationMethod = 'InterpolationMethod.LINEAR_RGB';
if(fill.focalPoint != 0) output += "[ " + c.join( ", " ) + " ], [ " + a.join( ", " ) + " ], [ " + fill.posArray.join( ", " ) + " ], " + matrix + ", " + spreadMethod + ", " + interpolationMethod + ", " + fill.focalPoint + "); ";
else output += "[ " + c.join( ", " ) + " ], [ " + a.join( ", " ) + " ], [ " + fill.posArray.join( ", " ) + " ], " + matrix + ", " + spreadMethod + ", " + interpolationMethod + "); ";
}
if(error)
{
fl.trace("You have moved your selection!Please re-select the shape and run this command again");
}else
{
fl.clipCopyString( output );
fl.trace( output );
}
}else{
fl.trace( 'No Fill is Selected' );
}
If you save this as Copy Fill as AS3.jsfl in Flash's Commands folder, it should pop up in the Commands menu in the IDE.

OTHER TIPS
Take a look at the excelent library as3swf written by Claus Wahlers, from wich you can
parse, create, modify and publish SWF files
.
Sothink Decompiler lets you decompile the swf so you get the original FLA. http://www.sothink.com/product/flashdecompiler/ it is paid but they have a free trial.
Couldn't remember if you could export to fla in the trial.
