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

I need to export the gradient settings of a rectangle created with the Flash editor. Ou开发者_运维技巧r 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?

Take a look at the excelent library as3swf written by Claus Wahlers, from wich you can

parse, create, modify and publish SWF files

.

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.

HTH

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.
