Hi all,

I want to distort (free transform) the four corners of a layer (rectangle shape) to 4 specific coordinates.
For example: [[971,776],[1518,688],[1519,974],[968,1312]]

Scriptlistener showed this, but I dont see any coordinates:

var idTrnf = charIDToTypeID( "Trnf" );
    var desc252 = new ActionDescriptor();
    var idFTcs = charIDToTypeID( "FTcs" );

    var idQcsa = charIDToTypeID( "Qcsa" );
    desc252.putEnumerated( idFTcs, idQCSt, idQcsa );
    var idOfst = charIDToTypeID( "Ofst" );

@r-bin posted a function a while ago; p1 is an array of the current bounds, p2 an darray of the four target-points. 

////// free transform by r-bin //////
function non_affine_transform(p0, p1) 
{  
try {
var d = new ActionDescriptor();
var r = new ActionReference();
r.putEnumerated(stringIDToTypeID("layer"), stringIDToTypeID("ordinal"), stringIDToTypeID("targetEnum"));
d.putReference(stringIDToTypeID("null"), r);

var l = new ActionList();
l.putUnitDouble(stringIDToTypeID("pixelsUnit"), p0[0]);
l.putUnitDouble(stringIDToTypeID("pixelsUnit"), p0[1]);
l.putUnitDouble(stringIDToTypeID("pixelsUnit"), p0[2]);
l.putUnitDouble(stringIDToTypeID("pixelsUnit"), p0[3]);
d.putList(stringIDToTypeID("rectangle"), l );

var l = new ActionList();
l.putUnitDouble(stringIDToTypeID("pixelsUnit"), p1[0][0]);
l.putUnitDouble(stringIDToTypeID("pixelsUnit"), p1[0][1]);
l.putUnitDouble(stringIDToTypeID("pixelsUnit"), p1[1][0]);
l.putUnitDouble(stringIDToTypeID("pixelsUnit"), p1[1][1]);
l.putUnitDouble(stringIDToTypeID("pixelsUnit"), p1[2][0]);
l.putUnitDouble(stringIDToTypeID("pixelsUnit"), p1[2][1]);
l.putUnitDouble(stringIDToTypeID("pixelsUnit"), p1[3][0]);
l.putUnitDouble(stringIDToTypeID("pixelsUnit"), p1[3][1]);
d.putList(stringIDToTypeID("quadrilateral"), l);

d.putEnumerated(stringIDToTypeID("interpolation"), stringIDToTypeID("interpolationType"), stringIDToTypeID("bicubic"));

executeAction(stringIDToTypeID("transform"), d, DialogModes.NO); 

return true;
}
catch (e) { alert(e); return false; }        
};

    Hi, thanks for the solution.
    Is it possible to get Distort points?
    I mean transformation cordinats

      Looking at the recorded code, more is going on under the hood than one appreciates when simply moving the four points via Transform > Distort in the GUI.

       

      Here I have converted your raw recording via the Clean SL script, which makes things just a little more legible:

       

      var c2t = function (s) {
	return app.charIDToTypeID(s);
};

var s2t = function (s) {
	return app.stringIDToTypeID(s);
};

var descriptor = new ActionDescriptor();
var descriptor2 = new ActionDescriptor();
var descriptor3 = new ActionDescriptor();
var descriptor4 = new ActionDescriptor();
var descriptor5 = new ActionDescriptor();
var reference = new ActionReference();
var reference2 = new ActionReference();

descriptor.putEnumerated( s2t( "freeTransformCenterState" ), s2t( "quadCenterState" ), s2t( "QCSAverage" ));
descriptor2.putUnitDouble( s2t( "horizontal" ), s2t( "pixelsUnit" ), 700.958190 );
descriptor2.putUnitDouble( s2t( "vertical" ), s2t( "pixelsUnit" ), 367.508658 );
descriptor.putObject( s2t( "offset" ), s2t( "offset" ), descriptor2 );
descriptor.putUnitDouble( s2t( "width" ), s2t( "percentUnit" ), 148.730064 );
descriptor.putUnitDouble( s2t( "height" ), s2t( "percentUnit" ), 92.668201 );
descriptor3.putUnitDouble( s2t( "horizontal" ), s2t( "angleUnit" ), -3.365472 );
descriptor3.putUnitDouble( s2t( "vertical" ), s2t( "angleUnit" ), 0.000000 );
descriptor.putObject( s2t( "skew" ), c2t( "Pnt " ), descriptor3 );
descriptor.putUnitDouble( s2t( "angle" ), s2t( "angleUnit" ), 0.490732 );
descriptor4.putUnitDouble( s2t( "horizontal" ), s2t( "percentUnit" ), 0.086137 );
descriptor4.putUnitDouble( s2t( "vertical" ), s2t( "percentUnit" ), -0.010603 );
descriptor.putObject( s2t( "using" ), c2t( "Pnt " ), descriptor4 );
reference.putIdentifier( s2t( "layer" ), 26 );
descriptor5.putReference( s2t( "from" ), reference );
reference2.putIdentifier( s2t( "layer" ), 26 );
descriptor5.putReference( s2t( "to" ), reference2 );
descriptor.putObject( s2t( "replaceLayer" ), s2t( "transform" ), descriptor5 );
executeAction( s2t( "transform" ), descriptor, DialogModes.NO );
