Horizontally Center Layer

[jonr29200860]

I need to horizontally center this text layer in JavaScript

Doing this manually requires clicking this button:

The end result being:

Is there a way to do this in JavaScript?

I got this code with JavaScript listener, it is working. You need to select layers before running this script, one of them have to be locked - "background" layer.

var idAlgn = charIDToTypeID( "Algn" );

    var desc32 = new ActionDescriptor();

    var idnull = charIDToTypeID( "null" );

        var ref5 = new ActionReference();

        var idLyr = charIDToTypeID( "Lyr " );

        var idOrdn = charIDToTypeID( "Ordn" );

        var idTrgt = charIDToTypeID( "Trgt" );

        ref5.putEnumerated( idLyr, idOrdn, idTrgt );

    desc32.putReference( idnull, ref5 );

    var idUsng = charIDToTypeID( "Usng" );

    var idADSt = charIDToTypeID( "ADSt" );

    var idAdCH = charIDToTypeID( "AdCH" );

    desc32.putEnumerated( idUsng, idADSt, idAdCH );

executeAction( idAlgn, desc32, DialogModes.NO );

bound = (aD = activeDocument).activeLayer.bounds, h = aD.width / 2
aD.activeLayer.translate(h - (bound[0] + ((bound[2] - bound[0]) / 2)))

Set a selection you want to align the layer to.  The selection for be the canvas size, a single pixel any area you want to align the layer to. Like an Imager location in a collage template.  Then you use two Photoshop Align layers to selection to align the layers vertically and horizontally to the selection there are 9 relative alignments possible.

Here is how I stamp and Image name onto to an image area aligned to one of the 9 posible alignments. Left top, center top, Top right etc.

var Position = Number(Collage.msgPnl.grp5a.dd1.selection.index) + 1;

switch (Position){

case 1 : align('AdLf'); align('AdTp'); break;

case 2 : align('AdCH'); align('AdTp'); break;

case 3 : align('AdRg'); align('AdTp'); break;

case 4 : align('AdLf'); align('AdCV'); break;

case 5 : align('AdCH'); align('AdCV'); break;

case 6 : align('AdRg'); align('AdCV'); break;

case 7 : align('AdLf'); align('AdBt'); break;

case 8 : align('AdCH'); align('AdBt'); break;

case 9 : align('AdRg'); align('AdBt'); break;

default : break;

function align(method) {

   var desc = new ActionDescriptor();

   var ref = new ActionReference();

   ref.putEnumerated( charIDToTypeID( "Lyr " ), charIDToTypeID( "Ordn" ), charIDToTypeID( "Trgt" ) );

   desc.putReference( charIDToTypeID( "null" ), ref );

   desc.putEnumerated( charIDToTypeID( "Usng" ), charIDToTypeID( "ADSt" ), charIDToTypeID( method ) );

   try{

       executeAction( charIDToTypeID( "Algn" ), desc, DialogModes.NO );

       }

   catch(e){}

}
