    Does .duplicate() copy element to a new document?

    i73 Level 1

      I am looking at the 'Export Layers To Files.jsx' to convert the parts of the exportChildren to C++ for my plugin, I need to know does .duplicate() duplicate a Element to a new document (does it copy the element, create a new doc, and paste it)?

       

      function exportChildren(dupObj, orgObj, exportInfo, dupDocRef, fileNamePrefix) {

          for( var i = 0; i < dupObj.artLayers.length; i++) {

              if (exportInfo.visibleOnly) { // visible layer only

                  if (!orgObj.artLayers[i].visible) {

        continue;

        }

              }

              dupObj.artLayers[i].visible = true;

       

       

              var layerName = dupObj.artLayers[i].name;  // store layer name before change doc

              var duppedDocumentTmp = dupDocRef.duplicate();

              if ((psdIndex == exportInfo.fileType)||(png24Index == exportInfo.fileType)||(png8Index == exportInfo.fileType)) { // PSD: Keep transparency

                  removeAllInvisible(duppedDocumentTmp);

          Perhaps! In that script it would depend on what "dupDocRef" is.   There are many duplicate methods in  Adobe Photoshop's Scripting DOM.

           

          Method    Paramaters                             Parameter type                     Returns           What it does
          duplicate([relativeObject][, insertionLocation]) ArtLayer|LayerSet,ElementPlacement ArtLayer|LayerSet Creates a duplicate of the object .
          duplicate([targetDocument])                      Document                           Channel           Duplicates the channel.
          duplicate([name ][, mergeLayersOnly])            string,boolean                     Document          Creates a duplicate of the document object.
          duplicate([relativeObject][, insertionLocation]) ArtLayer|LayerSet,ElementPlacement LayerSet          Creates a duplicate of the object.
          duplicate(name)                                  string                                               Duplicates pathItem object with the new name.
          

           

          Look like it is method 4 the way it is coded so yes it creates a new document in Photoshop and returns the document object in the variable  duppedDocumentTmp

          It look line method 4 because of the variable name used by the coder implies a document object is expected to be returned.

           

          Then all the invisible layer in the duplicated document are then removed by the script in this new document.
