    create new fill layer behind image

    bradleya17648820

      I am currently selecting an image and resizing the canvas around it which works fine, however, I need to create a white fill layer and be placed at the end so I can use transparent images. I currently have some js which create a new fill layer but it sits on top and just gives me a blank white png file. If someone could show me how to place this below the image layer it would be create

       

        var NoImages = File.openDialog("Select your logo file", false);
      
      
          if (NoImages !== null) { 
              var doc = open(NoImages, OpenDocumentType.PNG.JPEG); // Open PNG file
              
              if (doc == null) {
                throw "Something is wrong with the file.";
              }
      
      
              var startState = doc.activeHistoryState;       // save for undo
              var initialPrefs = app.preferences.rulerUnits; // will restore at end
              app.preferences.rulerUnits = Units.PIXELS;     // use pixels
          
              // Folder selection dialog
              var destFolder = Folder.selectDialog( "Choose an output folder");
      
      
              if (destFolder == null) {
                // User canceled, just exit
                throw "";
              }
      
      
              // Save icons in PNG using Save for Web.

              sfw.PNG8 = false; // use PNG-24

          I'm trying to understand what you are trying to do.  It looks like you are coding resize canvas like your are doing a resize image.  the statement is all wrong its just width height and anchor point. If you were to resize your logo not the canvas but the image it would get more and more distorted by these unconstrained image resize.  Why would you want to put your logo  the same size on nine different size white canvases which I think is what you are trying to do. Where would you like your logo to be  on each canvas?   Normally you place your logo on image. sized for the image's size and resolution.   That is very easy to do. I have posted as script to do the several times.

           

          Here it is again with a slight change you can position you logo in the lower left or right corner now.

          #target photoshop;  
          app.bringToFront();  
          var logoFile = "~/Desktop/JJMack.png"; // Watermark file should be large for resize down works better than up
          var LogoSize = 10; // percent of document height to resize Watermark to
          var LogoMargin = 1;                                         // percent of Document height the Watermark should have as a margin
          var BottomLetf = false; // false = Bottom Right true Bottom Left 
          
          
          placeWatermark(logoFile, LogoSize, LogoMargin);             // Place Watermark  into the bottom right of document
          
          
          function placeWatermark(Image,Size,Margin){  
          if(!documents.length) return;   // if no document return
          try{  
          var doc = app.activeDocument; // set Doc object to active document
          app.displayDialogs = DialogModes.NO; // Dialog off 
          var strtRulerUnits = app.preferences.rulerUnits; // Save Users ruler units 
          var strtTypeUnits = app.preferences.typeUnits; // Save Users Type units 
          app.preferences.rulerUnits = Units.PIXELS; // work with pixels 
          app.preferences.typeUnits = TypeUnits.PIXELS; // work with pixels 
          var fileObj = new File(Image);                 // the passed file
          if(!fileObj.exists){   // If file does not exits tell user 
          alert(fileObj.name  + " does not exist!");  
          return;  
          }  
          placeFile(fileObj); // Place in file the Watermark png file
          activeDocument.activeLayer.resize(100 ,100,AnchorPosition.MIDDLECENTER); // Insure Place did not scale layer  
          var SB = activeDocument.activeLayer.bounds; // get layers bounds 
          var layerHeight = SB[3] - SB[1]; // get layers height  
          var resizePercent = (100/layerHeight)*(Size/100*doc.height.value); // Percent to resize by 
          activeDocument.activeLayer.resize(resizePercent ,resizePercent,AnchorPosition.MIDDLECENTER);  // Resize width and height by percentage 
          SB = activeDocument.activeLayer.bounds; // get resized layers bounds  
          activeDocument.activeLayer.translate(-SB[0].value,-SB[1].value); // Move resized layer to top left canvas corner 
          var LayerWidth = (SB[2].value - SB[0].value);  
          var LayerHeight = (SB[3].value - SB[1].value);  
          marginSize = Margin/100*doc.height.value; // Margin size
          // move resized watermark into the document lower right corner with some margin or lower left
          if  ( BottomLetf) {activeDocument.activeLayer.translate(marginSize,( doc.height.value -marginSize - LayerHeight));}
          else {activeDocument.activeLayer.translate((doc.width.value -marginSize - LayerWidth),( doc.height.value -marginSize - LayerHeight));}
          }
          catch(e) { alert(e + ': on line ' + e.line); } // inform user of error  
          finally{  
          app.preferences.rulerUnits = strtRulerUnits; // Restore user ruler units  
          app.preferences.typeUnits = strtTypeUnits; // Restore user type units    
          };  
          }; 
          
          function placeFile(placeFile) {  
              var desc21 = new ActionDescriptor();  
              desc21.putPath( charIDToTypeID('null'), new File(placeFile) );

            Try adding this to your script:

             

            createFill ();
            var fillLayer = doc.activeLayer;
            fillLayer.move(doc.layers[doc.layers.length-1], ElementPlacement.PLACEAFTER)
            
            
            function createFill(){
                var idMk = charIDToTypeID( "Mk  " );
                    var desc4 = new ActionDescriptor();
                    var idnull = charIDToTypeID( "null" );
                        var ref1 = new ActionReference();
                        var idcontentLayer = stringIDToTypeID( "contentLayer" );
                        ref1.putClass( idcontentLayer );
                    desc4.putReference( idnull, ref1 );
                    var idUsng = charIDToTypeID( "Usng" );
                        var desc5 = new ActionDescriptor();
                        var idType = charIDToTypeID( "Type" );
                            var desc6 = new ActionDescriptor();
                            var idClr = charIDToTypeID( "Clr " );
                                var desc7 = new ActionDescriptor();
                                var idRd = charIDToTypeID( "Rd  " );
                                desc7.putDouble( idRd, 255.000000 );
                                var idGrn = charIDToTypeID( "Grn " );
                                desc7.putDouble( idGrn, 255.000000 );
                                var idBl = charIDToTypeID( "Bl  " );
                                desc7.putDouble( idBl, 255.000000 );

                            desc6.putObject( idClr, idRGBC, desc7 );
                        var idsolidColorLayer = stringIDToTypeID( "solidColorLayer" );
                        desc5.putObject( idType, idsolidColorLayer, desc6 );
                    var idcontentLayer = stringIDToTypeID( "contentLayer" );
                    desc4.putObject( idUsng, idcontentLayer, desc5 );
                executeAction( idMk, desc4, DialogModes.NO );
            
            }
