I'm writing a script to Trim an Image record the current width, calculate new width and increase in the image. Here is the code below, but have issues in the layer.resize. Anyone know, whats the problem?

// 1° Determinar pasta fonte das imagens
var sourceFolder = Folder.selectDialog("Select the source folder");
// 2° Determinar pasta no qual receberá novas imagens
var destinationFolder = Folder.selectDialog("Select the destination folder");
// Get all files in the source folder
var files = sourceFolder.getFiles();
// Loop over all files
for (var i = 0; i < files.length; i++) {
// Open the file
var doc = app.open(files[i]);
// 3° Desbloquear o cadeado, transformando em camada
var layer = doc.activeLayer;
layer.blendMode = BlendMode.NORMAL;
layer.opacity = 100;
// 4° Aparar imagem
doc.trim(TrimType.TOPLEFT, true, true, true, true);
// 5° Determinando o maior lado da imagem
var longestSide = Math.max(layer.width, layer.height);
var scaleFactor = (1200 / longestSide)*100
// 6° Alterar tela de pintura 1200x1200
doc.resizeCanvas(1200, 1200, AnchorPosition.MIDDLECENTER);
// 7° CRTL+T (Transformação livre alterando a imagem para o novo tamanho calculado
layer.resize(newWidth, newHeight, AnchorPosition.MIDDLECENTER);
})();
;
// 8° Save as imagem
var saveFile = new File(destinationFolder + "/" + files[i].name);
doc.saveAs(saveFile, SaveOptions.PNG);
// 9° Fechar a imagem
doc.close(SaveOptions.DONOTSAVECHANGES);
}

    You are using variables

     

    newWidth
newHeight

     

    in

     

    layer.resize(newWidth, newHeight, AnchorPosition.MIDDLECENTER);

     

    but I don't see their definition in the code 🤷‍

      Follow the right code even is not working

       

      // 1° Determinar pasta fonte das imagens
      var sourceFolder = Folder.selectDialog("Select the source folder");
      // 2° Determinar pasta no qual receberá novas imagens
      var destinationFolder = Folder.selectDialog("Select the destination folder");
      // Get all files in the source folder
      var files = sourceFolder.getFiles();
      // Loop over all files
      for (var i = 0; i < files.length; i++) {
      // Open the file
      var doc = app.open(files[i]);
      // 3° Desbloquear o cadeado, transformando em camada
      var layer = doc.activeLayer;
      layer.blendMode = BlendMode.NORMAL;
      layer.opacity = 100;
      // 4° Aparar imagem
      doc.trim(TrimType.TOPLEFT, true, true, true, true);
      // 5° Determinando o maior lado da imagem
      var longestSide = Math.max(layer.width, layer.height);
      var scaleFactor = (1200 / longestSide)*100
      // 6° Alterar tela de pintura 1200x1200
      doc.resizeCanvas(1200, 1200, AnchorPosition.MIDDLECENTER);
      // 7° CRTL+T (Transformação livre alterando a imagem para o novo tamanho calculado
      layer.resize(scaleFactor, scaleFactor, AnchorPosition.MIDDLECENTER);
      })();
      ;
      // 8° Save as imagem
      var saveFile = new File(destinationFolder + "/" + files[i].name);
      doc.saveAs(saveFile, SaveOptions.PNG);
      // 9° Fechar a imagem
      doc.close(SaveOptions.DONOTSAVECHANGES);
      }

      An ArtLayer object does not have a "width" or "height" property. But there is a property "bounds". Read the documentation carefully and do not use fictitious properties and methods.

        It's always good to use .value and to explicitly set pixels as the unit of measure when resizing. I'll update this post later to better explain what I mean.

         

        EDIT:

         

        var origRulerUnits = app.preferences.rulerUnits;
app.preferences.rulerUnits = Units.PIXELS;
// YOUR CODE
app.preferences.rulerUnits = origRulerUnits;

         

        Also, consider the following when performing math:

         

        alert(activeDocument.width);
alert(activeDocument.width.value);
alert(activeDocument.activeLayer.width);

         

        You need to remove "px" using .value and unlike canvas, there is no width or height of a layer, unless you do something like:

         

        var origRulerUnits = app.preferences.rulerUnits;
app.preferences.rulerUnits = Units.PIXELS;

var layerBounds = activeDocument.activeLayer.bounds;
var layerLeft = layerBounds[0].value;
var layerTop = layerBounds[1].value;
var layerRight = layerBounds[2].value;
var layerBottom = layerBounds[3].value;
var layerWidth = layerBounds[2].value - layerBounds[0].value;
var layerHeight = layerBounds[3].value - layerBounds[1].value;
var layerXCenter = layerLeft + layerWidth / 2;
var layerYCenter = layerTop + layerHeight / 2;

app.preferences.rulerUnits = origRulerUnits;

         

         

        //    Bounds:
//    + - - - - - - - [1] - - - - - - - +
//    |                                 |
//    |                                 |
//   [0]                               [2]
//    |                                 |
//    |                                 |
//    + - - - - - - - [3] - - - - - - - +

         

        Also take a look at the following:
