Open an AI file with jsx script at a specific height

I am trying to write a script that will open an Adobe Illustrator file at a specific height. But I am having trouble finding out why this code isn't working.

function openPdfPage (filePath) {

    try {
  
      var pdfOpenOpts = new PDFOpenOptions;
      pdfOpenOpts.antiAlias = true;
      pdfOpenOpts.bitsPerChannel = BitsPerChannelType.SIXTEEN;
      pdfOpenOpts.cropPage = CropToType.BOUNDINGBOX;
      pdfOpenOpts.mode = OpenDocumentMode.RGB;
      pdfOpenOpts.resolution = 300;
      pdfOpenOpts.constrainProportions = true;
      pdfOpenOpts.height = new UnitValue(50, 'px');
      pdfOpenOpts.suppressWarnings = false;
      pdfOpenOpts.usePageNumber = true;
      pdfOpenOpts.page = 1;
  
      app.open(new File(filePath), pdfOpenOpts);
  
      return app.activeDocument
  
    } catch (e) {
        alert(e.message);

        return undefined};
  
  }

    Correct answer c.pfaffenbichler

    Unfortunately I have no way of knowing what the width would be, so I set the constrainProportions to true. I did think setting the width might be necessary so I set it for a test on one I know the width and it still didn't work for me.


    The width works for me. 

    aaa("~/Desktop/Untitled-2.ai");
function aaa (filePath) {
var idopen = stringIDToTypeID( "open" );
var desc10 = new ActionDescriptor();
var idas = stringIDToTypeID( "as" );
var desc11 = new ActionDescriptor();
/*var idname = stringIDToTypeID( "name" );
desc11.putString( idname, """Untitled-1.ai""" );*/
var idcrop = stringIDToTypeID( "crop" );
var idcropTo = stringIDToTypeID( "cropTo" );
var idtrimBox = stringIDToTypeID( "trimBox" );
desc11.putEnumerated( idcrop, idcropTo, idtrimBox );
var idresolution = stringIDToTypeID( "resolution" );
var iddensityUnit = stringIDToTypeID( "densityUnit" );
desc11.putUnitDouble( idresolution, iddensityUnit, 300.000000 );
var idmode = stringIDToTypeID( "mode" );
var idcolorSpace = stringIDToTypeID( "colorSpace" );
var iduseICCProfile = stringIDToTypeID( "useICCProfile" );
desc11.putEnumerated( idmode, idcolorSpace, iduseICCProfile );
var iddepth = stringIDToTypeID( "depth" );
desc11.putInteger( iddepth, 8 );
var idantiAlias = stringIDToTypeID( "antiAlias" );
desc11.putBoolean( idantiAlias, true );
var idwidth = stringIDToTypeID( "width" );
var idpixelsUnit = stringIDToTypeID( "pixelsUnit" );
desc11.putUnitDouble( idwidth, idpixelsUnit, 71.000000 );
var idheight = stringIDToTypeID( "height" );
var idpixelsUnit = stringIDToTypeID( "pixelsUnit" );
desc11.putUnitDouble( idheight, idpixelsUnit, 50.000000 );
var idconstrainProportions = stringIDToTypeID( "constrainProportions" );
desc11.putBoolean( idconstrainProportions, true );
var idsuppressWarnings = stringIDToTypeID( "suppressWarnings" );
desc11.putBoolean( idsuppressWarnings, false );
var idreverse = stringIDToTypeID( "reverse" );
desc11.putBoolean( idreverse, true );
var idselection = stringIDToTypeID( "selection" );
var idpdfSelection = stringIDToTypeID( "pdfSelection" );
var idpage = stringIDToTypeID( "page" );
desc11.putEnumerated( idselection, idpdfSelection, idpage );
var idpageNumber = stringIDToTypeID( "pageNumber" );
desc11.putInteger( idpageNumber, 1 );
var idPDFGenericFormat = stringIDToTypeID( "PDFGenericFormat" );
desc10.putObject( idas, idPDFGenericFormat, desc11 );
var idnull = stringIDToTypeID( "null" );
desc10.putPath( idnull, new File( filePath ) );
executeAction( idopen, desc10, DialogModes.NO );
};

    HAve you tried recording AM-code for the operation with ScriptingListener.plugin?

      Yes, I did try that, it didn't work either. 

        function openPDFHard(filePath) {

    var idOpn = charIDToTypeID( "Opn " );
    var desc228 = new ActionDescriptor();
    var idAs = charIDToTypeID( "As  " );
        var desc229 = new ActionDescriptor();
        var idCrop = charIDToTypeID( "Crop" );
        var idcropTo = stringIDToTypeID( "cropTo" );
        var idboundingBox = stringIDToTypeID( "boundingBox" );
        desc229.putEnumerated( idCrop, idcropTo, idboundingBox );
        var idRslt = charIDToTypeID( "Rslt" );
        var idRsl = charIDToTypeID( "#Rsl" );
        desc229.putUnitDouble( idRslt, idRsl, 300.000000 );
        var idMd = charIDToTypeID( "Md  " );
        var idClrS = charIDToTypeID( "ClrS" );
        var idRGBC = charIDToTypeID( "RGBC" );
        desc229.putEnumerated( idMd, idClrS, idRGBC );
        var idDpth = charIDToTypeID( "Dpth" );
        desc229.putInteger( idDpth, 16 );
        var idAntA = charIDToTypeID( "AntA" );
        desc229.putBoolean( idAntA, true );
        var idHght = charIDToTypeID( "Hght" );
        var idPxl = charIDToTypeID( "#Pxl" );
        desc229.putUnitDouble( idHght, idPxl, 50.000000 );
        var idCnsP = charIDToTypeID( "CnsP" );
        desc229.putBoolean( idCnsP, true );
        var idsuppressWarnings = stringIDToTypeID( "suppressWarnings" );
        desc229.putBoolean( idsuppressWarnings, false );
        var idRvrs = charIDToTypeID( "Rvrs" );
        desc229.putBoolean( idRvrs, true );
        var idfsel = charIDToTypeID( "fsel" );
        var idpdfSelection = stringIDToTypeID( "pdfSelection" );
        var idpage = stringIDToTypeID( "page" );
        desc229.putEnumerated( idfsel, idpdfSelection, idpage );
        var idPgNm = charIDToTypeID( "PgNm" );
        desc229.putInteger( idPgNm, 1 );
    var idPDFG = charIDToTypeID( "PDFG" );
    desc228.putObject( idAs, idPDFG, desc229 );
    var idnull = charIDToTypeID( "null" );
    desc228.putPath( idnull, new File(filePath) );
    var idDocI = charIDToTypeID( "DocI" );
    desc228.putInteger( idDocI, 60 );
executeAction( idOpn, desc228, DialogModes.NO );
  }

      What is »didn’t work« supposed to describe exactly?

        What exactly do you mean by "doesn't work"? 

         

        When I call the function, the file is opened:

         

        openPdfPage ("~/Desktop/test.ai");

          Thanks for the response.
          Correct, the file opens but the image doesn't have the specified height.

          So what height is the bounds of the source object and what height do you wish to rasterize to?
