Create a document with the same number of pages as the selected pdf

[arekh2792424]

Hello everyone,

     I am running into a problem where my indesign just completely freezes returning no error code when I run this script, the goal is that indesign will create a document with the same number of pages as the selected pdf. This is what I have so far:

Initialization();

function Initialization() {

    //prompt user to select a file.

    var selectedFile = File.openDialog("Choose a PDF File");

    //Retrieve the page count of the selected file.

    var pageCount = readPageCount(selectedFile);

    createDoc(selectedFile, pageCount);

}

// This function is based on another script and believe the issue lies within this section here:

function readPageCount(selectedFile) {

  // Read in first line of section

  var theLine = selectedFile.readln();

  // Locate the line containing the /Count entry

  while(theLine.indexOf("/Count") == -1)

  {

  theLine = selectedFile.readln();

  }

  // Extract the page count

  return parseInt(theLine.substring(theLine.indexOf("/Count") +6), 10);

}

function createDoc(selectedFile, pageCount) {

    //Create a new document with the same number of pages as the selected document.

    var BC10UP = app.documents.add();

    with (BC10UP.documentPreferences) {

        pageHeight = "11in";

        pageWidth = "8.5in";

        pageOrientation = PageOrientation.landscape;

        pagesPerDocument = pageCount; }

}

any help or advice is much appreciated!!

Hi,

1. selectedFile should be opened before calling readln()

2. looks like not every pdf contain the string "/Count" (at least some on my side)

do a "while loop" with selectedFile.eof condition and break a loop if the string "/Count" is found

something like:

//...
selectedFile.open("r");
do {
    theLine = selectedFile.readln();
    theIndex = theLine.indexOf("/Count");
    if (theIndex >=0) {
          selectedFile.close();
          return parseInt(theLine.substring(theIndex + 6), 10)
          }
     }
    while (!selectedFile.eof)
selectedFile.close();
return -1
//....

if -1 returned desired string is not found
