Dear ALL,

I have a document with multiple Page size eg its mixture of A3, A4 & letter size. Is there is any way that PDF can list the available page sizes & count of the no. eg

  • A4-4pages,
  • A3-12 pages,
  • A1-9pages,
  • letter -2 pages etc.

I would like to check before printing the document as it get stuck in printer due to non availabity of the right paper, eg A1, letter etc.. Please advice. Any Jawascript may work..?

It's pretty simple to loop through the page sizes using JavaScript; here's a chunk of example code you can run from the console. Add more pages sizes as required, remember Acrobat measures everything in Points (72 pt per inch):

console.println("There are " + this.numPages + " pages in this document");
// counters
var numA3 = 0;
var numA4 = 0;
var numUSL = 0; // etc.
// helper function to compare a number with some wiggle room - we look for portrait and landscape possibilities
function inRange(wid,hei,targetWid,targetHei) {
    var wiggle = 2; // amount of error to allow in Points. Not all PDF software creates perfectly-sized pages
    return (wid>=(targetWid-wiggle) && wid<=(targetWid+wiggle)) &&  (hei>=(targetHei-wiggle) && hei<=(targetHei+wiggle)) || (hei>=(targetWid-wiggle) && hei<=(targetWid+wiggle)) &&  (wid>=(targetHei-wiggle) && wid<=(targetHei+wiggle))
}
for (pagenum=0;pagenum<this.numPages;pagenum++) {
    var pbox = this.getPageBox("Crop",pagenum);
    var width = (pbox[2] - pbox[0]);
    var height = (pbox[1] - pbox[3]);
    var recognized = false;
    if (inRange(width,height,841,1188)) { numA3++; recognized = true; }
    if (inRange(width,height,595,841)) { numA4++; recognized = true; }
    if (inRange(width,height,594,792)) { numUSL++; recognized = true; }
    // etc...
    if (!recognized) console.println("Page " + (pagenum+1) + " has a width of " + (width/72) + " and a height of " + (height/72) + "inches");
}
console.println(numA3 + " A3 pages");
console.println(numA4 + " A4 pages");
console.println(numUSL + " US Letter pages");
console.println((this.numPages++ - (numA3+numA4+numUSL)) + " other pages");

This can be done using a custom-made script. If you're interested in purchasing such a tool feel free to contact me privately at try6767 at gmail.com.

Dear Test Screen Name, got it, thanks!

Will try the same, secondly, is there a way to fix the decimal values in the line

console.println("Page " + (pagenum+1) + " has a width of " + (width/72) + " and a height of " + (height/72) + "inches"); 

sometime its printing till 15 decimal places.

eg one the output is

Page 7 has a width of 16.541666666666668 and a height of 11.694444444444445inches

is there a way that it can rounup to 2 decimal places. Thanks


To round a number in JS, use the .toFixed() method. Here's a revised script that also outputs to an alert box:

var msgText = "There are " + this.numPages + " pages in this document\n";
// counters
var numA3 = 0;
var numA4 = 0;
var numUSL = 0;
// helper function to compare a number with some wiggle room
function inRange(wid,hei,targetWid,targetHei) {
    var wiggle = 2; // amount of error to allow
    return (wid>=(targetWid-wiggle) && wid<=(targetWid+wiggle)) &&  (hei>=(targetHei-wiggle) && hei<=(targetHei+wiggle)) || (hei>=(targetWid-wiggle) && hei<=(targetWid+wiggle)) &&  (wid>=(targetHei-wiggle) && wid<=(targetHei+wiggle))
}
for (pagenum=0;pagenum<this.numPages;pagenum++) {
    var pbox = this.getPageBox("Crop",pagenum);
    var width = (pbox[2] - pbox[0]);
    var height = (pbox[1] - pbox[3]);
    var recognized = false;
    if (inRange(width,height,841,1188)) { numA3++; recognized = true; }
    if (inRange(width,height,595,841)) { numA4++; recognized = true; }
    if (inRange(width,height,594,792)) { numUSL++; recognized = true; }
    if (!recognized) msgText += ("Page " + (pagenum+1) + " has a width of " + (width/72).toFixed(2) + " and a height of " + (height/72).toFixed(2) + "inches\n");
}
msgText += numA3 + " A3 pages\n" + numA4 + " A4 pages\n" + numUSL + " US Letter pages\n" + (this.numPages++ - (numA3+numA4+numUSL)) + " other pages";
app.alert(msgText);
