Detect landscape format

Detect landscape format

Hej volks,

i'm using pdffonts/pdfinfo on my linux box to determine different
properties of a pdf file. The last thing i'm missing is a check for
landscape format. Pdfinfo gives the same page sizes for a normal and a
landscape pdf:

normal.pdf:
Page size:      595.22 x 842 pts (A4)

landscape.pdf:
Page size:      595 x 842 pts (A4)

Anyone a clue how to determine if the file is in landscape format?

Thanks alot,
mowsen

$ pdfinfo mydoc.pdf | grep 'Page size'
Page size:      612 x 792 pts (letter)

$ pdfinfo mydoc.pdf | grep 'Page size' |\
   awk '{if($3<$5)print "portrait"; else print "landscape"}'
portrait

the wired thing is that pdfinfo gives me wrong dimensions on my sample
landscape.pdf. i assume it gives wrong page sizes when the pdf is
actually not landscape but was rotated 180=B0! my solution is a small
java app with iText as follows which gives the right dimensions:


import java.io.FileOutputStream;


import com.lowagie.text.*;
import com.lowagie.text.pdf.*;


public class CheckSize {

    public static void main(String[] args) {
	try {
	    String readfrom =3D args[0];
	    PdfReader reader =3D new PdfReader(readfrom);
	    System.out.println(reader.getPageSizeWithRotation(1));
	}
	catch (Exception de) {
            de.printStackTrace();
        }
    }
}

90=B0 of course.

Well, dimensions you want :-)

It's the nice distinction between the document dimensions,
and the "viewed document" dimensions.

It depends wether you consider the viewing parameters
as part *OF* the document, or something which is applied
*TO* the document.

It's not really a right/wrong thing. Both have their uses.
