Getting PDF page size information, converting from points to inches, centimeters, millimeters

// open PDF document
PDFImages pdfDoc = new PDFImages ("C:\\myfile.pdf", null);
 
// loop through pages
for (int count = 0; count < pdfDoc.getPageCount(); ++count)
{
 // this is the cropped page size in points at 72 dpi
 double pageWidth = pdfDoc.getDisplayWidth(count);
 double pageHeight = pdfDoc.getDisplayHeight(count);
