System.out.print("Width for Max Height  " + docInfo.getWidthForMaxHeight());
System.out.print("Max Page Height" + docInfo.getMaxPageHeight());
System.out.print("File size in bytes is " + docInfo.getSize());
System.out.print("Width of first page is " + docInfo.getPages().get(0).getWidth());
for(PageInfo page : docInfo.getPages()){
