I have a simple function to extra some pages from a given pdf file to a new
file which runs fine, however I need to save the meta data in the new file
as well, if I open the original pdf file in a text editor I can see the meta
data in the first few lines:
%PDF-1.3
%âãÏÓ
1 0 obj

/Type /Catalog
/Pages 2 0 R

endobj
2 0 obj

However in the new generated file, if I open it in a text editor, the file
start with:
%PDF-1.4

... ...
MyMethod: (note it can extrat the pages OK in a pdf viewer, but xI need the
meta data as well which can be found using a text editor)
public static void extractPDFPage(String fromPath, int from, int to, String
toPath)
throws AptoEnclosingException
{
log.info("Start extracting pdf file ...");
try
{
PdfReader treader = new PdfReader(fromPath);
int n = treader.getNumberOfPages();
treader.close();
PdfReader reader = new PdfReader(fromPath);
if ((from < 1) || (n < to))
throw new IOException("Required pages
are out of range!");
com.lowagie.text.Document document = new
com.lowagie.text.Document(
reader.getPageSizeWithRotation(1));
File tempFile = new File(toPath);
if (tempFile.exists())
tempFile.delete();
FileOutputStream outputFile = new
FileOutputStream(tempFile);
PdfSmartCopy copy = new PdfSmartCopy(document,
outputFile);
document.open();
//I don't think meta[] is getting anything
byte meta[] = reader.getMetadata();
PdfStamper stamp = new PdfStamper(reader,
outputFile);
for (int i = from; i<to; i++)
{
PdfImportedPage page =
copy.getImportedPage(reader,i);
copy.addPage(page);
}
stamp.setXmpMetadata(meta);
document.close();
reader.close();
log.info("Extracting pdf file done!");
}
catch (IOException e)
{
throw new AptoEnclosingException(e);
}
catch (DocumentException e)
{
throw new AptoEnclosingException(e);
}
}
Many thanks for your help!!!
