We used the examples to create a pdf merge program. We have a one-page PDF,
26Mb in size that contains an image. It is taking 7-8 minutes to merge this
PDF. We have written a tiny java app that demonstrates the problem. We
stripped the test app down so that it is only processing one input file so
that it is now really only "merging" one PDF into a new PDF. So... the app
is only processing a one-page PDF (albeit big pdf) and it is taking 7-8
minutes to complete. Any help would be GREATLY appreciated to determine
why it is taking this long and whether there is any way to fix this.
The input PDF can be found at: http://home.fuse.net/mikebrungs/test.pdf
and the source code is shown below:
import java.io.File;
import java.io.FileOutputStream;
import com.lowagie.text.Document;
import com.lowagie.text.pdf.PdfCopy;
import com.lowagie.text.pdf.PdfImportedPage;
import com.lowagie.text.pdf.PdfReader;
import java.util.Date;
public class PdfTest
{
public static void main(String[] args)
{
try
{
// input file
File pdfFile = new File(args[0]);
// copied file being created
File outFile = new File(args[0] + ".Copied.pdf");
System.out.println("Input file is: " + args[0]);
System.out.println("Output file is: " + args[0] + ".Copied.pdf");
System.out.println("starting at: " + new Date().toString());
PdfReader reader = new PdfReader(pdfFile.getPath());
reader.consolidateNamedDestinations();
int numPages = reader.getNumberOfPages();
Document document = new
Document(reader.getPageSizeWithRotation(1));
PdfCopy writer = new PdfCopy(document, new
FileOutputStream(outFile.getPath()));
document.open();
PdfImportedPage page;
for (int j = 1; j <= numPages; j++)
{
page = writer.getImportedPage(reader, j);
writer.addPage(page);
}
reader.close();
writer.close();
writer.freeReader(reader);
System.out.println("finishing at: " + new Date().toString());
}
catch (Exception t)
{
t.printStackTrace();
}
}
}
