I am trying to retrieve a File
or InputStream
instance from PDDocument
without saving a PDDocument
to the file system.
PDDocument doc= new PDDocument();
...
doc.save("D:\\document.pdf");
File f= new File("D:\\document.pdf");
Is there any method in PDFBox
which returns File
or InputStream
from an existing PDDocument
?
I solved it:
PDDocument doc=new PDDocument();
PDStream ps=new PDStream(doc);
InputStream is=ps.createInputStream();
I solve it in this way ( It's creating a file but in temporary-file directory ):
final PDDocument document = new PDDocument();
final File file = File.createTempFile(filename, ".pdf");
document.save(file);
and if you need
document.close();
What if you first create the outputstream
PDDocument doc= new PDDocument();
File f= new File("D:\\document.pdf");
FileOutputStream fOut = new FileOutputStream(f);
doc.save(fOut);
Take a look at this http://pdfbox.apache.org/apidocs/org/apache/pdfbox/pdmodel/PDDocument.html#save(java.io.OutputStream)

Obviously PDFBox cannot return a meaningful File
object without saving a PDDocument
to the file system .
It does not offer a method providing an InputStream
directly either but it is easy to write code around it that does. eg:
InputStream docInputStream = null;
try ( ByteArrayOutputStream baos = new ByteArrayOutputStream();
PDDocument doc = new PDDocument() )
{
[...]
doc.save(baos);
docInputStream = new ByteArrayInputStream(baos.toByteArray());
}
