I've read the documentation and the examples but I'm having a hard time putting it all together. I'm just trying to take a test pdf file and then convert it to a byte array then take the byte array and convert it back into a pdf file then create the pdf file onto disk.
It probably doesn't help much, but this is what I've got so far:
package javaapplication1;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import org.apache.pdfbox.cos.COSStream;
import org.apache.pdfbox.exceptions.COSVisitorException;
import org.apache.pdfbox.pdmodel.PDDocument;
public class JavaApplication1 {
private COSStream stream;
public static void main(String[] args) {
try {
PDDocument in = PDDocument.load("C:\\Users\\Me\\Desktop\\JavaApplication1\\in\\Test.pdf");
byte[] pdfbytes = toByteArray(in);
PDDocument out;
} catch (Exception e) {
System.out.println(e);
}
}
private static byte[] toByteArray(PDDocument pdDoc) throws IOException, COSVisitorException {
ByteArrayOutputStream out = new ByteArrayOutputStream();
try {
pdDoc.save(out);
pdDoc.close();
} catch (Exception ex) {
System.out.println(ex);
}
return out.toByteArray();
}
public void PDStream(PDDocument document) {
stream = new COSStream(document.getDocument().getScratchFile());
}
}
You can use Apache commons , which is essential in any java project IMO.
Then you can use FileUtils 's readFileToByteArray(File file)
and writeByteArrayToFile(File file, byte[] data)
.
(here is commons-io, which is where FileUtils is: http://commons.apache.org/proper/commons-io/download_io.cgi )
For example, I just tried this here and it worked beautifully.
try {
File file = new File("/example/path/contract.pdf");
byte[] array = FileUtils.readFileToByteArray(file);
FileUtils.writeByteArrayToFile(new File("/example/path/contract2.pdf"), array);
} catch (IOException e) {
e.printStackTrace();
}
