I have implemented this code:
Document ficha = new Document("D:/input.docx");
ByteArrayOutputStream pdfOutputStream = new ByteArrayOutputStream();
ficha.save(pdfOutputStream, SaveFormat.DOCX);
byte[] test = pdfOutputStream.toByteArray();
FileOutputStream file = new FileOutputStream("D:/output.docx");
file.write(test);
file.close();
Why I'm getting a empty line in the beginning of the output.docx? It's a simple code but it shows my problem.
