Hi,
I would like to store the pdf in ByteArrayOutputStream (which is later will
be saved in the DB). Im confused what baos I will be saved, due to some
repetetive page. This is my code:
PdfReader reader = new
PdfReader(context.getResourceAsStream("//file"));
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PdfStamper stamper = new PdfStamper(reader, baos);
Properties props = getSARFormProperties("mappingFile");
AcroFields form = stamper.getAcroFields();
Iterator<SarSubjectDTO> assocSubjects = null;
if (formData.getSubjects() != null && formData.getSubjects().size()
> 0) {
assocSubjects = formData.getSubjects().iterator();
SarSubjectDTO subject = assocSubjects.next();
fillSubjectInfoSection(props, form, subject);
}
else{
form.setField(props.getProperty(SUBJECT_INFO_UNAVAILABLE),"Yes");
}
stamper.setFormFlattening(true);
stamper.close();
reader = new PdfReader(baos.toByteArray());
Document document = new Document(reader.getPageSizeWithRotation(1));
PdfCopy writer = new PdfCopy(document, response.getOutputStream());
document.open();
writer.addPage(writer.getImportedPage(reader, 1));
if (assocSubjects != null) {
/*
* Iterate over remaining associated subjects: for each one
create a separate
* form in memory and copy Page 1 to the original final
document.
*/
while (assocSubjects.hasNext()) {
SarSubjectDTO subject = assocSubjects.next();
PdfReader reader2 = new
PdfReader(context.getResourceAsStream("//file"));
baos = new ByteArrayOutputStream();
stamper = new PdfStamper(reader2, baos);
form = stamper.getAcroFields();
fillSubjectInfoSection(props, form, subject);
stamper.setFormFlattening(true);
stamper.close();
reader2 = new PdfReader(baos.toByteArray());
writer.addPage(writer.getImportedPage(reader2, 1));
}
writer.addPage(writer.getImportedPage(reader, 2));
}
Can I save the file using,
ServletOutputStream out = response.getOutputStream();
baos.writeTo(out); // is this correct??
byte[] pdfByte = baos.toByteArray();
System.out.println("file Size:"+pdfByte.length);
Is this correct? Why is the pdfByte.length smaller than file size in windows
explorer when I saved it in the local machine? Please advice.
