Example 2 with COSWriter

use of com.tom_roush.pdfbox.pdfwriter.COSWriter in project PdfBox-Android by TomRoush.

the class PDDocument method saveIncrementalForExternalSigning.

 * <b>(This is a new feature for 2.0.3. The API for external signing might change based on feedback after release!)</b>

 * Save PDF incrementally without closing for external signature creation scenario. The general
 * sequence is:

 *    PDDocument pdDocument = ...;
 *    OutputStream outputStream = ...;
 *    SignatureOptions signatureOptions = ...; // options to specify fine tuned signature options or null for defaults
 *    PDSignature pdSignature = ...;
 *
 *    // add signature parameters to be used when creating signature dictionary
 *    pdDocument.addSignature(pdSignature, signatureOptions);
 *    // prepare PDF for signing and obtain helper class to be used
 *    ExternalSigningSupport externalSigningSupport = pdDocument.saveIncrementalForExternalSigning(outputStream);
 *    // get data to be signed
 *    InputStream dataToBeSigned = externalSigningSupport.getContent();
 *    // invoke signature service
 *    byte[] signature = sign(dataToBeSigned);
 *    // set resulted CMS signature
 *    externalSigningSupport.setSignature(signature);
 *
 *    // last step is to close the document
 *    pdDocument.close();
 * </pre>
 * <p>
 * Note that after calling this method, only {@code close()} method may invoked for
 * {@code PDDocument} instance and only AFTER {@link ExternalSigningSupport} instance is used.
 * </p>
 *

 * document is closed. It <i><b>must never</b></i> point to the source file
 * or that one will be harmed!
