Hi, i have need to modify pdf. I do query from oracle database and return lob datatype, how can i open this with function hummus.PDFRStreamForFile(param);

  const inStream = new hummus.PDFRStreamForFile(queryResult.blobData);
  const outStream = new hummus.PDFWStreamForFile('/home/davide/Doc/result.pdf');
  const pdfWriter = hummus.createWriterToModify(inStream, outStream);

  let pageModifier = new hummus.PDFPageModifier(pdfWriter, 0);
  pageModifier.startContext().getContext().writeText(
    'Test Text',
    75, 805,
    { font: pdfWriter.getFontForFile('/home/davide/doc/Couri.ttf'), size: 14, colorspace: 'gray', color: 0x00 }
  );

  pageModifier.endContext().writePage();
  pdfWriter.end();
  inStream.close(() => {
    console.log('inStream done');
  });
  outStream.close();
})
.catch(error =>{
  console.log("ERRORE", error);
})

Use function PDFRStreamForBuffer to load InStream variable.

  const inStream = new hummus.PDFRStreamForBuffer(buffer);
