## 2. Add Watermark to PDF
### Open the watermark file
with io.open('./watermark.pdf', mode='rb') as watermark_file:
watermark = PdfFileReader(watermark_file)
### Open the output file
with io.open(merged_file_path, mode='wb') as merged_file:
### Start the PDF writer buffer
output = PdfFileWriter()
### Open the input file
with io.open(input_file_path, mode='rb') as input_file:
input_pdf = PdfFileReader(input_file)
page_count = input_pdf.getNumPages()
### Add watermark to every page
for page_number in range(page_count):
input_page = input_pdf.getPage(page_number)
input_page.mergePage(watermark.getPage(0))
output.addPage(input_page)
### Open the file stream to the output file and save the result
with io.open(merged_file_path, mode='wb') as merged_file:
#tmp_out = io.BytesIO()
#output.write(tmp_out)
#print(tmp_out.getvalue())
output.write(merged_file)
## 3. Clean files
