[reportlab-users] Adding annotations to a pdf

[pianoslum]

Hi Robin,

thanks for your quick answer.
Actually I modified a SO example (), here's my code:

from PyPDF2 import PdfFileWriter, PdfFileReader
import io
from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import letter

packet = io.BytesIO()
# create a new PDF with Reportlab
can = canvas.Canvas(packet, pagesize=letter)
can.drawString(10, 100, "Hello world")
#can.highlightAnnotation("TEST", Rect=[1, 1, 1, 1], relative=1)
can.save()

#move to the beginning of the StringIO buffer
packet.seek(0)
new_pdf = PdfFileReader(packet)
# read your existing PDF
existing_pdf = PdfFileReader(open("original.pdf", "rb"))
output = PdfFileWriter()
# add the "watermark" (which is the new pdf) on the existing page
page = existing_pdf.getPage(0)
page.mergePage(new_pdf.getPage(0))
output.addPage(page)
# finally, write "output" to a real file
outputStream = open("destination.pdf", "wb")
output.write(outputStream)
outputStream.close()

The drawString-call works as intended, but the highlightAnnotation 
results in the crash.

I tried your example (stripped it of some test code) and it results in 
the same crash. Does the example above work for you?

I'm on ArchLinux x64, python 3.7.1, evince 3.30.2, reportlab 3.5.12

Sorry, if I miss something :-)
Cheers!
