Zdravim, ako embedded developer s tymto nemam moc skusenosti chcem sa spytat skusenejsich. Mam 2 pdf subory:
fa.pdf je vektorovy formular, chcem zachovat ako je (snazil som sa ho importnut ako text do svg (inkscape scribus, libreoffice) ale vzdy mi to rozbilo formatovanie)
peciatka.pdf je bitmapa - nascanovana peciatka
No a chcel by som este doplnit nejake veci rucne z databazy (vid Hello world" nizsie). Pouzil som reportlab. 
Existuje nejaky WYSIWYG editor kde by som vizualne umiestnil text na pdf a ten by mi vyexportoval tieto can.drawString(100, 100, "Hello world") commandy ?
 
import ioimport PyPDF2
from reportlab.lib import fonts
from reportlab.lib.pagesizes import *
from reportlab.pdfbase import pdfmetrics
from reportlab.pdfbase import ttfonts
from reportlab.pdfgen import canvas
 
# Register the Ubuntu font
pdfmetrics.registerFont(ttfonts.TTFont('Ubuntu', 'UbuntuMono-B.ttf'))
 
# Register the Ubuntu font
fonts.addMapping('Ubuntu', 0, 0, 'UbuntuMono-B.ttf')
 
# Get the list of registered font names
font_names = pdfmetrics.getRegisteredFontNames()
 
packet = io.BytesIO()
can = canvas.Canvas(packet, pagesize=A4)
can.setFont('Ubuntu', 10)
can.drawString(0, 0, "Hello world")
can.drawString(100, 100, "Hello world")
can.save()
 
# move to the beginning of the StringIO buffer
packet.seek(0)
 
background = PyPDF2.PdfReader(open("fa.pdf", "rb")).pages[0]
foreground = PyPDF2.PdfReader(open("peciatka.pdf", "rb")).pages[0]
hello = PyPDF2.PdfReader(packet).pages[0]
 
# merge the first two pages
background.merge_page(foreground)
background.merge_page(hello)
 
# add all pages to a writer
writer = PyPDF2.PdfWriter()
writer.add_page(background)
writer.write(open("modified.pdf", "wb")
