Comment puis-je placer une image sur un fichier PDF existant à un emplacement de coordonnées spécifique. Le pdf représente une feuille de dessin d'une page. L'image sera mise à l'échelle. Je vérifie ReportLab mais je ne trouve pas la réponse. Merci.
from pyPdf import PdfFileWriter, PdfFileReader
output = PdfFileWriter()
input1 = PdfFileReader(file("document1.pdf", "rb"))
watermark = PdfFileReader(file("watermark.pdf", "rb"))
input1.mergePage(watermark.getPage(0))
# finally, write "output" to document-output.pdf
outputStream = file("document-output.pdf", "wb")
output.write(input1)
outputStream.close()
Je pense que c'est comme watermark
, voir le manuel pour une meilleure idée
Cela fait 5 ans, je pense que ces réponses ont besoin d’être approfondies. Voici une solution complète.
Ce qui suit est testé avec Python 2.7
Installer des dépendances
pip install reportlab
pip install pypdf2
Faire la magie
from reportlab.pdfgen import canvas
from PyPDF2 import PdfFileWriter, PdfFileReader
# Create the watermark from an image
c = canvas.Canvas('watermark.pdf')
# Draw the image at x, y. I positioned the x,y to be where i like here
c.drawImage('test.png', 15, 720)
# Add some custom text for good measure
c.drawString(15, 720,"Hello World")
c.save()
# Get the watermark file you just created
watermark = PdfFileReader(open("watermark.pdf", "rb"))
# Get our files ready
output_file = PdfFileWriter()
input_file = PdfFileReader(open("test2.pdf", "rb"))
# Number of pages in input document
page_count = input_file.getNumPages()
# Go through all the input file pages to add a watermark to them
for page_number in range(page_count):
print "Watermarking page {} of {}".format(page_number, page_count)
# merge the watermark with the page
input_page = input_file.getPage(page_number)
input_page.mergePage(watermark.getPage(0))
# add page from input file to output document
output_file.addPage(input_page)
# finally, write "output" to document-output.pdf
with open("document-output.pdf", "wb") as outputStream:
output_file.write(outputStream)

J'ai combiné ReportLab (http://www.reportlab.com/software/opensource/rl-toolkit/download/) et pyPDF (http://pybrary.net/pyPdf/) pour insérer une image directement sans avoir à générer le PDF à l'avant:
from pyPdf import PdfFileWriter, PdfFileReader
from reportlab.pdfgen import canvas
from StringIO import StringIO
# Using ReportLab to insert image into PDF
imgTemp = StringIO()
imgDoc = canvas.Canvas(imgTemp)
# Draw image on Canvas and save PDF in buffer
imgPath = "path/to/img.png"
imgDoc.drawImage(imgPath, 399, 760, 160, 160) ## at (399,760) with size 160x160
imgDoc.save()
# Use PyPDF to merge the image-PDF into the template
page = PdfFileReader(file("document.pdf","rb")).getPage(0)
overlay = PdfFileReader(StringIO(imgTemp.getvalue())).getPage(0)
page.mergePage(overlay)
#Save the result
output = PdfFileWriter()
output.addPage(page)
output.write(file("output.pdf","w"))
Merci aux réponses précédentes. Mon chemin avec python3.4
# -*- coding: utf-8 -*-
from io import BytesIO
from PyPDF2 import PdfFileWriter, PdfFileReader
from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import A4
def gen_pdf():
# there are 66 slides (1.jpg, 2.jpg, 3.jpg...)
path = 'slades/{0}.jpg'
pdf = PdfFileWriter()
for num in range(1, 67): # for each slide
# Using ReportLab Canvas to insert image into PDF
imgTemp = BytesIO()
imgDoc = canvas.Canvas(imgTemp, pagesize=A4)
# Draw image on Canvas and save PDF in buffer
imgDoc.drawImage(path.format(num), -25, -45)
# x, y - start position
# in my case -25, -45 needed
imgDoc.save()
# Use PyPDF to merge the image-PDF into the template
pdf.addPage(PdfFileReader(BytesIO(imgTemp.getvalue())).getPage(0))
pdf.write(open("output.pdf","wb"))
if __== '__main__':
gen_pdf()
C'est ce qui a fonctionné pour moi
from PyPDF2 import PdfFileWriter, PdfFileReader
def watermarks(temp, watermar,new_file):
template = PdfFileReader(open(temp, 'rb'))
wpdf = PdfFileReader(open(watermar, 'rb'))
watermark = wpdf.getPage(0)
for i in xrange(template.getNumPages()):
page = template.getPage(i)
page.mergePage(watermark)
output.addPage(page)
with open(new_file, 'wb') as f:
output.write(f)
C'est assez facile à faire avec PyMuPDF sans fusionner deux PDF:
import fitz
src_pdf_filename = 'source.pdf'
dst_pdf_filename = 'destination.pdf'
img_filename = 'barcode.jpg'
# http://pymupdf.readthedocs.io/en/latest/rect/
# Set position and size according to your needs
img_rect = fitz.Rect(100, 100, 120, 120)
document = fitz.open(src_pdf_filename)
# We'll put image on first page only but you could put it elsewhere
page = document[0]
page.insertImage(img_rect, filename=img_filename)
# See http://pymupdf.readthedocs.io/en/latest/document/#Document.save and
# http://pymupdf.readthedocs.io/en/latest/document/#Document.saveIncr for
# additional parameters, especially if you want to overwrite existing PDF
# instead of writing new PDF
document.save(dst_pdf_filename)
document.close()
