Optimizing fpdf for Bulk Text-to-PDF Conversion

Postby NariusFalk » Sun Nov 26, 2023 7:18 pm

Hello !

I'm facing a rather intricate challenge in converting text files to PDF. Using the fpdf library, I'm trying to optimize the process for converting large volumes of textual data. I've read an interesting article on the subject ( https://astuce2geek.fr/comment-convertir-un-fichier-en-pdf-avec-python/ ), but I wonder if anyone has experimented with specific optimization techniques?

My question is twofold: First, how can we efficiently manage memory when converting very large text files? Second, are there methods to speed up the conversion process while maintaining the formatting and quality of the final PDF?

Feedback, tips, or code suggestions would be extremely helpful. Thanks in advance for your help!

Code: Select all

import os
from fpdf import FPDF

class MyPDF(FPDF):
    # Personnaliser l'en-tête
    def header(self):
        self.set_font('Arial', 'I', 8)
        self.cell(0, 10, 'Ton En-tête Personnalisé', 0, 0, 'C')

    # Personnaliser le pied de page
    def footer(self):
        self.set_font('Arial', 'I', 8)
        self.cell(0, 10, 'Page %s' % self.page_no(), 0, 0, 'C')

    # Ajouter un titre
    def add_title(self, title):
        self.set_xy(10, 20)  # Augmente la position y pour éviter la superposition
        self.set_font('Arial', 'B', 16)
        self.cell(190, 10, title, 0, 1, 'C')

# Fonction pour convertir un seul fichier texte en PDF
def txt_to_pdf(file_path, output_path):
    pdf = MyPDF()
    pdf.set_font("Arial", size=12)

    # Ajouter un titre
    pdf.add_title("Mon Titre Stylé")

    # Ajouter une image
    pdf.image('image/image.jpg', x=10, y=100, w=100)

    # Ouvrir le fichier texte en mode lecture
    with open(file_path, 'r') as file:
        for line in file:
            pdf.cell(200, 10, txt=line, ln=True, align='L')

    # Sauvegarder le PDF

# Nouvelle fonction pour traiter plusieurs fichiers
def convert_multiple_txt_to_pdf(folder_path, output_folder):
    for filename in os.listdir(folder_path):
        if filename.endswith(".txt"):
            file_path = os.path.join(folder_path, filename)
            output_path = os.path.join(output_folder, filename.replace(".txt", ".pdf"))
            txt_to_pdf(file_path, output_path)

# Appel de la fonction pour un dossier spécifique
convert_multiple_txt_to_pdf("dossier_textes", "dossier_pdfs")
