Converting a Python Dummy PDF to Bytes Using Python

To resolve the issue of getting a PDF file with blank pages, you can modify your args as follows: Instead of saving the string representation of the PDF to a file, try outputting the stream to a file. For converting a docx file to a PDF, you can use Solution 2 which involves installing a package. If there are any mistakes in my understanding, kindly let me know so that I can correct them.

Convert DOCX Bytestream to PDF Bytestream Python

At present, I possess a software that utilizes the python-docx framework to produce a document in .docx format.

After I finish constructing the .docx file, I store it in a Bytestream.

file_stream = io.BytesIO() document.save(file_stream) file_stream.seek(0) 

To obtain a PDF version of word document, I have explored various conversion libraries, including docx2pdf, as well as the option of converting it manually with the help of comtypes.

import sys import os import comtypes.client wdFormatPDF = 17 in_file = "Input_file_path.docx" out_file = "output_file_path.pdf" word = comtypes.client.CreateObject('Word.Application') doc = word.Documents.Open(in_file) doc.SaveAs(out_file, FileFormat=wdFormatPDF) doc.Close() word.Quit() 

The issue at hand is that I am required to perform the conversion solely in the memory and not store either the DOCX or PDF file on the computer. Thus far, all the converters I have come across necessitate a file path to the physical document on the machine, which is not available to me.

How can I transform the DOCX filestream to a PDF stream without saving it on disk?

Although it may seem a bit complicated, this approach operates entirely in memory, and it allows you to incorporate personalized CSS to design the ultimate file. You can utilize mammoth to change the DOCX bytestream into HTML, producing the HTML to PDF using pdfkit.

# create a dummy docx file from docx import Document document = Document() document.add_paragraph('Lorem ipsum dolor sit amet.') # create a bytestream import io file_stream = io.BytesIO() document.save(file_stream) file_stream.seek(0) # convert the docx to html import mammoth result = mammoth.convert_to_html(file_stream) # >>> result.value # >>> '
Lorem ipsum dolor sit amet.
' # convert html to pdf import pdfkit pdf = pdfkit.from_string(result.value) 

To save the stream to a file, simply execute.

with open('test.pdf','wb') as file: file.write(pdf) 

To transfer the convert docx file to pdf file, you can use the following steps.

from docx2pdf import convert convert("input.docx") convert("input.docx", "output.pdf") convert("my_docx_folder/") 

If I have made an error, kindly let me know so I can rectify it. Thank you.

What are the arguments for converting a double-up pdf page into a, If you read the text its says «Device pdfwrite requires an output file but no file was specified». So that tells you that -o was ignored,

What are the arguments for converting a double-up pdf page into a one column pdf page using ghostscript

To convert a double-up pdf page to a single column pdf page, I require the necessary ghostscript arguments.

the input +--------+-------+ | | | | | | | | | | 1 | 2 | | | | | | | +--------+--------+ the output +-------+ | | | 1 | | | | | | | | | +--------+ +-------+ | | | 2 | | | | | | | | | +--------+ 

Based on the contents of post1 and post2, I developed this code.

import sys import locale import ghostscript args = [ "-ooutput.pdf", "-sDEVICE=pdfwrite", "-g2807x5950" "-fpdfFile.pdf" ] # arguments have to be bytes, encode them encoding = locale.getpreferredencoding() args = [a.encode(encoding) for a in args] ghostscript.Ghostscript(*args) 

I was anticipating a PDF file comprising of 2 pages, but an fatal error error was encountered.

An update has been made to include the error message, which can be found in the image description section.

The text indicates that the «Device pdfwrite» necessitates an output file, but none was specified, resulting in the disregard of the -o instruction or some other issue with it.

It appears that you may be utilizing the Ghostscript DLL instead of creating a new process. In such a case, it is necessary to assign a false value to argv[0]. This is due to the fact that, when executing a C program, argv[0] represents the name of the executable. Therefore, the argument processing omits the first element of the arguments array.

The Ghostscript documentation provides coverage on this topic.

It appears that there could be a missing period in argument list, although I am not entirely certain and could be mistaken.

It’s likely that you will have to modify your arguments to a format similar to this:

args = [ "MyApp", "-o output.pdf", "-sDEVICE=pdfwrite", "-g2807x5950", "-fpdfFile.pdf" ]

Save response.text as PDF

My concern is that even though I possess a string that reflects a PDF, attempting to store it as a PDF file leads to a blank page.

Despite my attempts to save the bytes of the string as a file using ‘utf-8’ encoding, the problem persists.

import requests url = 'https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf' response = requests.get(url) with open('example.pdf', 'w') as f: f.write(response.text) 

While I understand that preserving response.content is the proper method to save the PDF in the given scenario, my unique situation only permits me to utilize the string.

One possible solution is to employ the fpdf package.

from fpdf import FPDF pdf = FPDF() pdf.add_page() pdf.set_font("Arial", size=12) pdf.cell(200, 10, txt=response.text, ln=1, align="C") pdf.output("output.pdf") 

The source for the information can be found at the following URL: http://www.blog.pythonlibrary.org/2018/06/05/creating-pdfs which discusses how to use PyFPDF and Python together.

Refer to the provided documentation at https://pyfpdf.readthedocs.io/en/latest/index.html for further information.

From a link I posted before:

I opted for it to convert my HTML files into PDF format, using a two-step process within my designated stack of Python Pyramid.

Utilizing mako templates on the server-side, the desired style and markup for pdf document can be achieved. By invoking the pdfkit.from_string(. ) method and passing the rendered html, a PDF document will be generated that supports images and styling.

You can install it as follows :

To use it on Ubuntu, the installation of wkhtmltopdf is required.

import pdftotext # Load your PDF with open(r'C:\Users\Mahsa\Desktop\stack\dummy.pdf', "rb") as f: pdf = pdftotext.PDF(f) 

from fpdf import FPDF pdf = FPDF() pdf.add_page() pdf.set_xy(0, 0) pdf.set_font('arial', 'B', 13.0) pdf.cell(ln=0, h=5.0, align='L', w=0, txt="Your text from ", border=0) pdf.output(r'D:\pdf\test.pdf', 'F')
