Use Python to convert PDF and SVG

SVG (Scalable Vector Graphics) and PDF (Portable Document Format) are two common and widely used file formats. SVG is an XML-based vector graphics format, mainly used for web graphics and illustrations. It has the characteristics of scalability and is suitable for high-quality, resolution independent graphic display. PDF is a general file format that is widely used in document storage and sharing, supports text, images and vector graphics, and has the advantages of high fidelity and cross-platform. In order to meet the application needs in different scenarios, it is sometimes necessary to convert each other between SVG and PDF.

This article will introduce in detail how to use Python to implement mutual conversion between SVG and PDF, and provide specific code examples and implementation steps.

  • Convert SVG to PDF using Python
  • Add SVG to an existing PDF using Python
  • Convert PDF to SVG using Python
  • Convert a specific page of a PDF to SVG using Python

Usage Tools

To implement mutual conversion between PDF and SVG in Python, you can use for Pythonlibrary. This library is mainly used to generate and process PDF documents in Python applications, supports converting PDFs and SVGs, and also supports converting PDFs to other formats, such as pictures, Word and Excel.

Install

Before you start, you need to install the library first. Run the following command to install:

pip install

Convert SVG to PDF using Python

For Python provides a () method that supports loading SVG vector images and converting them into PDF pages. After that, use the () method to save the result document as a PDF file. The specific steps are as follows:

  • Initializes an instance of the PdfDocument class.
  • Use the() method to load the SVG vector image and convert it to a PDF page.
  • Use the() method to save the result document as a PDF file.

Implementation code:

from  import *
from  import *
 
# Create a PdfDocument objectdoc = PdfDocument()
# Load the SVG vector and convert it to a PDF page("Test.svg")
 
# Save the result document as a PDF file("Svg", )
# Close the PdfDocument object()

Add SVG to an existing PDF using Python

In some cases, you might want to insert an SVG vector into an existing PDF document instead of creating a brand new PDF file. The following steps show how to add an SVG vector to a specific location in a PDF:

  • Initializes an instance of the PdfDocument class.
  • Use the() method to load the SVG vector image and convert it to a PDF page.
  • Use the [0].CreateTemplate() method to convert the PDF page into a reusable template.
  • Initialize the PdfDocument instance.
  • Use the() method to load an existing PDF document.
  • Use the [index].() method to draw the template to a specified location on a PDF specific page. The index is the index of the PDF page and is calculated from 0.
  • Use the() method to save the result document as a PDF file.

Implementation code:

from  import *
from  import *
 
# Create a PdfDocument objectdoc = PdfDocument()
# Load the SVG vector and convert it to a PDF page("Test.svg")
 
# Convert this PDF page to a reusable templatetemplate = [0].CreateTemplate()
 
# Create another PdfDocument objectnewDoc = PdfDocument()
# Load the target PDF file("Example.pdf")
 
# Draw the template on the first page of the target PDF[0].(template, PointF(150.0, 120.0))
 
# Save the result document as a PDF file("Insert Svg to", )
# Close the PdfDocument object()
()

Convert PDF to SVG using Python

Because SVG can be embedded directly into HTML and displayed as part of a web page. Therefore, converting PDF to SVG can easily embed the PDF's content into a webpage to display.

With for Python, you can convert all pages of a PDF file into SVG graphics, and in addition, you can control the size of the generated SVG graphics. The specific steps are as follows:

  • Initializes an instance of the PdfDocument class.
  • Use the () method to load the target PDF document.
  • Use the() method to set the width and height of the output SVG figure.
  • Use the () method to save each page of the PDF document as SVG graphics separately.

Implementation code:

from  import *
from  import *
 
# Create a PdfDocument objectdoc = PdfDocument()
# Load the target PDF file("Example.pdf")
 
# Set the width and height of the output SVG graphics(600.0, 600.0)
 
# Save each page of the PDF file as an SVG graphic("Pdf to", )
# Close the PdfDocument object()

Convert a specific page of a PDF to SVG using Python

In addition to converting all pages of a PDF file to SVG, you can also convert a page or a certain range of pages in a PDF file to SVG. The specific steps are as follows:

  • Initializes an instance of the PdfDocument class.
  • Use the () method to load the target PDF document.
  • Pass the index of the start PDF page and the end PDF page (calculated from 0) into the() method to save a specific page or a page within a certain range of the PDF document as an SVG graphic.

Implementation code:

from  import *
from  import *
 
# Create a PdfDocument objectdoc = PdfDocument()
# Load the target PDF file("Example.pdf")
 
# Convert pages 3-4 of a PDF file to SVG graphics("Special page transfer", 2, 3, )
# Close the PdfDocument object()
