Introduction to the basic functions and characteristics of the XHTML2PDF library in Python
XHTML2PDF is a library that converts HTML/XHTML and CSS into PDF files in Python.It provides a convenient way to convert the content of the webpage into printed PDF files, which can be used to generate various types of files such as reports, documents, e -books, etc.
XHTML2PDF has the following basic functions and characteristics:
1. Support of HTML and CSS: XHTML2PDF can process web content containing HTML and CSS and convert it to PDF files.It follows the W3C standard and can normalize and render complex web layouts and styles.
2. Support custom style: Users can customize the generated PDF files through the CSS style table, including fonts, colors, typesetting and other style attributes.
3. Support Chinese: XHTML2PDF has a very friendly processing of Chinese content, can render Chinese characters normally, and support Unicode encoding, which can generate PDF files containing Chinese content.
4. Support page layout adjustment: The user can adjust the page layout of the generated PDF file by setting parameters such as page size, border distance, and header.
5. You can call it through command lines or Python scripts: XHTML2PDF can be used as an independent command line tool, or it can be embedded in the Python script for calls, and more flexible customization and expansion through the API.
Below is a simple example code that demonstrates how to use XHTML2PDF to convert HTML content to PDF file:
python
from xhtml2pdf import pisa
html = """
<!DOCTYPE html>
<html>
<head>
<style>
h1 {
color: #008000;
}
</style>
</head>
<body>
<h1>Hello, World!</h1>
<p>This is a test PDF generated using xhtml2pdf.</p>
</body>
</html>
"""
pdf_file = open("test.pdf", "w+b")
pisa_status = pisa.CreatePDF(html, dest=pdf_file)
pdf_file.close()
if pisa_status.err:
print("Failed to generate PDF: %s" % pisa_status.err)
else:
print("PDF generated successfully!")
In this example, a simple HTML content is first defined, and the Pisa.CreatePDF function is used to convert it to a PDF file.The generated PDF file will contain a green title and a text content.In the end, the generated PDF file is stored to a file named Test.pdf.
The above is the basic function and characteristic introduction of the XHTML2PDF library. It provides users with a convenient and powerful tool that can meet the needs of all kinds of web pages into PDF files.
