plutoprint 0.4.1

Paged HTML rendering library

PlutoPrint

PlutoPrint is a lightweight and easy-to-use Python library for generating high-quality PDFs and images directly from HTML or XML content. It is based on PlutoBook’s robust rendering engine and provides a simple API to convert your HTML into crisp PDF documents or vibrant image files. This makes it ideal for reports, invoices, or visual snapshots.

Installation

pip install plutoprint

PlutoPrint depends on PlutoBook. For faster installation, it is highly recommended to install PlutoBook and its dependencies manually beforehand. Otherwise, Meson will build them from source during installation, which can take significantly longer.

For Windows and Linux 64-bit users, PlutoPrint provides prebuilt binaries, so no additional setup is required.

Quick Usage

Generate a PDF from the command line with the installed plutoprint script:

plutoprint input.html output.pdf --size=A4

Generate PDF with Python

import plutoprint

book = plutoprint.Book(plutoprint.PAGE_SIZE_A4)
book.load_url("input.html")
book.write_to_pdf("output.pdf")

Generate PNG with Python

import plutoprint
import math

book = plutoprint.Book(media=plutoprint.MEDIA_TYPE_SCREEN)
book.load_html("<b>Hello World</b>", user_style="body { text-align: center }")

width = math.ceil(book.get_document_width())
height = math.ceil(book.get_document_height())

with plutoprint.ImageCanvas(width, height) as canvas:
   canvas.clear_surface(1, 1, 1)
   book.render_document(canvas)
   canvas.write_to_png("hello.png")

Generate Charts with Matplotlib

import plutoprint

import matplotlib.pyplot as plt
import urllib.parse
import io

class CustomResourceFetcher(plutoprint.ResourceFetcher):
    def fetch_url(self, url):
        if not url.startswith('chart:'):
            return super().fetch_url(url)
        values = [float(v) for v in urllib.parse.unquote(url[6:]).split(',')]
        labels = [chr(65 + i) for i in range(len(values))]

        plt.bar(labels, values)
        plt.title('Bar Chart')
        plt.xlabel('Labels')
        plt.ylabel('Values')

        buffer = io.BytesIO()
        plt.savefig(buffer, format='svg', transparent=True)

        return plutoprint.ResourceData(buffer.getvalue(), "image/svg+xml", "utf-8")

book = plutoprint.Book(plutoprint.PAGE_SIZE_A4.landscape(), plutoprint.PAGE_MARGINS_NONE)

book.custom_resource_fetcher = CustomResourceFetcher()

HTML_CONTENT = """
<div>
    <img src='chart:23,45,12,36,28,50'>
    <img src='chart:5,15,25,35,45'>
    <img src='chart:50,40,30,20,10'>
    <img src='chart:10,20,30,40,50,60,70'>
</div>
"""

USER_STYLE = """
div { display: flex; flex-wrap: wrap; justify-content: center; height: 98vh }
img { flex: 0 0 45%; height: 50%; background: #fff; border: 1px solid #ccc; }
body { background: #f7f7f7 }
"""

book.load_html(HTML_CONTENT, USER_STYLE)
book.write_to_png("charts.png")
book.write_to_pdf("charts.pdf")
