plutoprint 0.6.0

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("hello.html")

# Export the entire document to PDF
book.write_to_pdf("hello.pdf")

# Export pages 2 to 15 (inclusive) in order
book.write_to_pdf("hello-range.pdf", 2, 15, 1)

# Export pages 15 to 2 (inclusive) in reverse order
book.write_to_pdf("hello-reverse.pdf", 15, 2, -1)

# Render pages manually with PDFCanvas (in reverse order)
with plutoprint.PDFCanvas("hello-canvas.pdf", book.get_page_size()) as canvas:
   canvas.scale(plutoprint.UNITS_PX, plutoprint.UNITS_PX)
   for page_index in range(book.get_page_count() - 1, -1, -1):
      canvas.set_size(book.get_page_size_at(page_index))
      book.render_page(canvas, page_index)
      canvas.show_page()

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 }")

# Outputs an image at the document’s natural size
book.write_to_png("hello.png")

# Outputs a 320px wide image with auto-scaled height
book.write_to_png("hello-width.png", width=320)

# Outputs a 240px tall image with auto-scaled width
book.write_to_png("hello-height.png", height=240)

# Outputs an 800×200 pixels image (may stretch/squish content)
book.write_to_png("hello-fixed.png", 800, 200)

# Get the natural document size
width = math.ceil(book.get_document_width())
height = math.ceil(book.get_document_height())

# Outputs a high-resolution 5x scaled image
book.write_to_png("hello-scaled.png", width * 5, height * 5)

# Render manually on a canvas with white background
with plutoprint.ImageCanvas(width, height) as canvas:
   canvas.clear_surface(1, 1, 1)
   book.render_document(canvas)
   canvas.write_to_png("hello-canvas.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")
