PNG Renderer

For constructing a zip file of png images. I created this package as I had many plots associated from the output of a plotting script and wanted to keep them together. Similar to matplotlib.backends.PdfPages I wanted to associate the images, but using the png format, so I chose to zip the collection of images. I wanted png images as they contained large amounts of data which created extremely large pdf files.

Example usage

import matplotlib.pyplot as plt
from pngrenderer import PNGRenderer

fig = plt.figure()

plt.plot(...)

# Save the resulting image(s) to "out.zip"
renderer = PNGRenderer("out")

# Save the first png image
renderer.savefig("first.png")

# Alternatively call .save_page
# renderer.save_page("first.png")

# Render the zip file to disk
renderer.render()

# Alternatively use the context manager
from pngrenderer import png_render

with png_render("out") as renderer:
    renderer.savefig()

# The context manager calls the `render` method

Requirements and installation

This package requires matplotlib, but no other packages

Installation: pip install git+https://github.com/mindriot101/pngrenderer.git

If this package ever makes it onto pypi then probably the installation will be pip install matplotlib-pngrenderer.
