A python module to deal with APNG file.

A python module to deal with APNG file.

Features

• Merge multiple images into one APNG file. (It use Pillow to convert image into PNG format)

• Read APNG file and extract each frames into PNG file.

• It doesn’t do any optimization but only concat the images. This might be changed in the future.

Dependencies

• Pillow - Optional. You can still use pyAPNG without PIL but it can only read PNG files.

Install

pip install apng

Usage

Convert a series of images into APNG animation:

from apng import APNG

APNG.from_files(["1.jpg", "2.jpg", "3.jpg"], delay=100).save("result.png")

Use different delay:

from apng import APNG

files = [
    ("1.jpg", 100),
    ("2.jpg", 200),
    ("3.jpg", 300)
]

im = APNG()
for file, delay in files:
    im.append(file, delay=delay)
im.save("result.png")

Extract frames from APNG file:

from apng import APNG

im = APNG.open("animation.png")
i = 0
for png, control in im.frames:
    png.save("{i}.png".format(i=i))
    i += 1
