Pyxif

To simplify exif manipulations with python. Writing, reading, and more... Pyxif isn't a wrapper. To everywhere with Python(function'thumbnail' depends on PIL or Pillow).

Functions

dump - converts dict to exif bytes
insert - inserts exif bytes to JPEG
load - get exif as dict from file
remove - removes exif from JPEG
thumbnail - resizes proportionally without loosing exif(depend on PIL or Pillow)
transplant - transplants exif to another JPEG

How to Use

# dump and insert
zeroth_ifd = {pyxif.ImageGroup.Make: "Canon",
              pyxif.ImageGroup.XResolution: (96, 1),
              pyxif.ImageGroup.YResolution: (96, 1),
              pyxif.ImageGroup.Software: "paint.net 4.0.3",
              }
exif_bytes = pyxif.dump(zeroth_ifd)
pyxif.insert(exif_bytes, "in.jpg")
# or
from PIL import Image
im = Image.open("in.jpg")
im.thumbnail((100, 100), Image.ANTIALIAS)
im.save(output_file, exif=exif_bytes)

# load
zeroth_dict, exif_dict, gps_dict = pyxif.load("in.jpg")

# remove
pyxif.remove("in.jpg")

# thumbnail
pyxif.thumbnail("in.jpg", "out.jpg", (80, 80))

# transplant
pyxif.transplant("exif_src.jpg", "image.jpg")

on GoogleAppEngine

jpg_data = self.request.get("jpeg")
output = io.BytesIO()

# insert
pyxif.insert(exif_bytes, jpg_data, output)

# load
zeroth_dict, exif_dict, gps_dict = pyxif.load(jpg_data)

# remove
pyxif.remove(jpg_data, output)

# thumbnail
pyxif.thumbnail(jpg_data, output, (80, 80))

# transplant
pyxif.transplant(jpg_data1, jpg_data2, output)

Depends on

Function "thumbnail" depends on PIL, or Pillow(Tested on Pillow 2.5.3). Others don't depend on any 3rd module.

Environment

Checked on Python 2.7, 3.3 and 3.4.
