EXIF-Stream is a library to perform stream parsing of a JPEG/EXIF image.
The majority of this code was developed following an excellent write up of the file format from here.
The project is not quite complete and is lacking both in tests and functionality. Consider it to be a very early version.
Here's a sample program using the stream parser to retrieve EXIF tags from a photo in python:
from exifstream import stream import sys f = open(sys.argv, 'rb') s = stream.StreamProcessor() while True: chunk = f.read(100) if not chunk: break s.process(chunk) for tag in s.tags: print tag
