py3exiv2's Introduction

py3exiv2
*******

Welcome to py3exiv2, a python 3 binding to exiv2 (http://exiv2.org/), the C++
library for manipulation of EXIF, IPTC and XMP image metadata.
It is a python 3 module that allows your python scripts to read and write
metadata (EXIF, IPTC, XMP, thumbnails) embedded in image files
(JPEG, TIFF, ...).

Point your browser to http://exiv2.org/metadata.html for the complete metadata
tag reference.


Build dependencies
==================

py3exiv2 depends on the following libraries:

 * python (≥ 3.2)
 * boost.python3 (http://www.boost.org/libs/python/doc/index.html)
 * exiv2 (http://www.exiv2.org/)

Some examples in src/ use PyGTK (http://www.pygtk.org/) and PyQt
(http://www.riverbankcomputing.co.uk/software/pyqt/) to display image previews,
those are optional dependencies.

This is a typical list of build dependencies for a Debian/Ubuntu system:

 * python-all-dev (≥ 3.2)
 * libexiv2-dev (≥ 0.20)
 * libboost-python-dev (≥ 1.48)
 * g++


Building and installing
=======================

To build and install the library, while in the top-level directory
(e.g. '~/dev/p3yexiv2', which should contain a file named 'configure.py'),
run the following commands:

 $ python3 configure.py     # To chek your environment and write the Makefile
 $ ./build.sh               # To compile the lib
 $ ./build.sh -i            # as administrator to install all files

You can run configure.py with the following arguments:
    -h                  show the help message and exit
    --libboost=FILE     where FILE is the full path of libboost-python3
                        e.g. `/usr/lib/x86_64-linux-gnu/libboost_python-py34.so`

The result of the build is a dynamic library, libexiv2python.so, in the build/
directory. This is the low-level binding. It is in turn used in a higher level
module, pyexiv2.
The `./build.sh -i` command installs the two modules in your site-specific directory
for Python modules (e.g. '/usr/lib/python3/dist-packages/' on Linux).

To use py3exiv2 in your scripts, simply import the pyexiv2 module.

Note: the lib name is py3exiv2 but, for compatibility, the top-level module 
      is named pyexiv2


Documentation
=============

You can find the API documentation at: 
    http://python3-exiv2.readthedocs.org/en/latest
or refer to the internal documentation for a guide on how to use py3exiv2.
In a python interpreter, type:

 >>> import pyexiv2
 >>> help(pyexiv2)

py3exiv2's Issues

Compile hangs on Raspberry pi with 512 mb memory including 1024 swap space

I use pyexiv2 in my pi-timolo project that runs under python 2 or 3. There is a pip install for python2 but for python3, I have written a bash script to automate install of dependencies, git clone, configure, compile, install your project. This works fine on RPI's with 1 GB memory and there are no problems other than taking a bit of time to compile.

A user on a RPI zero with 512 memory complained that compile would hang. I tested and even with 1024 mb of swap the compile consumes all memory and hangs. Also swap memory is very slow since RPI OS is run on SD card.
Are there any ways to reduce the amount of memory required to compile so it can compile with 512 of RAM memory?
Thanks Claude ...

Install errors out per below. Also see log at bottom. I have checked setuptools and that appears OK

Any help would be appreciated

edit metadata from buffer

I try to edit meta data from buffer
meta = pyexiv2.ImageMetadata.from_buffer
meta.read()
meta['Exif.Photo.UserComment'] = 'abc'
meta.write()

The question is how can I retrieve the file buffer without saving to disk? thanks
