Installation
============
FabIO can, as any Python module, be installed from its sources,
-available on sourceforge but we advice to use binary
-packages provided for the most common platforms on sourceforge:
-Windows, MacOSX and Linux. Moreover FabIO is part of the common
-Linux distributions Ubuntu (since 11.10) and Debian7 where the

+Since Python 2.7.10 and 3.4, PIP is installed together with Python itself.

+and executed using your standard Python:

- pip install fabio

Installation from sources
.........................
-Install the required dependencies (via PIP or a repository), then retrieve the Microsoft compiler and install it from:
-http://aka.ms/vcpython27
+Get the compiler
+^^^^^^^^^^^^^^^^
+Install the required dependencies, then retrieve the
+`Microsoft compiler <http://aka.ms/vcpython27>`_ and install it.
+
+**Nota**: the version of the compiler and the version of the Microsoft SDK
+have to match the Python version you are using.
+This link is for Python2.7.
+Other version of Python require differents compiler and runtime.
+
+Compile the sources
+^^^^^^^^^^^^^^^^^^^
Once done, follow the classical procedure (similar to MacOSX or Linux):
-* download sources of FabIO from fable.sourceforge.net.
+* download sources of `the latest release <https://github.com/kif/fabio/releases/latest>`_
+or `the development version <https://github.com/kif/fabio/archive/master.zip>`_.
* unzip the archive
-* run ``python setup.py build install``
+* open a cmd.exe console in the unzipped archive directory
+* run::
+ pip install setuptools wheel
+ pip install -r requirements.txt
+ python setup.py build
+ python setup.py test
+ pip install .
+
+
+Testing version of FabIO
+........................
+
+Continuous integration runs the complete test suite on multiple operating
+systems and python version.
+Under Windows, this is done using the
+`AppVeyor cloud service <https://ci.appveyor.com/project/kif/fabio>`_
+Select the environment which matches your setup like
+**Environment: PYTHON=C:\Python34-x64, PYTHON_VERSION=3.4.3, PYTHON_ARCH=64**
+and go to **artifacts** where wheels and MSI-installers are available.

Two tarball are created, one with all source code (and only source code) and the other one with all test-data.
+There is also a script which builds a bunch of *real* debian packages:
+
+* *fabio-viewer*: the GUI for visualizing diffraction images
+* *fabio-doc*: the documumentation package
+* *python3-fabio*: library built for Python3
+* *python3-fabio-dbg*: debug symbols for Python3
+* *python-fabio*: library built for Python2
+* *python-fabio-dbg*: debug symbols for Python2
+
+For this, you need a complete debian build environment:
+
+::
+
+ sudo apt-get install cython cython-dbg cython3 cython3-dbg debhelper dh-python \
+ python-all-dev python-all-dbg python-h5py \
+ python-lxml python-lxml-dbg python-matplotlib python-matplotlib-dbg python-numpy\

Test suite
----------
FabIO has a comprehensive test-suite to ensure non regression.
When you run the test for the first time, many test images will be download and converted into various compressed format like gzip and bzip2 (this takes a lot of time).
-Be sure you have an internet connection and your environment variable http_proxy is correctly set-up. For example if you are behind a firewall/proxy:
+Be sure you have an internet connection and your proxy setting are correctly defined in the environment variable *http_proxy*.
+For example if you are behind a firewall/proxy:
-::
+Under Linux and MacOSX::
export http_proxy=http://proxy.site.org:3128
+Under Windows::
+
+ set http_proxy=http://proxy.site.org:3128
+
+Where *proxy.site.org* and *3128* correspond to the proxy server and port on your network.
+At ESRF, you can get this piece of information by phoning to the hotline: 24-24.

Many tests are there to deal with malformed files, don't worry if the programs complains in warnings about "bad files",
it is done on purpose to ensure robustness in FabIO.

+Nexus -> CBF
+============
+
+In this tutorial we will see how to export a Nexus archive produced by
+the Eiger detector from Dectris into a bunch of CBF files, similar to
+the one generated by Pilatus detectors, using the FabIO library to write
+images and h5py to read them.
+
+**Nota:** HDF5 files produced by Nexus detector use a specific LZ4
+plugin for reading/writing. They require recent version of hdf5 (1.8.12
+at least).

+ FabIO image class for Images for numpy array dumps
+
+ Source: http://docs.scipy.org/doc/numpy/neps/npy-format.html
+
+Format Specification: Version 1.0
+=================================
+
+The first 6 bytes are a magic string: exactly “x93NUMPY”.
+
+The next 1 byte is an unsigned byte: the major version number of the file
+format, e.g. x01.
+
+The next 1 byte is an unsigned byte: the minor version number of the file format, e.g. x00.
+Note: the version of the file format is not tied to the version of the numpy package.
+
+The next 2 bytes form a little-endian unsigned short int: the length of the
+header data HEADER_LEN.
+
+The next HEADER_LEN bytes form the header data describing the array’s format.
+It is an ASCII string which contains a Python literal expression of a dictionary.
+It is terminated by a newline (‘n’) and padded with spaces (‘x20’) to make the
+total length of the magic string + 4 + HEADER_LEN be evenly divisible by 16 for
+alignment purposes.
+
+The dictionary contains three keys:
+
+ “descr” : dtype.descr
+ An object that can be passed as an argument to the numpy.dtype() constructor
+ to create the array’s dtype.
+ “fortran_order” : bool
+ Whether the array data is Fortran-contiguous or not.
+ Since Fortran-contiguous arrays are a common form of
+ non-C-contiguity, we allow them to be written directly
+ to disk for efficiency.
+ “shape” : tuple of int
+ The shape of the array.
+
+For repeatability and readability, this dictionary is formatted using
+pprint.pformat() so the keys are in alphabetic order.
+
+Following the header comes the array data. If the dtype contains Python objects
+(i.e. dtype.hasobject is True), then the data is a Python pickle of the array.
+Otherwise the data is the contiguous (either C- or Fortran-, depending on fortran_order)
+bytes of the array. Consumers can figure out the number of bytes by multiplying the
+number of elements given by the shape (noting that shape=() means there is 1 element)
+by dtype.itemsize.
+
+Format Specification: Version 2.0
+=================================
+
+The version 1.0 format only allowed the array header to have a total size of 65535 bytes.
+This can be exceeded by structured arrays with a large number of columns.
+The version 2.0 format extends the header size to 4 GiB.
+numpy.save will automatically save in 2.0 format if the data requires it,
+else it will always use the more compatible 1.0 format.
+
+The description of the fourth element of the header therefore has become:
+
+ The next 4 bytes form a little-endian unsigned int: the length of the header data HEADER_LEN.
