FabIO Package¶

`fabio` Package¶

FabIO module

fabio.open(filename, frame=None)¶

Open an image.

It returns a FabioImage-class instance which can be used as a context manager to close the file at the termination.

with fabio.open("image.edf") as i:
    print(i.nframes)
    print(i.data)

Parameters:	filename (Union[str,FilenameObject]) – A filename or a filename iterator. frame (Union[int,None]) – A specific frame inside this file.
Return type:	FabioImage

fabio.open_series(filenames=None, first_filename=None, single_frame=None, fixed_frames=None, fixed_frame_number=None)¶

Create an object to iterate frames through a file series.

This function is a wrapper over FileSeries to facilitate simple uses of file series iterations.

Parameters:

filenames (Union[Generator,Iterator,List]) – Ordered list of filenames to process as a file series. It also can be a generator, and iterator, or filename_series or file_series objects.
first_filename (str) – If provided iterate filenames from this filename and try to consecutivelly open next files. If this argument is specified the filenames have to unspecified. Internally it uses filename_series to iterate the filenames.
single_frame (Union[Bool,None]) – If True, all files are supposed to contain only one frame.
fixed_frames (Union[Bool,None]) – If True, all files are supposed to contain the same amount of frames (this fixed amount will be reached from the first file of the serie).
fixed_frame_number (Union[Integer,None]) – If set, all files are supposed to contain the same amount of frames (sepecified by this argument)

Return type:

FileSeries

fabio.register(codec_class)¶

Register a codec class with the set of formats supported by fabio.

It is a transitional function to prepare the next comming version of fabio.

On the current fabio library, when a module is imported, all the formats

inheriting FabioImage are automatically registred. And this function is doing nothing.
On the next fabio library. Importing a module containing classes

inheriting FabioImage will not be registered. And this function will register the class.

The following source code will then provide the same behaviour on both fabio versions, and it is recommended to use it.

@fabio.register
class MyCodec(fabio.fabioimage.FabioImage):
    pass

fabio.benchmarks()¶: Run the benchmarks

fabio.tests()¶

Run the FabIO test suite.

If the test-images are not already installed (via the debian package for example), they need to be downloaded from sourceforge.net, which make take a while. Ensure your network connection is operational and your proxy settings are correct, for example:

export http_proxy=http://proxy.site.com:3128

class fabio.fabioutils.DebugSemaphore(*arg, **kwarg)¶

Bases: threading.Semaphore

threading.Semaphore like class with helper for fighting dead-locks

acquire(*arg, **kwarg)¶

Acquire a semaphore, decrementing the internal counter by one.

When invoked without arguments: if the internal counter is larger than zero on entry, decrement it by one and return immediately. If it is zero on entry, block, waiting until some other thread has called release() to make it larger than zero. This is done with proper interlocking so that if multiple acquire() calls are blocked, release() will wake exactly one of them up. The implementation may pick one at random, so the order in which blocked threads are awakened should not be relied on. There is no return value in this case.

When invoked with blocking set to true, do the same thing as when called without arguments, and return true.

When invoked with blocking set to false, do not block. If a call without an argument would block, return false immediately; otherwise, do the same thing as when called without arguments, and return true.

When invoked with a timeout other than None, it will block for at most timeout seconds. If acquire does not complete successfully in that interval, return false. Return true otherwise.

blocked = []¶

release(*arg, **kwarg)¶

Release a semaphore, incrementing the internal counter by one.

When the counter is zero on entry and another thread is waiting for it to become larger than zero again, wake up that thread.

class fabio.file_series.FileSeries(filenames, single_frame=None, fixed_frames=None, fixed_frame_number=None)¶

Bases: fabio.fabioimage.FabioImage

Provide a FabioImage abstracting a file series.

This abstraction provide the set of the filenames as the container of frames.

# Sequencial access through all the frames
with FileSeries(filenames) as serie:
    for frame in serie.frames():
        frame.data
        frame.header
        frame.index                    # index inside the file series
        frame.file_index               # index inside the file (edf, tif)
        frame.file_container.filename  # name of the source file

# Random access to frames
with FileSeries(filenames) as serie:
    frame = serie.get_frame(200)
    frame = serie.get_frame(201)
    frame = serie.get_frame(10)
    frame = serie.get_frame(2)

Files of the series can be set using a list of filenames, an iterator or a generator. It also supports a file series described using filename_series or file_series objects.

# Iterate known files
filenames = ["foo.edf", "bar.tif"]
serie = FileSeries(filenames=filenames)

# Iterate all images from foobar_0001.edf to 0003
filenames = numbered_file_series("foobar_", 1, 3, ".edf", digits=4)
serie = FileSeries(filenames=filenames)

# Iterate all images from foobar_0000.edf to the last consecutive number found
filenames = filename_series("foobar_0000.edf")
serie = FileSeries(filenames=filenames)

Options are provided to optimize a non-sequencial access by providing the amount of frames stored per files. This options (single_frame, fixed_frames and fixed_frame_number) can be used if we know an a priori on the way frames are stored in the files (the exact same amount of frames par file).

# Each files contains a single frame
serie = FileSeries(filenames=filenames, single_frame=True)

# Each files contains a fixed amout of frames.  This value is
# automatically found
serie = FileSeries(filenames=filenames, fixed_frames=True)

# Each files contains 100 frames (the last one could contain less)
serie = FileSeries(filenames=filenames, fixed_frame_number=100)

`fabio.numpyimage` Module¶

Generic numpy file reader for FabIO

class fabio.numpyimage.NumpyImage(data=None, header=None)¶

Bases: fabio.fabioimage.FabioImage

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.

Written using information gleaned from the ReadRAXISImage program written by T. L. Hendrixson, made available by Rigaku Americas. Available at: http://www.rigaku.com/downloads/software/readimage.html

class fabio.raxisimage.RaxisImage(*arg, **kwargs)¶

Bases: fabio.fabioimage.FabioImage

FabIO image class to read Rigaku RAXIS image files. Write functions are not planned as there are plenty of more suitable file formats available for storing detector data. In particular, the MSB used in Rigaku files is used in an uncommon way: it is used as a multiply-by flag rather than a normal image value bit. While it is said to multiply by the value specified in the header, there is at least one case where this is found not to hold, so YMMV and be careful.
