import

>>> import py4uview

How to use?

1. use read_uv_dat() function to read the data and metadata.

In [1]: import py4uview as pu

In [2]: data = pu.read_uv_dat("./testfiles/LEEM.dat")

In [3]: data.metadata
Out[3]:
{'id': b'UKSOFT2001',
 'size': 104,
 'version': 8,
 'bitsperpix': 16,
 'width': 1024,
 'height': 1024,
 'noimg': 1,
 'attachedRecipeSize': 0,
 'isize': 288,
 ......

In [4]: data.data
Out[4]:
array([[3047, 2880, 2652, ..., 2716, 2630, 2562],
       [2789, 2848, 2862, ..., 2549, 2485, 2655],
       [2808, 2840, 2739, ..., 2640, 2602, 2747],
       ...,
       [3054, 2675, 2656, ..., 1926, 2017, 2021],
       [2885, 2949, 2705, ..., 1907, 1886, 1945],
       [2810, 2688, 2807, ..., 2009, 2025, 2641]], dtype=uint16)

2. Use Uview class method read_dat() to read the dat file

In [1]: import py4uview as pu

In [2]: data = pu.Uview.read_dat("./testfiles/LEEM.dat")

In [3]: data.attrs
Out[3]:
{'id': b'UKSOFT2001',
 'size': 104,
 'version': 8,
 'bitsperpix': 16,
 'width': 1024,
 'height': 1024,
 'noimg': 1,
 'attachedRecipeSize': 0,
 'isize': 288,
 ......

In [4]: data.data
Out[4]:
array([[3047, 2880, 2652, ..., 2716, 2630, 2562],
       [2789, 2848, 2862, ..., 2549, 2485, 2655],
       [2808, 2840, 2739, ..., 2640, 2602, 2747],
       ...,
       [3054, 2675, 2656, ..., 1926, 2017, 2021],
       [2885, 2949, 2705, ..., 1907, 1886, 1945],
       [2810, 2688, 2807, ..., 2009, 2025, 2641]], dtype=uint16)
