Read and write native DaVis images and vectors filetypes VC7 and IM7
ReadIM is a c++ wrapper to load DaVis Images and Vectors DaVis V8. ReadIM is a 'low level' interface to C++ libraries provided by LaVision GMBH.
The libraries have been compiled successfully on Windows platforms with 64-bit and 32-bit python. Successfully installed with latest 32 and 64 bit versions of WinPython including:
2.7, 3.3 and 3.4 Do either:
>>> pip install ReadIM
If this fails you will need to compile yourself. Clone the source and run the following.
>>> python setup.py build install
>>> python setup.py test
If the test passes then all should be okay.
To load a .vc7 file run:
>>> vbuff, vatts = ReadIM.extra.get_Buffer_andAttributeList('filename.vc7')
>>> v_array, vbuff = ReadIM.extra.buffer_as_array(vbuff)
similarly for a .im7 file run:
>>> vbuff, vatts = ReadIM.extra.get_Buffer_andAttributeList('filename.im7')
>>> v_array, vbuff = ReadIM.extra.buffer_as_array(vbuff)
>>> atts = ReadIM.load_AttributeList({'attribute':'value'})
>>> ReadIM.WriteIM7('saved_file.im7', True, buff, atts.next)
Finally, memory cleanup is not automatic. To prevent memory leaks do the following:
>>> del(vbuff)
>>> ReadIM.DestroyBuffer(buff)
>>> ReadIM.DestroyAttributeListSafe(atts)
For higher level access to DaVis files the IM package is available at: https://bitbucket.org/fleming79/im
