ReadIM 0.8.2

Read and write native DaVis images and vectors filetypes VC7 and IM7

Overview

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.

Installation

This module is compiled. If there isn’t a binary you’ll need to have the appropriate build tools installed.

>>> 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.

Usage

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)

Writing files

>>> 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)
