Hi,
I have a question related to read a binary vtk file. This file has been created
using Matlab by
the command "fread". However, this file must be processed further within Python.
It is not
known to me which codec is used to encode this file. It starts with the
following characters:
/1XùB4zBÑX•Cò¼ôA4zBÑX•C~BùB4zBÑ{–CnùB4zBJž—C •øB4zB·¿˜CÃ/
//
Has anyone an idea how to decode this in normal Python strings even if it is not
known
which character set must be used? Thanks in advance.
If it is a binary file and not text, it's nearly certain that you do not use
character sets or codecs at all. Those bytes do not represent text characters in
any encoding. You will have to look at your existing Matlab code to determine
how it is interpreting those bytes. Probably, they are just floating point
numbers, either single precision or double precision. You will probably want to
use numpy to read the file once you have discovered its format.
