[Paraview] RE : vtk ascii to binary

[BOUSSOIR Jonathan 167706]

Hi,

Sorry to introduce me in this conversation but it's very interesting for me.
I have a little query about the functions reader VTK.
Can I use a mmap to import the data file ?
Like this code 

import mmap
import os
import time
from paraview.simple import *

filename = "sphere.vtk"

file = open(filename, "r+")
size = os.path.getsize(filename)
data = mmap.mmap(file.fileno(), size, flags=mmap.MAP_SHARED, prot=mmap.PROT_READ)   #Linux

r = LegacyVTKReader()
???
But after, I don't see how I can do...


Thanks in advance for your kind help.

Regards, 
Jona

With ParaView 3.6, you can do:

from paraview.simple import *
r = LegacyVTKReader()
r.FileNames = ["foo.vtk"]
w = servermanager.writers.DataSetWriter()
w.Input = r
w.FileName = "bar.vtk"
w.UpdatePipeline()

You will have to create a loop where you do the following 3:

for index in range...:
  r.FileNames = ["foo%d.vtk"  % index]
  w.FileName = "bar%d.vtk % index
  w.UpdatePipeline

To convert binary to ascii, do
w.FileType = 'Ascii'
