You're right, I didn't change the offset for the compressed files. I
wrote now the offsets a posteriori with fgetpos/fsetpos and it is OK.
Thanks for your help,
Sébastien

vtkXMLUnstructuredGridReader (0xa030228): Cannot read points array
from Points in piece 0. The data array in the element may be too short.
Note that the error occurs when reading the Points array, not your
data array.
The problem is here:
<Points>
<DataArray type="Float64" NumberOfComponents="3" format="appended"
offset="16420"/>
</Points>
The offset needs to point at the offset from '_' to the beginning of the
compression header for the Points array. The offset you give is the
uncompressed size, but it should account for the compressed size of the
array before it.
Note that files written by VTK have extra whitespace after the offset
field
because they actually reserve space to seek back and set it *after*
writing
earlier arrays to the AppendedData section.
