Please clarify DataArray byte array format requirements for .vtu files
Hi,
I'm trying to target .vtu output for a meshing tool, and when implementing the official file format specification here:
https://examples.vtk.org/site/VTKFileFormats/#unstructuredgrid
there seem to be important aspects of the formatting that are never mentioned. The byte arrays in tags are apparently supposed to have a header that encodes the number of (unencoded) bytes in the array (which is surprising, because base64 encodings need no such header). I only figured this out after several hours of debugging and eventually finding a helpful unofficial document about the format here: https://www.earthmodels.org/software/vtk-and-paraview/vtk-file-formats
Can https://examples.vtk.org/site/VTKFileFormats/ please be updated to better reflect the file format requirements (specifically, byte array header requirements for compressed/uncompressed data)? At present, this official page is the top search result, so it's important to completely document the file format requirements!
Thank you,
Sam
