Function vtkio::parse_legacy_be

pub fn parse_legacy_be(reader: impl Read) -> Result<Vtk, Error>

Parse a legacy VTK file from the given reader.

If the file is in binary format, numeric types will be interpreted in big endian format. Note that this function and parse_legacy_le also work equally well for parsing VTK files in ASCII format.

Examples

Parsing an ASCII file:

use vtkio::model::*; // import model definition of a VTK file
let vtk_ascii: &[u8] = b"
# vtk DataFile Version 2.0
Triangle example
ASCII
DATASET POLYDATA
POINTS 3 float
0.0 0.0 0.0
1.0 0.0 0.0
0.0 0.0 -1.0

POLYGONS 1 4
3 0 1 2
";

let vtk = vtkio::parse_legacy_be(vtk_ascii).expect("Failed to parse vtk file");

assert_eq!(vtk, Vtk {
    version: Version::new((2,0)),
    byte_order: ByteOrder::BigEndian, // This is default
    title: String::from("Triangle example"),
    data: DataSet::inline(PolyDataPiece {
        points: vec![0.0f32, 0.0, 0.0, 1.0, 0.0, 0.0, 0.0, 0.0, -1.0].into(),
        polys: Some(VertexNumbers::Legacy {
            num_cells: 1,
            vertices: vec![3, 0, 1, 2]
        }),
        data: Attributes::new(),
        ..Default::default()
    })
});
