Format of .VTI ( VTK)

Any one know , what is the format of .vti . This type of files are used to store series of image data (structured way to store data) . By knowing the format it would be easy to implement by my own. ( Store multiple images into this file for further processing for reconstruction).

Problem is this type of files are stores data in Binary format.

Any help should be appreciated....

Do not mark it as duplicate ( Convert a jpeg image series into vti image file) this question is totally different..)

.vti, as any other format from VTK are open format. See their specification here. https://vtk.org/wp-content/uploads/2015/04/file-formats.pdf

ImageData

EachImageData piece specifies its extent within the dataset’s whole extent. The points and cells are described implicitly by the extent, origin, and spacing. Note that the origin and spacing are constant across all pieces, so they are specified as attributes of the ImageData XML element as follows.

<VTKFile type=”ImageData” ...>
  <ImageData WholeExtent=”x1 x2 y1 y2 z1 z2”
        Origin=”x0 y0 z0” Spacing=”dx dy dz”>
    <Piece Extent=”x1 x2 y1 y2 z1 z2”>
      <PointData>...</PointData>
      <CellData>...</CellData>
    </Piece>
  </ImageData>
</VTKFile>
