Incorrect byte in index file (index records)

[Joxit]

Oh, I found something else, I did the same for the .shp, in the spec from ESRI page 9/34 they said that record numbers begin at 1.
With hexyl, shapefile-rs begin at 0 and not 1 (check the line 00000060).

hexyl  test.shp

Hey, thank you for taking the time to report an error.

There was indeed 2 problems:

• The shape began from 0
• The shape offset written in the index file was not in '16 bit words' length

With the code from #7 the file written by your test can actually be shown by QGIS

Thank you for your fast response and fix ! 😄

Yes ! The PR fix my issue ! 🎉
