Tiff to JPEG 2K error

[Stephen Yip]

Dear community,

I am trying to convert our WSI from TIFF to JPEG 2K using libtiff.h of
OpenSlide.

However, I keep getting this following error.
TIFFReadRawTile: Read error at row 4294967295, col 4294967295; got
18446744073709551615 bytes, expected 0.

........
I suspected that this is due to the data loss on our WSI (see attached for
snapshot; where red arrow highlighted patch w/ data loss).

1. Does anyone know how to repair this data loss?
2. Since the blurry patches are only small % of our WSIs, I wonder if there
is any way to override the error and still get the conversion done.

Thank you very much!
Stephen
