Dear libtiff-Developers,

Because we need some validation and repair tools for TIFFs by reasons of digital preservation, we developed

To ensure that we does not have (a lot of) bugs included, we invite you to test both tools and verify stability of checkit_tiff against your TIFF collection.

Additional I have a question about the flag "rm"/"rM" of the TIFFOpen() function. I am right, that the "rM" uses memmapped I/O? But with my tests, it does not differ in speed with "rm"-mode. Could you explain, how it works in detail?

Thanks in advance.

Mit freundlichen Grüßen
With best regards,

Andreas Romeyke
