Hi,

checkit_tiff version 1.5.0 "deep funky funk" is now available.

checkit_tiff is a conformance checker for baseline TIFFs and is one of the 
fastest TIFF validators (1751 TIFFs in 2.75s on Core i7, 4.8Ghz)

New features:

    - With version 1.5.0, recursive scanning of directories is supported for 
the first time ("-D" option)
    - baseline IFD (IFD0) and tag-based IFDs are also checked for empty IFDs 
(tag count = 0) in "mode(enable_ifd_checks)".
    - baseline IFD (IFD0) and also tag-based IFDs are checked in 
"mode(enable_ifd_checks)" for offsets that are outside the file size


Side note: Both of the checks mentioned are not yet supported by “dpfmanager”¹.

Error images at Imagemagick results in messages:

    - "display-im6.q16: Sanity check on directory count failed, zero tag 
directories not supported. `TIFFFetchDirectory' @ error/tiff.c/TIFFErrors/603. 
display-im6.q16: Failed to read custom directory at offset 30944552. 
`TIFFReadCustomDirectory' @ error/tiff.c/TIFFErrors/603."
    - " display-im6.q16: Sanity check on directory count failed, this is 
probably not a valid IFD offset. `TIFFFetchDirectory' @ 
error/tiff.c/TIFFErrors/603. display-im6.q16: Failed to read custom directory 
at offset 30944164. `TIFFReadCustomDirectory' @ error/tiff.c/TIFFErrors/603."

Bug fixes:

    - Improvement in memory handling
    - Modernization in cmake (compile environment detection, support ninja, 
clang-tidy, etc.)

The JS variant and TAR-ball are available at 
http://andreas-romeyke.de/software.html#_checkit_tiff
The release is available in the repository at 
https://git.fsfe.org/art1pirat/checkit_tiff/releases.

I would appreciate any feedback!

Best regards Andreas
