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
