Package: libtiff-tools Version: 4.0.2-4 Severity: important I believe there an issue with tiff2rgba, for some reason it does not seems to be able to deal with BigTIFF as should.
Eg: $ tiff2rgba -c none -n bigtiff.tif bigtiff3.tif TIFFAppendToStrip: Maximum TIFF file size exceeded. TIFFAppendToStrip: Maximum TIFF file size exceeded. TIFFAppendToStrip: Maximum TIFF file size exceeded. where: $ tiffinfo bigtiff.tif TIFF Directory at offset 0x2367dba90 (9504144016) Image Width: 78000 Image Length: 30462 Resolution: 10, 10 pixels/cm Bits/Sample: 8 Compression Scheme: None Photometric Interpretation: RGB color Extra Samples: 1<assoc-alpha> Orientation: row 0 top, col 0 lhs Samples/Pixel: 4 Rows/Strip: 16 Planar Configuration: single image plane However it should always be possible to reduce an RGBA uncompressed TIFF into RGB uncompressed TIFF. What looks suspicious is this: $ tiff2rgba -n bigtiff.tif bigtiff2.tif $ tiffdump bigtiff2.tif bigtiff2.tif: Magic: 0x4949 <little-endian> Version: 0x2a <ClassicTIFF> ... while input is: $ tiffdump bigtiff.tif bigtiff.tif: Magic: 0x4949 <little-endian> Version: 0x2b <BigTIFF> My guess is that tiff2rgba try hard to write out ClassicTIFF when BigTIFF is required. -- System Information: Debian Release: 6.0.6 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable'), (200, 'testing'), (100, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 3.2.0-0.bpo.3-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages libtiff-tools depends on: ii libc6 2.11.3-4 Embedded GNU C Library: Shared lib ii libjpeg62 6b1-1 The Independent JPEG Group's JPEG ii libtiff4 3.9.4-5+squeeze5 Tag Image File Format (TIFF) libra ii zlib1g 1:1.2.3.4.dfsg-3 compression library - runtime libtiff-tools recommends no packages.
