 Are you sure this is still true with the latest tiff2rgba?  The version
 that reportbug thinks you have predates bigtiff support.

Yes. This is still present in jessie.

Bug#692460: TIFFAppendToStrip: Maximum TIFF file size exceeded

[Mathieu Malaterre]

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: 1assoc-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.
