BigTIFF support ?

[geektortoise]

Version Information:

• TIFF Java Version: 2.0.0
• Java Version: (java -version) : openjdk version "1.8.0_181"
• Platform & OS: Debian

Expected Results:

• What did you expect to happen? Can use the librairy to get metadata of a bigTIFF

Observed Results:

• What happened instead?
  mil.nga.tiff.util.TiffException: Invalid file identifier, not a TIFF

• How often does this occur? Every time

Output:

• Any logs, errors, or output messages?
  mil.nga.tiff.util.TiffException: Invalid file identifier, not a TIFF

Steps to Reproduce:

1. TIFFImage tiffImage = TiffReader.readTiff(new File("/tmp/test.tif"));
   where test.tif is a bigtiff (so the
   https://github.com/ngageoint/tiff-java/blob/master/src/main/java/mil/nga/tiff/util/TiffConstants.java#L23
   FILE IDENTIFIER is 43)

Test Files:

• Links to any files needed for testing? you can convert a jpeg to bigtiff with libvips
  /usr/local/bin/vips tiffsave "test.jpeg" "test.tif" --tile --pyramid --bigtiff

I know that it is not possible for java to handle a huge file > 2Gb or 4 Gb. But is it planned to be able to read and modify metadata of bigtiff ?

Nothing currently planned, but not opposed to supporting and open to pull requests.

Did you found another way to open BigTiff?
