Description

While Bio-Formats is capable of reading and writing 16-bit images with more than 3 merged channels, many other TIFF readers are unable to open these images. The TIFF writer should check to see if there are more than 3 channels; if so, the channels should be split before being saved.

  • Summary changed from Don't write 16-bit TIFFs with more than 3 merged channels to Split channels on export if there are 2 or >=4 16-bit RGB channels

16-bit images with 2 RGB channels are also not handled by many TIFF readers, so the TIFF writer should split the channels if 16-bit images with 2 RGB channels are encountered.

Note that you can still save 16-bit data with any number of channels. The only thing that would change is the number of channels per image (1 or 3 instead of 1, 2, 3 or 4).
