geotiff.js is a small library to parse TIFF files for visualization or analysis. It is written in pure JavaScript, and is usable in both the browser and node.js applications.
and allows geotiff to handle a situation where there is an interleaved tiff that has SampleFormat of [1], despite there being multiple samples per channel.
The situation described in the issue is that BitsPerSample is [8, 8, 8], yet SampleFormat is only [1], whereas it should have the same number of values (i.e. [1, 1, 1]). Rather than fail in this situation, be more forgiving of the incorrect format and try to infer from the value that was set.
This was noticed in some OME-TIFF files generated by qupath with Creator="OME Bio-Formats 6.11.1" in the OME-XML. These files can be opened by qupath, FIJI, and Python's tifffie, so it only makes sense that geotiff.js should handle them as well, despite the incorrect SampleFormat length.
