--- Comment #3 from John <[email protected]> ---
I don't think this is a colorspace issue. For a quick test, I used imagemagick
to generate ten TIFF files with the various compression options via this
command:

> for i in None BZip Fax Group4 JPEG JPEG2000 Lossless LZW RLE Zip; do magick 
> rose: -format tiff -resize 300% -compress $i rose_"$i".tiff; done

The resultant files had the following colorspaces:


rose_BZip.tiff sRGB
rose_Fax.tiff Gray
rose_Group4.tiff Gray
rose_JPEG2000.tiff sRGB
rose_Lossless.tiff sRGB
rose_RLE.tiff sRGB
rose_JPEG.tiff sRGB
rose_LZW.tiff sRGB
rose_None.tiff sRGB
rose_Zip.tiff sRGB


All but the zip and jpeg versions were able to be imported into a LibreOffice
document. Those two gave the "Unknown image format" error. If I convert them to
YCbCr or CMYK colorspace, they still don't open, but an uncompressed version in
that colorspace will.
