I've added lossless conversion to ptiff here: https://github.com/IIIF/htj2k/blob/add_vips/convert/lossless/tiff_to_ptiff.sh (assuming lossless is the same as no compression)
I've also change the compression to jpeg for the lossy pyramid tiff.
Well, technically no compression is indeed lossless ;-)
But I suggest we also use something like Deflate to allow us to have a full equivalent comparison of file size and decoding speed with respect to lossless HTJ2K:
--predictor deflate
It looks like VIPS only supports the following:
predictor - Compression prediction, input VipsForeignTiffPredictor
default: horizontal
allowed: none, horizontal, float
but it does support:
--compression deflate
Sorry, I meant to write:
--compression deflate
Great added to the vips script.
Add loss less and use jpeg for lossy.
