Maybe we could just make another pyvips package (`pyvips-system`?) without a dependency on `pyvips-binary`?
Hooray! This is really great Kleis.
Shall we do 3.0.0? I think everything is ready now.
Congratulations! ... I'm being dumb, I don't seem to be able to get pyvips to find its libvips on ubuntu: ``` $ pip install pyvips-binary==8.16.0 ... Downloading pyvips_binary-8.16.0-cp37-abi3-manylinux_2_28_x86_64.whl (7.2 MB)...
Hello @afriebel85, How many files are you stitching together? Windows has a hard limit of 2000 (I think). You might need to find a linux machine (or use WSL) if...
Is this colour deconvolution, or something fancier? If it's just colour deconv, you can do that directly in pyvips and avoid a *lot* of processing. If your tiles are in...
Yes, that sounds like colour deconvolution. There's some sample pyvips code here: https://github.com/libvips/pyvips/issues/289#issuecomment-994539912 You just need to generalise to more than three channels, it should be easy. Maybe for another...
Hello @mcosti, Like most systems, libvips automatically disables chroma subsample if Q >= 90. Try: ``` $ vips copy sample.jpg x.jpg[subsample-mode=on,Q=100] $ ls -l sample.jpg x.jpg -rw-rw-r-- 1 john john...
Camera JPG encoders will often produce images with slightly different file sizes. The Q factor is not a standardised feature and you can't compare it between different jpeg encoder libraries.
Hello @kuldeep203, This is a difficult problem, and how much work you need to do depends on how accurate your translation stage is, the level of pixel access you have...
