Trouble passing -co arguments

[claytonrothschild]

Great library, thank you.

When I pass co arguments on linux and mac, Pyvips fails. Mac and linux.

Any tips greatly appreciated.

kubi -r lbb -f nx px py ny nz pz test.jpg test_out.jpg -co overlap=0

Havn't looked into this but maybe it helps to move the -co before the input and output?!

Oh wait, I think it clearly says what the problem is; those options are not available when you save the output as jpeg. compression is available for Tiffs for example (you can use JPEG compression in a Tiff or LZW, DEFLATE, etc.; FYI: https://libvips.github.io/pyvips/enums.html#pyvips.enums.ForeignTiffCompression). The overlap option is only available for deepzoom (.dz) image pyramids. So I would say the errors are correct.

Here is a list of the options for jpegsave (Parameters): https://libvips.github.io/pyvips/vimage.html#pyvips.Image.jpegsave Maybe you wanted "Q" for quality (-co Q=75)? The options you are using are from https://libvips.github.io/pyvips/vimage.html#pyvips.Image.dzsave

@claytonrothschild Were you able to solve the problems and generate the desired output with kubi? Should I close this?

[claytonrothschild]

The solution is that indeed the -co arguments fail if one is not generating an image pyramid (dzsave) - as those arguments are specific to image pyramid.

Details here

So for example, this will fail:

kubi -r lbb -f nx px py ny nz pz test.jpg test_out.jpg -co overlap=0

but this will succeed no problem:

kubi -r lbb -f nx px py ny nz pz test.jpg test_out.dz -co overlap=0

We can close this!
