Compressed multi page tiff

[wvanoeveren]

Hello,

I'm currently quite new to python but i'm finding my way pretty good and love the language more & more each day :)
but ... :) , i have currently an issue/problem where i can't find a decent solution for. I'm searching for a method to create a multipage tiff file from single page tiffs (which i found using PIL and the append_images method and which works fine) but the problem is that after creating that multipage tiff file the file size is drastically big (even too big tbh) that i would like to understand where this is coming from since the single images on themselves are quite small. The tiff single images have a jpeg compression and (as far as i can see using Preview on a mac) the multipage tiff also has this compression. I tried several methods (from the append_images/PIL method using their compression="jpeg" thing to using a conversion to a numpy array, ...) but nothing comes close to the actual result. Before i used python i've been using a toolkit called GDPicture and there the creation of the multipage tiff file (from the same source material) is going correct in terms of file size. But i need to have it in python so i'm desperately looking to find the solution :) I would like to add some of the single page tiffs but it is not allowed to attach them (so if you want/need them just give a shout on how i can deliver them).

Any help is much appreciated !
Thanks !

I have not used the package below that I am recommending you take a look at, so can't say for sure it will be of help, but it has a method named tifftools.split which at least sounds promising, so worth your checking out:

package:
pypi: https://pypi.org/project/tifftools/
GitHub: https://github.com/DigitalSlideArchive/tifftools

I don't know the answer, but if imagemagick can do it, one of the python wrappers such as wand should be able to do it as well.
