Generate thumbnails for PDF documents

[Telkir]

I'm hugely impressed with Copyparty and after a little experimentation and setup it's definitely going to become my new home fileserver. Thanks a ton for your work!

As per the title, one feature I'd really like to see is thumbnail generation for PDF documents. Not sure how feasible it would be to add but just wanted to mention it here in case it makes the cut for a future version.

You can already do this using libvips, however it's not disabled by default because it might cause segfaults (especially on musl), according to @9001 . (I tried to reproduce this, but couldn't get it to happen)

Add it to th-r-vips, e.g. --th-r-vips "avif,exr,fit,fits,fts,gif,hdr,heic,jp2,jpeg,jpg,jpx,jxl,nii,pfm,pgm,png,ppm,svg,tif,tiff,webp,pdf"

Don't forget to install pyvips.

If you do get segfaults on some of your files, help with troubleshooting would be appreciated.

I just discovered copyparty few days ago and thanks a lot for it. That's nice to see a light and efficient file manager (and more).

I have tried the option you describe here by adding in the ~/.config/copyparty/copyparty.conf configuration file, in [config] section the following line. The documentation was not clear (or too long), for me to be found. this file is the config file loaded, as the visible directory is the one I defined. I launch it with systemctl --user copyparty

th-r-vips: "avif,exr,fit,fits,fts,gif,hdr,heic,jp2,jpeg,jpg,jpx,jxl,nii,pfm,pgm,png,ppm,svg,tif,tiff,webp,pdf"

And there is still no preview for pdf. There is still and there was already before this line, preview for jpg, png and svg formats, but not for pdf. I see the conversion to webp in log the following way:

journalctl --user -xeu copyparty

I use Arch Linux ARM. where everything seems to be well packaged, and installed python-pyvips (that automatically install libvips dependency). I also have python-pillow, but I don't thing it is used for pdf. There is maybe a problem with package, arch linux arm is sometime less reliable than arch linux (x86_64 or riscv64) for packages.

You need to put it into the [global] section, i dont think [config] does anything. Also, you can drop the quotes. Here's a snippet from my own config:

[global]
  th-r-vips: pdf,avif,exr,fit,fits,fts,gif,hdr,heic,heics,heif,heifs,jp2,jpeg,jpg,jpx,jxl,nii,pfm,pgm,png,ppm,svg,tif,tiff,webp  # formats to thumbnail with vips

If ~/.config/copyparty/copyparty.conf is getting loaded (with -c) by that systemd service, then that should be all the necessary config

you said you added the line to the [config] section, however copyparty does not have such a thing, did you mean the [global] section?

if you did use [global] in your config-file then your config sounds good, and my suspicion is that libvips (which is used by pyvips) was built without support for pdf files on arch linux arm

sniped by the fastest guy in the west... 😁

Oops, sorry, that was in [global] section, and thank you very much for the very quick answer. The problem was the "" around the formats, it works now! :)
