Allow the thumbnail to be stretched to fit

[oregonpillow]

At the moment, my newspapers look like this in Komga:

which looks less nice than the same view you would get using Inkheart (https://gitlab.com/Nystik/inkheart):

I'm not trying to make this a competition between projects, but i think we can agree that stretching the pdf covers to fill the entire thumbnail space looks objectively nicer in this example.

Would it be possible to implement something like this? So that the user has the ability to select "stretch to fit" or equivalent?

The 2 screenshots don't show the same books, this is not a very good comparison.

@gotson Here's a better 1:1 comparison, sorry:

Komka seems to zoom out to fit the first page in thumbnail (no matter the aspect ratio) whereas Inkheart in comparison, seems to do the opposite; extract the first page to match the aspect ratio of thumbnail layout

thanks for the new screenshots, it's clearer that way. Komga fits the whole thumbnail by design, because for comics it doesn't look good to crop. I notice that Inkheart manages to crop the bottom only, which is nice.

@oregonpillow would you be able to share 1 of those newspaper files with me (i really only need the cover), so i can test things ?

[oregonpillow]

@gotson here is just the front page of one: ex1.pdf

I'm doing some tests, for reference this is the current behaviour:

Here is what i managed to accomplish:

Does that look alright to you ?

I still have to figure out a way to expose/configure/store that setting though.

I think that looks great, it fills the frame well :) thanks for giving this a go!
