Gallery Preview Compression

[davvok]

Hello,

i've used owncloud before and it seems to be having the same issue i've come across with nextcloud multiple times. I've probably read all the major threads about changing the compression quality and what not. None of these config.php or legacy/image.php settings seem to do the trick for me. I've tried changing jpeg and png quality to 100 but nothing has changed with the previews.

I have a bunch of large files, both in pixel size and in file size. 3MB and upwards to 12MB. and pixel sizes of 4000 to 12000. I NEED to be able to view the entire files within nextcloud. These are big images with text on them. Right now not a single letter can be read on these files. It is very unpractical for users to have all of these files downloaded within their browser and having to open them locally.

If possible, i just would really like a very simple way of changing the preview file to the source file. I and probably a bunch of other people would be really happy to have this option. Right now the preview generator actually created a bigger (from 3MB to 12MB) png file than the original one, while still managing to be blurrier than the source. This might have been the preview-generators fault, but either way, if i have a 3mb file, i'd really rather not have a 20MB preview folder of that one file. I'm completely fine with the thumbail generator and the preview that exists when clicking on the details of a file. Those a great previews. But if click to view the entire pic, i'd actually like the entire pic, not a compressed version.

Is there ANY simple way for me to do this?

Moving to using previews will fix this issue. Use the files grid view in the meantime :)
