remove extra margins for pdfs? #1232

Open somesortofrescuetoaster opened 5 months ago

somesortofrescuetoaster commented 5 months ago

Is there a setting I'm missing to get rid of the huge extra margins that librera adds to pdfs? I hate it so much and makes the app unusable for me trying to read some pdfs. Scroll lock is not adequate as I sometimes want to pan left and right when zoomed in, but why can't it just stop scrolling at the left and right pdf margins?

I think, that are the default margins. Yes, there is an option to crop them:

You can see in the background that the margins are much smaller already.

Maybe change crop setting to your needs manually.

This should work for scroll, as well as book mode. You might need to reopen the PDF after enabling the setting.

Or did I misunderstand something?

I tried the cropping function. It doesn't do anything for the extra space that librera seems to put as a background for the pdf? Screenshot_20240121-131018 Screenshot_20240121-131033 Screenshot_20240121-131044 Screenshot_20240121-131120

Ooh. You want to have the panning stop at the edges of the real page? So the page edges mark your movement area.

I personally don't know of any option for that. Sorry, I misunderstood that.

That's what the lock in the bottom right corner is for.

If it's a double column article, the lock button is inconvenient. I want to zoom in to have a single column for the width, but then when I scroll right, it's too easy to scroll past the margins of the pdf. Or even if single column, on my small phone, I want to zoom in and scroll left and right without the app going way past the pdf margins. Probably with better finger dexterity I could make it work fine, but as of now, I find it an annoying experience on my phone compared to other pdf viewers that stop at the pdf margins.

If it's two columns, you can try turning on half-page mode together with locking.

It might help with the size, even, if it's just a little...

You could also change this issue to a feature request, probably?

It would be nice to have a "stay within page margins" feature for those who don't use the page lock (for whatever reason).
