pdf zoom quality

[valflrt]

First, thank you so much for this app !!

It's not really priority but I noticed that the rendering quality of pdf files doesn't adjust with respect to zoom level.

For exemple the google drive pdf viewer seems to "re-render" when zooming in.

Example in pictures (first is google drive):

Thank you again and don't bother improving this if too complicated !

I'm glad you like the app!

I tried not to use a third-party libraries for PDF file preview, mainly because of the large size of these libraries (at least the best ones). Unfortunately that comes with many limitations as Android's native PDF renderer is so basic.

The current implementation of PDF (and other media viewers) is simple, and I didn't really put much effort on it, as I was focusing on other things related to the file browsing experience. Improving those (and adding more supported file extensions) will be my next goal.

Fixing the zoom quality is something I can do with the current implementation, but other basic features such as text selection is almost infeasible using the native APIs. But I'll see what I can do.
