Using the pdfium library for pdf rendering

[petrovichtim]

Please tell me how you can rewrite this library for use with a pdfium-based renderer ?

pdfium is a C++ lib so you would need JNI to call it from java/kotlin. We have not looked at that in great detail so there might be code you can use from AOSP or existing libraries.

Just out of curiosity - why do you want to do this in the first place? Pdfium is available on all devices running at least Android 5, thats currently 94.1 % of all android devices (according to google).

We need to make the functionality of text selection and click on links to a section inside the document or to websites

ok unfortunately this is out of scope of this library - it just renders an image of the pdf (with zoom/memory optimization).
The Android built in Pdfium java wrapper used in this lib can only render images so yeah you would need your own pdfium build. If you want a drop in solution maybe have a look at pspdfkit.
