How could i get the zoom in/out ratio when a user uses two fingers to zoom in/out a pdf file. I need a callback.

When a pdf is opened it starts with the zoom level you have set.

Im not sure if that is what you are trying to do ?

Sorry, my question was not clear. I mean how could I get zoom in ration when a user uses two fingers zoom in/out the pdf?

`pdfView = findViewById(R.id.pdfView);

pdfView.setMinZoom(1f);

pdfView.setMidZoom(2.5f);

pdfView.setMaxZoom(10.0f);`
