Reason I am asking it , I used tesserract ocr offline successfuly but when the charachters are small with the webview's screenshot i am having problem. I tried manually zooming the screenshot and worked well. So I need to zoom to webview1 before taking the screenshot for the ocr process.

Ex: Set the zoom level at Txtzoom field (see JavaFX Webview docs)

B4X:

Dim jo As JavaObject=WebView1
Dim num As Double=Txtzoom.Text
jo.RunMethod("setZoom",Array(num))

B4X:

Sub SetZoom(wv As WebView, Factor As Double)
 Dim jo As JavaObject = wv
 jo.RunMethod("setZoom", Array (Factor))
End Sub

It will be added to jFX library in the next update.

Default value is 1.

by the way is it possible to drag the view inside the webview ? Because when i zoom it it zoom to center of the webview and i cant see the right side of the view.
