I'm developing an android application using PDF SDK while I need to zoom to a specific text column. E.g. in a two column page, if you double tap on a column, the reader should zoom to fit that column. How this is possible with PDF SDK?
Thanks in advance.
this is the zoom's standard behaviour.
If you want to increase the zoom you have to modify the zoomLevel in default_config() void in Global class (max 5).
With this m_view.vGetScale(); you can get the current scale.
With this m_view.vGetMaxScale(); you can get the max scale.
With this m_view.vGetMinScale(); you can get the min scale.
This is default action of double tap to increase zoom level. My point is how to find the proper zoom scale to be passed to vSetScale, based on the content width of the position where the user has touched the screen.
