Hi,
Thank you for this library. I have an issue in android, where the scenario is this: I have two tablets of the same resolution, where by i scroll the pdf on one tablet and using this

xx = m_view.vGetX();
yy= m_view.vGetY();

i get the x and y coordinates, when i use the following on the second tablet in code:

PDFPos pos = m_view.vGetPos(Integer.parseInt(left),Integer.parseInt(top));
m_view.vSetPos(pos,  Integer.parseInt(left), Integer.parseInt(top));

I do not seem to scroll the pdf programmatically

. could any one please assist on how to scroll the pdf. and what actual values to use in order to scroll it programmatically.
Please assist.
Thanking you

Something like this: public void vScrollPDF(int newX, int newY){ if(m_scroller != null){ m_scroller.setFinalX(newX); m_scroller.setFinalY(newY); m_scroller.computeScrollOffset(); } } and call it in your PDFReader class where you want and with the values you want: m_view.vScrollPDF(0, 1000);
