I need to scroll to Page number 10 PDFPos x= 204.57294 PDFPos y =453.0561 PDFPos vx = -171 PDFPos vy -323

I tried to achieve by following :

PDFPos pos = m_view.vGetPos((int)204.57294, (int)453.0561);
m_view.vSetPos(pos, -171, -323);
invalidate();

But it doesnt work. Please direct me how to achieve this.

Hi,

Its not working, doesnt move page to specified location.

I need to scroll pdf to fixed x,y and vx,vy when opened.

My Queries:
1. Does vSetPos sets pdf view part to specified position.
2. In vSetPos how to set x,y,vx,vy 4 values.

Its urgent any direction is appriciated.

Thanks.

public class PDFPos
{
public int pageno;//pageno to be jump
public float x;//x in PDF coordinate
public float y;//y in PDF coordinate
};

vx, vy: PDFPos shall be at the point of screen, and this may adjust by max width and max height of Document.


vSetPos works after first PDFView.vResize() called.
and width, height can't be 0 for PDFView.vResize().

Hi,

As you suggested i have put resize and it changes the page to random place as i set vresize(100,100)
but then values of vSetPos doesnt changes to x,y specified.

Can u share any working code demo.

Also need to confirm vSetPos shows parameter vx,vy [vSetPos(PDFPos pos, int vx, int vy)
)] according to document but we are passing x,y. However i tried both but pdf doesnt move to show as attached image.

Thanks.

PDFReader.onSizeChanged()
has some codes, to record position at screen (w/2,h2) (center of the View)
and after screen changed, put the position back to screen (w/2,h2)

if you want jump to a page, and show [top-left of page] at [top-left of screen].
codes like:
