get annotation rect codes like(in [PDFView onSingleTap])

[m_annot getRect:&m_annot_rect];
m_annot_rect.left = [vpage GetX] - self.contentOffset.x * m_scale + [vpage ToDIBX:m_annot_rect.left];
m_annot_rect.right = [vpage GetX] - self.contentOffset.x * m_scale + [vpage ToDIBX:m_annot_rect.right];
float tmp = m_annot_rect.top;
m_annot_rect.top = [vpage GetY] - self.contentOffset.y * m_scale + [vpage ToDIBY:m_annot_rect.bottom];
m_annot_rect.bottom = [vpage GetY] - self.contentOffset.y * m_scale + [vpage ToDIBY:tmp];

and draw rect like:

-(void)drawAnnot:(CGContextRef)context
{
    if( m_status == sta_annot )
    {
        int dx = m_tx - m_px;
        int dy = m_ty - m_py;
        CGContextSetLineWidth(context, 1);
        CGContextSetRGBStrokeColor(context, 0, 0, 0, 1);
        CGRect rect1 = CGRectMake(self.contentOffset.x + (m_annot_rect.left+dx)/m_scale,
                                  self.contentOffset.y + (m_annot_rect.top+dy)/m_scale,
                                  (m_annot_rect.right - m_annot_rect.left)/m_scale,
                                  (m_annot_rect.bottom - m_annot_rect.top)/m_scale);
        CGContextStrokeRect(context, rect1);
    }
}

I am using your code from your give step but this gives me wrong cordinate like this.
PDFVPage *pg =[[PDFVPage alloc] init:m_doc :2];
PDF_RECT rect;
float m_scale = [[UIScreen mainScreen] scale];
[annot getRect:&rect];
rect.left = [pg GetX] - m_view.contentOffset.x * m_scale + [pg ToDIBX:rect.left];
rect.right = [pg GetX] - m_view.contentOffset.x * m_scale + [pg ToDIBX:rect.right];
float tmp = rect.top;
rect.top = [pg GetY] - m_view.contentOffset.y * m_scale + [pg ToDIBY:rect.bottom];
rect.bottom = [pg GetY] - m_view.contentOffset.y * m_scale + [pg ToDIBY:tmp];
-2
