Hi,

you can use setRect method of PDFAnnot class.
e.g.

Code:

//get annotation instance at point
    m_annot = [page annotAtPoint:m_annot_pos.x: m_annot_pos.y];
    
    //create new rect
    PDF_RECT rect;
    rect.left = 100;
    rect.right = 300;
    rect.top = 100;
    rect.bottom = 300;
    
    //set rect of the annotation
    [m_annot setRect:&rect];
    
    // Re-render the current page
    [m_view vRenderSync:m_cur_page];
    [self refresh];
    
    // Save the PDF file
    [m_doc save];

Time to create page: 0.380 seconds
