    ClientToDocument Method
    In This Topic
    Converts a point in the current C1PreviewPane's client coordinates, to document coordinates.

    Document coordinates are also pixels, but are relative to a specific page's left top corner, and do not depend on the current zoom factor.

    For instance, a client point that is over a page's right top corner would yield a point with document coordinates (816,0) on a 96 DPI resolution display for a 8.5 in wide page (816 is 8.5 multiplied by 96), regardless of the current zoom factor or document scroll position in the preview.
