An electronic signature positioning method in a web page PDF,

Abstract

The invention discloses an electronic signature positioning method in a web page PDF, which is characterized in that the method comprises the following steps of 1) analyzing the metadata of a PDF document and recording coordinates of a position where the PDF document is located; 2) when that mouse is press, obtaining the position of the current mouse; after the mouse is moved, obtaining the position of the mouse; 3) the position calculated when the picture is clicked referring to the position of the mouse in the picture, that is, the abscissa and ordinate values of the mouse being relative tothe upper left corner of the parent level of the picture; 4) calculating the abscissa of the position before the movement, the abscissa of the ordinate and the position after the movement, and the difference between the abscissa and the ordinate; 5) replacing the abscissa and ordinate of the original element with the new abscissa and ordinate, and dragging the seal to PDF. The invention solves thetechnical problem of stamping a plurality of seals in an electronic document at one time by combining the digital signature technology, greatly improves the stamping efficiency, and adds a designatedstamp at all positions needing to be stamped.

Description
