Abstract
The present invention discloses a method for adsorbing a straight line/line segment in an image, including: presetting a straight line/line segment, dragging the straight line/line segment by selecting a first part of the line segment, and when a second part of the straight line/line segment is dragged to the vicinity of a line segment in an image, setting the preset line segment to be superposed with the line segment, the vicinity referring to that a minimum distance between the second part of the straight line/line segment and the line segment meets a preset rule. In the present invention, by means of the foregoing technical solution, a user can be conveniently assisted, according to a line segment that exists in an image, to define a polygon frame, so that subsequent image processing can be conveniently performed.
