Abstract

The present application provides a handwriting erasing method and device, the method comprising: acquiring an erasing curve drawn in an erasing mode for erasing a handwriting curve, the handwriting curve being a curve drawn in a pen mode; A polygon is obtained by connecting the starting point and the end point of the curve; determining and erasing a part of the curve within the polygon from the handwriting curve. This application can realize the segmentation of any complex handwriting when performing the erasure of handwriting broken lines, and realize the one-time erasing of the handwriting located in the erasing area after segmentation, thereby simplifying the process of handwriting erasing and improving the quality of handwriting erasing. Deletion efficiency, improve user experience.

Description

technical field [0001] The present application relates to the technical field of graphics, in particular to a method and device for erasing handwriting. Background technique [0002] In the process of computer graphics processing, in order to correct wrong handwriting or process handwriting, it is usually necessary to erase some drawn handwriting. [0003] Existing handwriting erasing methods, such as erasing points on polylines, erasing polygons, erasing intersections of regular erasing areas, etc. However, when erasing broken lines of handwriting, it is impossible to segment arbitrarily complex handwriting, and it is impossible to erase multiple complex handwriting at one time, that is, the handwriting erasing process is complicated and the erasing efficiency is low, which affects user experience. Contents of the invention [0004] In view of this, the present application provides a method and device for erasing handwriting, which can simplify the process of erasing ha...
