Handwriting editing method and system based on touch operation

Abstract

The invention relates to a handwriting editing method based on touch operation. The method comprises the steps that an editing instruction is received; position coordinates of a moving track of a touch point are obtained; boundary position coordinates of characters are obtained, whether the position coordinates of the moving track of the touch point are included in the boundary range of the characters or not is judged according to the boundary position coordinates, and the characters are selected if the position coordinates of the moving track of the touch point are included in the boundary range of the characters; the selected characters are edited in correspondence to the editing instruction. Editing operation corresponding to the editing instruction is directly carried out on the selected characters through the editing instruction obtained in advance, the problem of frequent switching of selecting and editing operation of the characters is solved, the characters can be modified in real time according to the position change of the moving track of the touch point, and the efficiency is greatly improved when multiple discontinuous characters are edited.

Description

technical field [0001] The invention relates to the technical field of handwriting editing, in particular to a handwriting editing method based on touch operation, and a handwriting editing system based on touch operation. Background technique [0002] In daily life, study, and work, when people edit handwriting on touch-based devices, they usually need to use a cursor to select handwriting, and then perform corresponding editing operations on the selected handwriting. For example, when changing the color of the handwriting, you first need to use the cursor to select part of the handwriting, and then call up the color selector to select a color to achieve the purpose of changing the color of the handwriting. [0003] For devices based on touch operation, this mode of selecting handwriting first and then editing operation brings a lot of inconvenience to the user's operation, especially in the teaching or meeting scene, when multiple discontinuous When handwriting is highlig...
