Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0022] The invention discloses a method for realizing original handwriting. The method includes: collecting track points in the handwriting process in real time; fitting the handwriting track according to the collected track points; Finally, the pen width value at each trajectory point is determined; finally, the fitting curve is segmented according to these pen width values ​​and then filled with a brush to complete the rendering of the original handwriting. The invention can fit the trajectory p...

Abstract

The invention discloses a handwriting original handwriting realization method. The method comprises the steps that 1 track points in a handwriting process are acquired in real time; 2 according to the acquired track points, handwriting track fitting is carried out; 3 according to the pressure value of each track point, the pen width value of each track point is determined after stroke processing; and 4 brush filling is carried out on a curve acquired through fitting in the second step according to the pen width value, which is acquired in the third step, of each track point, so as to complete original handwriting rendering. According to the invention, almost completely smooth fitting can be carried out on the track points, and original handwriting rendering can be efficiently carried out.

Description

technical field [0001] The invention relates to a method for realizing handwriting. Background technique [0002] In today's tide of information construction, electronic documents, as the most important carrier of information exchange, have received widespread attention. Both military and political departments and commercial organizations are using the network to transmit documents to maintain rapid and timely communication. Fully digital paperless office has become inevitable. How to fully digitize important links such as approval and decision-making in the writing process without being tampered with, and transfer and archive them in a common document format has become an urgent problem to be solved. Nowadays, handwriting input boards and touch screens provide a hardware basis for solving the limitations of keyboard input. Handwriting input can meet the randomness of users' handwriting. It displays the target text according to the trajectory generated by the user's swipe o...
