Problems solved by technology

[0005] The first is to connect the points passed by the stylus into a line to form handwriting input. The handwriting obtained by this processing is not smooth enough and lacks the real effect of the stylus;
[0006] The second method is realized by curve fitting, which is to calculate a smooth curve that is closest to all sampling points, and then use the curve drawing

Embodiment Construction

[0041] Aiming at the existing handwriting input system, such as the handwriting processing method adopted by the tablet computer, the strokes of the user's written characters cannot be displayed, and when the strokes are processed, the display speed of the handwriting lags behind the user's writing speed, etc. The present invention provides A new method for realizing handwritten original handwriting. The method provided by the invention does not need complex curve drawing, thereby avoiding the graphics processing of the system, and adopts a hand-crafted special handwriting drawing algorithm to directly operate the underlying graphics module to convert the handwriting It is constructed as a bitmap and delivered to the underlying graphics module for display, thereby improving the processing speed of the pen and bringing users a smooth writing experience.

[0042] The present invention will be further described in detail below through specific embodiments in conjunction with the a...

Abstract

The invention provides a method for realizing original handwriting. The method comprises the following steps of: sampling a contact in real time and acquiring the position information and practical pen width of a sampling point; obtaining the central line of a stroke between adjacent sampling points and the position information and longitudinal pen width of each point on the central line according to the position information and practical pen width of the sampling point; obtaining the filling gray value of a corresponding pixel point through the position information and the longitudinal pen width of each point on the central line; and filling corresponding pixel points to display handwriting with a style of writing. By adopting the method, handwriting is configured into a bitmap and the bitmap is transmitted to a bottom layer pattern module for displaying by directly operating the bottom layer pattern module without drawing any complex curve, so that pattern processing of a system is avoided, the processing speed of style of writing is increased, and smooth writing experience is brought to a user.

Description

technical field [0001] The invention relates to handwriting input technology, in particular to a method for realizing handwritten original handwriting. Background technique [0002] With the continuous advancement of technological development, many electronic devices with handwriting input systems have begun to enter the market, such as mobile phones, e-books, and tablet computers with handwriting functions. [0003] Take the handwriting tablet computer as an example. It is integrated with a handwriting input system, which has replaced the traditional keyboard input and is easier to meet the needs of mobile office in an all-round way. The text or graphics are directly displayed on the display interface of the tablet computer. [0004] But the handwriting processing method that the handwriting input system of tablet computer on the market adopts mainly contains following two kinds: [0005] The first is to connect the points passed by the stylus into a line to form handwrit...
