Embodiment 1

[0024] figure 1 A schematic flowchart showing a display method for realizing handwriting input on a touch screen provided by the present invention, figure 2 A schematic diagram of the final display effect based on the display method provided by the present invention is shown. The display method for realizing handwriting input on the touch screen provided by this embodiment includes the following steps.

[0025] S101. Obtain the pixel size value S of the display screen p and the target pen thickness value.

[0026] In step S101, the pixel point size value S p is the size of the minimum display unit (ie pixel dot) in the display screen for displaying the final written stroke graphics (ie subsequent line segment graphics), which can be obtained by reading the hardware parameters of the display screen. The target pen thickness value is closely related to the thickness display degree of the final written stroke figure, which may be an input preset value or a default value.

Abstract

The invention relates to the technical field of computer graphic processing and discloses a display method and display device for realizing hand input on a touch screen. Pen sizes of write tracks are set by carrying out pressure simulation processing on touch coordinate points, finally displayed write stroke graphs are enabled to be real and beautiful, even if the hand input is carried out by employing a finger, the written character graphs are as beautiful as those written by employing a brush pen, the better experience is provided for a user, and the method and the device are convenient for practical popularization and application.

Description

technical field [0001] The present invention relates to the technical field of computer graphics processing, in particular to a display method and a display device for realizing handwriting input on a touch screen. Background technique [0002] Since the touch screen can be integrated with the display screen and replace the keyboard to input information, it has also become one of the necessary devices for current electronic devices, such as mobile phones and tablet computers. With the popularity of touch screens, the wide application of handwriting input has been driven. As an important interactive link of handwriting input, original handwriting is gradually favored by the majority of users. The original handwriting writing technology is on the electronic device, according to a series of coordinate data received by the touch screen, simulating the curve trajectory used for pen writing on the paper, and finally drawing the graphic pattern technology that the user expects to s...
