Embodiment 1

[0031] figure 1 It is a schematic flow chart of a method for presenting line writing provided by Embodiment 1 of the present invention. This method is suitable for adjusting operations such as moving or zooming the original line writing formed by the user. Execution, the device can be implemented by hardware / software, and generally integrated in interactive electronic equipment.

[0032] It should be noted that the application scenario of the method for presenting line handwriting provided by the embodiment of the present invention is: in the operation interface of electronic equipment such as drawing, writing or highlighting, the user writes by touch or controls the brush with the mouse. If the original line is changed, the user may need to perform adjustment operations such as moving or scaling the original line. This adjustment operation is equivalent to eliminating the constructed original line and presenting a new line at the position corresponding to the adjustment opera...

Embodiment 2

[0049] Figure 2a It is a schematic flowchart of a method for presenting line handwriting provided by Embodiment 2 of the present invention. This Embodiment 2 is optimized based on the above-mentioned embodiment. In this embodiment, the original coordinate points that constitute the original line handwriting are further combined And the adjustment parameters currently acting on the original line handwriting, determine the set of target coordinate points needed to adjust the original line handwriting, the specific optimization is: obtain the original coordinate information of each handwriting point when the user draws and forms the original line handwriting, and form a set containing A set of original coordinate points for each of the original coordinate information, wherein each handwriting point in the original coordinate point set is arranged based on the generation time; analyze the user’s current adjustment operation on the original line handwriting, and determine the adjus...

Embodiment 3

[0096] Figure 3a It is a structural block diagram of an apparatus for presenting line handwriting provided in Embodiment 3 of the present invention. The device is suitable for adjusting operations such as moving or scaling the original line drawn by the user. The device can be implemented by hardware / software and is generally integrated in interactive electronic equipment. like Figure 3a As shown, the device includes: a target point determination module 31 , an intermediate handwriting generation module 32 and a handwriting smoothing processing module 33 .

[0097] Wherein, the target point determination module 31 is used to determine the set of target coordinate points required to adjust the original line-writing according to the original coordinate point set constituting the original line-writing and the adjustment parameters currently acting on the original line-writing;

[0098] Intermediate handwriting generation module 32, for based on described target coordinate poi...

Abstract

The invention discloses a line handwriting displaying method, a line handwriting displaying device, electronic equipment and a storage medium. The method comprises the steps of determining a target coordinate point set needed for adjustment of an original line handwriting according to an original coordinate point set composing the original line handwriting and an adjustment parameter currently acting on the original line handwriting; constructing and generating an intermediate line handwriting relative to the original line handwriting through a constructor function of a connected triangle in an OpenGL ES based on the target coordinate point set; and smoothing a handwriting starting point and a handwriting end point in the intermediate line handwriting to obtain a target line handwriting corresponding to a current adjustment operation. By use of the method, the adjusted target line handwriting can be effectively displayed when an adjustment operation is performed on the original line handwriting, thereby improving the response rate for displaying of the line handwriting; the problem of system carradoon of the electronic equipment is also effectively avoided in the line handwriting adjustment displaying process and the user experience of the electronic equipment is further effectively improved.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a method, device, electronic equipment and storage medium for presenting line handwriting. Background technique [0002] At present, interactive electronic devices (such as tablet computers, smart phones, and smart whiteboards, etc.) have been widely used in people's life, work, and study. With the continuous improvement of user needs, the functional applications integrated in electronic devices are becoming more and more abundant. For example, the functional applications such as drawing or writing integrated in electronic devices. Drawing and writing operations can be performed by touching or writing tools on the interface. [0003] Generally, after the user forms the handwriting by touching or writing tools in the above-mentioned applications, he can also perform adjustment operations such as zooming or moving the handwriting through gestures or corresponding opt...
