Embodiment 1

[0028] The present embodiment provides a method for drawing graffiti spray based on a touch screen, through which the drawing effect of graffiti spray can be realized on a touch screen such as an electronic white screen, the drawing function of the touch screen can be improved, and the needs of users can be met; for example, figure 1 As shown, the drawing method of this embodiment specifically includes the following steps:

[0029] Step S0: Receive a setting instruction, and change the color and transparency of the sprayed image according to the setting instruction. The user pre-enters the painting interface of the touch screen, and clicks the graffiti spray function to customize the color and transparency of the graffiti spray to change the rendering effect of the sprayed image; the setting of the transparency determines the drawing corresponding to the sprayed image per unit time. Density, that is, the smaller the transparency, the fewer drawing points corresponding to the s...

Embodiment 2

[0044] This embodiment provides an electronic device, which includes a processor, a memory, and a computer program stored on the memory and running on the processor, and the processor implements the first embodiment when the processor executes the computer program touch screen-based graffiti spray drawing method; in addition, this embodiment also provides a storage medium on which a computer program is stored, and when the computer program is executed, the above-mentioned touch screen-based graffiti spray drawing method is implemented.

Abstract

The invention discloses a graffiti spray drawing method, device and storage medium based on a touch screen, wherein the drawing method includes step S1: obtaining the spraying signal formed by the user's touch action on the touch screen in real time; step S2: The spraying signal is analyzed to obtain the drawing range and drawing density corresponding to the touch action, and a corresponding spraying image is generated on the touch screen according to the drawing range and the drawing density. The invention can realize graffiti spray effect on the touch screen and increase the painting function of the touch screen.

Description

technical field [0001] The present invention relates to the technical field of touch electronic devices, and in particular, to a method, device and storage medium for drawing graffiti spray based on a touch screen. Background technique [0002] At present, the touch screen is widely used in various scenarios. Since the drawing tool of the electronic white screen is generally based on a hard pen, the drawn effect is presented as a line segment with the same density and uniform color distribution. Therefore, the drawing on the electronic white screen The function is generally limited to writing on the electronic white screen, or marking or annotating the content displayed on the electronic white screen. However, the current electronic whiteboard cannot simulate the effect of graffiti spray, which makes the painting function of the electronic whiteboard relatively simple and cannot meet the various painting needs of users. SUMMARY OF THE INVENTION [0003] In order to overco...
