In this embodiment, when an instant messaging application (e.g., WeChat) running by an execution subject (e.g., the terminal device shown in fig. 1) of the method for generating a drawing detects that a user calls a drawing applet, the drawing applet is opened, and a canvas is called, where the canvas may be a canvas blank canvas. The picture can also be used as a canvas according to the selection of the user. The size of the canvas can be defaulted to the full screen size, and the size of the canvas can be adaptively adjusted according to the chat window. For example, the chat window is floated on the canvas, and the user can move or close the chat window at will without missing the conversation content while drawing. The window of the last conversation prior to switching to the widget may be detected as a floating displayed chat window. The canvas may have a variety of option icons such as an icon for setting a brush parameter, an eraser, a graphical marquee, an insertion tool, a trash can icon, a dismiss icon, save, export, edit, etc. Clicking on the insertion tool may display an edit menu, which may include inserting pictures, inserting text, etc.
And 202, in response to the detection of the touch sliding operation on the canvas, drawing a first graph on the canvas according to the touch sliding track and preset painting parameters.
In this embodiment, the touch slide track of the user is displayed on the canvas, so as to obtain the first graph. The painting parameters can be preset or adjusted after painting. The brushstroke parameter includes at least one of: material, thickness, transparency, color. The material may include: pencils, pens, oil pencils, and the like.
The line drawn between each start touch and stop touch is one stroke. Each line is saved in a line list. When the user selects a line in the list of lines, the selected trajectory is highlighted. The list of lines may be displayed on the canvas for selection by the user. After the lines are selected, the color, thickness, etc. of the lines can be adjusted. In addition to selecting a line in the list of lines, the line can be selected by clicking any point on the line. At least one line may also be selected by a selection box, which may select a segment within the line.
And step 203, in response to detecting the undo operation on the second graph, deleting the second graph from the graphs to obtain a third graph.
In the present embodiment, the second graphic is a graphic to be deleted. The third pattern is a pattern remaining after the second pattern is deleted from the first pattern. The second graphic may be the most recently drawn line and the undo operation may be the most recently saved line in the default undo line list. The user may also select tracks to undo from the list of lines. Optionally, the second graphic to be revoked may also be selected directly in the canvas. The second graphic may be a single line or a combination of lines. One line can be selected by touching any point on the line. The line to be dismissed may be dragged into the trash. The deleted lines are stored in the garbage can and can be restored from the garbage can. All lines can also be dismissed, i.e., the canvas is emptied. Optionally, the line may also be dismissed by some gesture operations, e.g., long pressing the line or re-pressing the line. The second graph can also be a graph in a certain area, and all lines in the area are deleted.
And step 204, responding to the detection of the export operation, generating an instant message comprising a third graph and sending the instant message to the opposite terminal.
In this embodiment, the canvas has a lead-out option, and the user forms a picture with the graphics on the canvas after clicking to generate an instant message, and sends the instant message to the other terminal. The instant message is exported by default to the last dialog box. Alternatively, they may be exported to other users or stored locally. Optionally, export to other applications.
According to the method provided by the embodiment of the application, the applet is called in the instant messaging application program for drawing, the original instant messaging application program does not need to be quitted, drawing can be carried out, the drawing is finished and sent, local storage is not needed, convenience and communication efficiency of network communication are improved, and storage space is saved. The problem that drawing cannot be flexibly and quickly carried out in the network conversation process is solved, and the network communication efficiency is improved.
With further reference to FIG. 3, a flow diagram of yet another embodiment of a method for generating a drawing is shown. The flow of the method for generating the drawing comprises the following steps:
in response to receiving a drawing request, a canvas is obtained, step 301.
Step 301 is substantially the same as step 201, and therefore will not be described again.
And 302, in response to the detection of the touch sliding operation on the canvas, drawing a first graph on the canvas according to the touch sliding track and preset painting parameters.
In this embodiment, step 302 is substantially the same as step 202, and therefore is not described again.
In some optional implementations of the embodiment, in response to detecting a long-press operation or a re-press operation of the user, the thickness of the brush (or the brush made of other materials) is adjusted according to the operation time length. The long press refers to that the time of a certain point of the touch screen exceeds a preset time, and the re-press refers to that the pressure of the certain point of the touch screen exceeds a preset pressure value. The brush may be thickened as the user holds down at a certain point in time until it becomes the thickest brush, and may be tapered if the long press continues. Similarly, the brush thickness may be increased by continually pressing a point until the thickest brush is reached, and the brush may be tapered if the press is continued. The scheme can quickly adjust the thickness of the paintbrush without switching to a paintbrush option, so that the drawing process is simpler and more convenient.
Step 303 is substantially the same as step 203, and therefore is not described in detail.
In some optional implementations of this embodiment, an editing tool may be selected to edit the graphics on the canvas, the editing tool including at least one of: rubber, a graphic selection frame and an insertion tool. The rubber can be used for erasing the existing lines, and the line in one area can be selected by the graphic selection frame to be uniformly edited, for example, the line in a circular area is selected to change the color, the thickness and the like. The insertion tool may insert pictures, text, emoticons, etc. Through the editing tool, the idea of the user can be more accurately expressed by drawing, the key points are highlighted, and the meaning of the drawing is easy to understand by the opposite side.
And 304, in response to the detection of the export operation, generating an instant message comprising a third graph and sending the instant message to the opposite terminal.
Step 304 is substantially the same as step 204 and thus will not be described again.
In some optional implementations of the present embodiment, a correspondence between a position of the touch slide trajectory and time is recorded. And generating an instant message according to the corresponding relation and the third graph so that the opposite terminal can display the drawing process of the graph according to the corresponding relation.
The user records the time each time the finger draws a point while sliding on the touch. The function of recording the screen is realized. The instant message records not only the graph, but also the time of each point drawn on the canvas, and the receiver can select to play the drawing, thereby displaying the drawing process of the user. Therefore, the opposite side can clearly know the drawing sequence, and the contents expressed by the drawing can be clearer.
In some optional implementations of the embodiment, the narration voice is recorded during the touch sliding process. And generating an instant message according to the explication voice and the third graph so that the opposite terminal can synchronously play the explication voice when the drawing process of the graph is displayed.
The user can explain the side painting in the drawing process and explain the recording. Recording can be started by default while the canvas is opened, and recording can be started by clicking a recording key on the canvas. The instant message records not only the graph but also the explanation, and the opposite side terminal can more clearly understand the intention of the user through the explanation recording when viewing the picture. The recording can be stored simultaneously with the corresponding relation between the position and the time, or only the recording can be stored. The communication efficiency is further improved through the combination of the explanation and the drawing of the user.
In this embodiment, the user may click on the save icon on the canvas and select to store the third graphic under the account of the logged-in instant messaging application. And may also be saved locally. And after the user logs in the account of the instant messaging application program, the user can still find the self-drawn graph by virtue of the account even if the terminal equipment is replaced. In response to detecting a user's work-viewing operation, displaying a list of works under the user's account that has logged into the instant messaging application. The list of works may be displayed in a thumbnail or list manner.
In some optional implementation manners of the embodiment, in response to receiving a picture sent by the other terminal, a graph is drawn on the picture according to the user touch sliding track and preset painting parameters. The picture sent by the other party can be received and edited on the basis of drawing of the other party, so that interaction between the two parties is realized, the communication efficiency is improved, and the interestingness is increased.
As can be seen from fig. 3, compared with the embodiment corresponding to fig. 2, the flow of the method for generating a drawing in this embodiment represents a step of storing the third graph below the account of the user that has logged into the instant messaging application, and adds an illustration and a drawing. Therefore, the scheme described in the embodiment can introduce more drawing related information, so that more comprehensive information exchange is realized, and the communication efficiency is improved.
With continuing reference to fig. 4a-4c, fig. 4a-4c are schematic diagrams of an application scenario of the method for generating a drawing according to the present embodiment. In the application scenario of fig. 4a, when a user a chats with a user B through a WeChat on a mobile phone, if the user B needs to be explained through drawing, the user a opens a blank canvas after calling an applet of the WeChat, and the canvas has some painting options and menu bars.
