[0033] The application scenarios of the embodiments of the present disclosure are explained below:

[0034] The text animation generation method provided by the embodiments of the present disclosure can be applied to an application program (APP, Application) with text animation generation functions, such as video editing application programs, animation editing application programs, etc. More specifically, it can be applied to the application scenario of adding text animations to a target video during the process of video editing.

Among them, when the execution entity is a terminal device, the terminal device executes the method provided by this embodiment by running the above-mentioned application program; when the execution entity is a server, the server side of the above-mentioned application program with text animation generation functions can run partially or entirely on the server, and execute the method provided by this embodiment on the server side, while the terminal device runs the client of the application program. Based on the server-client communication between the server and the terminal device, the terminal device can obtain the execution result of the method provided by this embodiment and display it as needed.

[0035] Among them, in some embodiments, the terminal device or the server can implement the text animation generation method provided by the embodiments of the present disclosure by running various computer-executable instructions or computer programs. For example, the computer-executable instructions can be program-level commands, machine instructions, or software instructions.

Among them, the cloud service can be an interactive processing service for the terminal device to call.

[0036] Figure 1This is an application scenario diagram of the text animation generation method provided by the embodiments of the present disclosure. Refer to Figure 1 As shown in

[0037] Taking a terminal device as an example, a target application with text animation generation function runs in the terminal device. The user inputs the text to be processed through the interaction interface of the target application. After that, the terminal device adds animation effects to the text to be processed through a previously or subsequently selected text animation template, so as to generate an animation whose outline and position can change over time, that is, a text animation. For example, as shown in the figure, after the user inputs the text "ABC" and selects the text animation effect #1, the terminal device generates a corresponding text animation through the target application, that is, an animation in which the outlines of the characters "A", "B", and "C" in the text change over time.

[0038] The embodiments of the present disclosure provide a text animation generation method to solve the above problems.

[0039] Refer to Figure 2 , Figure 2 This is a flowchart of the text animation generation method provided by the embodiments of the present disclosure. Figure 1 The method of this embodiment can be applied to a terminal device or a server. The text animation generation method includes:

[0040] Step S101: Obtain the input text, where the input text includes at least one text character.

[0041] Step S102: According to the input text, obtain the font data corresponding to the text characters in the input text. The font data includes the vector information corresponding to the text characters and the text animation information. The vector information is used to represent the standard character outline of the text characters, and the text animation information is used to control the deformation of the text characters.

[0042] Exemplarily, refer to Figure 1As shown in the schematic diagram of the application scenario, first, the terminal device receives the text input by the user, i.e., the input text, by running the target application and through the interactive interface of the target application. The input text includes at least one text character, and the text character can be any identifier such as a word, letter, number, expression, etc. Specifically, for example, the content of the input text is "The weather is good!". Then the input text is composed of five text characters: "天", "氣", "不", "错", and "!". Of course, in another possible implementation, the text characters may not include punctuation, that is, the above-mentioned input text is composed of four text characters: "天", "氣", "不", and "错", which can be set as needed.

[0043] After that, based on the above input text, the terminal device obtains the font data corresponding to each text character in the input text. The font data can be stored in the program file of the target application, that is, stored locally on the terminal device. The terminal device directly obtains the font data of the above text characters by reading the program file. In another possible implementation, the font data is stored in the cloud, such as the server of the target application. By retrieving the above text characters in the cloud, the corresponding font data is obtained. The font data can be designed and generated in advance for common text characters. The specific production method of the font data can be set as needed and will not be specifically limited here. Further, in the font data, vector information and text animation information corresponding to the text characters are included. The vector information is used to represent the standard character outline of the text character, and the text animation information is used to control the deformation of the text character. In one possible implementation, the text animation information is used to represent the maximum deformation vector for the standard character outline. Specifically, the vector information can be a kind of outline information used to describe the font outline. Different fonts can be distinguished through the vector information, and characters of different fonts correspond to different vector information. In one possible implementation, the vector information includes at least two contour identifiers, and the contour identifiers are used to represent the coordinates of the contour points that make up the standard character outline of the text character. That is, the vector information corresponding to the text character is a set of coordinate points, and each coordinate point corresponds to a contour point, so as to describe the font outline through the set of coordinate points. Among them, the contour points include the first contour points located on the standard character outline and the second contour points located outside the standard character outline. The first contour points are the drawing points of the standard character outline, and the second contour points are the control points for controlling the line shape between two drawing points. Specifically, the drawing points are the points used to draw irregular lines. By connecting multiple first contour points in sequence, an irregular line can be formed, that is, the standard character outline. And the second contour points are points located outside the standard character outline, that is, the control points in the Bezier curve. Through this control, the shape of the line between two drawing points can be adjusted. The specific implementation method of representing the font outline through drawing points and control points will not be elaborated here. The text animation information is a kind of information used to describe the change relative to the standard character outline. Specifically, that is, the text animation information is used to represent the maximum deformation vector for the standard character outline. In one possible implementation, the text animation information includes offset identifiers corresponding one by one to each contour identifier, and the offset identifiers are used to represent the offset vectors relative to the corresponding contour points, that is, the offset distance and direction relative to each contour point of the standard character outline. Based on the text animation information and the above vector information, another deformed font outline, that is, the maximum deformation vector of the standard character outline, can be determined.The text animation information corresponds one-to-one with the text characters. Therefore, each text character corresponds to a deformed font outline, that is, the maximum deformation vector for the standard character outline. In subsequent steps, the outline of the text font can vary between the standard font outline and the deformed font outline described above, thereby achieving an animation effect for the character.

[0044] Figure 3 FIG. is a schematic diagram of vector information and text animation information provided by an embodiment of the present disclosure. The following will be described in conjunction with Figure 3 the above steps. As Figure 3 shown, by way of example, the vector information is a set of coordinates of the contour points describing the standard character outline L1 of the text character, such as the points p1, p2, p3, and p4 shown in the figure. Among them, p1, p2, and p3 are the first contour points, and p4 is the second contour point. The text animation information includes offset vectors for each of the above contour points. For example, the offset vector v1 corresponding to the p1 point, the offset vector v2 corresponding to the p2 point, the offset vector v3 corresponding to the p3 point, and the offset vector v4 corresponding to the p4 point shown in the figure. According to the offset vectors included in the above text animation information, another contour line L2 can be obtained, that is, the contour line corresponding to the maximum deformation vector. The content of the animation formed by the text font later is the process of the contour line of the text font moving between the contour line L1 and the contour line L2.

[0045] Step S103: Generate a text animation of the input text according to the font data, wherein the character outlines of at least two text characters in the text animation change with time according to different change rules.

[0046] By way of example, after obtaining the font data based on the above steps, since the font data contains text animation information corresponding to the text characters, based on the vector information and text animation information corresponding to each text character, an independent animation corresponding to the text font can be generated, and the combination of the independent animations corresponding to each text character is the text animation of the input text. In the specific implementation process, first, according to the font data, each text character is drawn as a character bitmap at different time nodes. For example, if the text animation is an animation video or a GIF with a duration of one second and 10 frames per second, then for each text byte in the input text, a corresponding 10-frame character bitmap is generated. Then, the character bitmaps of the text bytes corresponding to the generated sequence are combined into one animation frame. In this way, 10 animation frames can be obtained, and then based on the 10 animation frames, a text animation with a duration of 1 second and a frame rate of 10 frames per second is generated. In the above process, since the character bitmap corresponding to each text character in the input text is independently generated based on its own text animation information, the character outlines of the text characters in the generated text animation can change with time according to different change rules, achieving an independent animation effect for each text character.

[0047] By obtaining input text, the input text includes at least one text character; according to the input text, obtaining font data corresponding to the text characters in the input text, the font data includes vector information and text animation information corresponding to the text characters, wherein the vector information is used to represent the standard character outline of the text characters, and the text animation information is used to control the deformation of the text characters; according to the font data, generating a text animation of the input text, wherein the character outlines of at least two text characters in the text animation change with time according to different change rules. By obtaining font data containing text animation information corresponding to different characters, and using the characteristic that the text animation information can represent the maximum deformation vector of the standard character outline for a single character, the character outlines of the text characters in the generated text animation change with time according to different change rules, so as to achieve an independent animation effect for a single character, and further improve the flexibility and visual expressiveness of the text animation.

[0048] Reference Figure 4 , Figure 4 is a schematic flowchart of a text animation generation method provided by an embodiment of the present disclosure Figure 2 . This embodiment further refines step S103 on the basis of the embodiment shown in Figure 2 . The text animation generation method includes:

[0049] Step S201: Obtain input text, and the input text includes at least one text character.

[0050] Step S202: According to the input text, obtain font data corresponding to the text characters in the input text, the font data includes vector information and text animation information corresponding to the text characters, wherein the vector information is used to represent the standard character outline of the text characters, and the text animation information is used to control the deformation of the text characters.

[0051] Step S203: Generate target signed distance field data corresponding to a time series according to the font data of the target text character.

[0052] Step S204: Draw a character bitmap corresponding to the time series according to the target signed distance field data corresponding to the time series.

[0053] Step S205: Generate a text animation of the target text character based on the character bitmap corresponding to the time series.

[0054] Exemplarily, signed distance field data, also known as Signed Distance Field (SDF) map, is a kind of map data that represents the distance between a pixel or a voxel and the surrounding pixels or voxels. Among them, if a certain pixel or voxel is inside the object, its distance value is negative; if it is outside the object, the distance value is positive; if it is exactly on the object boundary, the distance value is zero. This representation method enables the SDF map to accurately describe the shape and contour of the object. Specifically, in this embodiment, the target text character is at least one text character in the input text. In a specific implementation manner, each text character in the input text can be determined as the target text character in sequence or simultaneously, and subsequent processing steps are executed to generate the text animation of each target text character. Specifically, taking the case of processing a specific target text character as an example, first, a time series is generated, or a pre-generated time series is obtained. This time series can have a specified duration and / or a specified number of time nodes. Through this time series, the frame rate and duration of the subsequent generated text animation can be controlled. The specific generation method and implementation manner of the time series can be set as needed and will not be elaborated here. Among them, further, the time series includes at least two time nodes, such as N time nodes. In a possible implementation manner, this time series is corresponding to the input text, that is, the terminal device generates a time series including N time nodes based on this input text. Each text character in the input text shares this time series and generates N signed distance field data respectively, that is, the target signed distance field data. In another possible implementation manner, each text character corresponds to a time series, that is, in a possible implementation manner, different text characters correspond to time series with different durations and numbers of time nodes. In this embodiment, taking the case where each text character corresponds to the same time series as an example, based on this time series, the target signed distance field data corresponding to the target text character is generated. For example, if the time series contains 10 ordered time nodes, the target signed distance field data corresponding to this time series includes 10 signed distance field data corresponding one-to-one to the time nodes, that is, 10 SDF maps are generated, and each SDF map corresponds to one time node in the time series.

[0055] Furthermore, in a possible implementation manner for the process of generating the above-mentioned target signed distance field data, the content recorded in the text animation information is related to the content in the signed distance field data. The corresponding signed distance field data can be generated by inputting the text animation information into a corresponding processing function. Specifically, for example, the text animation information represents the maximum deformation vector for the standard character contour. Each time node in the time series is mapped to an ordered serial number within a finite range, and then each serial number is mapped to an offset. After that, on the basis of the maximum deformation vector, the offset mapped by the serial number is added respectively, and an offset sequence related to the time series can be obtained, that is, the target signed distance field data corresponding to the time series.

[0056] In another possible implementation manner, as Figure 5 shown, the specific implementation manner of step S203 includes:

[0057] Step S2031: For the target time node, obtain the corresponding first drawing parameter, and the first drawing parameter is used to represent the weighting coefficient of the maximum deformation vector for the standard character contour at the target time node.

[0058] Step S2032: According to the first drawing parameter and the text animation information in the font data corresponding to the target text character, obtain the actual offset information, and the actual offset information represents the actual deformation amount of the standard character contour for the target text character.

[0059] Step S2033: According to the actual offset information and the vector information, obtain the target signed distance field data corresponding to the target time node.

[0060] Among them, the target time node can be any time node in the time series, that is, for any time node in the time series, the above steps can be used for processing. Exemplarily, for the target time node, the first drawing parameter having a mapping relationship therewith is obtained. The first drawing parameter is used to characterize the weighting coefficient of the maximum deformation vector for the standard character contour under the target time node. Among them, the first drawing parameter is used to indicate the deformation amount of each contour point under the target time node, that is, the weighting coefficient of the maximum deformation vector for the standard character contour. Specifically, the first drawing parameter can be a coefficient value, such as 0.8; it can also be a coefficient vector, such as [0.5, 0.8], that is, a coefficient describing both size and direction changes. In a more specific embodiment, for example, the time series includes multiple time nodes such as time node T1 and time node T2. For time node T1, that is, taking time node T1 as the target time node, its corresponding weighting coefficient is 0.8; for time node T2, that is, taking time node T2 as the target time node, its corresponding weighting coefficient is 0.72. Then, according to the first drawing parameter and the text animation information in the font data corresponding to the target text character, the actual offset information is obtained. For example, multiplying the above first drawing parameter (weighting coefficient) by the maximum deformation vector characterized by the text animation information can obtain the actual offset information. This first drawing parameter is equivalent to a control parameter for the deformation amount of the contour of the target text character. Exemplarily, after obtaining the first drawing parameters corresponding to the above time nodes, calculate to control the change of the font contour by changing the first drawing parameters corresponding to different target time nodes. Finally, for each time node, according to the actual offset information and the vector information, such as calculating the vector sum of the two, the signed distance field data corresponding to each time node is generated, and finally the target signed distance field data corresponding to the time series is obtained.

[0061] Further, the first drawing parameter can be a value corresponding one-to-one with the target time node. When the target time nodes in the time series are linearly distributed, the first drawing parameter also changes linearly. For example, the first drawing parameters for the same time series are 0.1, 0.2, 0.3, etc. In another possible implementation, the first drawing parameter can have a more complex variation law based on the target time node, so as to achieve a more complex text animation effect. In one possible implementation, as Figure 6 shown, the specific manner of step 2031 includes:

[0062] Step 2031-1: Obtain the first animation configuration information for the input text. The first animation configuration information is used to characterize the variation law of the weighting coefficient of the maximum deformation amount for the standard character contour over time.

[0063] Step 2031-2: Obtain first drawing parameters according to the first animation configuration information and the target time node.

[0064] Exemplarily, the first animation configuration information is information characterizing the variation law of the weighting coefficient of the maximum deformation amount with time for the input text, that is, the shape change information of all characters of the input text. This first animation configuration information can be determined based on an animation template. That is, after the user selects a certain text animation template in the target application, the first animation configuration information stored in the text animation template can be obtained. The variation law of the weighting coefficient with time characterized by this first animation configuration information can be linear or non-linear, so that the animation effect of the final text animation's contour change does not present a non-linear change effect, thereby improving the visual perception of the text animation.

[0065] In another possible implementation manner, the font data further includes second animation configuration information, which is used to characterize the variation law of the weighting coefficient of the maximum deformation amount of the standard character contour for the target text character, as Figure 7 shown, the specific manner of step 2031 includes:

[0066] Step 2031-3: Obtain the second animation configuration information for the target text character.

[0067] Step 2031-4: Obtain first drawing parameters according to the second animation configuration information and the target time node.

[0068] Exemplarily, in another possible implementation manner, in the font data of the target text character, there is also second animation configuration information characterizing the variation law of the weighting coefficient of the maximum deformation amount of the standard character contour for the target text character. Different from the first animation configuration for the input text, this second animation configuration information is the configuration information for a single text character. Through this second animation configuration information, the weighting coefficient of a single target text character at different time nodes can be realized, so that different target texts can have different weighting coefficients for the maximum deformation amount of the standard character contour at the same time node, and thus a more flexible and variable text animation mode can be realized.

[0069] Figure 8 FIG. is a schematic diagram of a process for determining actual offset information based on the second animation configuration provided by an embodiment of the present disclosure. The above solution will be further introduced below in conjunction with Figure 8 as Figure 8As shown, exemplarily, for the target text character "A" in the input text, its font outline is composed of multiple outline points. Taking the outline points p1, p2, and p3 shown in the figure as examples, the maximum outline vectors corresponding to the outline points p1, p2, and p3 are V1, V2, and V3 respectively. On this basis, according to the second animation configuration information of the target text character "A", at time node t1, the first drawing parameter val_p1 corresponding to the outline point p1 = 0.5, the first drawing parameter val_p2 corresponding to the outline point p2 = 0.6, and the first drawing parameter val_p3 corresponding to the outline point p3 = 0.8. Schematically, according to the first drawing parameters corresponding to each outline point, the actual offset vectors (i.e., actual offset information, the same below) corresponding to the outline point p1 are obtained as v11, the actual offset vector v12 corresponding to the outline point p2, and the actual offset vector v13 corresponding to the outline point p3; at time node t2, the first drawing parameter corresponding to the outline point p1 is 0.7, the first drawing parameter corresponding to the outline point p2 is 0.8, and the first drawing parameter corresponding to the outline point p3 is 0.4. According to the first drawing parameters corresponding to each outline point, the actual offset vectors (i.e., actual offset information, the same below) corresponding to the outline point p1 are obtained as v21, the actual offset vector v22 corresponding to the outline point p2, and the actual offset vector v23 corresponding to the outline point p3. And so on. At different time nodes, the actual deformation amounts corresponding to each outline point can change independently, so that the font outline of the target text character "A" composed of the above outline points can achieve more complex shape changes, thereby improving the diversity of the motion styles and visual expressiveness of each text character in the finally generated text animation.

[0070] Further, exemplarily, the text animation information includes a vector set composed of a target number of vector values. The target number is the number of outline points of the standard character outline of the target text character, and each vector value corresponds one-to-one to an outline point of the standard character outline of the text character. As Figure 9 shown, the specific implementation manner of step S2032 includes:

[0071] Step S2032-1: Obtain the offset vectors corresponding to each outline point according to the product of each vector value in the vector set and the first drawing parameter;

[0072] Step S2032-2: Obtain the actual offset information according to the offset vectors corresponding to each outline point.

[0073] Exemplarily, the text animation information includes a vector set composed of a target number of vector values. Each vector value corresponds to a contour point of the standard character outline of a target text character and is used to describe the deformation of the contour point. The first drawing parameter can be used to indicate the deformation amount (weighting coefficient) of each contour point at the target time node. The first drawing parameter can be a coefficient value or a coefficient vector. After obtaining the first drawing parameter, based on the same time node, calculate the product of the first drawing parameter and the corresponding vector value to obtain the offset vector of the contour point corresponding to the vector value. Furthermore, based on the offset vectors corresponding to each contour point, obtain the actual offset information.

[0074] Furthermore, in a possible implementation manner, the font data further includes color animation information, which is used to represent the starting color value and the ending color value of the font color of the text character of the clock hand; for example, both the starting color value and the ending color value are represented by RGB color values. Then, according to the above color animation information in the font data, during the process of forming the text animation, control the font color to also change, so that in the generated text animation, the font colors of the character outlines of at least two text characters change with time according to different change rules.

[0075] Specifically, for the above situation, that is, when the font data includes the vector information, text animation information, and color animation information corresponding to the text character, the specific implementation manner of step S204 includes:

[0076] Step S204A: Obtain the color change data corresponding to the time series;

[0077] Step S204B: Draw the character bitmap corresponding to the time series according to the target signed distance field data and the color change data corresponding to the time series.

[0078] Exemplarily, referring to the step of generating the target signed distance field data corresponding to the time series according to the font data of the target text character in step S203, in this embodiment, according to the font data of the target text character, obtain the color change data corresponding to the time series. Specifically, for example, first, for each target time node in the generated time series, obtain the corresponding second drawing parameter, where the second drawing parameter is used to represent the weighting coefficient for the font color at the target time node; then, according to the second drawing parameter, the starting color value, and the ending color value in the font data corresponding to the target text character, obtain the actual color information, where the actual color information represents the actual font color of the target text character at the target time node. Finally, according to the target signed distance field data and the color change data corresponding to the time series, perform font rendering to draw the character bitmap corresponding to the target time node, and repeat or execute the above steps in parallel, and then obtain the character bitmap corresponding to the time series.

[0079] In this embodiment, by using the starting color value and the ending color value in the sub-font data, independent control of the font color of each text character in the input text is achieved, so that the generated text animation has a changing visual expression.

[0080] In this embodiment, the implementation manners of steps S201 - S202 are the same as those of steps S101 - S102 in the embodiment shown in this disclosure Figure 2 and will not be elaborated herein one by one.
