[0002] Computer Aided Design (CAD) refers to the use of computers and their graphics equipment to help designers perform design work.

Of course, the above electronic devices can also be servers, for example, cloud servers.

[0028] The embodiments of the present application are described in detail below.

[0029] Figure 1 FIG. 1 is a flow chart of a font processing method provided in an embodiment of the present application. As shown in the figure, the font processing method includes:

[0030] 101. When it is detected that a preset position of a CAD interface is touched, target coordinate data corresponding to the preset position is acquired.

[0031] Among them, the preset position can be set by the user or by system default. The electronic device can perform touch detection through a touch display screen. When the electronic device detects that the preset position of the CAD interface is touched, it can obtain the target coordinate data corresponding to the preset position. The target coordinate data can be the coordinate data corresponding to an area range or a point. For example, the coordinate data of an area touched by the user can be used as the target coordinate data, or the coordinate data of the center of an area touched by the user can be used as the target coordinate data. In addition, the target coordinate data can also refer to the coordinates represented by the strokes of the font, and the corresponding contour is formed based on these coordinates. Based on the contour, the character recognition or font type recognition corresponding to the preset position can be realized. There may be characters at the preset position, or there may not be characters. If there are characters, the characters can have corresponding font types. Primitive recognition or character recognition can be realized using the target coordinate data corresponding to the preset position.

[0032] Optionally, the above step 101, obtaining the target coordinate data corresponding to the preset position, may include the following steps:

[0033] 11. Obtaining target touch parameters for the preset position;

[0034] 12. When the target touch parameter meets the preset requirement, identify the target graphic element corresponding to the preset position;

[0035] 13. Obtain the target coordinate data of the target primitive at the preset position.

[0036] The preset requirements may be preset or set by the system default. The target touch parameter may be at least one of the following: number of touches, touch area, touch force, touch duration, etc., which are not limited here. For example, the target touch parameter may be the maximum touch force when the touch area is within a preset area range. For another example, the target touch parameter may be the average touch force when the touch duration is within a preset duration range. The preset area range and the preset duration range may be set by the user or set by the system default.

[0037] In a specific implementation, the electronic device can obtain target touch parameters for a preset position. When the target touch parameters meet the preset requirements, the target graphic element corresponding to the preset position can be identified, and then the target coordinate data of the target graphic element at the preset position can be obtained. In this way, accidental touches can be prevented, and the coordinate data of the preset position can be obtained based on the touch operation.

[0038] 102. Obtain a target font type corresponding to the target coordinate data.

[0039] Among them, different coordinate data can correspond to different font types. In the embodiment of the present application, the font type can be at least one of the following: Songti, Kaiti, Lishu, Caoshu, Youyuan, etc., which are not limited here. In a specific implementation, the target font type can be realized based on the target coordinate data, that is, different fonts have different text styles or trends. It is equivalent to font file recognition, identifying whether there is a character at a preset position, or the font type of the font. The target font type can correspond to the font type of at least one character. The target coordinate data can correspond to at least one character. The target font type may include one or more font types.

[0040] Optionally, the above step 102, obtaining the target font type corresponding to the target coordinate data, may include the following steps:

[0041] A21, acquiring character data of the CAD interface according to the target coordinate data;

[0042] A22, extracting characters from the character data to obtain a plurality of characters;

[0043] A23, classifying the multiple characters to obtain at least one class;

[0044] A24, determining the number of characters in each of the at least one class to obtain at least one number of characters;

[0045] A25. Use the font type of the type of characters that appear most in the at least one character quantity as the target font type.

[0046] Among them, the electronic device can obtain character data of a partial area or the entire area of ​​the CAD interface. For example, it can be character data of the CAD interface within a specified range centered on the target coordinate data. The specified range can be pre-set or system default. Then, characters can be extracted from the character data to obtain multiple characters. The multiple characters can also be classified according to font type to obtain at least one class. Furthermore, the electronic device can determine the number of characters in each class in at least one class to obtain at least one character number, and the font type of the class with the most characters in the at least one character number is used as the target font type. In this way, the font type required by the user can be determined based on the mainstream font type of the CAD interface.

[0047] Optionally, the above step 23, classifying the multiple characters to obtain at least one class, may include the following steps:

[0048] A231, extracting features from each of the multiple characters to obtain multiple feature sets, where each character corresponds to a feature set;

[0049] A232. Input the multiple feature sets into a preset neural network model to obtain the at least one class.

[0050] Among them, in the embodiment of the present application, the preset neural network model can be pre-set or system default, and the preset neural network model can be at least one of the following: convolutional neural network model, recurrent neural network model, fully connected neural network model, etc., which are not limited here. Each feature set may include at least one feature, and the feature may include at least one of the following: feature point, feature vector, radian, feature contour, etc., which are not limited here. In actual applications, sample feature sets of each type of font can be obtained, and each sample feature set can correspond to a category label. These sample sets are then input into the initial neural network model for training. After the initial neural network model converges, the preset neural network model can be obtained.

[0051] In a specific implementation, feature extraction can be performed on each of the multiple characters. Of course, before feature extraction, these characters can also be preprocessed, and feature extraction can be performed after preprocessing. The preprocessing can include at least one of the following: noise reduction, amplification, ghosting removal, etc., which are not limited here. Then, multiple feature sets are obtained, each character corresponds to a feature set, and the multiple feature sets are then input into a preset neural network model to obtain at least one class. In this way, intelligent classification of characters can be achieved.

[0052] Optionally, the above step 102, obtaining the target font type corresponding to the target coordinate data, may include the following steps:

[0053] B21, obtaining a screenshot of a preset range of the target coordinate data;

[0054] B22, extracting graphic elements from the screenshot to obtain at least one graphic element;

[0055] B23, extracting features from the at least one primitive to obtain a target primitive feature set;

[0056] B24. Determine the target font type corresponding to the target graphic element feature set.

[0057] Among them, the preset range can be preset or defaulted by the system. For example, the preset range can be a preset radius range with the center of the target coordinate data as the center of the circle. The primitive feature set can include at least one primitive feature. The primitive feature can include at least one of the following: primitive type, primitive number, primitive arc, number of lines, etc., which are not limited here. The mapping relationship between the preset primitive feature set and the font type can be stored in advance, and then the target font type corresponding to the target primitive feature set can be determined based on the mapping relationship. In this way, a font type suitable for the primitive can be obtained.

[0058] 103. Determine a reference font library corresponding to the preset position from a preset database, where the reference font library includes reference fonts of at least one font type.

[0059] Among them, the preset database can be pre-stored in the electronic device, and fonts of various font types and various font libraries can be stored in the preset database. Different positions can correspond to different font libraries. The mapping relationship between the position and the font library identifier can be pre-stored in the electronic device, and then the reference font library corresponding to the preset position can be determined. The preset database includes a reference font library. The reference font library can be a font library generated by coordinate point data, and the reference font library can include one or more characters, and each character can correspond to a set of coordinate point data. The target font type may be a font type that the user does not need to render, and the font type in the reference font library may be a font type that the user needs to render. The reference font library can store a limited number of characters. Of course, the reference font library can also be selected by the user, and the reference font library can be a font that the user needs to obtain a rendering effect.

[0060] Optionally, the above step 103, determining the reference font library corresponding to the preset position from the preset database, may include the following steps:

[0061] 31. Determine the target font library identifier corresponding to the preset position according to the mapping relationship between the preset position and the font library identifier;

[0062] 32. Acquire a reference font library corresponding to the target font library identifier from the preset database.

[0063] The electronic device may pre-store a mapping relationship between a preset position and a font library identifier, and then determine the target font library identifier corresponding to the preset position according to the mapping relationship, that is, obtain a reference font library corresponding to the target font library identifier from a preset database.

[0064] 104. Acquire a target font corresponding to the target font type from the reference font library.

[0065] Among them, the electronic device can obtain a target font corresponding to the target font type from a reference font library, and can also obtain content to be displayed, and display it in the target font. For example, the target font can be displayed at a preset position, or the target font can be displayed at other positions. Furthermore, the target font can be used to replace the characters corresponding to the preset position. In an embodiment of the present application, one or more characters can be rendered, so that characters of different types can have the same font type. For example, assuming that there is a character "A" at a preset position, and the A is in ttf format, it can be converted into a font type "A" consisting of a finite number of coordinate point data.

[0066] In a specific implementation, the target font can be a font composed of coordinate point data. Each coordinate point data can correspond to a coordinate point and can be represented by a dot. The dot can be solid or hollow. The size of the dot can be set by the user or by the system default. The size can be understood as the area of ​​a solid dot or the line width of a hollow dot. The amount of coordinate point data is related to the number of points. The more coordinate point data there is, the more points there are. The color of the dot can also be set by the user or by the system default.

[0067] In a specific implementation, the target font can be prepared in advance, and when used, there is no need to load the corresponding font library, and the target font can be directly called, thereby improving rendering efficiency.

[0068] Optionally, the above step 104, obtaining a target font corresponding to the target font type from the reference font library, may include the following steps:

[0069] 41. Obtain a font index of a font corresponding to the preset position according to the target font type, use the font index of the font as a query identifier, perform a query in the reference font library, and obtain a coordinate point index identifier;

[0070] 42. Determine corresponding coordinate data according to the coordinate point index identifier, and use the coordinate data as the target font.

[0071] In a specific implementation, the font index of the font corresponding to the preset position can be obtained according to the target font type, and the font index of the font is used as a query identifier to query in the reference font library to obtain the coordinate point index identifier, that is, to find the coordinate point index of the font to be rendered, and then determine the corresponding coordinate data according to the coordinate point index identifier, and use the coordinate data as the target font. In this way, the target font type can be rendered into the font type required by the user.

[0072] Optionally, the following steps may also be included:

[0073] A1. Pre-generate a vertex sequence of at least one font as a font index, and store the vertex sequence of the at least one font in the preset database, where each vertex sequence corresponds to a font index, and each font index corresponds to a font index identifier;

[0074] A2. Establishing a mapping relationship between the font index identifier and the coordinate point index identifier.

[0075] In a specific implementation, the vertex sequence of at least one font can be pre-generated as a font index, and the vertex sequence of at least one font can be saved in a preset database, each vertex sequence corresponds to a font index, and each font index corresponds to a font index identifier. Then a mapping relationship between the font index identifier and the coordinate point index identifier is established, so that the coordinate point data of the font that needs to be rendered can be quickly found later. That is, the vertex sequence of the font is pre-generated and saved in the database, and is directly read from the database when needed, which reduces the time required for real-time dynamic generation of the vertex sequence of the font and improves the generation efficiency.

[0076] To illustrate, in a specific implementation, an electronic device can use a font generation tool library (such as opentype.js) to pre-generate font coordinate point data for the used ttf format font library (such as Songti, Heiti, etc.), and then store these data in a database. When the front end needs to render the font, it can dynamically query the database to obtain the coordinate point data of the corresponding font, saving the process of real-time dynamic generation of fonts, and can load the required fonts on demand. There is no need to download all font libraries to the front end in advance and then generate the coordinate data of the font points and lines, saving the front-end network bandwidth requirements and improving performance and efficiency.

[0077] Optionally, in step 104, after acquiring a target font corresponding to the target font type from the reference font library, the following steps may also be included:

[0078] B1. Determine the target display frame size corresponding to the preset position;

[0079] B2. Obtain the content to be displayed;

[0080] B3, determining a first display parameter of the content to be displayed according to the target display frame size;

[0081] B4. Obtaining the target background color of the preset position;

[0082] B5. Determine a second display parameter corresponding to the target background color according to a preset mapping relationship between the background color and the display parameter;

[0083] B6. Display the content to be displayed according to the first display parameter and the second display parameter.

[0084] Among them, the electronic device can determine the target display box size corresponding to the preset position, and can also obtain the content to be displayed. The content to be displayed can be pre-set or added by the user. Then, the first display parameter of the content to be displayed can be determined according to the target display box size. The first display parameter can be at least one of the following: font size, font type, line spacing, column spacing, etc., which are not limited here. In a specific implementation, the number of characters of the content to be displayed can be obtained, and then the font size, line spacing, etc. can be adjusted.

[0085] Furthermore, the electronic device may pre-store a mapping relationship between a preset background color and a display parameter. The electronic device may also obtain a target background color at a preset position, and then, according to the mapping relationship between the preset background color and the display parameter, determine a second display parameter corresponding to the target background color, the second display parameter may be at least one of the following: font color, color temperature, etc., which are not limited here, and then, the content to be displayed may be displayed according to the first display parameter and the second display parameter.

[0086] It can be seen that the font processing method described in the embodiment of the present application is applied to an electronic device. When it is detected that a preset position of a CAD interface is touched, the target coordinate data corresponding to the preset position is obtained, the target font type corresponding to the target coordinate data is obtained, and a reference font library corresponding to the preset position is determined from a preset database. The reference font library includes reference fonts of at least one font type. The target font corresponding to the target font type is obtained from the reference font library. In a CAD environment, the font generation efficiency can be improved.
