[0045] Step 110: Determine the font index tag of the corresponding emoticon in the emoticon atlas font based on the text data input by the user; wherein the emoticon atlas font is generated based on an integrated emoticon image and emoticon attribute data, the integrated emoticon image is obtained by merging multiple emoticon images, and the emoticon attribute data is generated based on the position information of each emoticon image in the integrated emoticon image.

[0046] Among them, text data includes strings and text fields, etc. In an embodiment of the present invention, an emoticon database can be imported to obtain multiple emoticon images in the emoticon database. The emoticon images in the emoticon database almost include all emoticons. Special emoticon images can be obtained and imported separately to improve the comprehensiveness of the integrated emoticon images, so that the emoticon collection fully includes the emoticons that may be used. In an embodiment of the present invention, a python tool script can be used to convert the imported emoticon images into a preset size, such as a 32X32 image, and import it into a Unity project.

[0047] In an embodiment of the present invention, the emoji attribute data includes the position information of each emoji image in the integrated emoji image, and the unique emoji code corresponding to the emoji in each emoji image. The size of the integrated emoji image ensures that all emoji images can be merged, and its size can be obtained by taking the power of 2 as the image size through the calculation result of the number of emoji images * EmojiSize * EmojiSize. The emoji attribute data is Texture_Emoji_JsonArray data, that is, json data, and the data result of json data can be defined according to the code of the sprite import tool of Unity's built-in text rendering component TextMesh Pro.

[0048] In the embodiment of the present invention, the emoticon atlas font may be generated in the following manner:

[0049] Prepare the sprite import tool of the text rendering component TextMesh Pro, put in the integrated emoticon image (Texture image) and emoticon attribute data (json data), and click Export sprite font to generate the corresponding emoticon atlas font file (Emoji sprite font).

[0050] In the embodiment of the present invention, the emoticon corresponding to the text data may be determined according to the text data input by the user, and then the font index label of the emoticon in the emoticon atlas font may be further determined.

[0051] Step 120: Determine an emoticon image to be rendered in the emoticon atlas font according to the font index tag, render the emoticon image to be rendered, and generate an emoticon corresponding to the text data.

[0052] Among them, the text rendering component TextMeshPro in Unity can be used to render the emoticon image to be rendered to generate the corresponding emoticon.

[0053] In an embodiment of the present invention, after determining the font index tag, the position of the emoticon image to be rendered in the emoticon atlas font can be determined according to the font index tag, so that the text rendering component can accurately render the emoticon and generate the emoticon corresponding to the text data.

[0055] The implementation of the embodiments of the present invention has the following beneficial effects:

[0056] The embodiment of the present application combines multiple emoticon images into an integrated emoticon image, and generates an emoticon atlas font in combination with emoticon attribute data, so that the emoticon atlas contains comprehensive emoticons, and is able to determine the corresponding emoticon image in the atlas font based on a variety of different text data input by the user, and generate emoticons through rendering, so that diversified emoticons can be generated according to user needs, effectively improving the generation effect of emoticons.

[0057] Figure 5 FIG. 2 is a flow chart showing another embodiment of the emoticon generation method of the present invention, wherein the method is executed by an emoticon generation device. Figure 5 As shown, the method comprises the following steps:

[0058] Step 510: traverse each character of the text data, and determine the emoticon code formed by the characters in the text data according to the Unicode code and the surrogate pair of the characters in the text data.

[0059] In an embodiment of the present invention, the text data may include multiple characters, and usually the Unicode encoding of two characters constitutes an emoticon encoding (emoji encoding). In Unicode encoding, a surrogate pair is composed of a high-order surrogate interval and a low-order surrogate interval, which are used to represent characters that cannot be represented by 16-bit Unicode, wherein the high-order surrogate interval is [0xD800, 0xDBFF] and the low-order surrogate interval is [0xDC00, 0xDFFF]. The embodiment of the present invention can determine the emoticon encoding constituted by the characters in the text data by judging the relationship between the Unicode encoding of the characters in the text data and the surrogate pair.

[0060] Step 520: Determine the font index tag corresponding to the emoticon in the emoticon atlas font according to the emoticon code, wherein the emoticon atlas font is generated according to an integrated emoticon image and emoticon attribute data, wherein the integrated emoticon image is obtained by merging multiple emoticon images, and the emoticon attribute data is generated based on the position information of each emoticon image in the integrated emoticon image.

[0061] In an embodiment of the present invention, text data includes strings and text fields, etc. In an embodiment of the present invention, an emoticon database can be imported to obtain multiple emoticon images in the emoticon database. The emoticon images in the emoticon database almost include all emoticons. Special emoticon images can be obtained and imported separately to improve the comprehensiveness of the integrated emoticon images, so that the emoticon collection fully includes emoticons that may be used. In an embodiment of the present invention, a python tool script can be used to convert the imported emoticon images into a preset size, such as a 32X32 image, and import it into a Unity project.

[0062] In an embodiment of the present invention, the emoji attribute data includes the position information of each emoji image in the integrated emoji image, and the unique emoji code corresponding to the emoji in each emoji image. The size of the integrated emoji image ensures that all emoji images can be merged, and its size can be obtained by taking the power of 2 as the image size through the calculation result of the number of emoji images * EmojiSize * EmojiSize. The emoji attribute data is Texture_Emoji_JsonArray data, that is, json data, and the data result of json data can be defined according to the code of the sprite import tool of Unity's built-in text rendering component TextMesh Pro.

[0063] In the embodiment of the present invention, the emoticon atlas font may be generated in the following manner:

[0064] Prepare the sprite import tool of the text rendering component TextMesh Pro, put in the integrated emoticon image (Texture image) and emoticon attribute data (json data), and click Export sprite font to generate the corresponding emoticon atlas font file (Emoji sprite font).

[0065] In the embodiment of the present invention, the emoticon corresponding to the text data may be determined according to the text data input by the user, and then the font index label of the emoticon in the emoticon atlas font may be further determined.

[0066] Step 530: Determine an emoticon image to be rendered in the emoticon atlas font according to the font index tag, render the emoticon image to be rendered, and generate an emoticon corresponding to the text data.

[0067] Among them, the text rendering component TextMeshPro in Unity can be used to render the emoticon image to be rendered to generate the corresponding emoticon.

[0068] In an embodiment of the present invention, after determining the font index tag, the position of the emoticon image to be rendered in the emoticon atlas font can be determined according to the font index tag, so that the text rendering component can accurately render the emoticon and generate the emoticon corresponding to the text data.

[0069] The embodiment of the present invention combines multiple emoticon images into an integrated emoticon image, and generates an emoticon atlas font in combination with emoticon attribute data, so that the emoticon atlas contains comprehensive emoticons, and can determine the corresponding emoticon image in the atlas font according to a variety of different text data input by the user, so as to generate diversified emoticons according to user needs, effectively improving the generation effect of emoticons; and through the font index tag, the emoticon image to be rendered can be quickly located, without the need to search and render each character separately, effectively improving the generation efficiency of emoticons.

[0070] In an optional manner, the surrogate pair includes a high surrogate interval and a low surrogate interval, and determining the emoticon encoding of the characters in the text data according to the Unicode encoding of the characters in the text data and the surrogate pair includes:

[0071] When the Unicode code of the current character is in the high surrogate interval and the Unicode code of the next character is in the low surrogate interval, the Unicode code of the current character and the Unicode code of the next character are determined as an emoticon code until all emoticon codes in the text data are determined.

[0072] In the embodiment of the present invention, the high-order surrogate interval is [0xD800, 0xDBFF], and the low-order surrogate interval is [0xDC00, 0xDFFF].

[0073] In an optional manner, the surrogate pair includes a high surrogate interval and a low surrogate interval, and determining the emoticon encoding of the characters in the text data according to the Unicode encoding of the characters in the text data and the surrogate pair further includes:

[0074] When the Unicode code of the current character is not in the high surrogate interval and the next character is a selection modifier or a connector, the Unicode code of the current character and the Unicode code of the next character are determined as an emoticon code until all emoticon codes in the text data are determined.

[0075] In the embodiment of the present invention, the modifier is selected as 0xfeof and the connector is selected as 0x200D. The embodiment of the present invention traverses the character string in the text data and compares each character with the surrogate pair and the special symbol code to determine all emoticon codes formed by the characters in the text data. All emoji codes in the text data may be single-encoding form emoji codes or multi-encoding form emoji codes. For example, a text data includes 6 character strings, the first character and the second character constitute the first emoji code, the third character and the fourth character constitute the second emoji code, and the fifth character and the sixth character constitute the third emoji code, wherein the first emoji code and other emoji codes cannot be combined into a multi-encoding form emoji code, that is, the first emoji code is a single-encoding form emoji code; the second emoji code and the third emoji code constitute a multi-encoding form emoji code, that is, the text data contains a single-encoding form emoji code and a multi-encoding form emoji code, and the integrated emoji image also includes emoji codes corresponding to single-encoding form emojis and multi-encoding form emojis. By determining all emoji codes in the text data, the font index label of the corresponding emoji in the emoji atlas font can be accurately determined according to the emoji codes.

[0076] In an optional manner, the determining, according to the emoji code, a font index tag corresponding to the emoji in the emoji atlas font further includes:

[0077] Determine the emoji corresponding to the emoji code in the emoji atlas font, and obtain the index of the emoji;

[0078] A font index tag for the emoji is generated based on the index.

[0079] In an embodiment of the present invention, the emoji atlas font includes emoji attribute data, wherein the emoji attribute data includes an emoji code corresponding to each emoji, and the emoji code of the text data is searched in the emoji atlas font to determine whether it exists. If so, the index index of the emoji code is obtained and converted into a font index tag.<sprite=index> , so that the text rendering component TextMeshPro can search for the corresponding emoji image in the emoji atlas according to the font index tag when rendering, so that the emoji can be rendered according to the correlation between the emoji code and the emoji atlas.

[0080] The embodiment of the present invention determines the emoticon corresponding to the emoticon encoding in the emoticon atlas font and obtains the index of the emoticon to generate a font index tag. It can quickly find the emoticon based on the font index tag, and can quickly and accurately generate the corresponding emoticon according to the text data input by the user, effectively improving the generation effect of the emoticon.

[0081] In an optional manner, after generating the emoji atlas font, the method further includes:

[0082] The emoji atlas font is updated according to the acquired backup atlas font.

[0083] In an embodiment of the present invention, the backup atlas font can be a fallback font, and the emoji atlas sub-image can be an Emoji sprite font. In an embodiment of the present invention, the dynamically added backup atlas font can be added to the emoji atlas font. When the text data entered by the user cannot be displayed due to some reasons (such as the font file failed to load, the font does not support certain characters, etc.), the fallback font can ensure that the text content can still be read; the fallback font can specify different fonts for different character sets to ensure that all texts can be displayed correctly, thereby ensuring that text content in different languages ​​can be displayed normally. When the user enters text data, TextMeshPro will automatically search for text data that conforms to the encoding in the updated emoji atlas font.

[0084] In an optional manner, determining the emoji image to be rendered in the emoji atlas font according to the font index tag includes:

[0085] Determine the position information of the emoticon image corresponding to the font index tag in the emoticon atlas font;

[0086] The emoticon image corresponding to the position information is determined as the emoticon image to be rendered.

[0087] In the embodiment of the present invention, by determining the accurate position information of the emoticon image, it can be ensured that the required emoticon can be found quickly and accurately during the rendering process, which can effectively improve the efficiency and accuracy of the rendering.

[0088] In an optional manner, during the emoji generation process, asynchronous loading and caching technology is used to effectively reduce the time for loading emojis and related image resources, thereby effectively improving the response time for generating emojis, and further effectively improving the efficiency of emoji generation.

[0089] In an alternative approach, Figure 6 FIG. 2 shows a flow chart of a text character processing process according to an embodiment of the present invention. Figure 6 As shown, after inputting text data, the text data is decoded into Unicode characters, and the emoji atlas font is queried based on the decoded characters to see whether there is a corresponding emoji. If so, it is added as a sprite tag, and the text data is continued to be decoded into Unicode characters; if not, the current character is added as ordinary text, so that the final displayed content can include emojis and / or ordinary text.

[0090] In the embodiment of the present invention, for text data in a specific encoding format, the decoding speed and decoding accuracy can be improved by optimizing the encoder. For example, for text data encoded in UTF-8, a more efficient decoding algorithm can be used.

[0091] In an optional approach, a third-party library may be used to process the mixing of images and text and to render emojis, so as to solve common performance and compatibility issues and improve the reliability of emoji generation.

[0092] In an alternative approach, Figure 7 A schematic diagram of a process for generating an atlas font file is shown in FIG. Figure 7 As shown, the process of generating atlas font files includes:

[0093] Step 710: Obtain multiple emoji images from the emoji-data image library;

[0094] Step 720: using a python tool to convert multiple emoticon images into images of uniform resolution;

[0095] Step 730: Import the uniform resolution image into Unity, and generate the intermediate atlas and atlas information record file required by TextMeshPro through a custom tool;

[0096] In the embodiment of the present invention, TextMeshPro is a text rendering component in Unity. Among them, the intermediate atlas and the atlas information record file are both json files, and the intermediate atlas and the atlas information record file work together to optimize the storage and rendering of sprites. The intermediate atlas can be an integrated picture obtained by integrating multiple emoticon pictures of uniform resolution. The atlas information record file includes the attribute information of the emoticon picture, including the position information of the emoticon in the intermediate atlas, and the emoticon code corresponding to each emoticon.

[0097] Step 740: Use the Sprite lmport tool to import the intermediate atlas into the TMP Sprite Asset; wherein, TMP Sprite Asset is a core component in the Unity TextMesh Pro plug-in, which is used to manage and reference sprites resources.

[0098] Step 750: Generate atlas font files.
