[0042] Many specific details are described in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

[0043] It should be noted that the terms "first", "second", "third", etc. in the claims, description and drawings of the present application are used to distinguish similar objects and are not used to describe a specific order or sequence. The data used in this way are interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including", "having" and their variants are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0044] It should be understood that in the embodiments of the present application, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" is merely a way to describe the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship. "Including A, B and / or C" means including any one, any two, or any three of A, B, and C.

[0045] It should be understood that in the embodiments of the present application, "B corresponding to A", "B corresponding to A", "A corresponds to B", or "B corresponds to A" means that B is associated with A, and B can be determined according to A. Determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.

[0046] In game development, you can achieve diversified font effects in text based on Unreal Engine (UE). In UE, each line of text is regarded as a UV sampling range of 0 to 1, and the font texture is sampled with the UV range of 0 to 1, and the sampled font texture is rendered and displayed.

[0047] However, when the text content is long or contains multiple lines, the font texture will be stretched or compressed, resulting in unclear font display and affecting image quality.

[0048] Among them, Unreal Engine is a powerful game engine developed by Epic Games, which is widely used in game development, virtual reality (VR), augmented reality (AR) and other simulation environments. It provides developers with multiple functions such as graphics rendering, physical simulation, network communication, etc., allowing developers to create complex interactive scenes and high-quality three-dimensional (3D) graphics.

[0049] Font rendering refers to the process of converting text characters into graphic images, which can also be understood as representing text characters with pixels. For computer graphics, font rendering involves extracting the shape of the characters from the font file and drawing them to the screen or other output device, usually considering the font's size, color, spacing and other properties. UV coordinates are a two-dimensional coordinate system that is commonly used in computer graphics, especially in texture mapping of three-dimensional models. The U and V coordinates define a point on a two-dimensional texture image. The U coordinate represents the coordinate value in the horizontal direction, usually between 0 and 1 (or depending on the resolution of the texture image, it may exceed this range, but it will be normalized). The V coordinate represents the coordinate value in the vertical direction, also usually between 0 and 1.

[0050] In the prior art, when using the UV sampling image of the text provided by the UE, each line of text is usually sampled as an independent UV range, which means that for each line of text, the UE will map it to a UV range of 0 to 1. However, since the length and height of the text vary, the increase in text length and number of lines will increase the risk of texture deformation, especially in multi-line text, where the distribution of each line may be different. When they are forced to be mapped to the same UV range, stretching or compression will occur. As a result, after the text characters are converted into an image, the resolution is shared when long text or multi-line text is displayed, and the image is not clear, affecting the user's perception. The resolution refers to the number of pixels per unit area of ​​the image. A higher resolution means that the image can display more details.

[0051] Figure 1 A schematic diagram of an image obtained by sampling each line of text as an independent UV range provided in an embodiment of the present application. Figure 1 In the image, each line of text is sampled as a UV range of 0 to 1. Therefore, the image is stretched and compressed by the text range, making it unclear.

[0052] Based on background technical reasons, in order to improve the clarity of the image after converting text characters into an image and enhance the user experience. The first embodiment of the present application provides a data processing method, which is applied to an electronic device, which can be a desktop computer, a laptop computer, a mobile phone, a tablet computer, an electronic watch, etc., or other electronic devices capable of data processing, which is not specifically limited in the embodiments of the present application.

[0053] The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0054] Figure 2 The following is a flow chart of a data processing method provided in an embodiment of the present application. Figure 2 As shown, the data processing method may include S201-S205.

[0055] S201, obtaining a character segment to be processed and a preset texture map.

[0056] For example, the encoding file corresponding to the character segment to be processed can be obtained first, the encoding file of the text to be processed can be decomposed into individual characters, and each character can be parsed to obtain the character segment to be processed. The texture map provided by the artist can also be obtained.

[0057] S202: Determine first position information of each character in the character segment to be processed, where the first position information is used to represent the pixel coordinates of the character in the character segment to be processed.

[0058] In an optional embodiment, S202 may be implemented through S301 - S303 .

[0059] S301, selecting a font file, and obtaining the attribute of each character in the character segment to be processed from the font file;

[0060] Exemplarily, a font file can be selected, such as a TrueType font (TTF), an OpenType font (OTF), etc., and the attributes of each character in the character segment to be processed can be determined based on the font file. The attributes of the characters may include the area occupied by each character in the character segment to be processed, the position of the area occupied by each character in the character segment to be processed, the width and height of each character, character spacing, line spacing, line height and line width of each line of characters, etc. Among them, TTF is a widely used font format developed by Apple. It is composed of curves and straight lines defined by mathematical formulas, and each glyph of the font is defined using mathematical curves, so they can be scaled to any size without distortion. This font format allows font designers to precisely control the placement of each pixel, especially at low resolutions, so that it can remain clear at different resolutions, making the text more readable on the screen. TTF font files usually contain all the necessary information of the font for rendering by the system or application. OTF is a font format developed by Microsoft and Adobe. It is an extension of TrueType fonts and supports a wide range of character sets, including characters and symbols in multiple languages. It also supports more advanced font features, such as contextual alternates, ligatures, character spacing adjustment, etc. OTF can also contain glyph information of PostScript fonts, so it has better cross-platform compatibility and can run seamlessly on operating systems such as Windows, macOS, and Linux. In addition, OpenType fonts also support font embedding technology, which means that they can be embedded in documents or applications to ensure that they can be displayed correctly on different computers or devices. Character spacing refers to the horizontal space between two adjacent characters. Line spacing refers to the vertical space between two lines of characters. It is usually determined based on the size of the characters and the line height. Too small line spacing may cause characters to overlap each other, and too large line spacing may affect the coherence of the character segment. Character width and height indicate the space occupied by a single character in the character segment to be processed on the screen. The width of the character refers to the horizontal size of the character, while the height of the character refers to the vertical size of the character.

[0061] S302, determining a bounding box of the character segment to be processed according to the attributes of the character;

[0062] S303: Determine the position information of the bounding box of the character in the to-be-processed character segment, and use the position information of the bounding box of the character in the to-be-processed character segment as the first position information.

[0063] Exemplarily, the character segment to be processed is regarded as a whole, and the bounding box of the character segment to be processed is determined according to the attributes of each character mentioned above. The bounding box of the character segment to be processed is a rectangular area, which describes the minimum outer size of the character segment to be processed. In font rendering, the bounding box represents the outer boundary of a character segment or a single character, which is used to determine the position and size of the character on the screen or in a virtual space. The width of the bounding box of the character segment to be processed is the maximum width of all character rows, and the height of the bounding box of the character segment to be processed is the sum of the accumulated values ​​of the row heights of all character rows and the spacing between each row. Among them, the bounding box of the character segment to be processed also includes additional space. For example, when determining the bounding box of the character segment to be processed, if a picture is inserted into a row of characters, and the height of the picture is greater than the height of the character row in which it is located, then the row height of the character row where the picture is located is at least the height of the picture.

[0064] For example, Figure 3 Schematic diagram of the bounding box of the character segment to be processed provided in the embodiment of the present application. Figure 3 As shown, the width of the bounding box is x, and the height of the bounding box is (y+y+z). The width of the bounding box of the character segment to be processed, the height of the bounding box of the character segment to be processed, and the coordinates of the upper left corner and the lower right corner of the bounding box of the character segment to be processed in the pixel coordinate system can be stored in uv[3], where uv[3] is a two-dimensional vector. The coordinates of the upper left corner of the bounding box can be used as the origin to determine the coordinates of each character in the bounding box of the character segment to be processed, and the coordinates of each character in the bounding box of the character segment to be processed can be used as the first position information.

[0065] S203. Normalize the first position information to obtain second position information of each character in the character segment to be processed, where the second position information is used to represent the normalized coordinates of the character in the character segment to be processed.

[0066] Exemplarily, after determining the first position information of each character in the character segment to be processed, the first position information of each character in the character segment to be processed can be normalized to obtain the second position information of each character in the character segment to be processed, that is, the normalized coordinates of the character in the character segment to be processed, and the normalized coordinates of the character in the character segment to be processed are stored in the font's uv[0], where uv[0] is a two-dimensional vector. For example, assuming that the character segment to be processed is "HELO", the first position information of "H" is 1, the first position information of "E" is 2, the first position information of "L" is 3, and the first position information of "O" is 4, the first position of the character is normalized, and it can be determined that the length of the character segment is 4, the second position information of "H" is 1 / 4=0.25, the second position information of "E" is 2 / 4=0.5, the second position information of "L" is 3 / 4=0.75, and the second position information of "O" is 4 / 4=1.0.

[0067] S204: Sampling in the texture map according to the second position information to obtain color information corresponding to each character.

[0068] S205 , rendering and displaying the character segment to be processed according to the color information corresponding to each character.

[0069] Exemplarily, the texture map provided by the artist contains multiple character textures. On this map, each character occupies a specific area, and each area has its own UV coordinate range. After the second position information of each character is determined, each character can be mapped on the texture map, that is, the UV coordinate range of each character on the texture map is determined, and the rendering engine can draw the character's glyph on the screen according to the first position information of each character, and at the same time, sample the texture map according to the UV coordinate of each character on the texture map, that is, extract the color information of each character, and apply the sampled color information to the pixels of the image corresponding to the character, so as to present an image of the character with rich details on the screen. The above color information may include RGBA parameters. RGBA is a color model that represents the color information of four channels: red, green, blue, and alpha. In computer graphics, image processing, and web design, the RGBA color model is widely used because it can accurately describe colors and the transparency of colors. The red channel (red, R) represents the red component of the color, and its value range is usually 0 to 255 (at 8-bit color depth), with 0 representing no red and 255 representing the strongest red. The green channel (green, G) represents the green component of the color, and its value range is also 0 to 255. 0 represents no green and 255 represents the strongest green. The blue channel (blue, B) represents the blue component of the color, and its value range is also 0 to 255. 0 represents no blue and 255 represents the strongest blue. The transparency channel (alpha, A) represents the transparency of the color, and its value range is also 0 to 255 (in some cases it may be a floating point number from 0 to 1), with 0 representing completely transparent and 255 representing completely opaque. The RGBA color model allows you to create and represent almost any color by adjusting the values ​​of these four channels, including pure colors, gradients, and colors with transparency. For example, an RGBA value for pure red might be (255, 0, 0, 255), representing the strongest red, no green and blue, and completely opaque. A semi-transparent red value might be (255, 0, 0, 128), which means the strongest red, no green and blue, but 50% transparency (assuming 25 is completely opaque). In image processing software, the RGBA color model is also commonly used to edit the transparency and color of images. By adjusting the values ​​of each channel, users can create complex visual effects such as shadows, highlights, gradients, and semi-transparency.

[0070] In an optional embodiment, S303 may be implemented through S401 - S402 .

[0071] S401, determining a bounding box of the character according to the attributes of the character;

[0072] S402 determines the position information of the bounding box of the character in the bounding box of the character segment to be processed, and uses the position information of the bounding box of the character in the bounding box of the character segment to be processed as the position information of the bounding box of the character in the character segment to be processed.

[0073] Exemplarily, the attributes of the characters are obtained through the font file, and the attributes of the characters may include the size of the characters, the spacing between characters, the baseline offset of the characters, etc. According to the attributes of the characters, the bounding box of the characters may be determined, and the bounding box of the characters describes the minimum external dimensions of the characters. Among them, the baseline offset of the character refers to the part of the character that exceeds the baseline, and the bounding box of the character includes the baseline offset of the glyph. For example, when the character is a Chinese character, the bounding box of the character describes the minimum external dimensions of the Chinese character, which is usually a square. When the character is a lowercase English letter, some of the strokes of the lowercase English letters will exceed the baseline. The part that exceeds the baseline can be understood as the baseline offset of the character. When determining the bounding box of the character, the baseline offset of the character must be taken into account to ensure that the bounding box of the character completely frames the character in the bounding box, that is, to ensure that the bounding box of the character describes the minimum external dimensions of the character. Figure 4 The baseline offset diagram when the characters provided in the embodiment of the present application are English letters. Figure 4 As shown, the character segment to be processed includes the characters "abcdefg", and line 1 and line 2 can be understood as the baselines of the characters, wherein some strokes of the character "bdf" exceed line 1, and some strokes of the character "g" exceed line 2, so when determining the bounding box of the character "bdfg", the baseline offset of the character "bdfg" needs to be taken into account.

[0074] In an optional embodiment, the above method may further include S501-S502.

[0075] S501, determining the upper left corner coordinates and the lower right corner coordinates of the bounding box of the character and the upper left corner coordinates and the lower right corner coordinates of the bounding box of the character segment to be processed;

[0076] S502: Determine the position information of the bounding box of the character in the bounding box of the character segment to be processed according to the upper left corner coordinates and the lower right corner coordinates of the bounding box of the character and the upper left corner coordinates and the lower right corner coordinates of the bounding box of the character segment to be processed.

[0077] Exemplarily, the upper left pixel coordinates of the bounding box of the character segment to be processed can be used as the origin, and the width and height of the character segment to be processed can be used to determine the lower right pixel coordinates of the bounding box of the character segment to be processed. After the bounding box of each character in the character segment to be processed is determined, the upper left pixel coordinates and lower right pixel coordinates of the bounding box of each character can be determined based on the upper left pixel coordinates, lower right pixel coordinates, and the size of the bounding box of each character. The position information of the bounding box of the character in the bounding box of the character segment to be processed can be obtained through the upper left pixel coordinates and lower right pixel coordinates of the bounding box of each character.

[0078] In an optional embodiment, the above-mentioned normalization processing of the first position information to obtain the second position information of each character in the character segment to be processed may include: normalizing the first position information according to the ratio of the horizontal coordinate of the upper left corner coordinate of the character's bounding box to the width of the bounding box of the character segment to be processed, the ratio of the vertical coordinate of the upper left corner coordinate of the character's bounding box to the height of the bounding box of the character segment to be processed, the ratio of the horizontal coordinate of the lower right corner coordinate of the character's bounding box to the width of the bounding box of the character segment to be processed, and the ratio of the vertical coordinate of the lower right corner coordinate of the character's bounding box to the height of the bounding box of the character segment to be processed, so as to obtain the second position information of each character in the character segment to be processed.

[0079] Exemplarily, after determining the pixel coordinates of the upper left corner and the lower right corner of the bounding box of each character in the character segment to be processed, the first position information of each character in the character segment to be processed can be normalized by calculating the ratio of the horizontal coordinate of the pixel coordinates of the upper left corner of the character's bounding box to the width of the bounding box of the character segment to be processed, the ratio of the vertical coordinate of the pixel coordinates of the upper left corner of the character's bounding box to the height of the bounding box of the character segment to be processed, the ratio of the horizontal coordinate of the pixel coordinates of the lower right corner of the character's bounding box to the width of the bounding box of the character segment to be processed, and the ratio of the vertical coordinate of the pixel coordinates of the lower right corner of the character's bounding box to the height of the bounding box of the character segment to be processed, so as to obtain the second position information of each character in the character segment to be processed.

[0080] For example, in a character segment to be processed, the coordinates of the rectangular area occupied by the image of a character Q in the pixel coordinate system can be expressed as: (x min, y min), (x max, y max), where (x min, y min) represents the upper left pixel coordinates of the rectangular area occupied by the character, that is, the upper left pixel coordinates of the bounding box of the character, and (x_max, y_max) represents the lower right pixel coordinates of the rectangular area occupied by the character, that is, the lower right pixel coordinates of the bounding box of the character. Assuming that the total width of the bounding box of the character segment to be processed is W and the total height is H, the UV coordinates of each character in the bounding box of the character segment to be processed can be calculated by formula (1).

[0081] u min=x_min / W; v_min=y_min / H; u_max=x_max / W; v_max=y_max / H

[0082] Formula (1)

[0083] Among them, (u_min, v_min) is the normalized coordinate of the upper left corner of the rectangular area occupied by the character Q, that is, the normalized coordinate of the upper left corner of the bounding box of the character Q, and (u_max, v_max) is the normalized coordinate of the lower right corner of the rectangular area occupied by the character Q, that is, the normalized coordinate of the lower right corner of the bounding box of the character Q.

[0084] In an optional embodiment, the above S204 can be implemented through S501-S502.

[0085] S501 : Determine a ratio of a width of a bounding box of the to-be-processed character segment to a width of the preset texture map and a ratio of a height of a bounding box of the to-be-processed character segment to a height of the preset texture map.

[0086] S502. Map the second position information to the preset texture map according to the ratio of the width of the bounding box of the character segment to be processed to the width of the preset texture map and the ratio of the height of the bounding box of the character segment to be processed to the height of the preset texture map to obtain the color information of the character segment to be processed.

[0087] Exemplarily, the width and height of the texture map provided by the artist can be obtained, and by determining the ratio of the width of the bounding box of the character segment to be processed to the width of the preset texture map, and the ratio of the bounding box height of the character segment to be processed to the height of the preset texture map, the second position information of each character in the character segment to be processed is mapped to the preset texture map to obtain the color information of the character segment to be processed. Exemplarily, the second position information of each character in the character segment to be processed can be mapped to the preset texture map according to formula (2), and the texture map is sampled according to the UV coordinates of each character to obtain the color information corresponding to each character.

[0088] uvs = uv[0] * float2(uv[3].x / tw, uv[3].y / th) Formula (2)

[0089] Wherein, uv[0] represents the normalized coordinates of each character in the character segment to be processed, uv[3].x represents the width of the bounding box of the character segment to be processed, uv[3].y represents the height of the bounding box of the character segment to be processed, tw represents the width of the preset texture map, and th represents the height of the preset texture map. uvs can represent the UV coordinates corresponding to each character in the character segment to be processed in the preset texture map. According to the UV coordinates corresponding to each character in the character segment to be processed in the preset texture map, the color information of each character in the character segment to be processed can be sampled, such as the RGBA value of each character in the character segment to be processed, and each character in the character segment to be processed is rendered and displayed according to the color information of each character in the character segment to be processed.

[0090] In an optional embodiment, the above-mentioned parsing of the encoding file corresponding to the character segment to be processed to obtain the character segment to be processed may include: parsing the encoding file corresponding to the character segment to be processed according to the escape characters in the encoding file corresponding to the character segment to be processed to obtain the character segment to be processed.

[0091] Exemplarily, escape characters may include line breaks and tabs. The encoded file of the text to be processed is decomposed into individual characters. When each character is parsed, when an escape character is identified, the encoded file of the text to be processed can be processed according to the specific meaning of the escape character. For example, when the encoded file of the character segment to be processed includes line breaks (\n) and tabs (\t), the line break can be identified, the characters after the line break are arranged in a new line, and the line break is deleted. The tab character represents a horizontal tab position, which is usually used to indent or align text. During parsing, the tab character can be identified and the subsequent characters can be horizontally offset to align according to the typesetting rules, and the tab character can be deleted.

[0092] The above is a specific implementation of data processing. In the specific implementation, the model can also be trained in other feasible ways, and the embodiments of the present application are not limited thereto.
