[0096] Embodiment 1

[0097] See also Figure 1 , Figure 1 1 is a flow chart of a font adjustment method for cross-platform text display disclosed in an embodiment of the present invention. Figure 1 The described font adjustment method for cross-platform text display may be developed in the Flutter framework, and the method may be applied to a font adjustment device for cross-platform text display, wherein the device may include a font adjustment device or a font adjustment server, wherein the font adjustment server may include a cloud server or a local server, which is not limited in the embodiments of the present invention. Figure 1 As shown, the font adjustment method for cross-platform text display may include the following operations:

[0098] 101. Obtain text content input by the user on the target platform, and read character information of the text content.

[0099] In the embodiment of the present invention, optionally, the character information includes a character type and the number of characters of the corresponding character type. The character type may include a combination of one or more letter types, number types, punctuation types, and special symbol types, which are not limited in the embodiment of the present invention.

[0100] 102. Determine the text length of the text content in the target font according to the character information and the determined target font to be displayed.

[0101] In the embodiment of the present invention, the text length refers to the width (or height) occupied by the text content when it is actually displayed under the condition of the target font and the determined initial font size of the text content based on the target font.

[0102] 103. Determine a target font size of the text content according to the determined text content based on the initial font size of the target font and the text length.

[0103] In an embodiment of the present invention, optionally, it is possible to determine whether the text content overflows the text display device based on the initial font size and the text length, obtain a determination result, and adjust the initial font size based on the determination result to obtain a target font size; further optionally, it is possible to predict the space occupied by the text content on the text display device based on the initial font size and the text length, and compare the predicted occupied space with the space that can be displayed by the text display device to obtain a comparison result, and then determine the adjustment requirement for the initial font size based on the comparison result, and determine the target font size based on the adjustment requirement.

[0104] 104. Render the text content to a text display device of the target platform according to the target font size, so that the text display device displays the text content.

[0105] It can be seen that implementation Figure 1The font adjustment method for cross-platform text display described can obtain the text content input by the user on the target platform, read the character information of the text content, and determine the text length of the text content under the target font based on the character information and the determined target font to be displayed, which can improve the accuracy and efficiency of determining the text length of the text content. Subsequently, the target font size of the text content is determined based on the determined text content based on the initial font size and text length of the target font, which can improve the accuracy and efficiency of determining the target font size of the text content. It can improve the adjustment accuracy and efficiency of the text font when displaying text across platforms, which is conducive to realizing intelligent adjustment of the text font. Then, according to the target font size, the text content is rendered to the text display device of the target platform so that the text display device displays the text content. The rendering accuracy of the text content to the text display device can be improved based on the accurately adjusted text font, which is conducive to improving the display integrity of the text content, thereby helping to improve the user experience.

[0106] In an optional embodiment, the above step 102 of determining the text length of the text content in the target font according to the character information and the predetermined target font to be displayed may include:

[0107] Determine, according to a predetermined target font to be displayed, a character spacing between each character in all characters corresponding to the character information in the target font;

[0108] According to the character information, all characters corresponding to the character information are grouped to obtain multiple character groups, and all characters in the same character group correspond to the same character type;

[0109] According to the target font and each character type, determining the character length of each character in the character group corresponding to the character type under the target font;

[0110] For each character group, according to the number of characters in the character group and the character length of each character in the character group, the sum of the character lengths of the character group is calculated;

[0111] According to the character spacing between each character in all characters and the sum of the character lengths of each character group in all character groups, the overall character length of all characters is calculated as the text length of the text content in the target font.

[0112] In the embodiment of the present invention, specifically, calculating the total character length of all characters as the text length of the text content in the target font according to the character spacing between each character in all characters and the sum of the character lengths of each character group in all character groups may include:

[0113] According to the text content, character sorting information of the text content is determined; according to the character sorting information, a target character spacing matching the character sorting information is screened out from the character spacing between each character in all characters;

[0114] The sum of the character lengths of each character group in all character groups and the sum of all target character spacings are calculated to obtain the overall character length of all characters as the text length of the text content in the target font. The target character spacing that matches the character sorting information may include the character spacing between the adjacent preceding characters and the adjacent following characters.

[0115] It can be seen that this optional embodiment can determine the character spacing between each character in all characters corresponding to the character information under the target font according to the predetermined target font to be displayed, which can improve the determination accuracy and efficiency of the character spacing between each character under the target font, and group all characters corresponding to the character information according to the character information to obtain multiple character groups, which can improve the grouping accuracy of the character information, and determine the character length of each character in the character group corresponding to the character type under the target font according to the target font and each character type, which can improve the determination accuracy and efficiency of the character length of each character of each character type under the target font, and then for each character group, calculate the sum of the character lengths of the character group according to the number of characters in the character group and the character length of each character in the character group, and calculate the overall character length of all characters according to the character spacing between each character in all characters and the sum of the character lengths of each character group in all character groups as the text length of the text content under the target font, which can improve the calculation accuracy and reliability of the text length of the text content based on the character spacing between each character and the character length of each type of character.

[0116] In another optional embodiment, the method may further include:

[0117] Get the platform characteristics of the target platform;

[0118] According to the platform characteristics of the target platform, a matching font is selected from a font database that can be displayed by the text display device as the target font to be displayed.

[0119] In an embodiment of the present invention, optionally, the platform characteristics of the target platform may include one or more combinations of the operating system of the target platform, the device characteristics of the text display device of the target platform, and the font rendering engine information of the target platform (such as Core Text, FreeType, DirectWrite, etc.). Among them, the operating system may be one of iOS, Android, Web, etc., and the operating systems of different types of platforms have different font rendering mechanisms and font libraries. For example, iOS and Android may use different system fonts (such as "San Francisco" for iOS and "Roboto" for Android) to ensure cross-platform consistency and localized experience. The device characteristics of the text display device may include one or more combinations of the resolution of the text display device, the screen size of the text display device, and the pixel density (DPI) of the text display device. According to the display characteristics of the text display device (such as resolution and DPI), appropriate font weight (thickness) and style (regular, italic, etc.) can be selected to optimize the readability of the text. For example, on a high DPI device, the font needs to be appropriately enlarged to ensure clear readability; on a low DPI device, a thinner font or a larger line spacing is required to prevent blur or overlap of characters. The character rendering engine information may include the anti-aliasing, sub-pixel rendering, and font smoothing processing methods of the character rendering engine. Among them, the anti-aliasing processing method can enable or optimize anti-aliasing on devices that support anti-aliasing to reduce the jagged effect of the font edge and make the font smoother; the sub-pixel rendering processing method can use sub-pixel rendering technology on display devices such as LCDs to improve the clarity and readability of text; the font smoothing processing method can adjust the font smoothing level as needed on certain platforms to obtain the best display effect, and the implementation of the present invention is not limited thereto.

[0120] It can be seen that this optional embodiment can obtain the platform characteristics of the target platform, and according to the platform characteristics of the target platform, select a matching font from the font database that can be displayed by the text display device as the target font to be displayed, which can improve the selection accuracy and selection efficiency of the target font, and is conducive to the accurate selection of suitable fonts based on platform characteristics in the case of cross-platform text display.

The calculation formula for the font size to be adjusted is as follows:

[0133] Adjusted Font Size=Container Width / Text Length;

[0134] Among them, Adjusted Font Size is used to indicate the font size that needs to be adjusted, Container Width is used to indicate the display width of the text display device, and Text Length is used to indicate the text length.

[0135] 207. Re-determine whether the text content meets a preset text overflow condition based on the candidate font size, text length, and display area information to obtain a second determination result.

[0136] In the embodiment of the present invention, for other descriptions of step 207, please refer to the detailed description of step 204, and the embodiment of the present invention will not be repeated.

[0137] In the embodiment of the present invention, when the second judgment result of step 207 is yes, step 208 is triggered to be executed; when the second judgment result of step 207 is no, step 209 is triggered to be executed.

[0138] 208. Reduce the candidate font size by 1.

[0139] In an embodiment of the present invention, after step 208, the execution of step 207 is triggered to re-judge whether the text content meets the preset text overflow condition based on the candidate font size, text length and display area information to obtain the second judgment result until the second judgment result is no.

[0140] 209. Determine the candidate font size when the second judgment result is no as the target font size.

[0141] 210. Render the text content to a text display device of the target platform according to the target font size, so that the text display device displays the text content.

[0143] It can be seen that implementation Figure 2The font adjustment method for cross-platform text display described can obtain the text content input by the user on the target platform, read the character information of the text content, and determine the text length of the text content under the target font based on the character information and the determined target font to be displayed, which can improve the accuracy and efficiency of determining the text length of the text content. Subsequently, the target font size of the text content is determined based on the determined text content based on the initial font size and text length of the target font, which can improve the accuracy and efficiency of determining the target font size of the text content. It can improve the adjustment accuracy and efficiency of the text font when displaying text across platforms, which is conducive to realizing intelligent adjustment of the text font. Then, according to the target font size, the text content is rendered to the text display device of the target platform so that the text display device displays the text content. The rendering accuracy of the text content to the text display device can be improved based on the accurately adjusted text font, which is conducive to improving the display integrity of the text content, thereby helping to improve the user experience. In addition, it is also possible to obtain the display area information of the text display device, and determine whether the text content meets the preset text overflow condition based on the determined initial font size, text length and display area information of the text content, and obtain a first judgment result. It is possible to improve the judgment accuracy and efficiency of whether the text content meets the text overflow condition based on the initial font size, text length and display area information. When the first judgment result is no, the initial font size is determined as the target font size of the text content, which can improve the determination speed and efficiency of the target font size when the text does not overflow. When the first judgment result is yes, the candidate font size of the text content is determined based on the display area information and the text length, which improves the determination accuracy and reliability of the candidate font size. Subsequently, based on the candidate font size, text length and display area information, it is re-determined whether the text content meets the preset text overflow condition to obtain a second judgment result. When the second judgment result is yes, the candidate font size is reduced by 1, and the operation of re-determining whether the text content meets the preset text overflow condition to obtain the second judgment result based on the candidate font size, text length and display area information is triggered until the second judgment result is no, and the candidate font size when the second judgment result is no is determined as the target font size. This can improve the accuracy and efficiency of font size adjustment based on the display area information and text length when the text overflows, and the accuracy and reliability of the font size finally determined can be improved by repeated judgment of the adjusted font size.

[0144] In an optional embodiment, the above step 204 determines whether the text content meets a preset text overflow condition based on the determined initial font size of the text content and the display area information to obtain a first determination result, which may include:

[0145] Predicting the space required for displaying the text content in a text display device according to the determined initial font size of the text content and the display area information, where the space required for the text content includes a required width of the text and / or a required height of the text;

[0146] Determine whether the required width of the text is greater than the display width in the display area information, which is recorded as the first condition; or,

[0147] Determine whether the required height of the text is greater than the display height in the display area information, which is recorded as the second condition;

[0148] When at least one of the first condition and the second condition is satisfied, it is determined that the text content satisfies the text overflow condition, and the first judgment result is determined to be yes.

[0149] In an embodiment of the present invention, specifically, in a case where the text overflow condition only includes a first condition of whether the required width of the text is greater than the display width in the display area information, when the first condition is not met, it is determined that the text content does not meet the text overflow condition, and the first judgment result is determined to be no; in a case where the text overflow condition only includes a second condition of whether the required height of the text is greater than the display height in the display area information, when the second condition is not met, it is determined that the text content does not meet the text overflow condition, and the first judgment result is determined to be no.

[0150] In an embodiment of the present invention, specifically, when both the first condition and the second condition are not met, and when the display area information also includes the remaining displayable space of the text display device, the first spatial area of ​​the remaining displayable space of the text display device is calculated, and the second spatial area of ​​the space required for displaying the text content in the text display device is calculated, and the second spatial area is divided by the first spatial area to obtain the area ratio of the second spatial area to the first spatial area, and it is determined whether the area ratio is greater than 1, which is recorded as the third condition; wherein, when the third condition is met, it is determined that the text content meets the text overflow condition, and the first judgment result is determined to be yes; when the third condition is not met, it is determined that the text content does not meet the text overflow condition, and the first judgment result is determined to be no.

[0151] In an embodiment of the present invention, specifically, the execution priority of the first condition and the execution priority of the second condition are both greater than the execution priority of the third condition. This can improve the speed and efficiency of determining whether the text content satisfies the text overflow condition based on the first condition and / or the second condition, and can improve the accuracy and reliability of determining whether the text content does not satisfy the text overflow condition based on the third condition.

[0152] It can be seen that this optional embodiment can predict the space required for the text content when it is displayed in the text display device (the space required for the text content includes the required width of the text and / or the required height of the text) based on the determined initial font size of the text content and the display area information, and can improve the prediction accuracy and prediction efficiency of the space required for the text content, and judge whether the required width of the text is greater than the display width in the display area information, which is recorded as the first condition; or, judge whether the required height of the text is greater than the display height in the display area information, which is recorded as the second condition; and when at least one of the first condition and the second condition is met, it is determined that the text content meets the text overflow condition, and the first judgment result is determined to be yes, which can improve the accuracy and reliability of the judgment of whether the text content meets the text overflow condition, and by providing multiple conditions, the flexibility and diversity of the judgment of whether the text content meets the text overflow condition can be improved.

[0153] In another optional embodiment, the method may further include:

[0154] Determine an initial font size of the text content based on the target font according to the display height in the display area information and the predetermined expected number of text lines;

[0155] The initial font size of the text content based on the target font is determined according to the display height in the display area information and the predetermined expected number of text lines, including:

[0156] When the predetermined expected number of text lines is greater than 1, the font size required for the text content is calculated according to the display height in the display area information, the expected number of text lines, and the predetermined default line spacing ratio of the target font;

[0157] According to the font size required by the text content, one of the font sizes with the smallest difference from the font size required by the text content is selected from a predetermined font size database as the initial font size of the text content based on the target font.

[0158] In the embodiment of the present invention, specifically, the calculation formula for the font size required for the text content is as follows:

[0159] The font size required for text content = display height / (expected number of text lines * default line spacing ratio).

[0160] For example, assuming that the calculated font size required for the text content is 10.4, and the font size database contains font sizes including 8, 9, 10, 10.5, 11, and 12, then the font size 10.5 with the smallest difference from 10.4 is determined as the initial font size of the text content based on the target font.

[0161] It can be seen that this optional embodiment can calculate the font size required for the text content based on the display height in the display area information, the expected number of text lines and the predetermined default line spacing ratio of the target font when the predetermined expected number of text lines is greater than 1, thereby improving the calculation accuracy and efficiency of the font size required for the text content. According to the font size required for the text content, one of the font sizes with the smallest difference from the font size required for the text content is screened out from a predetermined font size database as the initial font size of the text content based on the target font, thereby improving the screening accuracy and reliability of the initial font size.

[0162] In yet another optional embodiment, after determining the candidate font sizes of the text content according to the display area information and the text length in step 206, the method may further include:

[0163] Determining whether the current readability of the candidate font size meets a preset readability condition;

[0164] When it is determined that the candidate font size does not meet the preset readability condition, the operation of adjusting the font size of the target font is stopped, and readability abnormality prompt information matching the candidate font size is output to prompt the user that the current readability of the candidate font size does not meet the readability condition;

[0165] When it is determined that the candidate font size meets the readability condition, an operation is triggered to re-determine whether the text content meets the preset text overflow condition based on the candidate font size, text length and display area information to obtain a second judgment result.

[0166] In the embodiment of the present invention, specifically, determining whether the current readability of the candidate font size meets a preset readability condition may include:

[0167] Determine whether the candidate font size is greater than or equal to a preset minimum font and less than or equal to a preset maximum font;

[0168] When it is determined that the candidate font size is greater than or equal to the minimum font and is less than or equal to the maximum font, determining that the current readability of the candidate font size meets a preset readability condition;

[0169] When it is determined that the candidate font size is smaller than the minimum font, or larger than the maximum font, it is determined that the current readability of the candidate font size does not meet the preset readability condition.

[0170] It can be seen that this optional embodiment can, after determining the candidate font size of the text content, first judge the readability of the candidate font size. When it is judged that the readability of the candidate font size is poor, stop adjusting the font size and output corresponding prompt information to the user, which is conducive to promptly prompting the user that the current font size affects the user's reading. When it is judged that the readability of the candidate font size is good, it triggers the subsequent operation of re-judging whether it overflows the text display device, which is conducive to improving the display integrity of the text content while ensuring the readability of the text content.
