[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0045] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0046] In this application embodiment, the terms "module" or "unit" refer to a computer program or part of a computer program that has a predetermined function and works with other related parts to achieve a predetermined goal, and can be implemented wholly or partially using software, hardware (such as processing circuitry or memory), or a combination thereof. Similarly, a processor (or multiple processors or memory) can be used to implement one or more modules or units. Furthermore, each module or unit can be part of an overall module or unit that includes the functionality of that module or unit.

[0047] It is understood that in the specific embodiments of this application, data such as user information are involved. When the above embodiments of this application are applied to specific products or technologies, user permission or consent is required, and the collection, use and processing of related data must comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0048] Please see Figure 1 The diagram shown is an implementation environment provided in this application embodiment. The implementation environment includes a terminal 110 and a server 120, wherein the terminal 110 and the server 120 can communicate through a wired or wireless network connection.

[0049] Terminal 110 includes, but is not limited to, mobile phones, computers, smart voice interaction devices, smart home appliances, vehicle terminals, and aircraft. Terminal 110 runs client software, such as an application (App), that has poster generation functionality. This application can be a standalone application or a subroutine within an application. Specifically, the application can be a dedicated poster generation application or an application that includes poster generation functionality and other interactive functions, such as e-book reading and social networking functions. Users of terminal 110 can log in to the application using pre-registered user information to access the poster generation service. It should be noted that terminal 110 can refer to one of multiple terminals; this embodiment only uses terminal 110 as an example. Those skilled in the art will understand that the number of terminals 110 can be more or less.

[0050] Server 120 can provide background services for applications in terminal 110, specifically poster generation services. Specifically, server 120 can display a poster template configuration page to its users through terminal 110. Users of terminal 110 can configure a target poster template according to their personal needs based on this page. Terminal 110 sends the poster template configuration data configured on the page to server 120. Server 120 can then obtain the poster template configuration data configured by the user of terminal 110, which includes a target image and text location information. This text location information indicates the layout of the poster text within the target image. Server 120 then stores the target poster template in the poster template library based on this configuration data and, in response to a poster generation request sent by the user of terminal 110 for the target poster template, retrieves the target image and text. The system includes a regional information component, where the poster generation request includes poster text information to be displayed on the target poster image to be generated. This then calls a rendering program instance to generate a target poster image with the target image as the background and including the poster text information, based on the target image, the regional text information, and the poster text information. The layout of the poster text information in the target poster image matches the regional text information. The target poster image is then returned to the user of terminal 110. This enables user-defined poster templates and allows for the automatic generation of personalized target poster images containing user-inputted text based on these templates. This improves the flexibility and efficiency of poster image generation, meets users' personalized information sharing needs, and encourages users to share poster images, thereby increasing the information dissemination rate.

[0051] It should be noted that the server involved in the embodiments of this application can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms.

[0052] In a specific application scenario, a poster generation request can be initiated through an application with sharing capabilities. This application can provide users with a variety of images with brand logos and text layouts to choose from. Users can then select their favorite images and text layouts to obtain a personalized target poster template. This personalized target poster template is then combined with the text information they want to share to create a personalized target poster image, which can then be shared. This allows users to experience a rich and diverse sharing experience, and they will feel that sharing is fresh and personalized, thus encouraging them to share more actively and increasing the information dissemination rate.

[0053] In another specific application scenario, the poster generation request can be initiated based on an e-book reading application. Specifically, when a user reads an e-book using an e-book reading application, they can generate a personalized target poster image based on their written book reviews or sentences of interest from the text using the poster generation method of this application embodiment. This personalized target poster image can then be shared, for example, to a social media platform. When generating their personalized target poster image, the user can select their preferred image and layout to obtain a personalized target poster template. This personalized target poster template is then combined with the text information they wish to share (such as book reviews or sentences of interest from the text) to obtain the personalized target poster image.

[0054] Please see Figure 2 The diagram shown is a flowchart illustrating a poster image generation method provided in an embodiment of this application. This method can be applied to... Figure 1 The server in the middle. It should be noted that this specification provides the operation steps of the method as described in the embodiments or flowcharts, but based on conventional or non-inventive labor, more or fewer operation steps may be included. The order of steps listed in the embodiments is only one of many possible execution orders and does not represent the only execution order. In actual system or product execution, the methods shown in the embodiments or drawings can be executed sequentially or in parallel (e.g., in a parallel processor or multi-threaded processing environment). Specifically, as shown in the figures... Figure 2 As shown, the method may include:

[0055] S201, Obtain the poster template configuration data of the target object based on the poster template configuration page.

[0056] The poster template configuration data includes a target image and text location information, wherein the text location information indicates the layout of the poster text in the target image.

[0057] The target object can be the account of the end user to whom the target poster image is to be generated.

[0058] The target image can be an image selected by the target object. The source of the target image can be an existing image in the terminal corresponding to the target object, a current screenshot of the target object, a real-time captured image, or an image selected from the Internet.

[0059] Textual geographic information can indicate the layout of poster text in the target image from multiple dimensions. Specifically, these multiple dimensions can include the region location dimension, font dimension, and region format dimension. The region location dimension can include the start position, end position, and size of the region (including the height and width of the region), the font dimension can include the font size and font color, and the region format dimension can include the text alignment within the region.

[0060] In specific implementation, the poster template configuration page can be implemented based on multiple configuration components. These multiple configuration components may include a first configuration component for configuring the target image and a second configuration component for configuring text and geographic information. Thus, the server can respond to the poster template configuration request of the target object and display the poster template configuration page on the terminal corresponding to the target object based on these multiple configuration components. This allows the target object to perform personalized poster template configuration based on the poster template configuration page to obtain poster template configuration data.

[0061] S203, Based on the poster template configuration data, store the target poster template in the poster template library.

[0062] Specifically, the database fields that the poster template library saves for poster templates can be:

[0063] {

[0064] ID: Template ID

[0065] ImgUrl: The URL of the image

[0066] Textareas: Text-based geographic information}

[0067] Based on this, in some exemplary embodiments, such as Figure 3 As shown, step S203 above may include the following when implemented:

[0068] S301, store the target image in the poster template configuration data to a designated storage space, and determine the storage address of the target image in the designated storage space.

[0069] The specified storage space can be a content delivery network or the server's local storage space. The storage address of the target image can indicate the storage location of the target image in the specified storage space. Specifically, the storage address of the target image can be in the form of a Uniform Resource Locator (URL).

[0070] S303, determine the target template identifier corresponding to the target poster template.

[0071] The target template identifier is used to uniquely identify the target poster template, and the server can generate this unique target template identifier.

[0072] S305, establish a correspondence between the target template identifier, the storage address, and the text regional information in the poster template library.

[0073] In the above embodiments, by establishing a correspondence between the target template identifier, storage address, and text regional information in the poster template library to store the configured target poster template in the poster template library, the amount of data in the poster template library can be reduced, which is conducive to improving the efficiency of subsequent poster generation based on the poster template library.

[0074] In practical applications, after establishing the correspondence between the target template identifier, the storage address, and the textual geographic information in the poster template library, the storage address of the target image can be returned to the terminal corresponding to the target object for display to the target object.

[0075] S205, in response to the poster generation request sent by the target object for the target poster template, the target image and the text region information are obtained, the poster generation request including poster text information for display on the target poster image to be generated.

[0076] Specifically, the target device's terminal can display a poster generation entry point (such as a corresponding control). When the target device triggers this entry point, it can display the target poster template in the poster template library, such as displaying the target template identifier for the target device to select. At the same time, the terminal can also obtain the poster text information input by the target device, such as a book review or a sentence of interest, and then send a poster generation request for the target poster template to the server based on the target template identifier selected by the target device and the input poster text information.

[0077] Based on this, see further. Figure 3 In response to a poster generation request sent by the target object for the target poster template, the server may obtain the target image and the textual geographic information, including:

[0078] S307, Obtain the poster generation request sent by the target object for the target poster template, wherein the poster generation request includes the target template identifier.

[0079] S309, determine the target correspondence in the poster template library that matches the target template identifier.

[0080] Specifically, the correspondence between the template identifier in the poster template library and the target template identifier is determined as the target correspondence.

[0081] S311, Obtain the textual regional information in the target correspondence relationship, and the storage address in the target correspondence relationship.

[0082] In the above embodiments, the target template identifier in the poster generation request is used to find the matching target correspondence in the poster template, thereby obtaining the text regional information and the storage address of the target image in the target correspondence, which helps to improve the efficiency of poster generation.

[0083] S207, Invoke a rendering program instance, and generate a target poster image with the target image as the background and including the poster text information based on the target image, the text region information and the poster text information, wherein the layout of the poster text information in the target poster image matches the text region information.

[0084] The rendering program instance is a browser front-end framework running on the server side, specifically a Node.js framework running on the server side. It can be a headless browser instance. This headless browser instance can perform rendering processing based on the target image, the text regional information, and the poster text information, and generate a rendering screenshot, which is the target poster image.

[0085] Therefore, in some exemplary embodiments, see below. Figure 3 The above step S207 may include the following when implemented:

[0086] S313, invoke a headless browser instance to access the storage address, create a first page based on the target image in the storage address, the size of the first page matches the size of the target image, and the first page uses the target image as its background.

[0087] Specifically, a new browser page can be created using a headless browser, and this browser page can be navigated to the storage address of the target image to obtain the target image. The size of the target image can then be determined, and the size of the browser page can be adjusted according to the size of the target image so that the size of the browser page matches that of the target image. For example, if the size of the target image is (width:600, height:800), the size of the browser page created above can be adjusted to (width:600, height:800) using the "page.setViewport()" method. At the same time, the target image can be set as the background of the browser page created above by using the "page.setContent()" method, thus obtaining the first page.

[0088] S315, Based on the text location information and the poster text information, add a target block-level element to the first page to obtain the target page.

[0089] The target block-level element can contain textual regional information and poster text information. Object. In specific implementation, the "page.addStyleTag()" and "page.evaluate()" methods can be used to create the target block-level element based on the text location information and poster text information, and then add it to the first page to obtain the target page.

[0090] S317, Take a screenshot of the target page to obtain the target poster image.

[0091] In practice, the "page.screenshot()" method can be used to take a screenshot of the target page, and the resulting image will be the target poster image.

[0092] In the above implementation, the storage address of the target image is accessed by calling a headless browser. A first page with the target image as the background is created based on the target image in the storage address. Then, target block-level elements are added to the first page based on the text region information and poster text information to obtain the target page. The target page is then screenshotted to obtain the target poster image. This allows for the automatic addition of poster text information to a custom target poster template to obtain the target poster template, thus improving the efficiency of generating personalized poster images.

[0093] In some exemplary embodiments, in order to stably generate poster images under high load and thus improve the stability of poster image generation, step S313 above may include, when implementing the call to the headless browser instance to access the storage address:

[0094] Send a request to the instance repository to obtain a headless browser instance, so that the instance repository responds to the request, searches for an idle headless browser instance in the instance repository, and returns a response result based on the search result;

[0095] Upon receiving the first response result returned by the instance repository, the request to acquire the headless browser instance is added to the waiting queue, so that when the instance repository determines that there is an idle headless browser instance, it returns a second response result based on the idle headless browser instance and in the order of the headless browser instance acquisition requests in the waiting queue; the first response result indicates that no idle headless browser instance was found, and the second response result includes any idle headless browser instance;

[0096] Upon receiving the second response result returned by the instance resource library, the idle headless browser instance in the second response result is invoked to access the storage address.

[0097] The instance resource library includes multiple pre-created headless browser instances. Each headless browser instance can be in an idle or non-idle state. A non-idle state indicates that the instance is currently occupied due to invocation, while an idle state indicates that the instance is not currently being invoked. In practical applications, each headless browser instance can also have a usage count attribute, which records the number of times the instance has been used.

[0098] In practice, a resource factory can be defined first, containing methods for creating, destroying, and validating headless browser instances. In the method for creating a headless browser instance, the `puppeteer.launch()` method can be used to create the instance and initialize a usage count property to record the number of times the instance has been used. In the method for destroying a headless browser instance, the `instance.close()` method can be used to close the instance. In the method for validating a headless browser instance, the return value of the provided validator function and the usage count of the instance can be checked to see if they exceed the maximum usage count. If they do, the instance is destroyed.

[0099] Next, you can create an instance repository. For example, you can use the genericPool.createPool() method to create an instance repository, passing in the resource factory defined above and some configuration parameters. These configuration parameters can include the instance repository's capacity limit, capacity limit, and resource acquisition timeout. The capacity limit indicates the upper limit of the total number of headless browser instances in the instance repository, the capacity limit indicates the lower limit of the total number of headless browser instances in the instance repository, and the resource acquisition timeout indicates the longest response time for the instance repository to request a headless browser instance. That is, if no idle headless browser instance is found within the resource acquisition timeout period, it indicates that the resource acquisition has failed.

[0100] The instance repository can determine the status of each headless browser instance based on its usage history. If a headless browser instance is invoked, it is currently in a non-idle state until it is released back to the instance repository, at which point it will be in an idle state. The usage count of each headless browser instance can be recorded in a corresponding usage count attribute. The instance repository can then determine whether the usage count of a given headless browser instance exceeds its maximum usage count. If it does, the instance can be destroyed to improve the stability of each headless browser instance.

[0101] In the above implementation, the server sends a request to the instance repository to obtain a headless browser instance. In response to this request, the instance repository searches for an idle headless browser instance and returns a response result based on the search result. It is understood that the search result includes "found" and "not found." If an idle headless browser instance is found, it indicates that resources are currently available. In this case, the instance repository can return a second response result based on any idle headless browser instance, which includes that idle headless browser instance. If no idle headless browser instance is found, it indicates that no resources are currently available. In this case, the instance repository returns a first response result, which indicates that no idle headless browser instance was found.

[0102] Upon receiving the first response, the server adds the request to acquire the headless browser instance to a waiting queue, awaiting resource availability. Specifically, when the instance repository determines that an idle headless browser instance exists, it returns a second response based on that idle instance and in the order of the headless browser instance acquisition requests in the waiting queue. Upon receiving the second response, the server can access the storage address of the target image using the idle headless browser instance mentioned in the second response, thereby achieving both flexible customization of poster images and high efficiency and availability, significantly improving the stability of poster generation.

[0103] For example, after taking a screenshot of the target page in step S317 to obtain the target poster image, the method may further include: releasing the invoked headless browser instance so that the instance resource library determines that the headless browser instance is in an idle state.

[0104] In specific implementation, a preset method can be added to the instance repository. This preset method accepts a function as a parameter. The preset method is used to obtain a headless browser instance from the instance repository, then pass the headless browser instance to the function. After the function finishes execution, regardless of whether the execution result is successful or not, the headless browser instance will be returned to the instance repository, thereby releasing the called headless browser instance. This allows the instance repository to determine that the headless browser instance is in an idle state, realizing the reuse of headless browser instances in the instance repository.

[0105] S209, Return the target poster image to the target object.

[0106] Specifically, the server can either directly return the target poster image to the target object after generating it, or it can first store the target poster image and obtain its access address, and then return the access address of the target poster image to the target object, so that the target object can obtain the target poster image based on the access address.

[0107] As can be seen from the above technical solutions of the embodiments of this application, the embodiments of this application realize user-defined poster templates and can automatically generate personalized target poster images containing user-input text based on the user-defined poster templates. This improves the flexibility and efficiency of generating poster images, meets users' personalized needs for information sharing, and helps to increase users' willingness to share based on poster images, thereby increasing the information dissemination rate.

[0108] In some exemplary embodiments, to further improve the flexibility of personalized poster image generation and increase information dissemination rate, after the aforementioned step S209, the method may further include:

[0109] In response to the adjustment instruction for the target poster template, the poster template configuration data is displayed on the poster template configuration page;

[0110] Obtain the adjusted poster template configuration data based on the poster template configuration page;

[0111] The target poster template stored in the poster template library is updated based on the adjusted poster template configuration data.

[0112] When a target audience perceives that the target poster image displayed on a terminal does not meet expectations regarding the target poster template, they can adjust the target poster template. Specifically, the poster template configuration page can provide template adjustment entry points (such as corresponding controls) for the target poster template. When these entry points are triggered, an adjustment command for the corresponding target poster template can be sent. In response to this command, the server can retrieve the poster template configuration data for the target poster template from the poster template library and display this data on the poster template configuration page. This allows for adjustments to the displayed poster template configuration data. After the adjustment is complete, the server obtains the adjusted poster template configuration data based on the poster template configuration page and then updates the target poster templates stored in the poster template library based on this adjusted data.

[0113] Updating the target poster template stored in the poster template library based on the adjusted poster template configuration data can include updating the target image and / or updating the text and regional information.
