Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a sticker processing method and device, a storage medium and electronic equipment. The details will be described below separately.
Referring to fig. 1, fig. 1 is a schematic diagram of a system architecture of a sticker processing method according to an embodiment of the present application.
The electronic device may be a mobile terminal, such as a mobile phone, a tablet computer, a notebook computer, and the like, which is not limited in this application. In this embodiment, a plurality of applications having functions of still image processing (picture editing, photographing), moving image processing (video editing, video recording, video call), and the like are installed in the electronic device. For example, referring to fig. 1, the image processing APP2, the image processing APP3, the image processing APP4, and the like may be applications with functions of photographing, image editing, video editing, and/or video recording, and the like. In this application embodiment, image processing APP2, image processing APP3, image processing APP4 can have the AR sticker function, show through combining AR sticker and pending image, can obtain augmented reality image, reach the effect that virtual reality combines.
However, if each image processing application manages its own sticker, it will cause the same type of sticker to be operated and downloaded separately for each application, which will increase the workload of the sticker during operation, and also cause waste of storage space when users download the same type of sticker in multiple applications.
In order to avoid the above problem, embodiments of the present application provide a sticker management application that can independently manage sticker data, resources, and cache, so that each image processing application can access and call a sticker in the sticker management application, and can edit an image to be processed based on an acquired sticker.
In some embodiments, taking the Android (Android) system as an example, the sticker management application may be installed on an Android simulator or Android phone by an APK (i.e., Android installation package) file. After the sticker management application is installed, the application icon is not displayed on the desktop, and the user cannot directly operate the application. The sticker management application can provide various interfaces for the camera and the photo album to call so as to realize the picture pasting function of the camera and the photo album.
As shown in fig. 1, APP1 may be a sticker management application for storing sticker resource files, sticker thumbnail files, and sticker database files. The image processing APP2, the image processing APP3, the image processing APP4, and the like can read and write data by the sticker management application APP 1. For example, the sticker management application APP1 may provide a file access interface for other image processing applications (such as the image processing APP2, the image processing APP3, the image processing APP4, and the like) in a FileProvider manner, so that sticker data sharing may be implemented, and a similar sticker may be used in multiple applications at the same time, and only one download of the sticker management application APP1 is required. In the operation process, one sticker can be pushed to all needed image processing applications for display at one time, and the operation cost of the sticker and the storage space of a mobile phone of a user can be reduced. When a new application needs to be added with the function of the sticker, the functions can be quickly compatible.
For example, the user downloads the sticker M for use in a camera application carried by the system, and the sticker M is transferred to and stored in a sticker resource library corresponding to the sticker management application APP1, and updates the corresponding database. Subsequently, if the image editing application wants to use the sticker M, the sticker M stored in the image editing application is directly read by the sticker management application APP1 without downloading the sticker again after the image editing application is opened.
In practical applications, in order to avoid the presence of stickers that are not suitable for some image processing applications (for example, some stickers suitable for dynamic images need to detect the body movement of a person to achieve a specific effect, such a sticker resource is not suitable for static image processing because the static image is already a fixed image content and the body movement cannot be detected), each sticker may be configured with differentiated attributes, so that the sticker is only displayed in the suitable image processing applications.
In addition, the server may be a file server, an application server, or the like, and is used for storing file data, such as sticker data, uploaded by developers. As shown in fig. 1, when the electronic device needs to update the local database of the sticker management application APP1, the electronic device establishes a communication connection with the server through a connected network (such as a wireless network or a data network), and requests the server to send the latest sticker data to be added to the local electronic device, so as to update the sticker data of the local database of the sticker management application APP 1. Thus, the paster in the database is provided for the image processing application to process the image to be processed.
In some embodiments, the function of requesting the server-side latest sticker data may also be added entirely to the sticker management application APP 1. When the server detects data updating, a data updating prompt can be sent to the electronic equipment through a communication channel established with the electronic equipment monitor, and a data updating request is sent to the server based on the prompt information so as to update the latest sticker of the server to the local. In addition, the server can also directly send the update data to the electronic equipment when the network connected with the electronic equipment is a wireless network.
Any of the following transmission protocols may be employed, but are not limited to, between the electronic device and the server: HTTP (Hypertext Transfer Protocol), FTP (File Transfer Protocol), P2P (Peer to Peer, Peer to Server and Peer), P2SP (Peer to Server & Peer), and the like.
In an embodiment, a method for processing a sticker is provided, as shown in fig. 2, the process may be as follows:
101. a sticker acquisition request initiated by a first application is received.
The first application may be an application with functions of photographing, image editing, video editing, and/or video recording, and has a mapping function. By taking the AR sticker as an example, the AR sticker can be overlaid to the real image, the AR sticker and the image to be processed are combined and displayed, the augmented reality image can be obtained, and the effect of combining virtual and real images is achieved.
Specifically, the sticker acquisition request may be triggered when the user performs the mapping process on the to-be-processed through the first application. In practical application, a control for mapping processing can be set on an image editing page of first application, a mapping function can be triggered by clicking the control, and meanwhile, the first application is triggered to initiate a sticker acquisition request.
The first application may include an album application and a camera application of the system in the electronic device, and the sticker function of the album application and the camera application may be realized by calling sticker data in the sticker management application. In addition, the first application can also be other three-party applications with functions of photographing, picture editing, video recording and the like, such as an application of a certain camera, a certain show, a certain sound and the like.
102. And responding to the sticker acquisition request, and acquiring a sticker corresponding to the first application from a sticker set associated with the sticker management application according to a preset rule.
Wherein the sticker management application is for downloading and managing stickers, the collection of stickers being stored in a storage area allocated by the electronic device system for the sticker management application. The sticker management application may provide an interface or method for other applications to call so that other applications may obtain the sticker resources stored in the storage area for use through the interface or method provided by the sticker management application.
The first application corresponds to one or more stickers, each sticker corresponding to one or more applications. The one or more applications may be image processing applications with functions such as photographing, image editing, video editing, and/or video recording, and with mapping functions.
In the embodiment of the application, a plurality of image processing applications with functions of photographing, image editing, video editing and/or video recording and the like and a mapping function can be installed in the electronic device. In the system, a plurality of image processing applications and the sticker management application have an agreement. Through the protocol, a plurality of image processing applications can access files in a data directory of the sticker management application, such as a sticker resource file, a sticker thumbnail file, a sticker database file, according to a predetermined rule. In practical applications, there is no corresponding sticker data in the data directories of the image processing applications themselves. The sticker management application may provide an interface for file access to other image processing applications by way of FileProvider or ContentProvider. Through the method, the sticker data can be uniformly managed, one sticker can be called by a plurality of image processing applications, and the sharing of the sticker data is realized.
In some embodiments, the sticker acquisition request includes: the preset attribute and the attribute value of the first application. The step of "responding to the sticker acquiring request, acquiring a sticker corresponding to the first application from a sticker set associated with the sticker management application according to a preset rule" may include the following steps:
acquiring a target attribute and an attribute value of each sticker from a database associated with the sticker management application according to a preset attribute of the first application and a preset rule;
and acquiring the paster corresponding to the first application from the paster set according to the attribute value of the preset attribute and the attribute value of the target attribute.
Specifically, in the preset rule, a corresponding relationship between a preset attribute of the first application and a target attribute of the sticker may be established. In the database associated with the sticker management application, attribute information of each sticker may be stored, such as a sticker Identity (ID), size, resolution, source file storage path, configuration attributes, and/or other attribute information. Then, the identification information of the sticker to be acquired is determined through the difference or the same between the attribute value of the preset attribute and the attribute value of the target attribute. The identification information may be unique information such as a sticker ID and a source file storage path, and then the source file path may be directly or indirectly found, and a corresponding sticker is obtained from a sticker set associated with the sticker management application based on the source file path.
In some embodiments, the attribute value of the preset attribute comprises a first numerical value, and the attribute value of the target attribute comprises a second numerical value; the step of acquiring the sticker corresponding to the first application from the sticker collection according to the attribute value of the preset attribute and the attribute value of the target attribute may include the following steps:
according to a preset algorithm, carrying out operation processing on the first numerical value and the second numerical value to obtain an operation result;
and acquiring a sticker corresponding to the operation result and meeting the preset condition from a sticker set associated with the sticker management application as a sticker corresponding to the first application.
In the embodiment of the present application, the first numerical value and the second numerical value may be operated by a bitwise and operation, a bitwise or operation. Wherein:
1) bitwise AND operation
The operator of the bitwise and operation in common programming languages is "&". Assuming that a has a value of 1 and b has a value of 2, a and b can be converted into binary values of 01 and 10, respectively, and a & b can be obtained by bitwise and operation as 0.
2) Bitwise OR operation
The operator of bitwise or operation in common programming languages is "|". Assuming that a has a value of 1 and b has a value of 2, a and b can be converted into binary values of 01 and 10, respectively, and a | b ═ 3 can be obtained by bitwise or operation.
In this embodiment of the present application, an integer value of an independent flag bit may be set for each application installed in the electronic device, and flag bit values of any two applications are required, and after bitwise and operation, the result is 0. For example, the flags for multiple applications may be: 1 (i.e., 000001 in binary), 2 (i.e., 000010 in binary), 4 (i.e., 000100 in binary), 8 (i.e., 001000 in binary), … …, and so on. Then, the application suitable for each sticker can be predetermined, and the result of taking the flag bit of all the suitable applications as an attribute of the sticker is stored in the database file of the sticker according to bit or operation. For example, if a sticker is only suitable for applications with a flag bit of 1 and a flag bit of 2, the attribute value of the sticker is 1|2 ═ 3.
Therefore, if it is determined whether a sticker associated with the sticker management application is suitable for an image processing application, the attribute value of the sticker and the flag bit fixedly allocated by the image processing application (i.e., the attribute value of the preset attribute of the first application) can be bitwise and-calculated. If the operation value is equal to the zone bit of the image processing application in the operation result, the sticker is suitable for the image processing application; if the operation value is not equal to the flag bit of the image processing application in the operation result, it indicates that the sticker is not suitable for the image processing application. For example, refer to table 1 below:
| application name | Camera with a camera module | Photo album | Video call |
| Value of flag bit | 1 | 2 | 4 |
TABLE 1
For example, if a sticker is only applicable to a camera and an album, the attribute value of the sticker is 1|2 ═ 3. Then, the method for judging whether the sticker is suitable for the above 3 applications according to the bit sum algorithm is as follows:
1&3 ═ 2; the description applies to cameras
2&3 ═ 2; // description applies to photo albums
4&3 ═ 0; // description not applicable to video calls
During specific implementation, if more applications need to call the sticker data in the sticker management application, the new applications only need to be set with fixed flag bits according to requirements, and meanwhile, the attributes of the original stickers are modified. Therefore, the operation cost of the paster can be greatly reduced, and the extension of the function of the paster is also facilitated.
In some embodiments, the sticker acquisition request includes an application identification of the first application; the step of "obtaining a sticker corresponding to a first application from a sticker set associated with a sticker management application according to a preset rule in response to the sticker obtaining request" may include the following steps:
and acquiring sticker configuration information from a database associated with the sticker management application according to a preset rule, wherein the sticker configuration information comprises: mapping relation between the paster and the application identification;
and acquiring the paster corresponding to the first application from the paster set associated with the paster management application according to the application identifier and the mapping relation of the first application.
Specifically, when a sticker acquisition request is received, sticker configuration information is acquired from a database associated with a sticker management application according to a preset rule. Then, based on the application identification of the first application, i.e., the configuration information of the sticker, the identification information of the sticker that needs to be acquired is determined. The identification information may be unique information such as a sticker ID and a source file storage path, and then the source file path may be found directly or indirectly, and a corresponding sticker is obtained from a sticker set associated with the sticker management application based on the source file path.
103. And loading and displaying the acquired sticker in a sticker display page of the first application.
In some embodiments, the step of "loading and displaying a sticker in a sticker display page of a first application" may include the following flow:
receiving a page generation instruction;
generating a sticker display page of the first application according to the page generation instruction;
determining priority information of the paster;
and displaying the acquired sticker at the corresponding position in the sticker display page according to the priority information.
In the embodiment of the present application, the priority of the sticker needs to be set in advance. The priority setting mode can be various, for example, the priority can be set according to the number of the applications correspondingly suitable for the sticker; the priority can also be set according to the image characteristics of the sticker; the priority of the sticker may also be set according to user preferences based on machine learning.
Specifically, when the sticker data returned by the sticker management application is acquired, the page generation instruction for instructing generation of the sticker display page of the first application may be triggered and received. Then, based on the page generation instruction, the corresponding interface component is called, and a sticker display page of the first application is created. Then, the acquired sticker is displayed at a corresponding position in the sticker display page according to the priority information of the acquired sticker.
In some embodiments, to speed up the display, a thumbnail image of the sticker may be displayed in the sticker display page. When a user clicks and selects a thumbnail of a certain sticker to process an image to be processed, corresponding original stickers can be obtained from a sticker set associated with the sticker management application and are overlaid on the image to be processed for display in a matched mode.
In the application, the sticker data associated with the sticker management application can be shared by a plurality of applications, so that conflicts are easily caused when resources are called, for example, when the application A calls the data, the application B also calls the data, so that the process cannot judge which calling operation is executed, and the process is blocked. Therefore, in some embodiments, after loading and displaying the obtained sticker in the sticker display page of the first application, the following process may be further included:
when a sticker acquisition request initiated by a second application is detected, removing the occupation of the sticker by the first application;
acquiring a sticker corresponding to the second application from a sticker set associated with the sticker management application according to a preset rule;
and loading and displaying the acquired sticker in a sticker display page of the second application.
Similarly, the second application may include an album application and a camera application of the electronic device, and the sticker function of the album application and the camera application may be implemented by calling sticker data in the sticker management application. In addition, the second application can also be other three-party applications with functions of photographing, picture editing, video recording and the like, such as an application of a certain camera, a certain show, a certain sound and the like.
It should be noted that the first application is not the same application as the second application. For example, when the first application is a system camera application, the second application may be a system photo album application.
For the system camera application, after the system camera is started, the sticker (one or more stickers) matched with the system camera application can be acquired from the sticker set stored in the corresponding storage area of the sticker management application by calling an interface of file access provided by the sticker management application, and thumbnails of the stickers are loaded into a sticker display area of the system camera application. When a user selects a needed paster from the paster display area, a source file of the paster is obtained and loaded to a preview image in a current preview frame of a system camera to be overlaid and displayed, and therefore the paster in the paster management application is called.
For the system album application, after the system album is opened, a certain image in the album is selected and opened. Then, the sticker(s) matching the system camera application can be obtained from the set of stickers stored in the storage area corresponding to the sticker management application by calling the interface for file access provided by the sticker management application, and thumbnails of these stickers can be loaded into the sticker display area of the system camera application. And when a user selects a needed paster from the paster display area, obtaining a source file of the paster, loading the source file to the opened image, and overlapping and displaying the source file so as to realize the calling of the paster in the paster management application.
Specifically, when a calling operation of the second application for the sticker data in the sticker management application is detected, the process of the sticker data called by other current applications is covered.
In some embodiments, when the user does not want some of the stickers that have been downloaded, the unwanted stickers can be deleted by the first application, the second application, or other application that can access the sticker management application. That is, in some embodiments, the following process may also be included:
receiving a deleting instruction aiming at a target paster displayed in the paster display interface;
removing the target sticker from the collection of stickers according to a delete instruction.
Specifically, some unnecessary stickers can be deleted on the sticker display interface of the application currently calling the file access interface provided by the sticker management application, so as to make more storage space for the electronic device.
In the embodiment of the application, the function of requesting the latest sticker data of the server is also added to the sticker management application. For example, when the server detects a data update, a data update reminder can be sent to the electronic device through a communication channel established with the electronic device, and a data update request is initiated to the server based on the reminder information so as to update the latest sticker of the server to the local.
In some embodiments, if the corresponding sticker is not obtained in the local sticker resource library, the latest sticker data may also be obtained from the corresponding server by the sticker management application, so as to obtain the corresponding sticker from the updated sticker resource library. That is, the method may further include the following steps:
if the sticker corresponding to the first application is not acquired from the sticker set, sending a data updating request to a server;
receiving the sticker resource data returned by the server according to the data updating request;
and updating the sticker set and the database associated with the sticker management application based on the received sticker resource data, and re-executing the sticker acquisition operation.
The server may be a file server, an application server, or the like, and is used for storing sticker data uploaded by developers, such as AR stickers.
In some embodiments, the server may also directly issue the update data to the electronic device when the network to which the electronic device is connected is a wireless network.
In some embodiments, the electronic device may also proactively request the sticker resource data from the server. For example, when the sticker matching the image processing application cannot be found in the local file of the sticker management application, the electronic device may establish a communication connection with the server through a connected network (e.g., a wireless network or a data network), and request the server to send the latest sticker data to be added to the local of the electronic device, so as to update the sticker data of the local database associated with the sticker management application. The sticker in the database is thus provided to the image processing application for processing the image to be processed.
In particular implementation, the present application is not limited by the execution sequence of the described steps, and some steps may be performed in other sequences or simultaneously without conflict.
As can be seen from the above, the sticker processing method provided by the embodiment receives a sticker acquisition request initiated by a first application; responding to the sticker acquisition request, and acquiring a sticker corresponding to a first application from a sticker set associated with a sticker management application according to a preset rule; loading and displaying the sticker in a sticker display page of the first application. The scheme of the application can uniformly manage the sticker resources through the sticker management application, can share the access and the calling of the resources for the multiple applications, does not need to construct a sticker resource library independently for each application, and reduces the operation cost and the occupation of storage space of the sticker resources.
In an embodiment, another method for processing the sticker is further provided, as shown in fig. 3, taking the first application as a video recording application as an example, the process may be as follows:
201. the electronic equipment calls a system camera to acquire a current image in real time through the video recording application.
The video recording application has a mapping function, and may be a camera application of the system, for example.
In addition, the camera of the system is a built-in camera of the electronic equipment, and can be a single camera or a double camera. For example, the dual cameras may include a wide-angle camera and a telephoto camera, wherein the wide-angle camera may be used as a main camera of the electronic device, and the telephoto camera may be used as a sub-camera. When the image of the current scene of electronic equipment is shot to needs, this electronic equipment can only shoot through its wide-angle camera module, also can shoot with long burnt camera jointly through its wide-angle camera. In other embodiments, three cameras and the like may also be used, which is not further limited in this application.
202. The electronic equipment receives a sticker acquisition request initiated by a video recording application, wherein the sticker acquisition request comprises a flag bit of the video recording application.
Specifically, the sticker acquisition request may be triggered when the user performs the mapping process on the to-be-processed image through the video recording application. In practical application, a mapping control can be set on a recording interface of a video recording application, a mapping function can be triggered by clicking the mapping control, and meanwhile, the first application is triggered to initiate a sticker acquisition request.
In this embodiment of the present application, an integer value of an independent flag bit may be set for each application installed in the electronic device, and flag bit values of any two applications are required, and after bitwise and operation, the result is 0. For example, the flags for multiple applications may be: 1 (i.e., 000001 in binary), 2 (i.e., 000010 in binary), 4 (i.e., 000100 in binary), 8 (i.e., 001000 in binary), … …, and so on.
203. And the electronic equipment traverses the attribute value of the target attribute of each sticker from the database associated with the sticker management application according to the flag bit and the preset rule.
Wherein the sticker management application is for downloading and managing stickers, the collection of stickers being stored in a storage area allocated by the electronic device system for the sticker management application. The sticker management application may provide an interface or method for other applications to call so that other applications may obtain the sticker resources stored in the storage area for use through the interface or method provided by the sticker management application.
The first application corresponds to one or more stickers, each sticker corresponding to one or more applications. The one or more applications may be image processing applications with functions such as photographing, image editing, video editing, and/or video recording, and with mapping functions.
Specifically, in the preset rule, a corresponding relationship between a flag bit of the video recording application and a target attribute of the sticker may be established. The sticker management application may be associated with a database in which attribute information for each sticker may be stored, such as a sticker ID, size, resolution, source file storage path, configuration attributes, and/or other attribute information.
In the embodiment of the application, the application suitable for each sticker needs to be preset, and then the result of taking the flag bits of all the suitable applications is stored in the database file of the sticker as one attribute of the sticker according to bitwise or operation. For example, if a sticker is only suitable for applications with a flag bit of 1 and a flag bit of 2, the attribute value of the sticker is 1|2 ═ 3.
