At present, the synthesis of pictures forms an indispensable link in the internet product line, and when general picture making and arranging tools (such as PS, joint and the like) are adopted to finish the process, taking an e-commerce scene as an example, commodity pictures are usually put into a designated entrance and category after merchants finish the making and arranging of the commodity pictures through own clients, and the whole process is manually finished by each merchant, so that a large amount of manpower resources are consumed. Secondly, when an activity atmosphere needs to be added for a certain scene, if preferential prices are marked on commodity head images, atmosphere banners are added, and the like, all merchants are required to manually modify own images through own clients respectively, and then the addition and modification of all commodity image contents under the specified category are completed. Besides a put-in scene, in order to improve the user participation of the activity, two-dimension codes are added to pictures to be shared with mainstream social media frequently so as to improve the user participation and enthusiasm, because many sharing graphs are generated based on user information customization, different users are required to provide customization development for specific scenes each time the functions are used, if the sharing graphs are generated through the front end, the sharing speed is slower on a machine with general performance, and the user experience is affected.

In addition, there are still many scenes where mass production of pictures is required, such as the production of active floor charts, the on-line and putting of combined goods with similar arrangement, etc., and it is still difficult for the current picture production mode and service flow to meet these requirements.

The above is a schematic scheme of a picture synthesis cloud platform in this embodiment. It should be noted that, the technical solution of the image synthesis cloud platform and the technical solution of the image synthesis method described below belong to the same concept, and details of the technical solution of the image synthesis cloud platform which are not described in detail are described in detail in the technical solution of the image synthesis method described below.

Fig. 2 shows a flowchart of a picture synthesis method according to an embodiment of the present application, which is applied to the picture synthesis cloud platform shown in fig. 1, as shown in fig. 2, and the method specifically includes the following steps:

step 202: and under the condition of receiving an uploading instruction, running a picture resource management unit in the picture synthesis cloud platform, and acquiring and storing picture resources through the picture resource management unit.

Specifically, the picture resource management unit is a unit module for managing picture resources in the picture composition cloud platform, and layer data of pictures managed in the picture resource management unit can be used for subsequent composition pictures. The image acquisition instruction is an instruction for instructing the image resource management unit to acquire the image resource, so that under the condition that the uploading instruction is received, the need to acquire and store the corresponding image is described, and at the moment, the image resource management unit in the image synthesis cloud platform can be operated, and the image acquisition and storage are realized through the image resource management unit.

It should be noted that, since the final goal of picture composition is to complete the production of pictures, other already designed picture resources are needed in the process of composing pictures, and these picture resources may be derived from pictures uploaded by uploaders, designed works, or pictures downloaded via the internet. Because of the diversity of the picture sources, the picture resource management unit is arranged in the picture composition cloud platform and is used for conveniently managing and storing the acquired picture resources.

In an optional implementation manner of this embodiment, the specific implementation process of obtaining and storing the picture resource by the picture resource management unit may be as follows:

acquiring uploading data;

Specifically, the uploading instruction is an instruction triggered by clicking an uploading control in an interactive interface of the picture synthesis cloud platform or calling an uploading interface externally provided by the picture synthesis cloud platform by a user, and the uploading instruction is used for uploading a picture prepared by the user for synthesizing the picture. In addition, the pictures uploaded by different users are often pictures required by the subsequent synthesized pictures, and some picture uploaders do not want to be used by other users, so that a corresponding storage space can be set for each user through the picture resource management unit for storing the pictures uploaded by the user.

It should be noted that, the user may upload the picture resources required for the subsequent picture composition to the picture composition cloud platform through the picture resource management unit, and the user may also autonomously select whether to compress the uploaded picture, i.e. the picture resource management unit further provides a function of automatic picture compression, thereby improving the picture uploading speed and saving the uploading traffic. After the picture is compressed and uploaded, the picture is stored in a storage space corresponding to the user, and only the uploading user can see the uploaded picture after the picture is uploaded.

In an optional implementation manner of this embodiment, after storing, by the picture resource management unit, the compressed upload data in a storage space corresponding to a user initiating the upload instruction, the method further includes:

Specifically, the adding instruction is an instruction triggered by clicking a sharing control in an interactive interface of the picture synthesis cloud platform or calling a sharing interface externally provided by the picture synthesis cloud platform by a user, and the adding instruction is used for sharing the picture uploaded by the user into a picture resource pool. The picture resource pool is used for storing pictures (i.e. shared pictures) that are available to all users.

It should be noted that, after the picture is compressed and uploaded, the picture is stored in a storage space corresponding to the uploading user, only the uploading user can see the uploaded picture, if the user wants to share the picture to others, the uploaded picture needs to be shared to a designated picture resource pool, and if the shared picture already exists, the user can select whether to be covered or not.

For example, fig. 3 is a schematic flow chart of uploading a picture provided by an embodiment of the present application, as shown in fig. 3, a user may click an upload control in a picture upload page provided by a picture synthesis cloud platform to trigger an upload instruction, and operate a picture resource management unit, so as to upload data, after the picture resource management unit detects the upload instruction, determine whether the upload data is a picture resource, and if not, terminate the upload; if yes, further judging whether a compression instruction aiming at the uploading data is received, and if not, judging whether corresponding resources exist in a storage space corresponding to a user initiating the uploading instruction; if yes, the picture compression module is called to compress, whether corresponding resources exist in the storage space corresponding to the user initiating the uploading instruction is judged after compression, if not, the uploading data are stored in the storage space corresponding to the user initiating the uploading instruction, a local mapping record is created, and the created local mapping record is used for supporting judgment of whether corresponding resources exist in the storage space corresponding to the user initiating the uploading instruction. And then, determining whether the uploaded picture needs to be added to a picture resource pool, and if so, adding the uploaded picture to the picture resource pool.

Step 204: and under the condition that a template creation instruction is received, a template management unit in the picture synthesis cloud platform is operated, and a corresponding picture template is created according to template attribute information carried by the template creation instruction.

Specifically, the template creation instruction is an instruction triggered by clicking a creation control in an interactive interface of the picture synthesis cloud platform or calling a creation interface externally provided by the picture synthesis cloud platform by a user, and is used for creating a new picture template, so that under the condition that the template creation instruction is received, the user is required to create a corresponding template, and at the moment, a template management unit in the picture synthesis cloud platform can be operated, and then a corresponding picture template is created through the template management unit. Template attribute information refers to information such as the size, background and included layers of a picture template, and the template attribute information is distributed and stored in a JSON string format.

It should be noted that, the picture template may provide a set of structure frames for mass production of pictures, where the set of structure only describes the arrangement position and basic attribute of the picture content, and then may be associated with the template instance, so as to provide a unique entry for mass production of pictures. After the picture template is provided, the picture can be synthesized only by providing data of a corresponding picture layer for the created template, and the subsequent picture synthesis process can be realized by a synthesis API and a bottom drawing engine provided by a picture synthesis cloud platform.

In addition, each picture template defines a style arrangement mode of different contents, and the picture templates can be composed of one or more layers, for example, the layers can be divided into the following layers according to functions: the three types of layers of pictures, words and two-dimensional codes can define the position and other attribute parameters (including general parameters and specific parameters) of each layer. Fig. 4 is a schematic diagram of a layer according to an embodiment of the present application, and as shown in fig. 4, the picture may be regarded as being formed by a background layer, a picture layer, a text layer, and a two-dimensional code layer.

In an optional implementation manner of this embodiment, after creating the corresponding picture template according to the template attribute information carried by the template creation instruction, the method further includes:

and setting a corresponding template identifier for the picture template under the condition that the picture template is established.

In particular, the template identifier is used for uniquely identifying a picture template, for example, the template identifier may be a template ID.

It should be noted that the version information refers to a version number of the picture template, and is used to identify modification conditions of the picture template.

copying the template to be modified to obtain a corresponding backup template;

and setting corresponding new version information for the updated template.

It should be noted that, the existing picture templates may be modified in the template management unit, so that corresponding version information is added for each picture template to identify the modification situation of the picture template. When each picture template is modified, the structure data of the picture template is not directly modified, but a new template is created, namely, the picture template needing to be modified is backed up, then the backed-up picture template is modified, and new version information is set for the new picture template obtained by modification.

For example, fig. 5 is a schematic diagram of editing a picture template according to an embodiment of the present application, where, as shown in fig. 5, a template size modification area is included in a template editing interface, and the size of the template (such as a template position, a width and height, a layout, etc.) can be adjusted through the area; the template editing interface also comprises a layer modifying area, wherein the layer modifying area displays the current layer setting condition of the picture template, and a user can adjust the layer position and content or add and delete layers in the layer modifying area.

It should be noted that, based on the application of the template in different scenes, multiple template instances can be created, the specific picture template is not invoked and modified later, but only the created template instance is operated, the created picture template can be used as a master, different detailed structures are added according to the application in different scenes, multiple template instances (i.e. sub-versions) are generated, and the picture is synthesized later through the template instances. That is, after one picture template is created, at least one corresponding template instance is also required to be created for the picture template, and the template instance is uniquely associated with the corresponding picture template, so that configuration information of the corresponding picture template can be read, and one picture template can be associated with a plurality of template instances.

In an optional implementation manner of this embodiment, for the second target picture template, at least one corresponding template instance is created, and the specific implementation process may be as follows:

In practical application, when creating the template instance, version information of the corresponding picture template can be determined, so that the template instance created for the new version information can be associated with the picture template of the new version, and the template instance created for the old version information is still associated with the picture template of the old version.

It should be noted that, from a functional point of view, the picture template already contains all information of the synthesized picture, and the picture can be synthesized directly using the configuration information in the picture template. However, because one picture template may be used in multiple scenes, directly associating a picture composition task with a picture template would result in a picture template that is not sufficiently single in responsibility; in addition, in an actual usage scenario, the photo template may be modified after creation, and if this photo template is being used by the on-line scenario at this time, an on-line accident may be caused. Therefore, a template example layer is added between the picture template and the picture synthesis process, the pureness of the template can be ensured, and the influence of the picture template modification on the on-line task can be effectively isolated. In addition, version information can be added for each picture template, each picture template does not directly modify the data of the picture template after being modified and released, but a new template is created, the template instance of the old version is still associated with the template before modification, and the template instance of the new version is associated with the template after modification.

For example, fig. 6 is a schematic diagram showing association between a picture template and a template instance, where, as shown in fig. 6, a user may access a template list through a template management page to determine whether a specified template exists, and if yes, return a template ID; if the specified template does not exist, a new template is created, and the corresponding template ID is returned. Associating the template ID to a corresponding template configuration for supporting a subsequent picture composition unit; and associating the template ID with a corresponding template instance ID, which is also used to support a subsequent picture composition unit.

Further, in order to ensure the safety of the picture template and prevent the existing picture template from being tampered, the picture synthesis cloud platform provided by the application can be further provided with a permission verification module, and the operations of creating and modifying the template can be verified through the permission verification module. Under the condition that an operation instruction aiming at a third target picture template is received, a right checking unit in a picture synthesis cloud platform can be operated to determine the operation right required by the operation instruction; determining whether a user initiating the operation instruction has the operation authority according to a user identifier carried in the operation instruction; and executing the operation corresponding to the operation instruction on the third target picture template under the condition that the user initiating the operation instruction has the operation authority.

It should be noted that any operation for a picture template needs to have a corresponding operation right, for example, only the creator of the picture template can modify the picture template, so when a modification instruction for the picture template is received, it needs to be determined whether the user initiating the modification instruction is the creator of the picture template, and if so, it is determined that the user has the modification right.

In an optional implementation manner of this embodiment, determining whether the user who initiates the operation instruction has the operation right according to the user identifier carried in the operation instruction includes:

In practical application, the rights control can be divided into rights division and member grouping, and for each picture template, the creator defaults to the rights of the owner, the rights can view, modify and delete the picture template under the rights, and the owners of the templates can transfer the rights to other users. In addition to the owner rights, three types of rights including maintainer, tourist and other users are included, and the three types of rights are not given to a specified user, but are specific to a specific group, wherein the maintainer has the rights of viewing, modifying and deleting the template, the tourist can only view the specified template, and other users cannot access the template.
