The event organizer publishes the event through the event platform on the browser, and can generate and issue an electronic certificate through the event platform. The event organizer takes the award as the dimension, To set the certificates under the awards of the corresponding activities, steps S21-S24 in this application can be used for each award to generate and issue certificates.

S22: Based on the drawing attribute, synthesize the background image and certificate elements to obtain a certificate template corresponding to the electronic certificate;

Specifically, the background image and certificate elements are synthesized based on the drawing attributes, and the certificate template corresponding to the electronic certificate can be obtained. At this time, the certificate template does not contain the information of the active participants. Refer to Figure 4, which is a certificate in the embodiment of this application The schematic diagram of the template can be seen from Figure 4. The certificate template does not contain the name of the specific object. Therefore, when there are multiple award-winning users under one award, you only need to fill in the names of the award-winning users on the certificate template to realize batch generation. and issue a certificate.

S23: Obtain object information of at least one target object related to the electronic certificate;

Specifically, the target object refers to the object to which the electronic certificate needs to be issued. For example, for the award-winning user among the registered users of an event, the event organizer can select the winning user from the registered users as the target object, that is, set the user who can receive the electronic certificate object, the object information may refer to the name, nickname, screen name, etc. of the target object.

S24: Generate electronic certificates corresponding to each target object based on each object information and certificate template respectively.

In an optional implementation manner, step S23 may be implemented as:

In response to the selection operation of the target object among the candidate objects corresponding to the electronic certificate, the respective object information of each target object is acquired.

Specifically, the event organizer can see the information of all registered users (i.e. candidates), and can select the target object among the candidates for awarding. The event organizer can export all registration information under the event, and make a drop-down selection in the list. The selection range is all registered users corresponding to the award currently being set, and the selected registered users are used as the target object, and then imported after the operation is completed, so as to realize the function of awarding awards in batches. Based on the basic front-end interaction and back-end database, the element information and registration information under different activity awards can be recorded.

When generating a certificate template, the user can choose to upload the template or use the default template. When the user chooses to upload the template, in an optional implementation, step S21 can be implemented as:

In response to the template upload operation for the electronic certificate, obtain the certificate elements included in the template to be uploaded; in response to the image upload operation for the background image, obtain the background image; in response to the attribute setting operation for the certificate elements, obtain the certificate elements in the background image The location information and style information of the .

Among them, the drawing attribute includes at least the position information and style information of the certificate elements. When the user chooses to upload the template, the background image is uploaded by the user, and the terminal obtains the width and height of the background image, as well as the storage address of the background image. When generating the electronic certificate Get the background image according to the storage address.

When the user performs attribute setting operations, he can click anywhere in the background picture to adjust the position information of the certificate elements in the background picture, and the terminal device can obtain the coordinates (x, y) of the mouse click position from the upper left corner of the background picture, or enter the certificate The location information of the feature in the background image, for example, manually input or pull down to switch the coordinates under the background image. The property setting based on the above method is easy to operate and requires low user skills, and the user can preview the effect in real time when the user clicks any position in the background image to set the property, and when the user enters the position information to set the property, and then according to Preview the effect to make adjustments.

The terminal device also needs to record the ratio of the coordinates to the background image (rx, ry) = (x/width, y/height), and use the coordinates (x, y) and ratio (rx, ry) as position information; the user can also adjust The font, color, and font size that need to be set for the certificate elements, correspondingly, the terminal device records the font, color, and font size as style information.

Based on the above method, each event organizer can upload any required certificate template, set the position, style, and size of the text elements that need to be filled, and execute the batch award function on the platform. Award-winning users can preview and download after logging in to the platform Electronic certificates with respective names under the corresponding awards. After the event organizer generates the certificate template, there is no need for certificate synthesis. When the award-winning user previews or downloads, the certificate image is generated from the award-winning client. There is no need to generate and store the image on the server, and the system performance pressure of generating certificates is distributed to each award-winning On the client side, reduce the pressure on the server.

When the user chooses to use the default template, in an optional implementation manner, step S21 may be implemented as:

In response to the template default operation for the electronic certificate, the certificate elements included in the default template are obtained, the template picture is used as the background picture, and the default attribute is used as the drawing attribute.

Specifically, the user performs the template default operation, that is, the default template is used, and the background image and certificate attributes do not need to be additionally set.

It should be noted that, for the same award in the same activity, whether the user chooses to upload a template or use the default template, the elements of the certificate are the same, and the final generated electronic certificate contains different background images and drawing attributes of the elements of the certificate.

Referring to FIG. 6 , it is a schematic flow diagram of a method for generating a certificate template in the embodiment of the present application. The event organizer can generate a certificate template according to the steps in FIG. 6 , including the following steps:

S601: Determine whether to choose to upload a template, if it is, execute step S602, if not, execute step S606;

S602: Upload a background picture;

S603: Obtain certificate elements;

S604: Set the position information of the certificate element in the background picture;
