Detailed Description

Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

In the technical scheme of the disclosure, the acquisition, storage, application and the like of the personal information of the related user all accord with the regulations of related laws and regulations, and do not violate the good customs of the public order.

Sharing poster pictures as described above is a common information sharing method at present. For example, after a user publishes his or her work (video, picture, etc.) using a WeChat applet, etc., the user wants to share his or her work and wants to be seen by more people, one is to use the applet's own ability to directly share the current work with a friend, and the other is to generate a poster picture with an applet code jumping to the work and store the poster picture locally, and then send the picture to the friend or to a friend circle, etc. The sharing mode is good, but the displayed content of the poster is in a fixed style, the posters sent by different people are only different in content such as works and titles, and users cannot modify the content and the style of the posters in a personalized mode. In addition, for small program developers, poster typesetting and the like generated by different works and classifications proposed by a product manager are completely different, so that not only a new poster needs to be redeveloped, but also a new version needs to be reissued for support, dynamic update of a poster template is not facilitated, and the management cost is increased.

Based on the above, the present disclosure provides a method, an apparatus, an electronic device, a storage medium, and a computer program product for generating a poster, so that a user can customize poster style content according to the actual needs of the user, and the requirements of personalized posters are met.

According to an embodiment of the present disclosure, a method for generating a poster is provided.

Fig. 1 is a schematic illustration of a flow of a method for generating a poster according to an embodiment of the present disclosure. As shown in fig. 1, a method for generating a poster provided by an embodiment of the present disclosure includes:

s101, receiving a poster template issued by a management platform and a set data specification, wherein the poster template is generated based on the set data specification;

s102, receiving a first input of a user, and modifying the poster template based on the set data specification in response to the first input;

s103, generating a poster picture based on the modified poster template.

For example, the method for generating a poster provided by the embodiment of the disclosure can be applied to various applets such as WeChat applets, which can be loaded to various mobile terminals such as smart phones, tablets and the like. Of course, the method for generating the poster provided by the embodiment of the disclosure is not limited to be applied to the applet, and can be applied to other various program products or devices with poster generation capability.

The management platform is, for example, an applet management platform, and is used for managing and updating the applet content and the like.

The poster template may be generated by an operator or designer drawing from different target users at the management platform. For example, a poster template appropriate for a training institution is drawn for the training institution and a poster template appropriate for a government institution is drawn for the government institution. And in order to dynamically update the poster template on the management platform instead of directly fixing the main content and style of the poster template in the applet code as described above, in the embodiment of the present disclosure, a data specification for drawing the poster template is set, the data specification defines the format, drawing rules, and the like of the poster, and an operator or designer can draw different types of poster templates based on the data specification, and modify and update the poster template.

Illustratively, in the embodiment of the present disclosure, the set data specification is, for example, a JSON (JavaScript Object Notation) drawing specification. Poster templates are implemented by html5 based on the JSON drawing specification. And each view of the poster template supports dragging, and the JSON drawing specification is generated by dynamically recording the position and other styles.

In S101, the front end such as an applet receives a poster template drawn by the back end and a set data specification from a management platform. The poster template is generated based on the set data specifications.

In the embodiment of the present disclosure, since the poster template is generated by defining the data specification of the poster and based on the data specification, the poster template is not directly fixed in the code of the applet or the like. Therefore, after the front end of the small program receives the poster template, the user is allowed to modify the poster template based on the set data specification, so that personalized customization of the poster is realized, and the user experience is improved.

In S102, a front end, such as an applet, receives a first input from a user and modifies the poster template based on the set data specifications in response to the first input.

In an embodiment of the disclosure, the first input comprises, for example, a user dragging, zooming, deleting or editing operation of a view in the poster template. The first input represents information input by a user operating on respective views in a poster template provided at the front end of, for example, an applet. The first input represents a modification action of a certain view or certain views in the user poster template, such as dragging the position of the view, zooming or deleting the view, and editing the content in the view, such as editing the text in the view. Or to switch between multiple views to edit different views.

Upon receiving the first input by a user, modifying the poster template based on the set data specification in response to the first input. For example, a user edits the textual content of a view in the poster template, the poster template is modified based on the edited textual content. For another example, if the user adjusts the position of a view in the poster template, the poster template is modified based on the adjusted position of the view.

And in the process of modifying the poster template, rendering is carried out based on the set data specification, so that the updated poster template is obtained.

Illustratively, in embodiments of the present disclosure, the modification of the poster template may be achieved based on the following principles: for example, the front end of the applet constructs a Palette for generating poster pictures according to the set data specification issued by the management platform, and then transmits the Palette to the Painter in the running process of the program. The Painter calls Pen (paintbrush), draws a corresponding dynamic template according to the contents of the paintte, and when the dynamic template is used, the Painter supports dragging, zooming and deleting operations of a user on a poster view (view) in a default mode, so that the freedom degree of the poster template is increased. The style of the operation icon (icon) and the operation box can be customized through the customamactionsstyle. The initial template is imported through the dance palette, and when the template level is refreshed subsequently, the imported value of the dance plette is modified. action is used for modification of the incoming single view (view) level. If the incoming view (view) has an identity (id), the view (view) with the id matching will be overwritten, and if no id exists, the currently selected view will be overwritten by default. The currently selected view (view) can be obtained through touch and or the deletion operation of the user is sensed. If the view (view) is to be scaled, a scalable: true value needs to be configured in css, and if the view (view) is to be deleted, a scalable: true value needs to be configured in css; further customization is achieved by dynamically updating the view (view) attributes, such as replacing the view url, modifying the text, and modifying the text style.

In S103, the poster picture generated based on the modified poster template may be locally stored, so that the user may share the poster picture.

Illustratively, in an embodiment of the present disclosure, the method for generating a poster further comprises:

receiving a second input from the user, and canceling or restoring the modification to the poster template in response to the second input. That is, in the disclosed embodiment, the ability to undo a user's custom editing behavior is supported.

The principle of realizing the functions of canceling and restoring modification is as follows: maintaining two arrays of future (future) and history (history) in a poster rendering page, respectively recording the changes which need to be recovered and need to be cancelled, and when a modification operation is performed, firstly transferring the current state of the view into the history array before modification, and simultaneously emptying the future (future) array. And if the click is cancelled, transmitting the view at the click moment into a future (future) array, and updating the poster template by using the view at the top of the history array. If the click recovers, the view at the moment of the click is imported into the history array, and the poster template is updated with the view at the top of the future array.

Exemplarily, in an embodiment of the present disclosure, before S102, the method for generating a poster further includes: receiving a third input from the user and providing the poster template to the user in response to the third input. The third input is, for example, a user operation of a front-end control. The front-end control is configured to trigger a request for generating the poster when operated, and the front end enters the process of generating the poster. Illustratively, the front-end control is, for example, an operation button provided by the applet end, and the first input is a click or a press of the operation button. When the user clicks or presses the button, the operation of generating the poster is triggered, and the applet provides the poster template issued by the management platform for the user, for example, the poster template is displayed in the page of the applet.

In the embodiment of the disclosure, when the poster template is modified, in order to reduce the drawing time, only necessary redrawing operation is performed, instead of refreshing the whole template every time, so that the interaction experience is improved. To achieve the above capability, in an embodiment of the present disclosure, the modifying the poster template based on the set data specification in response to the second input comprises:

and determining a view to be modified in the poster template, and redrawing the view to be modified based on the first input and the set data specification.

That is, in the embodiment of the present disclosure, when the poster template is modified, only a single view that needs to be modified is redrawn, instead of redrawing all views, so that due to the reduction of the drawing content, the time for completing redrawing is greatly shortened, and the interactive experience is improved.

Embodiments of the present disclosure also provide a method for redrawing a poster.

FIG. 2 is a schematic flow diagram of a method for redrawing a poster according to an embodiment of the disclosure.

As shown in fig. 2, a method for redrawing a poster of an embodiment of the present disclosure includes:

s201, layering drawing layers corresponding to the poster template;

s202, determining a drawing layer corresponding to the view to be modified;

s203, redrawing the drawing layer corresponding to the view to be modified based on the first input and the set data specification.

In S201, the drawing layers corresponding to the poster template are layered. By layering the poster template drawing layers, when a single view needs to be redrawn, only the corresponding drawing layer of the view needs to be redrawn. The exemplary principle is as follows: and (4) carrying out layering operation on the painter palette of the small program, namely cutting the poster template into a plurality of small templates and respectively rendering. Thus, if a single view needs to be redrawn, the pointer only redraws canvas of a corresponding level, and the contents drawn at other levels do not need to be perceived to have the operation at all. Due to the reduction of the drawing content, the redrawing completion time can be greatly shortened.

In S202, the drawing layer to which the view to be modified corresponds, i.e. which of the plurality of drawing layers formed in S201 for the poster template drawing layer hierarchy corresponds to the view to be modified, is determined.

In S203, redrawing the drawing layer corresponding to the view to be modified based on the first input and the set data specification. That is, the view to be modified is redrawn on the drawing layer corresponding to the view, and the drawing process is performed based on the first input and the set data specification. For example, if the first input indicates to re-edit the text in the view, in S203, the drawing layer corresponding to the view to be modified is re-drawn based on the edited text content and the set data specification, and the edited text content is updated to the view.

It will be appreciated that a variety of suitable layering methods may be used to layer the corresponding rendered layers of the poster template. The disclosed embodiments provide an exemplary layering method, which will be described below in conjunction with fig. 3 and 4.

Fig. 3 is a flow diagram of a method for layering the rendered layers of a poster template according to an embodiment of the disclosure.

As shown in fig. 3, a method for layering the drawn layers of a poster template of an embodiment of the present disclosure includes:

s301, setting a separate drawing layer for the view to be modified;

s302, dividing the background layer of the poster template into a top layer and a bottom layer.

In S301, an operation layer is separately created for the view to be updated, which is equivalent to cutting out the view to be updated from the poster template, drawing the view on a separate level, and then only redrawing the operation layer for subsequent modification.

In S302, the background layer of the poster template is divided into a top layer and a bottom layer. The three-layer type division mode draws the original layer higher than the updated view to the top layer and draws the original layer lower than the updated view to the bottom layer each time, and the layered scheme can reasonably avoid the visual problem caused by uncontrollable drawing time in a mode of adjusting the drawing sequence. For example, if the newly switched view is higher than the original level, it is drawn up from the bottom level, and if the newly switched view is lower than the original level, it is drawn down from the top level. And the effect similar to seamless switching can be achieved by using the visual residual before the drawing is finished.

In the embodiment of the present disclosure, the layering a drawing layer of a poster template by the above-mentioned exemplary layering method, in this embodiment, redrawing the drawing layer corresponding to the view to be modified based on the first input and the set data specification includes:

drawing the modified view on the separate drawing layer;

determining the level of the modified view and other views in the poster template;

adding the modified view to the top layer if the modified view is at a higher level than other views in the poster template;

adding the modified view to the bottom layer if the modified view is at a lower level than other views in the poster template.

Fig. 4 is a flow diagram of a method for layering the rendered layers of a poster template according to an embodiment of the disclosure.

As shown in fig. 4, in an implementation manner of an embodiment of the present disclosure, the method for layering the drawing layer corresponding to the poster template may further include:

s401, providing a top layer operation layer, wherein the top layer operation layer is located at the topmost layer of the drawing layer of the poster template, and the top layer operation layer is configured to respond to the selection of the user for the view in the poster template, provide a selection frame for the selected view, mark the position of the selected view, and receive the first input through the frame.

The problem of frequent refreshing caused by frequent update operations on the same view can be solved by providing a top operation layer. The principle is as follows: the drawing layer of the poster template is divided into three canvases (a single layer, a top layer and a bottom layer), and a front canvas layer (namely a top layer operation layer) is also created, is positioned at the topmost layer of the whole drawing layer and is bound with various finger touch events. When a user touch event occurs, the front canvas layer will draw a selection box at the selected view position to mark the selected view position. Meanwhile, icons for zooming and deleting are provided on the selection frame. When the touch event of the user is monitored to occur in the zoom icon, the zoom operation is performed, and in the delete icon, the view is deleted. In addition, if the operation is a dragging operation, the view is dragged, if the operation is a clicking operation, the view at the corresponding position in the process of clicking is clicked (if the view is not available, the view is deselected), or when a plurality of views are overlapped at the same position, the selected view can be switched by clicking for a plurality of times.
