This disclosure relates to the field of computer application technology, and in particular to a picture generation method, apparatus and storage medium.
With people's increasing awareness of environmental protection and the acceleration of informatization construction, the concept of paperless office has gradually been applied in our daily life. The way in which signs such as house signs and table signs are used has also undergone tremendous changes. For example, companies, enterprises and so on have gradually replaced paper signs with electronic signs. Contents of the electronic signs are usually displayed in the form of pictures. These pictures are generally generated by invoking third-party drawing tools. However, the third-party drawing tools are usually unable to be integrated with application services, so the application services are facing the need of integrating picture generation functions.
Besides, there are also solutions in which pictures are drawn directly in application services by using a Graphics2D tool in the Java native class. However, this kind of drawing tool is not targeted or is quite similar to a sketchpad tool, so a user has to redraw all elements of the pictures every time, which leads to a low drawing efficiency.

The above and other features and advantages of this disclosure will become clearer after detailed description of the specific embodiments with reference to the drawings.
In order that one having ordinary skills in the art can better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this disclosure will be described clearly and completely as follows with reference to the drawings.
It should be noted that terms such as “first” and “second” in the description, the Claims and the drawings of this disclosure are used to distinguish similar objects rather than necessarily describe a specific order or sequence. It should be understood that such numbers may be exchanged where appropriate, so that the embodiments of this disclosure described herein can be implemented in an order other than those illustrated or described herein.
It should also be understood that the term “comprise” indicates the existence of the described features, wholes, steps, operations, elements and/or components, but does not exclude the existence or addition of one or more other features, wholes, steps, operations, elements and/or components.
With the development of paperless office and the advancement of informatization construction, companies, enterprises and so on are having an increasing demand for content customization and custom control of electronic signs. In related arts, contents of the electronic signs are usually displayed in the form of pictures. In some solutions, these pictures are generally generated by invoking third-party drawing tools such as PhotoShop, ProcessOn, etc. Although such drawing tools can both draw complicated pictures and support generation of various pictures, the drawing procedure is so cumbersome that manual operations are required repeatedly to complete the drawing of a large batch of pictures. Moreover, such third-party drawing tools are usually unable to be integrated with application services.
In other solutions, pictures may be drawn by using Java-based third-party drawing tools (e.g., drawing tools such as JViews, Edraw, etc.). However, such drawing tools are usually not open source and generally independent, so it is still difficult to integrate these tools with application services.
Besides, pictures may also be drawn directly in the application services by using a Graphics2D tool in the Java native class. However, this kind of drawing tool is quite similar to a sketchpad tool, so a user has to redraw all elements in the pictures every time, which leads to a low drawing efficiency.
To solve the above problems, the embodiments of this disclosure provide a picture generation method which achieves drawing of a target picture by parsing content elements for describing design contents of the target picture. As compared with an existing picture generation approach in the related arts, the method according to the embodiments of this disclosure improves the drawing efficiency.
In step 110, a plurality of content elements contained in a design of a target picture are acquired. The content elements have respective attribute information.
A content element, as used herein, may refer to an individual constituent part that can independently describe a specific content of a specific area in a picture. Exemplarily, examples of a content element may be text (e.g., strings), picture, QR code (the content of QR codes is usually in a text form), table (e.g., including a head and a body, as well as text contained in cells thereof) etc. Attribute information of a content element may comprise one or more of type, position, color, size, font, orientation and so on. In some embodiments, attribute information that are shared by content elements may comprise for example x-axis coordinate and y-axis coordinate for indicating a position within a picture, the width and height of an occupied region, whether a border is contained, or the like. Additionally, attribute information of a text element may comprise font, font size, color, whether it is in italic, whether it is in bold, whether it is underlined, etc. Attribute information of a table element may comprise row height and column width of the head, row height and column width of the body, and attributes of the text in the head and body are the same as those of the text element.
In some embodiments, the content elements may further comprise a plurality of content sub-elements.
In such an embodiment, the acquisition of the content elements may be performed by obtaining the content elements as a whole. Additionally or optionally, the acquisition of the content elements to may also be performed by acquiring each content sub-element (together with its attribute information) of the content elements separately.
Since the content sub-elements obtained by splitting the content elements are more likely to correspond to basic graphics supported by various drawing tools, to acquire each content sub-element separately may accelerate the speed of element parsing in the subsequent procedure and thus improve the drawing efficiency.
In some embodiments, content elements contained in a target picture design may also be obtained by acquiring a template file and parsing the template file. Each template file may correspond to a picture design, and be used to describe a specific combination of a set of specific content elements in the picture design. A template file may describe a plurality of content elements contained in the target picture and their manifestations in the target picture, such as layout, color scheme, or other variables that can be applied to the content elements.
The template file may be preset, for example, the template file may be a default template file of a designer system for picture design. Alternatively or additionally, a template file may also be generated dynamically based on a user need. Exemplarily, the template file may be generated by a user using for example WebUI framework. A file format of a template file may be a file format that can be parsed, e.g., extensible markup language (XML) format, JSON format and so on.
In some embodiments, a template corresponding to the template file may be created or modified by a designer. For example, the size of the template and the attributes of elements in the template, e.g., position, color, font, etc., may be modified. The template created by the designer may be exported in XML or JSON format.
Creation or modification f a template with a designer allows a user to intuitively view a designed picture that is relatively close to a picture with final effect.
Returning to
In some embodiments, the graphic elements may be basic graphics drawn by a drawing tool. As such, graphic elements corresponding to content elements may be obtained in accordance with the correspondence relations between the content elements and the basic graphics.
The associated graphic parameters of the graphic elements may be parameters for enabling the drawn graphic elements to be presented in a desired way. The graphic parameters may be generated based on the attribute information of the content elements. Exemplarily, in drawing the content elements, the graphic parameters are used to set drawing parameters of the drawing tool such that the drawn graphics and the content elements have the same attributes.
In an example, when a content element is a text element, since the text element is a graphic that can be drawn, corresponding text graphic can be obtained directly by parsing the text element, and the attribute information of the text element can be correspondingly translated into graphic parameters of the text graphic. For example, the color attribute of the text element may be used as a color parameter of the corresponding text graphic for setting a color value of the text graphic in drawing the text graph.
In another example, when the content element is a table element, since the table element do not directly correspond to a graphic element, it may be parsed and split into a plurality of text graphics, and position parameters relating to position may be generated based on position attributes of the table elements and relative position relationships between the text graphics for respective text graphics. The position parameter may indicate the relative displacement of position coordinates among multiple text graphics, or it may be the absolute position coordinates of the multiple text graphics. The position parameter of each text graphic may indicate a position where the corresponding text graphic is drawn, thereby creating the table elements.
In step 130, the graphic elements are drawn according to the associated graphic parameters to obtain content element pictures for respective content elements. Here, a content element picture is a picture that expresses content described by a respective content element in a graphical representation.
The one or more graphic elements may be drawn using a drawing tool. In an example, when the content element is a text element, the corresponding text graphic and associated color parameter, position parameter, font parameter, font size parameter, etc. can be obtained by parsing the text element. According to the obtained graphic parameters, the drawing tool may set the color value, position coordinates, font and font size for the text graphic so as to draw the text graphic. Optionally, when the text element comprises different text strings in different positions, two corresponding text graphics and associated graphic parameters can be obtained by parsing the text element. In this scenario, the drawing tool draws the text graphics according to respective graphic parameters to complete drawing of the text element and obtain a text element picture, i.e., pictorialized text. In another example, when the content element is a table element, a plurality of text graphics and associated graphic parameters can be obtained by parsing the table elements. The corresponding text graphics may be drawn using the drawing tool according to the graphic parameters in light of the order of respective cells in the table to complete drawing of the table element and obtain a table element picture, i.e., a pictorialized table.
Optionally, layers may also be set for the content elements. In such an embodiment, each content element is drawn in light of the order of the layers of the content elements.
Optionally, the graphic elements may be drawn using a drawing tool of Java.awt package in Java Development Kit (JDK). The drawing tool is for example Graphics2D in Java.awt package. Graphics2D may draw various 2D basic graphics, including line segment, polyline, polygon, text, etc.
For example, the following codes may be used to invoke Graphics2D in order to set a background color.
In this embodiment, since Graphics2D is a class in native JDK, it has a good cross-platform performance. Moreover, the Graphics2D tool can support the drawing of various basic graphics, so it has a strong functionality.
In step 140, the obtained content element pictures are combined to generate the target picture. The drawing tool may draw the content elements on a canvas. After drawing are completed for all content elements, canvases on which the content elements are drawn, i.e., canvases containing the content element pictures, may be combined to generate the target picture.
According to the embodiments of this disclosure, descriptive contents of a target picture design are split into content elements and the content elements are parsed to obtain graphic elements so as to perform picture drawing, thereby enabling automatic drawing. As compared with the picture generation approach in which pictures are drawn manually by a user, the drawing efficiency is improved.
In some embodiments, after the target picture is generated, further processing on the generated picture may also be performed as desired. In such embodiments, the generated picture may be processed as a preliminary picture to obtain a processed picture.
As shown in
Optionally, in step 511, the configuration information may be obtained by parsing a template file. Continuously referring to
Additionally or alternatively, the configuration information of a picture may be acquired in other manners, e.g., by inputting in a user interface by a user, or by parsing a configuration file separate from the template file.
The graphic transformation information may be used to control basic geometric transformation of a picture generated based on content elements, including translation, rotation, scaling and so on. By containing configuration information about graphic transformation, the presentation of pictures can be flexibly changed so as to better adapt to a desired presentation effect.
The format conversion information may be used to control conversion of the data format of a picture generated based on the content elements. For example, in a scenario where the target picture is to be displayed on an EPD device, since different EPD devices require different data formats, it may be required to convert the data format according to requirements of the EPD devices. In such a scenario, the configuration information may comprise EPD conversion information for indicating a data format required by an
EPD device for displaying the target picture.
The file path is used to indicate a saving (including e.g., cache) path of a picture. In some embodiments, after picture drawing and processing are completed, the generated target picture may be pushed to a terminal device. During the drawing and pushing, the picture may be transferred in the form of Base64 encoding or binary stream. The picture information will not be saved additionally if a save setting is not enabled. In such an embodiment, a user may be provided with an option of enabling a save setting and in turn a file path for saving a picture file for the picture. In this way, after the user enables the save setting, the user can save a drawn picture so as to preview an effect of the picture. If he/she is not satisfied with the picture, the picture drawing and pushing may be carried out again.
In step 610, it is determined whether the configuration information contains graphic transformation information. In step 620, in response to the configuration information containing graphic transformation information, graphic transformation, e.g., geometric graphic transformation, is performed on the picture. The graphic transformation may be realized by using a graphic processing tool. The graphic processing tool is for example BufferedImage in the Java.awt package. BufferedImage is an image class with a buffer, and its major function is to load an image to a memory so as to allow convenient operation of the image. BufferedImage may be used to perform image transformation operations such as image zooming, image rotation, image transparency change and so on.
For example, rotation of a preliminary picture may be realized by the following codes.
In step 630, it is determined whether the configuration information contains format conversion information. In step 640, in response to the configuration information containing format conversion information, format conversion is performed on the picture. A format conversion service may be invoked via a target interface to perform format conversion on the picture. In step 650, a target picture processed according to the configuration information (e.g., graphic transformation information or format conversion information) is obtained.
Optionally, in a scenario where the target picture is to be displayed using an EPD device, different EPD conversions may be required, so the configuration information may contain EPD conversion information. In this case, by defining a target interface, a corresponding EPD conversion service may be invoked from the target interface to perform EPD conversion on the preliminary picture, thereby obtaining the target picture.
For example, the target interface may be defined by the following codes.
It would be understood that the procedures of graphic transformation and format conversion as shown in
Optionally, in step 660, it may be determined whether the picture is to be saved. In step 670, in response to determination that the picture is to be saved, a file path for indicating a cache/saving path of the picture may be extracted from the configuration information, and a picture file of the target picture is saved according to the file path.
Alternatively, in further embodiments, the file path may be used to indicate a storage path of a target service, or an invoking path of the target service. The target service is configured to implement the picture generation method in this disclosure.
Optionally, when multiple drawing instructions are received, according to the number of threads in the configuration information that indicates the number of pictures that can be generated at the same time, multi-thread processing may be enabled through a thread pool to process the multiple drawing instructions simultaneously in multiple threads, thereby generating pictures simultaneously in multiple threads. By supporting multi-thread drawing, the goal of concurrent processing is achieved and the efficiency of picture generation is improved.
In some embodiments, the picture generation method according to the embodiments of this disclosure may also comprise rendering a target object. The target object may be a content element or a picture.
After drawing of the content elements is completed, in step 710, it is determined whether the content elements are to be rendered. In some embodiments, a content element may comprise a renderer attribute value, and it is determined whether the content element is to be rendered based on presence or absence of the renderer attribute value therein.
In step 720, in response to determining that one or more of the content element to be rendered, a rendering strategy set for the one or more content elements is acquired. The rendering strategy may be set based on a business need of a business for which the target picture is utilized. The rendering strategy may be used to determine how the content elements are presented. Rendering strategies may be specified for the content elements respectively, thereby realizing customization of the rendering of the content elements.
In step 730, the one or more content elements are redrawn according to a respective set rendering strategy to obtain rendered content element pictures. Exemplarily, a renderer corresponding to the content elements may be loaded to render the content elements according to the rendering strategy. The renderer may be employed to expand or change the presentation of elements.
In an example, the business need may comprise changing the color of a cell in a table of a target picture according to content of a digit in the cell. For example, if the digit in the cell is smaller than 10, the cell is displayed in red; if the digit is greater than 10, the cell is displayed in green. For this business need, a corresponding rendering strategy for the table element may be specified in the renderer, i.e., comparing the digit in the cell with 10, and if the digit is smaller than 10, setting the color attribute or color parameter of the cell red; and if the digit is greater than 10, setting the color attribute or color parameter of the cell green. In another example, the business need may be that different colors are required to be applied for different rows in the table of the target picture, or a specific color is required to be applied thereon when a column of the table has a certain value, and so on. For this business need, the rendering strategy may be specified as that setting different color attributes or color parameters for cells in adjacent rows of the table, or comparing the value of a cell in the column of the table with a preset value, and if they are equal, setting the color attribute or color parameter of the cell to be a specific value.
In such an embodiment, in combining the obtained content element pictures to generate the target picture, the content element pictures comprise the rendered content element pictures.
Optionally, after the content elements are drawn, one or more of the content element pictures may be rendered correspondingly.
According to the method in the embodiments of this disclosure, after the content element pictures are combined to generate a preliminary picture, the preliminary picture may be rendered so as to expand or change the presentation of one or some content elements. Exemplarily, a renderer corresponding to the target picture may be loaded to render the preliminary picture.
According to this embodiment, the target object may be rendered by using the renderer after being drawn, which enables secondary processing of the picture contents based on different business needs. Since the drawing and rendering of the target object are performed separately, the business logic processing for rendering is decoupled from the picture drawing procedure, which further enhances the flexibility of the drawing of pictures such that it can better adapt to the user's needs.
Optionally, when it is determined that the content elements are to be rendered, the content elements in the target picture may be rendered by inheriting a Section class and invoking from a first interface a render. For example, when a user desires to fill different rows of the table with different colors, the first interface (defined as SectionRenderer) may be developed in a customized manner.
Exemplarily, the first interface may be defined by the following codes.
After that, the renderer may be invoked via the first interface to render the graphic elements in the target picture.
Optionally, in the present disclose, elements may also be customized by inheriting the Section class and implementing a draw method. Customization of an element is namely to declare a type of an element, including the definition of the element, which attributes are comprised in the element and so on, and a customized element needs to inherent a base class of content element. For example, customization of a triangle content element needs to declare the definition of a triangle, including attribute information such as the length attribute, color attribute, position attribute, etc. of each side, and the inherited base class is for example the Section class. In this way, after the customized element is added into a template, during the parsing of the template file, it may be determined whether the triangle element inherits Section class in the declaration of customized element. If yes, it will be parsed as a content element and finally drawn on the picture.
In some embodiment, the method according to the embodiments of this disclosure may be implemented by an electronic device serving as a terminal device. In further embodiments, the method according to the embodiments of this disclosure may also be implemented by a service running on a server independently.
In step 810, the client receives a request for generation of a target picture. In an embodiment, the client may acquire from the request a template file describing a target picture design. Alternatively or additionally, the client may also provide, in response to the request, a designer for picture design to a user so as to enable the user to customize a desired target picture template. The designer may interact with the user via a graphic user interface so that the user can intuitively complete the target picture design. In such an embodiment, after the user completes the design of the picture, the designer may export the created template as a template file in xml or json format for example. Optionally, the user may further modify the template via the graphic user interface of the designer. Alternatively or additionally, the user may also modify the template by directly modifying the template file.
In step 820, the client invokes a picture generation service at the service side via an interface. The client may transfer the template file for the target picture design to the server via interface invoking.
In step 830, the service implements, in response to service invoking, the picture generation method according to the embodiments of this disclosure to generate the target picture.
In step 840, the service returns the target picture to the client.
Optionally, a target service may be built according to the picture generation method based on springboot framework to achieve encapsulation of the picture generation function. The target service may be in the form of a service interface, or in the form of a dependency.
Optionally, an independent running service may be built according to the picture generation method based on springboot framework, and a drawing interface is provided to the outside in Controller to enable other application services to invoke the picture generation method via the drawing interface, thereby achieving automatic generation of pictures without a visualization interface.
The target service may also be built according to the picture generation method based on springboot framework, and then packed into a jar package which is used as a dependency to provide drawing support for other projects.
In these embodiments, by utilizing the springboot framework for project construction, the target service can be realized as an independently running service or a dependency, which facilitates the integration of the solution according to the embodiments of this disclosure with other applications or application services.

Therefore, references to specific functional units are only regarded as references to appropriate units for providing the described functionality, but do not indicate a strict logical or physical structure or organization. Therefore, the present application may be implemented in a single unit or distributed physically and functionally between different units and circuits.
It should be understood that the serial number of the processes do not necessarily imply the order of execution. The order of execution of the processes should be determined based on their functions and inner logics. The serial number of the processes should not limit the implementation procedure of the embodiments of this disclosure in any possible way.
Although this disclosure has been described in combination with each exemplary embodiment, those skilled in the art will understand that many modifications may be made to these embodiments within the scope of the appended claims. Correspondingly, the above description is not intended to limit the scope of this disclosure in any possible way. On the contrary, the scope of this disclosure will be determined with reference to the Claims.
