It will be appreciated that the image data processing method proposed by the present application may also be performed by a picture processing program.

In some embodiments, as shown in fig. 2, an image data processing method is provided, and the method is applied to the software development kit 104 in fig. 1 for illustration, and includes the following steps:

S202, acquiring initial picture data, wherein the initial picture data is generated according to a preset format.

Specifically, the picture data is data related to a picture, and the preset format is a preset data format. The initial picture data may be picture data corresponding to a known picture, for example, may be a design draft, a designer may design a corresponding design draft by using a professional picture design tool according to a design requirement, and a user may obtain the picture data corresponding to the design draft through the picture design tool. The user can also input the picture data on the corresponding interface according to the requirement, and the terminal can receive the picture data input by the user as initial picture data.

In some embodiments, the preset format may be a particular data specification. The initial picture data may be generated by using picture data corresponding to the initial picture according to a specific data specification. The specific data specification may be a preset data specification. The software development kit may specify a specification of the incoming picture data for indicating that the picture data of the incoming software development kit needs to meet, e.g., the software development kit may specify a data specification a and specify that the picture data of the incoming software development kit should conform to the data specification a. The specific data specification may also be used to indicate the representation format of the individual picture elements, which may be JSON (JavaScript Object Notation, JS object profile) format or XML (Extensible Markup Language ) format, for example. Among them, JSON is a lightweight data exchange format. It stores and presents data in a text format that is completely independent of the programming language, based on a subset of ECMAScript (js specification formulated by the european computer institute). XML is a markup language. The mark means an information symbol which can be understood by a computer, and by such mark, articles containing various information and the like can be processed between computers. The software development kit may obtain and process initial picture data that meets a particular data specification.

S204, analyzing the initial picture data according to an analysis rule corresponding to a preset format to obtain picture elements in the initial picture data and corresponding initial attribute information.

Specifically, the initial picture data may include a picture element and corresponding initial attribute information. Picture elements refer to elements in a picture, each picture element representing a component of the picture, and the picture elements are of different kinds, such as text elements, picture elements, background elements, and the like. The attributes may include public attributes, which may include location attributes, width attributes, and height attributes, and private attributes, which may be attributes specific to a picture element, such as text attributes of a text element. The attribute information refers to related information of an attribute corresponding to the picture element, may be an attribute value corresponding to the attribute, and may include at least one of a numerical value corresponding to the width attribute, a numerical value corresponding to the height attribute, a text content of the text attribute, and a coordinate value corresponding to the coordinate attribute, for example. The initial attribute information refers to attribute information corresponding to a picture element in the initial picture data. The software development kit can analyze the initial picture data according to an analysis mode corresponding to a preset format to obtain picture elements in the initial picture data and corresponding initial attribute information. For example, assuming that the preset format of the initial picture data is JSON format, the software development kit analyzes the initial picture data according to the manner of analyzing the JSON data, so as to obtain picture elements in the initial picture data and corresponding initial attribute information.

S206, obtaining target resolution, adjusting at least one attribute information in the initial attribute information according to the target resolution to obtain target attribute information corresponding to the picture element, wherein the target attribute information is attribute information corresponding to a drawing interface, and the drawing interface is used for obtaining a target picture according to the target attribute information and the picture element.

Specifically, the target resolution is a desired resolution, and the target resolution may be a resolution specified by a user. The resolution may include a horizontal pixel count and a vertical pixel count. The target attribute information refers to attribute information obtained by adjusting the initial attribute information according to the target resolution. The initial attribute information may include a plurality of attribute information, and may include, for example, one or more of position information, width information, height information, and color information, wherein the position information, the width information, the height information are related to resolution, and the color information is not related to resolution. Therefore, when the initial attribute information is adjusted according to the target resolution, one or more attribute information related to the resolution in the initial attribute information can be adjusted to adapt to the target resolution, so that the target attribute information is obtained.

In some embodiments, at least one attribute information in the initial attribute information may be adjusted according to a size relationship of the target resolution and the resolution corresponding to the initial picture, for example, for a text element, a coordinate attribute of the text may be adjusted. For example, assuming that the resolution of the initial picture is 800×800, the target resolution is 1600×1600, and the position coordinates of the text are (2, 2), the adjusted coordinates are (4, 4).

In some embodiments, the application may send a resolution adjustment request carrying the target resolution to the software development kit, from which the software development kit may obtain the target resolution.

In some embodiments, the software development kit may call a drawing interface corresponding to each target attribute information, transfer each target attribute information into a corresponding drawing interface, draw a corresponding picture element, and obtain a view (view) corresponding to each picture element. The software development kit can generate a target picture according to the obtained views corresponding to the picture elements. Wherein the view may be drawn in memory.

In the image data processing method, the initial picture data generated according to the preset format is obtained, the initial picture data is analyzed according to the preset format to obtain the picture elements in the initial picture data and the corresponding initial attribute information, the initial attribute information is adjusted according to the obtained target resolution to obtain the target attribute information, the target attribute information is the attribute information corresponding to the drawing interface, and the corresponding drawing interface is called according to the target attribute information to obtain the target picture. Therefore, the resolution adjustment of the initial picture data is realized, the picture data with the target resolution is obtained, the picture meeting the target resolution is further obtained, and the flexibility of picture generation is improved. And because the target attribute information is the attribute information corresponding to the drawing interface, the corresponding drawing interface is automatically called for drawing, a target picture is obtained, and the generation efficiency of the picture is improved.

Currently, when a picture is to be acquired, screenshot processing can be performed, and finally, the picture is generated and stored. For the pictures taken by the screen capturing, the resolution of the screen capturing device (such as a mobile phone) is limited. If the user wants to use a picture of a larger size or browse the picture on a higher resolution device, the picture is directly enlarged, resulting in blurring of the picture information and affecting the use effect. By adopting the scheme of the embodiment of the application, the picture information can be obtained according to the actual requirement, the resolution of the picture is adjusted, and the picture with the specified resolution is obtained, so that the picture distortion caused by directly amplifying the picture is avoided.

In some embodiments, as shown in fig. 3, the method further comprises:

s302, obtaining the corresponding relation between the attribute information and the drawing interface in the operating system according to the category corresponding to the picture element.

Specifically, the category of the picture element may be text, graphics, or background. The operating system may be an Android system or an IOS system. The drawing interface refers to an interface for drawing a view corresponding to an operating system. The corresponding rendering interfaces are different for different operating systems. For example, the drawing interface corresponding to the Android system is different from the drawing interface corresponding to the IOS. The differences in the drawing interfaces may include at least one of differences in development languages, names, and methods corresponding to the drawing interfaces. Wherein the method may be a function. For example, the drawing interface corresponding to the IOS is written in the object-c language, and the drawing interface corresponding to the Android is written in the Java language. For example, when the text line spacing is set, the method corresponding to the drawing interface of the IOS system is different from the method corresponding to the drawing interface of the Android system.

In some embodiments, the types of the picture elements are different, the corresponding drawing interfaces may be different, and the software development kit may obtain the types of the picture elements, and obtain the drawing interfaces corresponding to the picture elements in the corresponding operating system according to the types of the picture elements, so as to obtain the drawing interfaces corresponding to the attribute information corresponding to the picture elements, so that efficiency of obtaining the drawing interfaces is improved. For example, the View Manager (View Manager) corresponding to the operating system may be used to manage the corresponding View object, for example, the View Manager of the picture may be used to manage the View object of the picture, and the View Manager may be used to manage the setting of the size, the link, the rounded corner, and other attributes of the picture. The view manager (ViewManager) may define element categories and the correspondence of attributes to the invoked drawing interface. The corresponding relation can be added dynamically, and a user or a developer of the software development kit can add the corresponding relation between element categories and the drawing interfaces according to requirements, for example, the corresponding relation between list elements and the drawing interfaces can be added. Wherein View is a View object in the program used for drawing, through which different manifestations of the View can be set.

In some embodiments, the correspondence between the attribute information and the drawing interface in each operating system may be integrated, so when the initial picture data is received, the operating system where the current device is located may be determined, and the correspondence between the attribute information and the drawing interface in the operating system where the current device is located may be obtained.

S304, determining a corresponding target drawing interface according to the corresponding relation between the attribute information and the drawing interface.

Specifically, the target drawing interface refers to a drawing interface corresponding to target attribute information. In general, the drawing interface corresponding to the target attribute information is consistent with the drawing interface corresponding to the initial attribute information, so the software development kit can determine the drawing interface corresponding to the initial attribute information as the target drawing interface according to the corresponding relationship between the attribute information corresponding to the picture element and the drawing interface.

S306, drawing corresponding picture elements according to the target attribute information by using a target drawing interface to obtain a target picture.

Specifically, the target picture is a picture generated after drawing a corresponding picture element according to the target attribute information. After the target drawing interfaces corresponding to the target attribute information are determined, the software development kit can transmit the target attribute information to the corresponding target drawing interfaces, so that the corresponding target drawing interfaces receive the target attribute information and draw the picture elements according to the target attribute information to obtain views of the corresponding picture elements. The software development kit can generate a target picture according to the obtained views corresponding to the picture elements. Wherein the view may be drawn in memory.

In some embodiments, the software development kit may adjust the initial attribute information according to the picture modification requirement to obtain the target attribute information. For example, the initial attribute information may be adjusted according to the specified resolution to obtain target attribute information, and the target attribute information is transferred into the target drawing interface, so that the target drawing interface receives the target attribute information, draws the picture element according to the target attribute information to obtain a view corresponding to the picture element, and the software development kit may generate a corresponding target picture according to the obtained view.

In some embodiments, the software development kit may adjust a portion of the attribute information of the initial attribute information according to the specified resolution to obtain the target attribute information. Specifically, the attribute information may include attribute information related to resolution and attribute information unrelated to resolution, and the software development kit may adjust attribute information related to resolution in the initial attribute information according to the specified resolution, and does not process attribute information unrelated to resolution in the initial attribute information, so as to obtain target attribute information, where the target attribute information includes adjusted attribute information corresponding to the initial attribute information and attribute information not adjusted.

In some embodiments, the software development kit may obtain the specified resolution from the application. Specifically, the application program may send a resolution adjustment request for performing resolution adjustment on the known picture to the software development kit, where the resolution adjustment request may carry a specified resolution. The software development tool may include retrieving the specified resolution from the resolution adjustment request. The specified resolution may be user-entered, for example, when the user needs to adjust the resolution of the picture, a target resolution may be entered on the terminal, which receives the target resolution.

In the image data processing method, the corresponding relation between the attribute information and the drawing interface in the operating system is obtained according to the category of the picture element, the corresponding target drawing interface is determined according to the corresponding relation between the attribute information and the drawing interface, and the corresponding picture element is drawn according to the initial attribute information by utilizing the target drawing interface, so that the target picture is obtained. Therefore, the picture can be automatically drawn according to the initial picture data, and the efficiency is high. And the corresponding relation between attribute information and the drawing interfaces in the operating system can be obtained according to the types of the picture elements, so that the corresponding drawing interfaces are obtained, and the flexibility of picture generation is improved.

In some embodiments, step S202 obtains initial picture data, including: the method comprises the steps of obtaining initial picture data, wherein the initial picture data comprises element objects corresponding to picture elements, the element objects are generated according to initial attribute information and the corresponding picture elements, and the element objects comprise one or more key value pairs formed according to initial attribute identifiers and attribute values in the initial attribute information.

Specifically, the initial picture data may include an element object corresponding to a picture element, where the element object may be generated according to the initial attribute information and the corresponding picture element, and one picture element may correspond to one element object. The element object comprises one or more key value pairs formed according to the initial attribute identification and the attribute value in the initial attribute information. The initial attribute identification is used to identify the attribute. The attribute value refers to a value to which the attribute corresponds. For example, a text element may correspond to a width attribute value, a height attribute value, a color attribute value, and the like, and for an element object to which the text element corresponds, the attribute identifications may include an attribute identification for identifying the width attribute value, an attribute identification for identifying the height attribute value, and an attribute identification for identifying the color attribute value. The key-value pair includes a key (key) and a value (value), where the key is used as an index. The initial attribute identifier is a key and the attribute value is a value in a key value pair formed by the initial attribute identifier and the attribute value.

For example, an element object corresponding to a Chinese element in a design script may be represented as { "coredinateSystemTen": "LeftTop", "elementType": "Text", "height":10, "width" 60, "horizontal margin" 74, "vertical margin" 207, "printProps" 88, "textContent" ABC "," textColor "88" Text F8FA "," granularity "center", "textWeight" wherein "codedinateStyle" is represented by the upper left coordinate system description, "elementary type" is represented by the Text element, "height" 10, "width" 60 is represented by the width of the relative design script, "horizontal margin" 74, "vertical margin" 207 "represents the upper left corner of the element in the upper left coordinate system, the Text program" 88 "is represented by the Text element, such as" Text size "88" is represented by the size "Text" is represented by the Text "color" 7 "color" is represented by the upper left coordinate system, and "Text color" Text "88" is represented by the Text color "RGB" is represented by the Text color "Text" 7 "Text color" is represented by the upper left corner "Text" color "FA" Text "" Text. Wherein the content around the colon constitutes a key-value pair, e.g. "height" 10 "is a key-value pair, where" height "is a key and" 10 "is a value.

Step S302 is to obtain the corresponding relationship between the attribute information and the drawing interface in the operating system according to the category corresponding to the picture element, including: and acquiring the corresponding relation between the attribute identifier and the drawing interface in the operating system according to the category corresponding to the element object.

Specifically, since the element object is generated according to the initial attribute information and the corresponding picture element, the category corresponding to the element object refers to the category of the picture element.

In some embodiments, a key-value pair consisting of a category identification and a corresponding attribute value may be included in the element object. Wherein the category identification is used to identify the category of the picture element. For example, for an element object corresponding to a text element, a category identification for identifying the text element and a key value pair consisting of the corresponding text category may be included. The software development kit can acquire category identifiers from the element objects, acquire corresponding attribute values, namely element categories, according to the category identifiers, and acquire the corresponding relations between the attribute identifiers in the element objects corresponding to the picture elements and the drawing interfaces in the operating system according to the acquired element categories.

Step S304 is to determine a corresponding target drawing interface according to the corresponding relationship between the attribute information and the drawing interface, including: and taking keys in each key value pair as initial attribute identifiers, and obtaining corresponding drawing interfaces according to the corresponding relation between the attribute identifiers and the drawing interfaces to serve as target drawing interfaces.

Specifically, the software development kit may obtain each key value pair in the element object corresponding to the picture element, take the key in each key value pair as an initial attribute identifier, and obtain the drawing interface corresponding to the initial attribute identifier according to the corresponding relationship between the attribute identifier and the drawing interface, and use the drawing interface as the target drawing interface corresponding to the target attribute information.

In the above embodiment, the obtained initial picture data includes an element object corresponding to the picture element, and the element object is generated according to the picture element and the corresponding initial attribute information, where the element object includes one or more key value pairs formed according to the initial attribute identifier and the attribute value in the initial attribute information. Therefore, the acquired picture data has a uniform data format, when a picture needs to be generated, the software development kit can be called by generating the picture data according to the data corresponding to the picture and the uniform data format, so that the picture is generated without processing a complicated picture drawing process, and the picture generation efficiency is improved.

In some embodiments, step S202 of acquiring the initial picture data includes: receiving a resolution adjustment request for adjusting the resolution of the initial picture, and responding to the resolution adjustment request to acquire initial picture data corresponding to the initial picture, wherein the resolution adjustment request carries target resolution.

Specifically, the initial picture is a generated picture, for example, when one or more pictures are displayed on the terminal, and when the user needs to zoom in on the picture, the user may request to adjust the resolution of the picture by clicking a "picture zoom in" button. The resolution adjustment request is used for requesting adjustment of the resolution corresponding to the initial picture. The target resolution is a desired resolution, which may be a user-specified resolution. The resolution may include a horizontal pixel count and a vertical pixel count.

In some embodiments, the resolution adjustment request may further carry initial picture data corresponding to the initial picture, for example, the application program may send a resolution adjustment request carrying the target resolution and the initial picture data to a software development kit, and the software development kit receives the resolution adjustment request and obtains the target resolution and the initial picture data in the resolution adjustment request.

In some embodiments, the resolution adjustment request may further carry an initial picture identifier corresponding to the initial picture, and the software development kit may obtain the initial picture identifier in the resolution adjustment request, and obtain initial picture data corresponding to the initial picture according to the initial picture identifier.

In some embodiments, the resolution adjustment request may be sent by an application. Specifically, when the resolution needs to be adjusted, for example, when receiving a related operation of adjusting the resolution by the user, the application program may call a corresponding interface of the software development kit, send a resolution adjustment request carrying the target resolution to the software development kit, and transfer the target resolution into the corresponding interface.

In the above embodiment, by receiving a resolution adjustment request carrying a target resolution for adjusting the resolution of the initial picture, the initial attribute information may be adjusted according to the target resolution to obtain the target attribute information, and the target drawing interface is utilized to draw the corresponding picture data according to the obtained target attribute information, where the obtained target picture is identical to the element of the picture corresponding to the initial attribute information, so as to implement the change of the resolution of the picture corresponding to the initial attribute information. Therefore, the resolution of the picture can be adjusted according to actual requirements, and the picture with the specified resolution is obtained, so that the picture is prevented from being directly amplified, and the picture is prevented from being distorted.

In some embodiments, as shown in fig. 4, step S206 is to obtain a target resolution, and adjust at least one attribute information in the initial attribute information according to the target resolution, where obtaining the target attribute information includes:

S402, determining first attribute information and second attribute information in the initial attribute information, wherein the first attribute information is attribute information related to resolution, and the second attribute information is attribute information unrelated to resolution.

Specifically, the initial attribute information may include attribute information related to resolution, and may further include attribute information unrelated to resolution. The attribute information related to the resolution may be coordinate information, length information, width information, or the like, and the attribute information unrelated to the resolution may be color information, font type, or the like. Accordingly, attribute information related to resolution in the initial attribute information can be identified as first attribute information; to identify attribute information, which is independent of resolution, in the initial attribute information as second attribute information.

In some embodiments, the software development kit may be preset with a resolution-related attribute, and the resolution-related attribute information may be determined according to the resolution-related attribute. The software development kit can compare the corresponding attribute with the specified attribute related to the resolution according to the attribute corresponding to each attribute information in the initial attribute information, determine whether the corresponding attribute is related to the resolution, and further determine whether the attribute information corresponding to the attribute is the attribute information related to the resolution. Thereby separating each attribute information corresponding to the initial attribute information into attribute information related to resolution and attribute information unrelated to resolution.

S404, obtaining target resolution, and adjusting the first attribute information according to the target resolution to obtain the adjusted attribute information.

Specifically, the first attribute information refers to attribute information related to resolution, and the software development kit can adjust the first attribute information according to the target resolution to obtain the adjusted attribute information. For example, the software development kit may adjust the value corresponding to the first attribute information according to the magnitude relation between the target resolution and the value corresponding to the first attribute information, for example, may zoom in or zoom out the value corresponding to the first attribute information.

And S406, taking the adjusted attribute information and the second attribute information as target attribute information.

Specifically, the second attribute information refers to attribute information that is independent of resolution, that is, data information that does not need to be adjusted according to the target resolution. The adjusted attribute information and the second attribute information may be regarded as target attribute information, i.e., the target attribute information may include the attribute information adjusted according to the target resolution and the second attribute information.

In the above embodiment, the adjustment of the attribute information related to the resolution in the target attribute information according to the target resolution may implement the enlargement or reduction of the picture data before the generation of the picture, so that the picture data may be changed according to the actual requirement, and thus the distortion of the generated picture after the enlargement may be avoided.

In some embodiments, as shown in fig. 5, step S206 is to obtain a target resolution, adjust at least one attribute information in the initial attribute information according to the target resolution, and obtain target attribute information, including:

s502, obtaining target resolution, and obtaining a target scaling factor according to the target resolution and the resolution corresponding to the initial picture.

Specifically, the target scaling factor may be obtained according to the number of horizontal pixels and the number of vertical pixels respectively corresponding to the target resolution and the resolution corresponding to the initial picture. The horizontal scaling factor can be obtained by calculating the ratio of the number of horizontal pixels corresponding to the target resolution to the number of horizontal pixels of the resolution corresponding to the initial picture; the vertical scaling factor may be obtained by calculating the ratio of the number of vertical pixels corresponding to the target resolution to the number of vertical pixels of the resolution corresponding to the initial picture. The smaller of the horizontal scaling factor and the vertical scaling factor, which corresponds to the value, may be taken as the target scaling factor. For example, if the target resolution is 200×200 and the resolution corresponding to the initial picture is 100×100, the horizontal scaling factor and the vertical scaling factor are both 2, and thus the target scaling factor is 2; if the target resolution is 150×200 and the resolution corresponding to the initial picture is 100×100, the horizontal scaling factor is 1.5 and the vertical scaling factor is 2, and thus the target scaling factor may be 1.5.

S504, scaling at least one attribute information in the initial attribute information according to the target scaling factor to obtain target attribute information.

Specifically, zooming refers to zooming in or out. The software development kit may scale the resolution-related attribute information in the initial attribute information according to a target scaling factor. When the target scaling factor is greater than 1, the software development kit can correspondingly amplify attribute information related to resolution in the initial attribute information according to the target scaling factor; when the target scaling factor is smaller than 1, the software development kit can correspondingly reduce the attribute information related to the resolution in the initial attribute information according to the target scaling factor.

In the above embodiment, the target scaling factor is obtained by the target resolution and the resolution corresponding to the initial picture, and at least one attribute information in the initial attribute information is scaled by the target scaling factor, so that the picture data can be changed according to the actual requirement, and distortion of the generated picture after amplification can be avoided. When the attribute information is scaled by selecting a smaller scaling factor from the vertical scaling factor and the horizontal scaling factor as the target scaling factor, the attribute information can be scaled in the same scale by the scaling factor, so that the deformation of the picture generated according to the target attribute information is avoided.

The system interfaces of different system drawing font sizes are inconsistent, but the format parsing layer can adapt to the interface differences of different systems, so that the same piece of data can generate views with the same font size. Likewise, other contents, such as text elements, coordinates, picture links or picture fillets of picture elements can be drawn by using corresponding drawing interfaces corresponding to the corresponding systems.

In some embodiments, the application program may send the specified resolution to the software development tool, and after the format parsing layer obtains the category of the picture element and the initial attribute information, the format parsing layer may adjust the initial attribute information according to the specified resolution, and call the drawing interface to draw according to the adjusted attribute information, so as to obtain a picture with the specified resolution.

Therefore, when the picture needs to be generated, the software development kit can be called by generating the picture data according to the data specification by the data corresponding to the picture, so that the picture is generated without processing a complicated picture drawing process, and the picture generation efficiency is improved.

Specifically, the software development kit may return the target picture to the application program in a callback manner.

In some embodiments, the target picture may be a picture binary stream, a picture local file, or a network picture.
