With the rapid development of online education, an education editor has the advantages of convenient resource acquisition, capability of building various courseware templates according to requirements, and the like. In addition to educational editors, various multimedia files are widely employed in the educational industry to enrich teaching patterns, such as PPT courseware. However, commonly used multimedia files often require specific software to open and are not compatible with educational editors. If an existing multimedia file is to be restored in the educational editor, it is necessary to make a new production in the educational editor, resulting in a great deal of repetitive work, wasting labor costs and time costs.

The data processing method, device, electronic equipment and storage medium provided by the application aim to solve the technical problems in the prior art.

It should be noted that the following embodiments may be referred to, or combined with each other, and the description will not be repeated for the same terms, similar features, similar implementation steps, and the like in different embodiments.

Fig. 1 is a schematic view of an application environment of a data processing method provided in an embodiment of the present application, where the application environment includes a terminal device 101, a target editor is installed in the terminal device, the target editor may obtain a multimedia file to be converted, parse the multimedia file to obtain each source page and a source element corresponding to the source page, then convert original element information of the source element into target element information applicable to the target editor, for each source page, create a target page corresponding to the source page in the target editor, obtain a target component corresponding to the source element, configure the target component based on the target element information of the source element, and load the target component into the target page to generate target multimedia data.

In the above application scenario, the conversion for the multimedia file is performed by the user terminal installed with the target editor, and in other application scenarios, the above conversion operation may be performed by the server. Those skilled in the art will appreciate that the above examples do not limit the application scenario of the data processing method of the present application.

The server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing cloud computing service. The terminal may be, but is not limited to, a smart phone, a tablet computer, a notebook computer, a desktop computer, etc. The terminal and the server may be directly or indirectly connected through wired or wireless communication, which is not limited herein.

Fig. 2 is a flow chart of a data processing method according to an embodiment of the present application, and as shown in fig. 2, the method is applied to a target editor, and includes:

in step 201, a multimedia file to be converted is obtained.

Specifically, the multimedia file to be converted may be a multimedia file to be imported into the target editor, and the multimedia file may be a file combining multiple media such as images, sounds, images, texts, animations, etc., and optionally, the multimedia file may be a PPT file.

Step 202, parsing the multimedia file to obtain at least one source page and source elements corresponding to each source page.

Specifically, after the multimedia file is obtained, the multimedia file is parsed to obtain at least one source page included in the multimedia file and a source element corresponding to each source page. The source page may be a page included in the multimedia file, and the PPT file is taken as an example, where one slide in the PPT file is a source page. The source elements may include various types of pictures, text, shapes, formulas, audio, video, and tables.

The parsing mode may be complete parsing, that is, the original content of the multimedia file is completely reserved during parsing; the visual part of the file, i.e. the rendered presentation form, may also be directly parsed for selective parsing, i.e. parsing the original data composition of the multimedia file is not parsed during parsing, which is not particularly limited in the embodiment of the present application.

Here, the parsed data may include a source page included in the multimedia and original page information of the source page, where the original page information may include attribute information such as width and height, background, name, etc. of the page, and animation information such as a page appearance or a departure mode; the source page can also comprise source elements and original element information of the source elements, wherein the original element information can comprise attribute information such as types, positions, colors and the like of the elements, and animation information such as dynamic effects of element display and the like.

Step 203 converts the original element information of the source element into target element information suitable for the target editor.

Specifically, since the original multimedia file can be opened only by specific software, for example, the PPT file can be opened only by WPS (office software) or Microsoft Office PowerPoint (presentation software of microsoft corporation), the data format representing the multimedia file can support only specific software. In order to restore the multimedia file in the target editor, the multimedia file needs to be converted into a data format suitable for the target editor.

After the parsing of the multimedia data is completed, at least one source page and at least one source element included in each source page can be parsed from a complete multimedia file. Converting original element information of a source element according to a preset corresponding relation to obtain corresponding target element information, wherein the target element information is information describing a target element applicable to a target editor, and the target element information can comprise attribute information such as type, position and color of the target element, animation information such as dynamic effect of target element display.

For example, when the source element is color-expressed based on HSL (Hue, saturation, and brightness), and color-expressed based on RGB (Red, green, blue) in the target editor, the color attribute HSL of the original element of the source element needs to be converted into the color attribute RGB of the target element.

Step 204, for each source page, creating a target page corresponding to the source page in the target editor, and obtaining a target component corresponding to the source element.

Specifically, after the conversion of the element is completed, the converted element needs to be further imported into the target editor. For each source page, a target page corresponding to the source page is created in the target editor, wherein the target page is a scene page built in the target editor, and page attributes of the target page, such as length, width, background and the like, can be adaptively adjusted according to the corresponding source page, or default settings of the target editor can be directly adopted, and the embodiment of the application is not limited to the foregoing.

After the creation of the target page is completed for each source page, that is, the source page is imported into the target editor, the element corresponding to the source page needs to be further imported into the target editor, and the source element can be restored through the target component corresponding to the source element. The target component may be a software entity encapsulated for a specific object and built in the target editor, and for different kinds of objects, the target component may include multiple types of pictures, texts, shapes, formulas, audio, video, tables, and the like.

Step 205, configuring a target component based on the target element information of the source element, and loading the target component into the target page to generate target multimedia data.

Specifically, the target component may include a component attribute, and by setting the component attribute of the component, an object corresponding to the component may be presented in a specific form in the target page. After the source element is converted, the obtained target element information is suitable for a target editor, so that a corresponding target component can be configured according to the target element information of the source element, and the configured target component is loaded into a target page, namely the source element can be restored through the target component.

Fig. 3 is a schematic diagram of a source element restoring process provided in this embodiment of the present application, as shown in fig. 3, where a source element in a PPT file presentation 1 is a circle, target element information of the source element includes coordinates, a circle center, a radius, a contour color, a filling pattern, and the like mapped to the circle in a target editor, a target component corresponding to the source element is a shape component, and component attributes of the target component are set according to the coordinates, the circle center, the radius, the contour color, the filling pattern, and the like in the target element information, and by loading the target component into a target page, a circle with the same size, the same contour color, the same filling pattern as the source element and the same relative position in the page can be generated in the target page, that is, restoration of the source element in the target editor is completed.

For each source page, the source elements included in each source page can be imported into the target editor based on the steps above, and then the entire multimedia file can be imported into the target editor. After the multimedia file is imported, the data correspondingly generated in the target editor is used as target multimedia data. The target multimedia data is multimedia data which is applicable to the target editor and has the same content and form as the original multimedia file.

According to the method provided by the embodiment of the application, the target element information of the source element is determined by analyzing and converting the multimedia file, the target component is configured according to the target component corresponding to the source element and the target element information of the source element, and the target component is loaded into the target page to generate the target multimedia data, so that the effective compatibility of the multimedia file and the target editor is realized, the multimedia file can be restored in the target editor without remanufacturing, a great amount of labor cost and time cost are saved, the existing multimedia file resources are fully utilized, and the reusability of the resources is improved.

As an alternative embodiment, the original element information includes at least one of original element attribute information and an original animation effect, and the original element attribute information includes at least one of an element type, an element position, an element size, and an element color.

In particular, the raw element information may include static raw element attribute information and/or dynamic raw animation effects, and the raw element attribute information may include at least one of an element type, an element position, an element size, and an element color.

The element position may be a relative position of the element in the corresponding page, the element position may be represented as coordinates, the element size may be a size of the element, such as a length and a width, and the element color may be a data format represented by the element color. Accordingly, the target element attribute information may also include at least one of an element type, an element position, an element size, and an element color.

As an alternative embodiment, when the original element information includes an element position, converting the original element information of the source element into target element information suitable for the target editor, includes:

according to a preset position conversion method, converting an original element position of a source element into a target element position suitable for a target editor, wherein the position conversion method is used for converting the original element position into the target element position suitable for the target editor.

As an alternative embodiment, when the original element information is an element size, converting the original element information of the source element into target element information suitable for the target editor includes:

And converting the original element size of the source element into a target element size suitable for a target editor according to a preset size conversion method, wherein the size conversion method comprises at least one of angle conversion, width conversion and font size conversion.

The following description will take a multimedia file as a PPT file as an example.

Since the measurement unit of the PPT file is specific, for example, the default unit is dxa units, that is, 20 times of the pixel point; EMUs (English Metric Unit, english metric units) are used to represent the width of pictures and other elements; half-points are Half-dots of font size, one dot being equal to two Half-dots. While the target editor may use different units of measure to represent the element size and coordinate location, e.g., pixels (px), importing the PPT file into the target editor requires unit scaling.

The manner of angle conversion can be as follows: target element angle = original element angle/60000; the width conversion mode can be as follows: target element width = PPT element width (editor scene width/PPT scene width); the font size scaling may be: target font size= (PPT element font size/100/72) × 914400 (editor scene width/PPT scene width).

Assuming a slide (i.e., source page) is 12192000EMUs wide by 6858000EMUs high by 1920px wide by 1080px high for the scene of the target editor, e.g., source element width 2579370EMUs, then the source element width is 2579370 x (1920/12192000) for the target editor.

Furthermore, in the case of a PPT file with a percentage of thousands of times, that is, a value representing one percent per 1000 units, that is, a corresponding ratio of 1 to 100000, a value of thousands of times is required when clipping the picture size, and the original value is divided by 1000, so as to obtain the value of the percentage.

As an alternative embodiment, when the original element information includes an element color, converting the original element information of the source element into target element information suitable for the target editor, includes:

according to a preset color conversion method, converting an original element color of a source element into a target element color suitable for a target editor, wherein the color conversion method is used for converting the original element color into the target element color suitable for the target editor.

Since the transformation of colors in the PPT file is through modification of the relevant properties of the underlying colors. For example, transparency is a color-related attribute. By changing the relevant properties, such as hsl, tint, shade, etc., the manner in which the color is presented can be changed. The color representation modes in the target editor are different, for example, color representation can be performed through formats such as Hex (hexadecimal color mode), RGBA (color space composed of RGB three channels and Alpha channels), and the like, so that the original color representation of the element in the PPT can be converted into the format supported by the target editor through a preset color conversion method. The preset color conversion method can be any conversion method conforming to the microsoft specification.

As an optional embodiment, step 204 of obtaining the target component corresponding to the source element may include:

and according to the component types, inquiring to obtain the target components corresponding to the source elements from the component library of the target editor.

Specifically, the target editor is configured with a component library including a plurality of components, each component corresponding to one component type, for example, a shape component that processes shapes, a picture component that processes pictures, a text component that processes texts, a formula component that processes formulas, a form component that processes forms, an audio component that processes audio, a video component that processes video, and the like.

Mapping the element types of the source elements according to a preset first corresponding relation, so that the component types corresponding to the element types can be obtained, wherein the first corresponding relation is the corresponding relation between the element types and the component types.

For example, when the element type is a shape, the component type corresponding to the element type is a shape component; when the element type is a picture, the component type corresponding to the element is a picture component. And then according to the component type, inquiring from a component library of the target editor to obtain the target component corresponding to the source element.

Here, the source element and the target component are in a one-to-one correspondence, that is, there is a target component corresponding to one source element. For example, the source page includes two source elements, the first source element is rectangular, the corresponding element type is shape, and there is a first shape component corresponding to the first source element; the second source element is circular and the corresponding element type is shape, there is a second shape component corresponding to the second source element.

It should be noted that if there is no component matching the source element in the component library of the target editor, the restoration of the source element in the target editor may be omitted.

As an optional embodiment, the determining, according to the element type of the source element and the preset first correspondence, the component type corresponding to the element type includes:

the method comprises the steps of determining the actual element type of a source element through attribute description of the source element, mapping the actual element type of the source element to the element type supported by a target editor, and determining the component type corresponding to the element type.

Specifically, the actual element type of the source element may be determined by analyzing and identifying the attribute description of the source element. Wherein, the attribute description of the source element may be information describing the attribute of the source element, and the actual element type of the source element may be different from the actual type of storage or representation of the source element in the computer.

Alternatively, the representation of the elements in the PPT file is not the same as the actual type, e.g., text in the PPT is also represented as a shape, so the actual type of the elements in the PPT file needs to be identified first, where it can be determined by analyzing the attribute description of the elements. For example, when "txBox (an attribute name)" in the shape attribute description of the shape element is 1, this element is represented in the form of a text box, and thus it can be determined that the actual type of the element is text. For another example, most multimedia elements are stored in the Picture in the PPT, the actual type of the element can be determined through specific attribute information of the Picture element, if the Picture element describes a file with video file and audio file, and related resources are referenced, the actual type of the Picture element can be determined to be video and audio, and on the basis, the Picture of the Picture element can be used as a cover of audio and video.

After determining the actual type of the element in the PPT file, the actual type of the element may be mapped to the element type supported by the target editor. For example, the target editor supports element types such as text, shape, audio, video, formulas, tables, etc., and the actual type of the element can be directly used as the element type to determine the corresponding component type.

As an alternative embodiment, the method further comprises:

determining a corresponding target animation effect according to the original animation effect of the source element and a preset second corresponding relation; the target animation effect is an animation effect suitable for a target editor;

configuring a target animation effect to a target component corresponding to a source element;

the original animation effect is a combination of the first original animation effect and the second original animation effect; the target animation effect is a combination of a first target animation effect and a preset target animation effect, or a combination of the first target animation effect and a second target animation effect.

Specifically, the source elements in the multimedia file include not only static attributes of color, position, size, etc., but also animation effects of appearance and/or exit. The second corresponding relation is a corresponding relation between the original animation effect and the target animation effect, and in order to restore the animation effect of the source element in the multimedia file, the original element effect of the source element can be mapped according to the preset second corresponding relation, so that the corresponding target animation effect is obtained.

Wherein the original animation effect and/or the target animation effect may be a combination of a first animation effect and a second animation effect, the first animation effect may include entering, emphasizing, exiting, emphasizing, and the like, and the second animation effect may include fading, shaping, erasing, splitting, and the like. The first animation effect is a primary effect, and the second animation effect is a secondary effect.

The first animation effect of the animation effect may include a corresponding number of second animation effects, for example, the first animation effect is an entry, and the corresponding second animation effect may be a multiple animation form of a fade entry, a shutter entry, a wipe entry, a fly-in, and the like. The first animation effect is typically a common effect that can be presented in both the multimedia file and the target editor; the second animation effect is a further refinement, which may not be rendered in the multimedia file and/or in the target editor.

Optionally, the original animation effects may include a first original animation effect and a second original animation effect, first determining a first target animation effect corresponding to the first original animation effect of the source element, then determining a second target animation effect corresponding to the second original animation effect of the source element, and finally determining a final target animation effect by combining the first target animation effect and the second target animation effect, where the final target animation effect is a combination of the first target animation effect and the preset target animation effect, or a combination of the first target animation effect and the second target animation effect.

For example, the original animation effect of the source element is entering in a desalination manner, that is, the first original animation effect is entering, the second original animation effect is fading, according to a preset corresponding relationship, the first original animation effect is mapped to obtain the first target animation effect as entering, and then the second original animation effect is mapped to obtain the second target animation effect as fading, and the final target animation effect enters in a desalination manner, that is, the combination of the first target animation effect and the second target animation effect.

After the target animation effect is confirmed, the target animation effect is configured to the target component, where the target animation effect may be given to the target component as an attribute, or a component identifier corresponding to the target component may be added to the target animation effect.

It should be noted that if there is no second target animation effect corresponding to the second original animation effect of the source element in the target editor, the processing may be performed by using a preset target animation effect, and the final target animation effect is a combination of the first target animation effect and the preset target animation effect.

For example, the original animation effects include a first original animation effect being an entry, a second original animation effect being a wipe-type entry, the first original animation effect being mapped to a first target animation effect being an entry, the second original animation effect not being a corresponding second target animation effect, and a preset target animation effect, such as a fade-type entry, being adopted at this time, the wipe-type entry of the original animation effect being unified to a target animation effect fade-type entry.

Similarly, when the original animation effect is a stepwise exit, the target animation effect can uniformly adopt a desalination type exit; when the original animation effect is changed font type emphasis, the target animation effect can uniformly adopt impulse type emphasis. The processing mode can meet the requirement that the target editor can convert the animation effect of the main stream, and reduce the cost of developing individual and numerous special animation effects.

As an alternative embodiment, the original animation effect of the source element needs to be predetermined, and then the target animation effect corresponding to the original animation effect is determined according to the original animation effect of the source element; the original animation effect can be obtained by analyzing animation parameters of the source element.

For some original animation effects, it is difficult to confirm their animation classification, which can be obtained by analyzing the animation parameters of the source element. Taking a PPT file as an example, the animation effect of a source element can be identified by analyzing the animation parameters of the source element, for example, the animation parameters of the source element include the element height ppt_h= [0, '#ppt_h' ] and the element width ppt_w= [0, '#ppt_w' ] fields, the width and height of the element when the element appears can be analyzed to be 0, and then the element becomes the normal width and height of the element, so that the process is known to be a scaling action, and the scaling animation of the animation appears is obtained. If angular rotation is also included, then the animation is flipped from far to near. After the original animation effect of the source element is obtained through analysis, determining a target animation effect corresponding to the original animation effect according to the original animation effect of the source element by the method.

According to the method and the device, the corresponding target animation effect is determined according to the original animation effect of the source element and the preset second corresponding relation, and the target animation effect is configured to the target component corresponding to the source element, so that the restoration of the animation effect of the source element in the multimedia file is realized, and the restoration effect of the multimedia file is improved.

As an optional embodiment, creating a target page corresponding to the source page in the target editor in step 204 includes:

creating a target page in a target editor according to the target page attribute;

Specifically, in importing the source page into the target editor, the target page corresponding to the source page can be adaptively created according to the original page attribute of the source page, so as to restore the multimedia file as much as possible. The third corresponding relation is a corresponding relation between the original page attribute and the target page attribute, and the original page attribute of the source page is mapped according to the preset third corresponding relation to obtain the corresponding target page attribute. And setting pages in the target editor according to the target page attributes, and creating a target page.

The original page attribute includes at least one of a page name, a page size and a page background, where the page name is used to identify a page, and the page name may include a level of the page and/or a serial number of the page, for example, in a PPT file, the page name may be a page theme under a synopsis view or may be a page number, which is not limited in this embodiment of the present application.
