Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Example one

Fig. 1 is a flowchart illustrating a document conversion method based on paragraph zooming-in amount according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:

step S101, identifying the layout document to obtain an initial style parameter and a paragraph retraction amount of each paragraph in the layout document, and dividing the paragraphs with the same initial style parameter into the same paragraph group.

In order to enable paragraphs with different paragraph shrinkage amounts in the layout document to have different display styles in the converted streaming document, the styles, paragraph shrinkage amounts and the like of the paragraphs in the layout document can be identified, so that initial style parameters and paragraph shrinkage amounts of the paragraphs in the layout document are obtained. Wherein, the initial style parameter is a parameter for reflecting the style of the paragraph in the layout document; the paragraph retraction amount is a retraction amount of a paragraph top line, or a distance from a left or right boundary of a minimum circumscribed rectangle of a paragraph to a left or right boundary of a page, for example, there are consecutive three paragraphs of characters on a certain page, the left boundary of a first paragraph of characters is 10 characters from the left boundary of the page, the left boundary of a second paragraph of characters is 15 characters from the left boundary of the page, and the left boundary of a third paragraph of characters is 20 characters from the left boundary of the page, so that it can be known that the paragraph retraction amounts of the first to third paragraphs of characters are 10 characters, 15 characters, and 20 characters, respectively. The reduction amount of the paragraph top line may be specifically a distance from the left or right boundary of the minimum bounding rectangle of the paragraph top line text to the left or right boundary of the page.

After the initial style parameters of each paragraph and the paragraph retraction amount of each paragraph are obtained, each paragraph can be grouped according to the initial style parameters, and specifically, paragraphs with the same initial style parameters can be divided into the same paragraph group, so that each paragraph in the same paragraph group has the same initial style parameters, and paragraphs in different paragraph groups have different initial style parameters, thereby conveniently realizing the initial grouping of paragraphs based on the initial style parameters.

And step S102, grouping the paragraphs in each paragraph group according to the paragraph retraction amount to obtain a paragraph group corresponding to the paragraph group.

After the preliminary grouping of paragraphs based on the initial style parameters is completed, the paragraphs in each paragraph group are further grouped secondarily based on paragraph advance. In step S102, for each paragraph group, the paragraphs in the paragraph group are grouped according to the paragraph advance amount, so as to obtain the paragraph group corresponding to the paragraph group. For example, paragraphs in the paragraph group with the same or similar paragraph shrinkage amounts may be divided into the same paragraph group, so that paragraphs in the same paragraph group have not only the same initial style parameters but also the same or similar paragraph shrinkage amounts, thereby realizing effective grouping of paragraphs.

Step S103, configuring corresponding target style parameters for each paragraph group, and setting the display style of the paragraphs in each paragraph group in the streaming document according to the target style parameters corresponding to each paragraph group.

After the further grouping of all paragraph groups is completed, a plurality of paragraph groups are obtained. For each paragraph group, a corresponding target style parameter may be configured according to an initial style parameter, a paragraph shrinkage amount, and the like of the paragraphs in the paragraph group. For example, the target style parameters configured for different paragraph groups are different. The target style parameter is a parameter for reflecting the style of a paragraph in a streaming document.

After the configuration of the target style parameters is completed, the display styles of the paragraphs in the paragraph groups in the streaming document can be set in batches according to the target style parameters corresponding to the paragraph groups, so that the setting of the display styles of the paragraphs in the streaming document can be quickly completed, and the paragraphs with different paragraph retraction volumes in the format document can be effectively distinguished through different display styles by configuring different target style parameters for different paragraph groups.

By using the document conversion method based on paragraph shrinkage provided by the embodiment, paragraphs are grouped based on the initial style parameters of the paragraphs in the layout document and the paragraph shrinkage, so that the paragraphs in the same paragraph group have the same initial style parameters and the same or similar paragraph shrinkage, thereby realizing effective grouping of the paragraphs; according to the target style parameters configured for each paragraph group, the display styles of the paragraphs in each paragraph group in the streaming document can be set in batches, so that the setting of the display styles of the paragraphs in the streaming document can be quickly completed, the document conversion efficiency is effectively improved, and the paragraphs with different paragraph retraction amounts in the format document can be effectively distinguished in the streaming document through different display styles by configuring different target style parameters for different paragraph groups.

Example two

Fig. 2 is a flowchart illustrating a document conversion method based on paragraph zooming-in amount according to a second embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:

step S201, identifying the layout document to obtain an initial style parameter and a paragraph shrinkage amount of each paragraph in the layout document, and dividing the paragraphs having the same initial style parameter into the same paragraph group.

When the layout document needs to be converted into a corresponding streaming document, the style, the paragraph shrinkage amount and the like of each paragraph in the layout document can be identified, so that the initial style parameter and the paragraph shrinkage amount of each paragraph in the layout document are obtained. In particular, the initial style parameters may specifically comprise one or more of the following parameters: font, font size, character color, character background, bolding, underlining, italics. The initial style parameter may also include other parameters, and those skilled in the art may set the initial style parameter according to actual needs, which are not specifically limited herein.

After the initial style parameter and the paragraph advance amount of each paragraph are obtained, the paragraphs may be initially grouped based on the initial style parameter. Specifically, paragraphs having the same initial style parameter are divided into the same paragraph group.

Step S202, extracting odd pages and even pages from the layout document, and identifying the layout center of the odd pages and the layout center of the even pages.

For some layout documents, the centers of odd pages and even pages may not be aligned, for example, to facilitate binding of paper documents, in a layout document, the centers of odd pages are set to be offset toward the right boundary of the document page compared to the centers of even pages. In this case, if paragraphs having the same or similar paragraph shrinkage amount in a paragraph group are directly divided into the same paragraph group, it is likely that a grouping error occurs. In order to effectively avoid the grouping error, in this embodiment, the odd page and the even page may be extracted from the layout document, and then the odd page and the even page are respectively identified to obtain the layout center of the odd page and the layout center of the even page. The layout center of the page can be embodied by the distance between the main content of the document in the page and the left boundary, the right boundary, the upper boundary and the lower boundary of the page.

Step S203, calculating the offset of the plate center between the odd page and the even page according to the plate center of the odd page and the plate center of the even page.

In an optional implementation manner, according to the center of the odd page and the center of the even page, a first distance between the main content of the document in the odd page and the left boundary of the page and a second distance between the main content of the document in the even page and the left boundary of the page are determined, the first distance and the second distance are subtracted, and the calculation result is the center offset between the odd page and the even page. For example, the first distance is 20 characters and the second distance is 15 characters, then the offset of the plate center is calculated to be 5 characters.

In another optional implementation manner, any odd page and any even page can be overlapped together in a page turning, translation and other manners, and after the overlapping is performed, the difference between the block center of the odd page and the block center of the even page is calculated to obtain the block center offset between the odd page and the even page.

The execution sequence of step S201, step S202, and step S203 is not limited. The sequence of the steps shown in this embodiment is only a specific example, and in this embodiment, step S201 is executed first, and then step S202 and step S203 are executed. Those skilled in the art may also perform step S201 after performing step S202 and step S203, or step S201 and step S202 may also be performed simultaneously.

After the paragraph groups are obtained by dividing and the plate center offset is calculated, the paragraphs in the paragraph groups can be grouped according to the paragraph indentation amount and the plate center offset for each paragraph group, so as to obtain the paragraph group corresponding to the paragraph group. Specifically, the process can be implemented through step S204 to step S206.

Step S204, judging whether the offset of the plate center is smaller than a first preset threshold value; if yes, go to step S205; if not, go to step S206.

In this embodiment, a first preset threshold is set, and whether the block center of the odd page and the block center of the even page are aligned is determined by judging whether the block center offset is smaller than the first preset threshold. The first preset threshold may be set by a person skilled in the art according to actual needs, for example, the first preset threshold may be set to 0.5 characters. Specifically, if the offset of the center of the plate is smaller than the first preset threshold, it may be determined that the center of the odd page and the center of the even page are aligned, and then step S205 is executed; if the offset of the plate center is greater than or equal to the first preset threshold, it may be determined that the plate center of the odd page and the plate center of the even page are not aligned, and step S206 is performed.

In step S205, for each paragraph group, each paragraph in the paragraph group is divided into a corresponding paragraph group.

When the offset of the center of the plate is smaller than the first preset threshold value, which is determined in step S204, it is described that the center of the odd page and the center of the even page are aligned, and the paragraphs in each paragraph group can be directly grouped secondarily based on the paragraph shrinkage amount without correcting the paragraph shrinkage amount of each paragraph obtained in step S201.

Specifically, for each paragraph group, paragraphs in the paragraph group that have the same or similar paragraph shrinkage amount are divided into the same paragraph group. In this embodiment, a second predetermined threshold can be used to find paragraphs with the same or similar paragraph shrinkage amount. The difference of paragraph retraction amounts of any two paragraphs in the same paragraph group containing a plurality of paragraphs is smaller than a second preset threshold value through division.

Suppose that a paragraph group includes 6 paragraphs, which are paragraphs 1 to 6, respectively, where the paragraph advance amount of paragraph 1 is 22.1 characters, the paragraph advance amount of paragraph 2 is 22.0 characters, the paragraph advance amount of paragraph 3 is 21.9 characters, the paragraph advance amount of paragraph 4 is 25.1 characters, the paragraph advance amount of paragraph 5 is 25.0 characters, and the paragraph advance amount of paragraph 6 is 24.9 characters. If the second preset threshold is 0.3 characters, the paragraph group is further divided into two paragraph groups by calculating the difference between the paragraph reductions of two paragraphs in the paragraph group, wherein the difference between the paragraph reductions of any two paragraphs in paragraph 1, paragraph 2 and paragraph 3 is smaller than the second preset threshold, and the difference between the paragraph reductions of any two paragraphs in paragraph 4, paragraph 5 and paragraph 6 is smaller than the second preset threshold.

Step S206, for each paragraph group, according to the offset of the plate center and the page number corresponding to the paragraph in the paragraph group, correcting the paragraph shrinkage amount of the paragraph in the paragraph group, and then dividing each paragraph in the paragraph group into the corresponding paragraph group.

When the offset of the center of the plate is determined to be greater than or equal to the first preset threshold in step S204, it is described that the center of the odd page and the center of the even page are not aligned, and the paragraph shrink amount of each paragraph obtained in step S201 needs to be corrected according to the offset of the center of the plate before the paragraphs in each paragraph group are grouped secondarily based on the paragraph shrink amount. By the processing mode, the method can be suitable for processing the layout document with the odd-even page layout centers not aligned, and the situation of grouping errors is effectively avoided.

Specifically, paragraphs with page numbers belonging to the target numerical value type can be screened out from the paragraph group, and then, for each paragraph with a page number belonging to the target numerical value type, the paragraph shrinkage amount of the paragraph is added or subtracted with the offset of the plate center, so that the paragraph shrinkage amount is corrected. Wherein the target value type may be even or odd. After the correction, each paragraph in the paragraph group is divided into the corresponding paragraph group. The difference value of paragraph retraction amounts of any two paragraphs in the same paragraph group containing a plurality of paragraphs is smaller than a second preset threshold value.

If it is determined in step S203 that the first distance is greater than the second distance and the offset of the center of the plate between the odd page and the even page is 5 characters, the corresponding correction manner may include two manners, where manner 1 is to screen out paragraphs with even page numbers from the paragraph group, and then add the paragraph shrinkage amount and the offset of the center of the plate of each paragraph with even page numbers; the mode 2 is to screen out paragraphs with odd page numbers from the paragraph group, and then perform subtraction processing on the paragraph retraction amount and the plate center offset amount of each paragraph with odd page numbers. The paragraph advance amount may be corrected by selecting one of the two modes.

Suppose a paragraph group includes 8 paragraphs, which are paragraphs 1 to 8, where the page numbers corresponding to paragraphs 1 to 4 are odd numbers, the page numbers corresponding to paragraphs 5 to 8 are even numbers, the paragraph shrinkage amount of paragraph 1 is 22.1 characters, the paragraph shrinkage amount of paragraph 2 is 22.0 characters, the paragraph shrinkage amount of paragraph 3 is 25.0 characters, the paragraph shrinkage amount of paragraph 4 is 24.9 characters, the paragraph shrinkage amount of paragraph 5 is 17.1 characters, the paragraph shrinkage amount of paragraph 6 is 17.0 characters, the paragraph shrinkage amount of paragraph 7 is 20.0 characters, and the paragraph shrinkage amount of paragraph 8 is 19.9 characters. Taking the target value type as an even number and the correction mode as an example of adding the paragraph shrinkage amount and the center offset of the paragraph, it is described that for the paragraph whose page number belongs to the even number, the center offset needs to be added on the basis of the original paragraph shrinkage amount, and the added result is the corrected paragraph shrinkage amount. Through the correction processing, the paragraph advance amount corrected by the paragraph 5 is 22.1 characters, the paragraph advance amount corrected by the paragraph 6 is 22.0 characters, the paragraph advance amount corrected by the paragraph 7 is 25.0 characters, and the paragraph advance amount corrected by the paragraph 8 is 24.9 characters. If the second preset threshold is 0.3 characters, then calculating the difference between the paragraph shrink amounts of two paragraphs in the paragraph group, and if the difference between the paragraph shrink amounts of any two paragraphs in paragraph 1, paragraph 2, paragraph 5 and paragraph 6 is smaller than the second preset threshold, and if the difference between the paragraph shrink amounts of any two paragraphs in paragraph 3, paragraph 4, paragraph 7 and paragraph 8 is also smaller than the second preset threshold, then dividing paragraph 1, paragraph 2, paragraph 5 and paragraph 6 into one paragraph group, and dividing paragraph 3, paragraph 4, paragraph 7 and paragraph 8 into another paragraph group, thereby further dividing the paragraph group into two paragraph groups.

Step S207, configuring corresponding target style parameters for each paragraph group, and setting a presentation style of the paragraphs in each paragraph group in the streaming document according to the target style parameters corresponding to each paragraph group.

Different target style parameters can be configured for different paragraph groups according to the initial style parameters, paragraph shrinkage amounts and the like of paragraphs in different paragraph groups. The target style parameters may specifically comprise one or more of the following parameters: font, font size, character color, character background, paragraph shrinkage amount, bolding, underlining, italics. The target style parameter may also include other parameters, and those skilled in the art may set the target style parameter according to actual needs, which are not specifically limited herein.

In an optional implementation manner, the target style parameters configured for the paragraph group may be completely the same as the initial style parameters and the paragraph indentation amount of the paragraphs in the paragraph group, and this configuration enables the converted streaming document to maximally restore the layout structure of the layout document, and maintains the aesthetic property of the document content.

For example, if the paragraph shrinkage amount of a paragraph in a paragraph group is 22 characters, the initial style parameter of the paragraph includes a font of song and a font size of four, and the target style parameter configured for the paragraph group may include a font of song, a font size of four and a paragraph shrinkage amount of 22 characters, so as to maximally restore the layout structure of the layout document.

In another optional implementation manner, the target style parameters configured for the paragraph group may be partially or completely different from the initial style parameters and the paragraph indentation amount of the paragraphs in the paragraph group, and this configuration enables the converted streaming document to adopt a different layout structure from the layout document to reflect the hierarchical sense between the paragraphs with different paragraph indentation amounts in the layout document, which is helpful for improving the presentation effect of the document content.

For example, if the paragraph shrinkage amount of a paragraph in a paragraph group is 22 characters, the initial style parameter of the paragraph includes a font of song and a font size of four, the target style parameter configured for the paragraph group may include a font of song, a font size of four, and a color of the character of blue; the paragraph shrinkage amount of the paragraphs in the other paragraph group is 15 characters, the initial style parameters of the paragraphs include a font of song and a font size of four, and the target style parameters configured for the paragraph group may include a font of song, a font size of four and a character color of yellow. By adding different character colors to paragraphs with the same initial style parameters and different paragraph retraction amounts, the paragraphs can be distinguished, and the display effect and the attractiveness of the document content can be improved.

Considering that in the prior art, a streaming document is generally constructed in an HTML5 manner, and a tag language is adopted, and document content can be presented in a scrolling manner of a waterfall streaming type, it is possible to add a corresponding presentation style to a tag corresponding to each paragraph in a source file corresponding to the streaming document to enable each paragraph to be presented in accordance with the corresponding presentation style when the streaming document is presented.

In step S207, in the source file corresponding to the streaming document, a presentation style corresponding to the tag may be set for the tag corresponding to each paragraph in each paragraph group according to the target style parameter corresponding to each paragraph group. In practical application, in a source file corresponding to a streaming document, paragraphs are usually defined by < p > tags, and then in the source file corresponding to the streaming document, corresponding presentation styles can be set for the < p > tags corresponding to each paragraph in each paragraph group according to target style parameters corresponding to each paragraph group, so that the setting of the presentation styles of each paragraph in the streaming document is conveniently realized.

By using the document conversion method based on paragraph shrink amount provided by the embodiment, whether the even and odd page layout centers in the layout document are aligned can be accurately identified, for the case that the even and odd page layout centers are not aligned, the paragraph shrink amount of paragraphs in paragraph groups obtained by dividing based on the initial style parameters is corrected through the offset of the layout centers, and paragraphs in each paragraph group are grouped secondarily based on the corrected paragraph shrink amount, so that the accurate grouping of paragraphs is realized, and the occurrence of grouping errors is effectively avoided; and moreover, according to the target style parameters configured for each paragraph group, the display styles of the paragraphs in each paragraph group in the streaming document can be set in batch and quickly, the document conversion workload is reduced, the document conversion efficiency is effectively improved, and by configuring different target style parameters for different paragraph groups, the paragraphs in the format document with different paragraph retraction amounts can conveniently reflect the layering sense among the paragraphs and effectively distinguish the paragraphs in the streaming document through different display styles, so that the attractiveness and the display effect of the document content are effectively improved.
