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 method for processing electronic book-based typesetting according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
step S110: and acquiring picture elements obtained by analyzing original book pages of the electronic book.
Specifically, the original book page of the electronic book refers to a page before layout, and is usually a layout page. The original book page can be parsed by the page parser, so as to obtain each page element contained in the page, and in this step, the picture elements of the picture type need to be extracted from various page elements.
Step S120: when the number of the picture elements contained in the original book page is multiple, whether each picture element belongs to the fragment picture is judged according to the position relation among the multiple picture elements.
When the number of the picture elements contained in one original book page is multiple, the position relation among the picture elements is obtained, and whether the picture elements belong to the fragment pictures or not is judged according to the position relation. Wherein, the fragmented picture means: partial picture content contained in the full picture. Because the content of the insets in the electronic book is usually more, a large picture is often spliced by a plurality of small pictures, at this time, each small picture is a fragment picture, and the plurality of fragment pictures are commonly used for forming a large picture, so the position relationship among the fragment pictures is relatively fixed.
In the specific judgment, the judgment can be performed according to whether the position of each picture element is located in the middle of the page and occupies the main body area in the page. Typically, the content that alone forms a picture tends to be displayed centrally and occupies the main area of the page. Wherein, the main body area of the page is as follows: the page width is not smaller than the area of the first preset proportion of the total page width. In addition, whether other picture elements exist in the adjacent region of the picture element can be further determined, and if other picture elements do not exist in the adjacent region of one picture element, it is determined that the picture element does not belong to the fragmented picture. In summary, the positional relationship in the present embodiment includes: the position coordinates of the picture elements on the page, the occupied proportion of the picture elements on the page, the relative position relationship between the picture elements and other picture elements and the like. The present invention does not limit the specific meaning of the positional relationship.
Step S130: and if so, merging the picture elements belonging to the fragment pictures to obtain a target picture area containing the merged picture elements.
Since a plurality of picture elements belonging to the fragmented picture are commonly used to form a complete picture, the plurality of picture elements belonging to the fragmented picture need to be merged to obtain a target picture region including the merged picture elements. During the merging process, the number and the range of the picture elements to be merged may be further determined by combining the editing order of the picture elements, the spacing distance between the picture elements, and other factors. The target picture areas of the merged picture elements refer to: the picture element comprises a plurality of picture elements belonging to the fragment type picture, and the picture elements are arranged in the same picture.
Step S140: and executing screenshot processing aiming at the target picture area to obtain a screenshot picture corresponding to the target picture area, and generating page typesetting content corresponding to the original book page according to the screenshot picture.
Specifically, the screenshot picture is used as a complete picture element, so that typesetting processing is performed according to the complete picture element and other page elements contained in the original book page, and page typesetting content corresponding to the original book page is obtained. The screenshot picture completely reserves all page elements for forming the picture in a picture form, so that the problem that the composition mode is disordered is solved.
Therefore, the method can identify the integral picture formed by the plurality of picture elements, and reserve the composition mode of the picture, so that the finally obtained typesetting content is consistent with the original content of the electronic book, and further the typesetting efficiency and accuracy are improved.
Example two
Fig. 2 is a flowchart illustrating a method for processing electronic book-based typesetting according to another embodiment of the present invention. As shown in fig. 2, the method comprises the steps of:
step S200: acquiring page elements obtained by analyzing original book pages of the electronic book.
Specifically, the original book page of the electronic book refers to a page before layout, and is usually a layout page. The page resolver can resolve the original book pages, so that each page element contained in the original book pages is obtained. In the present embodiment, the original book page refers to a single page in the electronic book, considering that the pictures of the electronic book are not usually displayed across pages.
Step S210: and extracting picture elements from the analyzed page elements.
Specifically, picture elements of picture types need to be extracted from various types of page elements. The page element is a minimum unit forming page content, and specifically includes: text elements, picture elements, and path elements. Wherein, the text element refers to: elements composed of various texts such as English characters, Chinese characters and the like. The picture elements refer to: and elements composed of contents in various picture formats such as jpg. The path element refers to: an element formed by a path line, wherein the path line is used to connect any two end points by a straight line or a curved line. Since various types of page elements have corresponding attribute information, the picture elements can be extracted according to the attribute information of the page elements.
Step S220: when the number of the picture elements contained in the original book page is multiple, whether each picture element belongs to the fragment picture is judged according to the position relation among the multiple picture elements.
The main purpose of this step is to identify a plurality of fragmented pictures in the electronic book that are used to compose a complete picture. Since the number of fragmented pictures is necessarily multiple, if only one picture element is included in an original book page, the picture element usually does not belong to a fragmented picture. Accordingly, only when the number of the picture elements included in one original book page is multiple, it is necessary to determine whether the multiple picture elements belong to the fragmented picture.
Specifically, the determination may be made in at least one of the following two ways:
in the first mode, the element size of each picture element is obtained, and whether the picture element belongs to a fragment picture is judged according to the relative relationship between the element size and the page size of an original book page. The mode is mainly judged according to the size information. Wherein the element sizes of the picture elements include: length, width, etc. of the picture element. Accordingly, the page size of the original book page also includes the page length and the page width. The relative relationship between the element size of the picture element and the page size of the original book page mainly refers to: and the proportion of the picture elements in the original book page. Since a single picture is usually displayed in the middle of the page and occupies a certain page space, the picture element with smaller proportion can be determined as the fragment picture by detecting the proportion of the picture element in the page. In specific implementation, a ratio threshold may be set, for example, 20%, and if a ratio between the element size of the picture element and the page size of the original book page is smaller than the ratio threshold, it is determined that the picture element is a fragmented picture. In general, small pictures to be stitched into a large picture are generally small in size, and therefore, a fragmented picture can be quickly and efficiently recognized by size information.
In the second mode, the position information of each picture element in the original book page is obtained, and whether the picture elements adjacent to at least two positions belong to the fragment pictures is judged according to the position information. The position information is represented by position coordinates, and according to the position information of each picture element in the original book page, whether one picture element is in a centered state or a non-centered state can be judged, and whether other adjacent picture elements exist around one picture element can be judged. Accordingly, whether a picture element is a fragmented picture can be determined according to whether the picture element is in a centered state and the distance between two adjacent picture elements. Typically, picture elements that are in a non-centered state and/or have a separation distance from neighboring picture elements that is less than a preset separation threshold belong to a fragmented picture.
The two judgment methods can be used independently or in combination.
Step S230: and if so, merging the picture elements belonging to the fragment pictures to obtain a target picture area containing the merged picture elements.
Since the plurality of fragmented pictures are commonly used to form a complete electronic book illustration, the relative position relationship of each fragmented picture in the electronic book illustration is fixed, and in order to ensure that the relative position relationship is not disturbed in the typesetting process, a plurality of picture elements belonging to the fragmented pictures need to be merged to obtain a target picture region including the merged picture elements. Wherein, the target picture area means: and the multiple fragmented pictures jointly form an area corresponding to a complete electronic book illustration.
Therefore, in order to ensure that the layout of the e-book illustration is correct, it is necessary to ensure that all the page elements included in the target drawing region are page elements in the e-book illustration. Namely: the target picture area does not omit any page elements contained in the electronic book illustration, and the target picture area does not contain any page elements not belonging to the electronic book illustration.
In order to achieve the above object, in this step, the merging process may be performed according to the separation distance between the respective fragmented pictures. The method is realized by the following steps: merging at least two picture elements belonging to the fragmented picture, the position interval of which is smaller than a preset interval threshold value, to obtain a candidate picture area; judging whether the area range of the candidate picture area needs to be adjusted or not; if so, determining a target picture area according to the area range of the adjusted candidate picture area; if not, the target picture area is directly determined according to the area range of the candidate picture area. Therefore, the method mainly performs pairwise merging processing according to the position interval between two fragmented pictures so as to merge the fragmented pictures with closer intervals.
In specific implementation, it is considered that some interfering page elements may exist in the candidate picture region obtained by combining according to the position interval, for example, page elements which do not belong to the e-book illustration may be included; alternatively, page elements belonging to the e-book illustration may also be missed. Therefore, whether the area range of the candidate image area needs to be adjusted or not needs to be judged, and in specific implementation, the adjustment can be performed through the editing sequence of each image element in the original book page: after merging at least two picture elements belonging to the fragmented pictures and having a position interval smaller than a preset interval threshold value to obtain a candidate picture area, acquiring an editing order of each picture element contained in the candidate picture area in an original book page; judging whether the area range of the candidate picture area needs to be adjusted or not according to the editing sequence; and if so, determining the target picture area according to the area range of the adjusted candidate picture area. When judging whether the area range of the candidate picture area needs to be adjusted according to the editing sequence, sequencing the editing sequence of each picture element contained in the candidate picture area, and judging whether the sequence interval between two picture elements adjacent to the sequence is larger than a preset sequence threshold value; if so, at least one picture element in the two picture elements adjacent to the sequence is removed from the candidate picture area, and the area range of the candidate picture area is adjusted according to the remaining picture elements. The editing order refers to an obtaining order of each page element in an original book page, and generally, the editing order of each element in the same picture should be continuous or not greatly different, so that picture elements with greatly different editing orders may not belong to the picture. For example, if the editing order of the fragmented pictures in the candidate picture area corresponding to one picture is mostly distributed in the first interval, the first interval is between 1 and 100. At this time, if the editing order of a certain fragmented picture is located in the second interval, which is located between 1000-1100, it is determined that the fragmented picture located in the second interval does not belong to the picture content, and the fragmented picture should be removed.
In addition, in this embodiment, when determining whether the area range of the candidate picture area needs to be adjusted, the determination may be performed according to whether the candidate picture area contains a text. Specifically, whether a text is contained in the candidate picture area is judged; if so, adjusting the area range of the candidate picture area according to the position of the text. The candidate picture area should not contain the text, and therefore, the page elements that conflict with the position of the text should be removed from the candidate picture area.
In addition, the inventor finds that some pictures further contain text contents, and the text contents belong to a part of the pictures, different from text texts. For example, in the layout text, the text and the picture show the stacking effect, but in the streaming typesetting mode, the text and the picture are typeset separately, so that the stacking effect cannot be shown. At this time, in order to ensure that the characters belonging to the picture content can be divided into the candidate picture areas and maintain the stacking effect of the characters and the pictures, the following processing is performed:
when at least two picture elements belonging to the fragment pictures with the position interval smaller than a preset interval threshold are combined to obtain a candidate picture area, further obtaining text elements obtained by analyzing original book pages of the electronic book; acquiring first position information of at least two picture elements belonging to the fragmented pictures in an original book page and second position information of text elements in the original book page; judging whether a text element coincident with at least two picture elements belonging to the fragment pictures exists or not according to the first position information and the second position information; if so, merging the at least two picture elements belonging to the fragmented picture and the text element coincident with the at least two picture elements belonging to the fragmented picture together to obtain a candidate picture area. According to the attribute information of the page elements, the fact that one page element belongs to a picture element or a text element can be determined, and for each page element, position coordinate data of the page element can be acquired. Correspondingly, when merging processing is executed, acquiring first position information of at least two picture elements belonging to the fragmented pictures in an original book page aiming at the at least two picture elements belonging to the fragmented pictures with the position intervals smaller than a preset interval threshold value, so as to determine the position ranges of the at least two picture elements belonging to the fragmented pictures in the original book page; and acquiring second position information of each text element in the original book page, judging whether text elements which are overlapped with at least two picture elements belonging to the fragment pictures exist according to whether the first position information and the second position information are overlapped, and merging the text elements which are overlapped with the picture elements into the candidate picture area together when the judgment result is yes. Wherein the coincidence comprises: all or part of the text, i.e. the text may all coincide with the picture elements, or the text may also partly coincide with the picture elements.
When at least two picture elements belonging to the fragmented picture and a text element coincident with the at least two picture elements belonging to the fragmented picture are combined together, the method is realized in the following mode: firstly, determining a first rectangular area corresponding to at least two picture elements belonging to the fragmented picture and a second rectangular area corresponding to a text element coinciding with the at least two picture elements belonging to the fragmented picture; then, determining a circumscribed rectangle corresponding to the first rectangular region and the second rectangular region, and performing merging processing on picture elements and text elements contained in the circumscribed rectangle. Wherein, the first rectangular area corresponding to at least two picture elements belonging to the fragmented picture refers to: at least two first external rectangles corresponding to picture elements belonging to the fragment type picture; correspondingly, the second rectangular region corresponding to a text element coinciding with at least two picture elements belonging to the fragmented picture refers to: a second circumscribed rectangle to which the text element corresponds. Therefore, the circumscribed rectangle corresponding to the first rectangular region and the second rectangular region means: a common circumscribed rectangle corresponding to the first and second circumscribed rectangles.
Step S240: and executing screenshot processing aiming at the target picture area to obtain a screenshot picture corresponding to the target picture area, and generating page typesetting content corresponding to the original book page according to the screenshot picture.
Specifically, the screenshot picture is used as a complete picture element, so that typesetting processing is performed according to the complete picture element and other page elements contained in the original book page, and page typesetting content corresponding to the original book page is obtained. The screenshot picture completely reserves page elements such as all fragment pictures for forming the picture in a picture form, so that the problem that the composition mode is disturbed is solved.
In this embodiment, an original book page of the electronic book is a layout page; the page typesetting content is streaming typesetting content.
Therefore, the method can identify the integral picture formed by the plurality of picture elements, and reserve the composition mode of the picture, so that the finally obtained typesetting content is consistent with the original content of the electronic book, and further the typesetting efficiency and accuracy are improved. In addition, the method can accurately identify the picture area according to various factors such as the spacing distance, the editing sequence and the like, and can also accurately process the picture containing the characters, so that the content after screenshot is ensured to be consistent with the picture area, and the typesetting accuracy is improved.
