Detailed Description
Example one
Fig. 1 is a flowchart illustrating a window partial refresh method according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
step S101, receiving an editing operation of a first editing content object of a first electronic book triggered by a user in an editing window.
When a user (a proofreader of a first electronic book, hereinafter referred to as a user) edits the first electronic book, a user interface used by the user includes an editing window on which the first electronic book is displayed and a preview window on which a second electronic book is displayed. The first electronic book and the second electronic book have the same content but different formats. The first electronic book is a format-type typeset electronic book, such as a pdf electronic book, and the second electronic book is a stream-type typeset electronic book, such as an epub electronic book. The first electronic book and the second electronic book display the same content using different layout formats.
As shown in fig. 2, the editing window on the left side displays a first electronic book, and the preview window on the right side displays a second electronic book. The preview window may be displayed in a html language, for example, to generate a second e-book. Specifically, before a user edits a first electronic book, each content object included in the first electronic book is analyzed, and a node tag of a second content object of a second electronic book is generated according to the first content object of the first electronic book. Meanwhile, the corresponding relation between the first content object of the first electronic book and the second content object of the second electronic book is recorded. The first content object and the second content object comprise content objects such as titles, paragraphs, pictures, text annotations, picture legends (picture titles, picture annotations, etc.). For the second electronic book, different second content objects respectively correspond to different node tags. If the title uses an h node label, the paragraph uses a p node label, the picture uses an img node label, etc., this is not limited herein.
In addition to generating a node tag of a second content object of a second electronic book according to a first content object of a first electronic book, in order to facilitate reading of a reader, a first content object in the first electronic book needs to be processed. As shown in fig. 3a, in the editing window, the first content object of 122 in the displayed first electronic book is a paragraph, the first content object of 123-125 is an annotation, the first content object of 128 is a picture, the first content object of 129 is a legend, and the first content object of 130 is a paragraph, when the first electronic book is actually read, the paragraph corresponding to 122 and the paragraph corresponding to 130 should be front and back parts of the same paragraph, but are divided by other content objects in the first electronic book, which affects the consistency of reading by the reader; or when the front part and the rear part of one paragraph in the first electronic book are positioned on two adjacent pages due to page layout, displaying different paragraphs in the first electronic book; or, when the first electronic book is displayed in a column-dividing manner, the front part and the rear part of a paragraph are respectively located in different columns, and the paragraph is displayed as different paragraphs in the first electronic book. The second electronic book is directly generated according to the display mode of the first electronic book, so that the front part and the rear part of a paragraph are respectively displayed as different paragraphs, and the completeness of the paragraph is influenced. Therefore, it is further necessary to identify each paragraph in the first electronic book, and determine whether two adjacent paragraphs in the first electronic book are a first paragraph and a last paragraph, respectively. The first segment begins with a normal segment and ends with an abnormal segment, and the last segment begins with an abnormal segment and ends with a normal segment. The normal paragraph beginning includes paragraph beginning indents, e.g., the normal paragraph begins with two text indents, the normal paragraph end includes an end punctuation and paragraph end indents, the end punctuation includes, e.g., a period, a question mark, an exclamation mark, a quotation mark, etc., the normal paragraph end ends with an end punctuation, and the paragraph end generates an end indent that is different from the length of the normal line of text in the paragraph, etc. According to the characteristics of the first paragraph and the last paragraph, judging whether the paragraphs in the first electronic book are the first paragraph according to the sequence of the paragraphs in the first electronic book, if the paragraphs are judged not to be the first paragraph, judging whether the next paragraph is the first paragraph according to the sequence of the paragraphs until all the paragraphs in the first electronic book are not the first paragraph or judging that a certain paragraph in the first electronic book is the first paragraph. If all paragraphs in the first electronic book are not head sections, determining that the head sections and the tail sections do not exist in the first electronic book; if a certain paragraph in the first electronic book is judged to be a first paragraph, whether a next paragraph of the paragraph is a last paragraph needs to be judged; if so, determining that the two adjacent paragraphs in the first electronic book are respectively a first paragraph and a last paragraph. Furthermore, the editing window and the preview window can adopt, for example, corresponding electronic books are displayed by taking chapters as units, so that the processing is conveniently carried out by taking chapters as units, and the range of editing operation is narrowed, so that the influence of the editing operation is within one chapter, and the content of other chapters is not influenced. When judging whether the paragraph of the first electronic book is the first paragraph or the last paragraph, the paragraph in the current chapter of the first electronic book currently displayed in the editing window can be judged, the judgment range is narrowed, and the processing efficiency is improved.
For the convenience of reading by the reader, the contents of the corresponding first segment and the corresponding last segment are merged in the second electronic book displayed in the preview window, and the contents of the last segment are merged to the end of the contents of the first segment and displayed as a complete paragraph, for example, the paragraph outlined and selected by the square frame in fig. 3b is the merging of the paragraph corresponding to 122 and the paragraph corresponding to 130 in fig. 3 a. The merged paragraphs in the second ebook are arranged according to the position of the first paragraph in the first ebook, and for other content objects between the first paragraph and the last paragraph, such as the first content object of 123-125, the first content object of 128, and the first content object of 129 in the first ebook, are arranged after the merged paragraphs according to the position in the first ebook, as shown in fig. 3 b.
After the second electronic book is obtained, the first electronic book is displayed on the editing window, the second electronic book is displayed on the preview window, and a user can perform editing operation on the first content object in the first electronic book in the editing window, wherein the editing operation can influence the display of the second electronic book in the preview window. In the embodiment, the time for the preview window to display the whole second electronic book after refreshing is reduced, and partial content objects of the second electronic book affected by the editing operation are partially refreshed, so that the time consumed by refreshing is reduced. Specifically, an editing operation of a first editing content object of a first electronic book triggered by a user in an editing window is received. The first editing content object is a first content object selected by a user in an editing window, and editing operation is performed on the first editing content object.
Step S102, determine whether the position of the first edited content object is located between the beginning and end segments of the first electronic book, and whether the editing operation is associated with segment modification.
For the first edited content object, it is first determined whether its position in the first electronic book is located between the beginning and ending segments of the first electronic book, where the beginning and ending segments include the beginning and ending segments, as shown in fig. 3a, the position of the first content object of 123 and 125, the first content object of 128, and the first content object of 129 in the first electronic book are located between the beginning and ending segments. Specifically, two paragraphs of which the content object adjacent to the first edited content object in the first electronic book is a paragraph may be obtained, and whether the two paragraphs are a first paragraph and a last paragraph is determined. The specific judgment mode refers to the description of step S101; alternatively, when it is determined in step S101 that two paragraphs are respectively a first paragraph and a last paragraph, the corresponding marked paragraphs are the first paragraph and the last paragraph, and whether two paragraphs adjacent to the first edited content object are respectively the first paragraph and the last paragraph is determined according to the mark, which is not limited herein. If two paragraphs adjacent to the first edited content object are respectively judged to be a head paragraph and a tail paragraph, whether the first edited content object is a text annotation or a chart and question and drawing or not needs to be continuously judged, and whether the editing operation is to set the content object as a text or not needs to be continuously judged. Since the text annotation or the chart and chart annotation is not a text body, the display mode is different from that of a paragraph, and the node label in the second electronic book is different from that of the paragraph. Setting a text note or a chart and caption note as a text results in an increase of paragraphs, i.e., paragraph modifications can be associated with editing operations. When the position of the first edited content object in the first electronic book is located between the head and tail sections of the first electronic book, the first edited content object is set as a text, so that the sections are added, the head section and the tail section in the second electronic book cannot be directly merged, and the influence on the display of the head section and the tail section due to the addition of the sections needs to be considered.
When it is determined that the position of the first edited content object is located between the beginning and end sections of the first electronic book and the editing operation is associated with a paragraph modification, step S103 is executed.
Step S103, acquiring node labels of head and tail sections of a second electronic book corresponding to the head and tail sections of the first electronic book and node labels of a second content object corresponding to the first edited content object in the preview window.
According to the corresponding relation between the first content object of the first electronic book and the second content object of the second electronic book, the node labels of the head and tail sections of the second electronic book corresponding to the head and tail sections of the first electronic book and the node labels of the second content object corresponding to the first editing content object in the preview window can be correspondingly obtained.
And step S104, modifying the node labels of the head and tail sections of the second electronic book and the node labels of the second content object according to the editing operation, and finishing the local refreshing of the preview window according to the modified node labels.
According to the editing operation, the node label of the second content object corresponding to the first editing content object is modified, and the node label is changed into the node label corresponding to the paragraph, so that the new paragraph is added. Meanwhile, the contents of the merged first segment and the merged last segment in the second electronic book need to be split, and for the first segment, the contents in the node tag corresponding to the first segment are modified, wherein the contents of the merged last segment are not included any more; for the tail section, a node label corresponding to the tail section needs to be added, and the content of the tail section is recorded. After the node tag of the second electronic book is modified, the position of the modified node tag in the second electronic book is also required to be set according to the positions of the first segment, the first edited content object and the tail segment in the first electronic book, and the local refreshing of the preview window is completed according to the modified node tag. Specifically, as shown in fig. 4, the first content object of 123 of the first electronic book in the editing window on the left side is located between the beginning and end segments of the first electronic book, and the first content object (annotation) of 123 is set as a text, so that the associated segment is modified, the corresponding preview window on the right side modifies the second electronic book, and the second electronic book re-splits the content of the original merged beginning segment and end segment. The paragraph selected in the block in fig. 3b is the combination of the paragraph corresponding to 122 and the paragraph corresponding to 130, and in fig. 5, the paragraph corresponding to 122 and the paragraph corresponding to 130 are not combined any more, a node tag is generated for the paragraph corresponding to 130, and the content of the paragraph corresponding to 130 is recorded. And then, according to the positions of the node tags in the second electronic book, which are set correspondingly to the positions of the first content objects 122, 123 and 130 in the first electronic book, local refreshing of the second electronic book in the preview window is completed according to the modified node tags, and refreshing can be performed based on the node tags in the second electronic book during refreshing. If the second electronic book is generated by adopting html language, the node labels of the second electronic book can be directly modified, added, deleted and the like by utilizing the html tree structure after being determined, and the node labels after being processed are refreshed according to the tree structure, so that the situation that all the node labels are rendered and refreshed is avoided, and the refreshing time is greatly saved. The above is for illustration, and the specific implementation may be set according to implementation, and is not limited herein.
Further, the first content objects included between the head and tail sections of the first electronic book further include first non-edited content objects other than the first edited content object. As shown in fig. 4, the first and last sections of the first electronic book in the editing window on the left side are the first section corresponding to 122 and the last section corresponding to 130, and first content objects 124, 125, 128 and 129 are included between the first and last sections in addition to the first edited content object of 123, and these first content objects are first non-edited content objects. According to the corresponding relation between the first content object of the first electronic book and the second content object of the second electronic book, besides acquiring the node tag of the head and tail section of the second electronic book corresponding to the head and tail section of the first electronic book and the node tag of the second content object corresponding to the first edited content object of the first electronic book in the preview window, acquiring the node tag of the second content object corresponding to the first unedited content object included between the head and tail sections of the first electronic book in the preview window. And according to the editing operation, modifying the node label of the second content object corresponding to the first editing content object, splitting the head section and the tail section which are combined in the second electronic book, modifying the node label corresponding to the head section, and increasing the node label corresponding to the tail section. And correspondingly setting the positions of the modified node labels in the second electronic book according to the positions of the head section, the first edited content object, the first non-edited content object and the tail section in the first electronic book, and finishing the local refreshing of the preview window according to the modified node labels. Second Ebook of Preview Window As shown in FIG. 5, the position of the node tag in the second Ebook is set to refresh according to the position of the first content object of 122, 123, 124, 125, 128, 129, 130 in the first Ebook.
According to the window local refreshing method provided by the invention, the editing operation of the editing window in the user interface is judged, when the position of the first editing content object is judged to be positioned between the head and tail sections of the first electronic book and the editing operation is associated with section modification, the node labels of the head and tail sections of the second electronic book corresponding to the head and tail sections of the first electronic book and the node labels of the second content object corresponding to the first editing content object in the preview window are correspondingly obtained, the node labels of the head and tail sections of the second electronic book and the node labels of the second content object are modified according to the editing operation, and the modified node labels are locally refreshed to complete the local refreshing of the preview window, so that the time spent on rendering each section, section and the like of the whole second electronic book is reduced, and the rendering efficiency is improved.
Example two
Fig. 6 is a flowchart illustrating a window partial refresh method according to another embodiment of the present invention, and as shown in fig. 6, the method includes the following steps:
step S601, receiving an editing operation of a first editing content object of a first electronic book triggered by a user in an editing window.
Editing operations include, for example, content object deletion, content object style modification, content object set to body, and the like. Specifically, the content object deletion is to delete a first edited content object in a first electronic book; the content object style is modified into a first editing content object in the first electronic book, such as font modification, font size modification, picture style modification and the like; setting the content object to the body changes the type of the first edited content object in the first e-book, modifying it to a new paragraph.
Step S602, determine whether the position of the first edited content object is located between the beginning and end segments of the first electronic book, and whether the editing operation is associated with a segment modification.
Judging the position of the first edited content object in the first electronic book, judging whether the first edited content object is positioned between the head and tail sections of the first electronic book, if not, the editing operation of the first edited content object does not affect the change of the head and tail sections, other first content objects do not need to be changed, only the node label of the second content object corresponding to the first edited content object can be processed, and executing the step S603.
And if the position of the first editing content object is judged to be positioned between the head and tail sections of the first electronic book, further judging whether the editing operation is associated with section modification. If the editing operation is deletion of a content object or modification of a style of the content object, the editing operation modifies only the first edited content object during modification without affecting other first content objects or adding paragraphs, and then it is determined that the editing operation is not associated with paragraph modification, and step S603 is executed.
Step S603, obtaining a node tag of a second content object corresponding to the first edited content object in the preview window, deleting and/or modifying the node tag, and completing local refreshing of the preview window according to the modified node tag.
And acquiring a node tag of a second content object corresponding to the first editing content object in the preview window according to the corresponding relation between the first content object of the first electronic book and the second content object of the second electronic book.
And judging that the first edited content object is not positioned between the head and tail sections of the first electronic book, and the editing operation of the first edited content object is not related to the combined head and tail sections in the second electronic book, and the node labels of other second content objects in the second electronic book do not need to be processed, and the node labels of the second content objects can be directly processed correspondingly according to the editing operation. If the editing operation is deleting the content object, correspondingly deleting the node label of the second content object; or, the editing operation is the modification of the content object style, and the node label of the second content object is modified correspondingly according to the style required by the editing operation; or, the editing operation is that the content is set as a text, and the node label of the second content object is modified correspondingly. And finishing the local refreshing of the preview window according to the modified node label.
The first edited content object is judged to be positioned between the head and tail sections of the first electronic book, but the editing operation is not related to the paragraph modification, the editing operation on the first edited content object does not cause the re-splitting of the head and tail sections which are already combined in the second electronic book, the node labels of other second content objects in the second electronic book do not need to be processed, and the node labels of the second content objects can be processed correspondingly directly according to the editing operation. If the editing operation is deleting the content object, correspondingly deleting the node label of the second content object; or, the editing operation is the modification of the content object style, and the node label of the second content object is modified correspondingly according to the style required by the editing operation. And finishing the local refreshing of the preview window according to the modified node label.
Specifically, if a user triggers an editing operation for modifying a content object style of a first content object (picture) of 128 of a first electronic book in an editing window, the editing operation is set to be centered at 100%, the first content object of 128 is located between head and tail sections of the first electronic book, but the editing operation is not associated with section modification, a node tag of a second content object corresponding to the first content object of 128 can be directly acquired for modification, and the second electronic book of the preview window shown in fig. 7 sets the picture to be centered at 100%, without affecting other second content objects. In addition to the above examples, the editing operation triggered by the user in the editing window on the first edited content object of the first electronic book may further include, for example, an editing operation of deleting contents on the picture, the label, the chart and the like, an editing operation of modifying content object style on the picture, the label, the chart and the like, and setting the label and the chart and the like as a text and the like, if the first edited content object is not located between the head and tail sections of the first electronic book, an editing operation of deleting contents on the picture, an editing operation of deleting contents on the label, the chart and the like, a content object style modification on the label and the chart and the like, and the editing operation of the first edited content object triggered above may directly obtain a node tag of the second content object corresponding to the first edited content object in the preview window, and deleting and/or modifying the node label, and finishing the local refreshing of the preview window according to the modified node label.
According to the window partial refresh method provided by the present invention,
