Detailed Description
Example 1
FIG. 1 shows a flow diagram of a method for window partial refresh according to one embodiment of the invention, as shown in FIG. 1, comprising the steps of:
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 proofreading person of a first electronic book, hereinafter referred to as a user) performs an editing operation on the first electronic book, a user interface used includes an editing window in which the first electronic book is displayed and a preview window in 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 typeset electronic book, such as pdf electronic book, and the second electronic book is a streaming typeset electronic book, such as epub electronic book. The first electronic book and the second electronic book display the same content using different typesetting formats.
As shown in fig. 2, the editing window on the left side displays the first electronic book, and the preview window on the right side displays the second electronic book. The preview window may be displayed in a second e-book generated in, for example, html. Specifically, before the user edits the first electronic book, each content object included in the first electronic book is parsed, and a node tag of a second content object of the second electronic book is generated according to the first content object of the first electronic book. And simultaneously, recording the corresponding relation between the first content object of the first electronic book and the second content object of the second electronic book. The first content object and the second content object include content objects such as a title, a paragraph, a picture, a text annotation, caption a legend (picture title, picture annotation, etc.). For the second electronic book, different second content objects respectively correspond to different node labels. If the title uses an h node label, the paragraph uses a p node label, the picture uses an img node label, etc., the description is not limited herein.
In addition to generating node labels of second content objects of the second electronic book according to the first content objects of the first electronic book, the first content objects in the first electronic book need to be processed for reading by readers. As shown in the editing window in fig. 3a, the first content object 122 in the displayed first electronic book is a paragraph, the first content objects 123-125 are annotations, the first content object 128 is a picture, the first content object 129 is a drawing, the first content object 130 is a paragraph, when the first electronic book is actually read, the corresponding paragraph 122 and the corresponding paragraph 130 should be front and rear parts of the same paragraph, but are separated by other content objects in the first electronic book, so as to affect the continuity of reading of readers; or when the front and rear parts of one paragraph in the first electronic book are positioned on two adjacent pages due to page typesetting, displaying the two adjacent pages as different paragraphs in the first electronic book; or when the first electronic book is displayed in a column manner, the front and rear parts of a paragraph are respectively located in different columns, and are 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 one paragraph are respectively displayed as different paragraphs, and the completeness of the paragraphs is affected. Therefore, it is also necessary to identify each paragraph in the first electronic book, and determine whether two adjacent paragraphs in the first electronic book are the first paragraph and the last paragraph respectively. The first segment starts with a normal paragraph and the abnormal paragraph ends, and the tail segment starts with an abnormal paragraph and the normal paragraph ends. The normal paragraph beginning includes a paragraph beginning indentation, such as a beginning line indentation of the normal paragraph, two words, etc., the normal paragraph ending includes an ending punctuation, such as a period, question mark, exclamation mark, downlead mark, etc., the normal paragraph ending ends with an ending punctuation, the paragraph ending will produce an ending indentation that is different from the normal line word length in the paragraph, etc. Judging whether the paragraphs in the first electronic book are first according to the characteristics of the first and the last paragraphs according to the sequence of the paragraphs in the first electronic book, if so, 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 judged to be 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 the first paragraphs, determining that the first electronic book does not have the first and the last paragraphs; if a certain paragraph in the first electronic book is judged to be the first paragraph, whether the next paragraph of the paragraph is the tail paragraph is judged; if yes, determining that two adjacent sections in the first electronic book are a first section and a tail section respectively. Further, the editing window and the preview window can display the corresponding electronic book in the unit of chapters, so that the processing in the unit of chapters is convenient, the range of editing operation is narrowed, the influence of the editing operation is within one chapter, and the content of other chapters is not influenced. When judging whether the first electronic book paragraph is the first paragraph or the last paragraph, the paragraphs in the current chapter of the first electronic book currently displayed in the editing window can be judged, the judging range is reduced, and the processing efficiency is improved.
For the convenience of the reader to read, the contents of the corresponding first and last sections are combined in the second electronic book displayed in the preview window, the contents of the last section are combined to the end of the contents of the first section, and the content of the last section is displayed as a complete section, for example, the section selected by the box in fig. 3b is the combination of the section corresponding to 122 and the section corresponding to 130 in fig. 3 a. The merged paragraph in the second e-book is arranged according to the position of the first paragraph in the first e-book, and for other content objects between the first and the last paragraph, such as the first content object 123-125 in the first e-book, the first content object 128, the first content object 129, is arranged according to the position in the first e-book after the merged paragraph, as shown in fig. 3 b.
After the second electronic book is obtained, the first electronic book is displayed in an editing window, the second electronic book is displayed in a preview window, a user can edit a first content object in the first electronic book in the editing window, and the editing operation can influence the display of the second electronic book in the preview window. In this embodiment, in order to reduce the time for the preview window to display the second electronic book after refreshing the whole second electronic book, partial refreshing is performed on a part of the content objects of the second electronic book affected by the editing operation, so as to reduce the refresh time. 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, it is determined whether the position of the first editing content object is located between the beginning and end segments of the first electronic book, and whether the editing operation is associated with paragraph 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 segment and the ending segment, as shown in fig. 3a, the first content object of 123-125, the first content object of 128, and the first content object of 129 are located between the beginning and ending segments in the first electronic book. Specifically, two paragraphs, which are adjacent to the first editing content object, in the first electronic book may be obtained, and it is determined whether the two paragraphs are a first paragraph and a last paragraph respectively. The specific judgment mode refers to the description of the step S101; or when it is determined in step S101 that the two paragraphs are the first paragraph and the last paragraph respectively, the corresponding marked paragraphs are the first paragraph and the last paragraph, and whether the two paragraphs adjacent to the first editing content object are the first paragraph and the last paragraph respectively is determined according to the marks, which is not limited herein. If it is determined that two paragraphs adjacent to the first editing content object are the first paragraph and the last paragraph, it is further necessary to continuously determine whether the first editing content object is a text annotation or caption drawing, and whether the editing operation is to set the content object as a text. Since the text annotation or caption drawing is not text, unlike the paragraph, the node label in the second electronic book is different from the node label of the paragraph, and the display mode is different. Setting a text note or caption drawing, etc., as a text, will result in an increase in paragraphs, i.e., editing operations can be associated with paragraph modifications. When the first editing content object is located between the first electronic book and the last electronic book, the first electronic book and the last electronic book cannot be directly combined any more because the first electronic book and the last electronic book are set as text, and the display of the first electronic book and the last electronic book needs to be considered to be influenced by the addition of the paragraphs.
When it is determined that the position of the first editing content object is located between the beginning and end segments of the first electronic book and the editing operation is associated with paragraph modification, step S103 is performed.
Step S103, obtaining 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 node labels of the 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, the node label 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 label of the second content object corresponding to the first editing content object in the preview window can be correspondingly obtained.
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, firstly modifying the node label of the second content object corresponding to the first editing content object, and changing the node label into the node label corresponding to the paragraph, thereby realizing the newly added paragraph. Meanwhile, the content of the first section and the content of the tail section which are combined in the second electronic book are required to be split, and for the first section, the content in the node label corresponding to the first section is modified, wherein the content of the tail section which is combined is not contained any more; for the tail section, node labels corresponding to the tail section are required to be added, and the content of the tail section is recorded. After the node labels of the second electronic book are modified, the positions of the modified node labels in the second electronic book are set according to the positions of the first section, the first editing content object and the tail section in the first electronic book, and the local refreshing of the preview window is completed according to the modified node labels. As shown in fig. 4, a first content object of 123 in the left editing window 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 paragraph modification is associated, and the corresponding right preview window modifies the second electronic book, which re-splits the content combined by the beginning segment and the end segment. The frame-selected paragraph in fig. 3b is a combination of the paragraph corresponding to 122 and the paragraph corresponding to 130, and in fig. 5, the combination of the paragraph corresponding to 122 and the paragraph corresponding to 130 is no longer used to generate a node label for the paragraph corresponding to 130, and the content of the paragraph corresponding to 130 is recorded. And setting the positions of node labels in the second electronic book according to the positions of the first content objects in the first electronic books 122, 123 and 130, and finishing the local refreshing of the second electronic book in the preview window according to the modified node labels, wherein the refreshing can be performed based on the node labels in the second electronic book. If the second electronic book is generated by adopting an html language, after the node label of the second electronic book is determined by utilizing an html tree structure, the determined node label can be directly modified, added, deleted and the like, and according to the node label subjected to the tree structure refreshing processing, rendering refreshing of all the node labels is avoided, so that the refreshing time is greatly saved. The foregoing is illustrative, and the specific implementation may be set according to the implementation, and is not limited herein.
Further, the first content object included between the beginning and end segments of the first electronic book further includes a first non-editing content object in addition to the first editing content object. As shown in fig. 4, the first electronic book has a first section 122 corresponding to the first section and a second section 130 corresponding to the second section in the left editing window, and between the first section and the second section, the first content objects including 124, 125, 128, 129 are included in addition to the first editing content object including 123, and these first content objects are first non-editing 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, in addition to obtaining the node label 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 label of the second content object corresponding to the first editing content object of the first electronic book, the node label of the second content object corresponding to the first non-editing content object contained between the head and tail section of the first electronic book in the preview window is required to be obtained. And modifying the node label of the second content object corresponding to the first editing content object according to the editing operation, splitting the combined first section and the tail section in the second electronic book, modifying the node label corresponding to the first section, and adding the node label corresponding to the tail section. And setting the positions of the modified node labels in the second electronic book according to the positions of the first section, the first editing content object, the first non-editing 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. The second electronic book of the preview window is shown in fig. 5, and the positions of the node labels in the second electronic book are set according to the positions of the first content objects in the first electronic books 122, 123, 124, 125, 128, 129 and 130 for refreshing.
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 section and the tail section of the first electronic book and the editing operation is associated with paragraph modification, the node label of the head section and the tail section of the second electronic book corresponding to the head section and the tail section of the first electronic book and the node label 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 section and the tail section of the second electronic book and the node label of the second content object are modified according to the editing operation, and the modified node labels are subjected to local refreshing, so that the local refreshing of the preview window is completed, the time spent for rendering all chapters, paragraphs and the like of the whole second electronic book is reduced, and the rendering efficiency is improved.
Example two
Fig. 6 shows a flow diagram of a window partial refresh method according to another embodiment of the present invention, as shown in fig. 6, the method comprising the steps of:
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, deletion of a content object, modification of a style of the content object, setting of the content object as a body, and the like. Specifically, deleting the content object is deleting the first editing content object in the first electronic book; the modification of the content object style is that the first editing content object in the first electronic book is subjected to font modification, word size modification, picture style modification and the like; the content object is set as a text to change the type of the first editing content object in the first electronic book and modify the first editing content object into a new paragraph.
In step S602, it is determined whether the position of the first editing content object is located between the beginning and end segments of the first electronic book, and whether the editing operation is associated with paragraph modification.
And judging the position of the first editing content object in the first electronic book, judging whether the first editing content object is positioned between the head section and the tail section of the first electronic book, if not, the editing operation of the first editing content object does not influence the change of the head section and the tail section, other first editing content objects do not need to be changed, and only the node label of the second content object corresponding to the first editing content object can be processed, so that the step S603 is executed.
If the position of the first editing content object is judged to be located between the head section and the tail section of the first electronic book, whether the editing operation is associated with paragraph modification is further judged. If the editing operation is content object deletion or content object style modification, the editing operation only modifies the first editing content object when modifying, without affecting other first content objects and without adding paragraphs, then it is determined that the editing operation is not associated with paragraph modification, and step S603 is executed.
Step S603, obtaining a node label of a second content object corresponding to the first editing content object in the preview window, deleting and/or modifying the node label, and finishing local refreshing of the preview window according to the modified node label.
And acquiring the node label of the 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.
Judging that the first editing content object is not located between the head section and the tail section of the first electronic book, and processing node labels of other second content objects in the second electronic book without the combined head section and tail section in the second electronic book in the editing operation of the first editing content object, so that the node labels of the second content objects can be processed directly according to the editing operation. If the editing operation is content object deletion, correspondingly deleting node labels of the second content object; or the editing operation is content object style modification, and the node label of the second content object is correspondingly modified 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 correspondingly modified. And finishing the local refreshing of the preview window according to the modified node label.
Judging that the first editing content object is positioned between the head section and the tail section of the first electronic book, wherein the editing operation is not associated with paragraph modification, the head section and the tail section which are combined in the second electronic book are not required to be split again by the editing operation of the first editing content object, node labels of other second content objects in the second electronic book are not required to be processed, and the node labels of the second content objects can be processed directly according to the editing operation. If the editing operation is content object deletion, correspondingly deleting node labels of the second content object; or the editing operation is content object style modification, and the node label of the second content object is correspondingly modified 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 the user triggers an editing operation of 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 by 100%, the first content object of 128 is located between the first and the last segments of the first electronic book, but the editing operation is not associated with paragraph modification, node labels of a second content object corresponding to the first content object of 128 can be directly obtained to modify, and as shown in fig. 7, the second electronic book of the preview window sets the picture to be centered by 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 editing content object of the first electronic book may further include, for example, the editing operation of the first editing content object triggered by the user in the editing window is not located between the first and second sections of the first electronic book, the editing operation of content deletion on the picture, the label, the caption drawing and the like, the content object style modification on the picture, the label, the caption drawing, the setting of the label and caption drawing as text and the like, or the first editing content object is located between the first and second sections of the first electronic book, the editing operation of content object deletion on the picture, the editing operation of content deletion on the label, the caption drawing and the like, the content object style modification on the label and caption drawing and the like, and the above triggered editing operation of the first editing content object may directly obtain the node label of the second content object corresponding to the first editing content object in the preview window, delete and/or modify the node label, and finish the local refreshing of the preview window according to the modified node label.
According to the window partial refresh method provided by the invention,
