All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
With the rapid development of the mobile internet and the popularization of intelligent devices, more and more intelligent devices have a function of editing documents, for example, an ink screen electronic book reader, which is a device specially used for reading electronic books and generally provided with a stylus pen for users to write and take notes in electronic documents. Along with the popularization of intelligent equipment, a plurality of matched intelligent editing software, such as NeoReader reading software, also come into play. The NeoReader reading software is reading software capable of being applied to an ink screen electronic book reader, can support opening of electronic books in various formats, and can directly edit documents through a handwriting pen after the electronic books are opened. When a user edits an electronic document through document reading software by using a handwriting pen and leaves handwritten note data, the handwritten note data of the user can be identified to be associated with characters, graphs, symbols, formulas and the like through analyzing the handwritten note coordinate data and the pressure data. In addition to writing and taking notes on an electronic document by using a handwriting pen, various types of marks can be made on the electronic document, for example, marks such as highlighting, underlining, wavy underlining, double underlining, dashed underlining and the like can be made on the document; the user may also switch the type of flag. Although both smart reading software and smart reading devices are popular, how to efficiently utilize smart devices and smart reading software to edit electronic documents is still a concern.
Therefore, a document editing method is needed to solve the problem that the electronic document cannot be edited efficiently.
In order to solve the problem, the application provides a document editing method which can be used for solving the problem that the electronic document cannot be efficiently edited.
The method can be applied to any equipment capable of realizing document editing, and optionally, the equipment capable of realizing document editing can be terminals with data processing capability, such as an ink screen e-book reader, a tablet computer, a mobile phone and the like.
The following describes a flow of a document editing method according to an embodiment of the present application with reference to fig. 1, where the flow may include the following steps:
step S101, acquiring handwritten stroke data.
Specifically, in the electronic document, the handwritten stroke data of the user includes coordinates and pressure of all points in the stroke, for example, each point includes data represented by { x, y, size }, where x is an abscissa value, the value range is [0, width of screen ], y is an ordinate value, the value range is [0, height of screen ], size is a pressure value, the value range is [0, pressure maximum value ], a stroke includes n points, and then the data of the stroke is an array of data of the n points in order, for example [ point 1, point 2,.., point n ]. Accordingly, handwritten stroke data may be acquired first for further processing.
And S102, recognizing the handwritten stroke data to obtain a recognition result of the handwritten stroke data.
Specifically, after acquiring the handwritten stroke data, the handwritten stroke data may be recognized by the handwriting recognition processor, and a recognition result and recognized data may be acquired. Wherein the data result after the handwritten stroke data recognition may include:
(1) Type of handwritten stroke data: text, straight line, wavy line, circular, oval, rectangle, polygon, triangle, rhombus, parallelogram, hand drawing graffiti, arrow, arc, the arc of taking the arrow, the straight line of taking the arrow.
(2) Text content associated with the handwritten stroke data.
Step S103, judging whether the recognition result of the handwritten stroke data contains a preset mark symbol.
Specifically, after the recognition result of the handwritten stroke data is obtained, the operation performed on the document may be judged by analyzing the recognition result of the handwritten stroke data. Therefore, after the recognition result of the handwritten stroke data is obtained, whether the recognition result of the handwritten stroke data contains a preset mark symbol or not can be judged. If the recognition result of the handwritten stroke data contains text annotations and preset annotation mark symbols, which indicate that annotation marks need to be added to the document, step S104 may be executed; if the recognition result of the handwritten stroke data includes a preset deletion mark symbol indicating that the existing mark of the document needs to be deleted, step S105 may be executed.
And step S104, adding annotation marks to the document content associated with the handwritten stroke data, wherein the annotation marks comprise annotation mark symbols and text annotations in annotation boxes of the annotation mark symbols.
Specifically, as can be seen from the above steps, if the recognition result of the handwritten stroke data includes a text comment and a preset comment mark symbol, which indicates that a comment mark needs to be added to a document, a comment mark may be added to the document content associated with the handwritten stroke data based on a text comment included in the handwritten stroke data and the document content associated with the handwritten note data, where the comment mark may include a comment mark symbol and a text comment in a comment box of the comment mark symbol.
Step S105, obtaining the target mark corresponding to the deleting mark symbol in the document, and deleting the target mark.
Specifically, it can be seen from the above steps that, if the recognition result of the handwritten stroke data includes a preset deletion marker symbol, it indicates that the existing marker in the document needs to be deleted. And acquiring the target mark corresponding to the deletion mark symbol in the document, and deleting the target mark.
Wherein the deletion marker symbol may be set to the characters "X" or "X", "D".
For example, if the recognition result of the handwritten stroke data is a text, text content included in the recognition result may be further acquired, and if the text content included in the recognition result includes one or more characters, and the characters are any one or more of "X" or "X", "D", and "D", the target mark may be deleted after the target mark is acquired according to the target mark corresponding to the handwritten stroke data existing in the acquired document.
For example, fig. 2 illustrates an effect diagram of quickly deleting a mark already existing in a document, as shown in fig. 2, when a user draws two "X" in an annotation mark already existing in the document with a handwriting pen, and after recognizing the handwriting stroke data, it can be recognized that the handwriting stroke data contains two characters "X", it can be confirmed that a mark corresponding to the character "X" needs to be deleted, and then the target mark can be deleted after acquiring the target mark according to acquiring a target mark corresponding to the handwriting stroke data already existing in the document.
According to the technical scheme, the document editing method provided by the embodiment of the application can realize that when a user edits the electronic document, a handwriting pen can be directly used for adding annotation marks to the selected document content and deleting marks existing in the electronic document; the electronic document can be marked quickly, accurately and efficiently; furthermore, the user can close the function of the hand touch of the reading device, so that the effect of preventing the user from touching by mistake is realized, the efficiency of editing the electronic document is better improved, and the reading experience of the user is improved.
In consideration of the fact that in practical application, when a user wants to delete a mark made on an electronic document after a certain time interval after the user makes the mark on the electronic document, the method and the device can realize the quick deletion of the mark made on the electronic document by the user.
Next, referring to fig. 3, another document editing method that can implement quick deletion of existing marks in an electronic document will be described, which may include the following steps.
Step S201, in the document content related to the handwritten stroke data, the position away from the handwritten stroke data reaches a preset range, and existing marks in the document are searched.
Specifically, after the handwritten stroke data is recognized, whether a mark exists in a document may be found in a document when a position of the document from the handwritten stroke data reaches a preset range in document content associated with the handwritten stroke data, and if the mark exists in the document when the position of the document from the handwritten stroke data reaches the preset range, step S202 may be executed.
Step S202, judging whether the matching degree of the mark existing in the document and the track of the handwritten stroke data reaches a set threshold value.
Specifically, if it is found that a mark exists in the document within a preset range from the position of the handwritten stroke data, it may be further determined whether the matching degree between the mark existing in the document and the track of the handwritten stroke data reaches a set threshold. If it is determined that the matching degree between the existing mark in the document and the trajectory of the handwritten stroke data reaches the predetermined threshold, it indicates that the existing mark in the document and the handwritten stroke data may be repeated mark symbols, and step S203 may be performed.
In step S203, the existing mark found in the document is deleted.
Specifically, as can be seen from the above steps, if it is determined that the matching degree between the existing mark in the document and the trajectory of the handwritten stroke data reaches the predetermined threshold, it indicates that the existing mark in the document and the handwritten stroke data may be repeated mark symbols, and the existing mark found in the document may be deleted.
For example, if it is found that a mark exists in a document within a preset range from the position of the handwritten stroke data, it may be further determined whether the matching degree between the mark existing in the document and the track of the handwritten stroke data reaches a set threshold. If the matching degree of the mark already existing in the document and the track of the handwritten stroke data reaches a set threshold value, the current handwritten stroke data is possibly the repeated mark of the user. Existing tags found in the document may be deleted and the document no longer marked any more for handwritten stroke data.
For example, if the recognition result type of the handwritten stroke data is a freehand scribble, the coordinates (left 1, top 2) of the upper left point of the circumscribed rectangle corresponding to the document content associated with the handwritten stroke data may be obtained as a starting point 1, and the coordinates (right 1, bottom 1) of the upper right point of the circumscribed rectangle corresponding to the document content associated with the handwritten stroke data may be obtained as an ending point 1. Acquiring a character associated with the handwritten stroke data as a starting character A through coordinates of a starting point 1, and acquiring an index corresponding to the character A; and acquiring a character associated with the handwritten stroke data as a starting character B through the coordinates of the end point 1, acquiring an index corresponding to the character B, and assuming that the index corresponding to the character A is 100 and the index corresponding to the character B is 101, determining that the recognition result of the handwritten stroke data is a text content < AB >, the text index range of < AB > is [100,101], and determining the document index range as a preset search range. And searching a matching index range in all marks existing in the document based on the index range [100,101], if the index range matched with the index range [100,101] is searched in all marks existing in the document, and the matching degree of the marks existing in the document and the track of the handwritten stroke data reaches a set threshold, determining that the matching of the marks existing in the document and the track of the handwritten stroke data is successful, acquiring the marks corresponding to the index range [100,101] existing in the document, and deleting the marks.
For example, fig. 4 illustrates an effect diagram of quickly deleting existing marks in a document, as shown in fig. 4, an annotation mark symbol and a handwritten annotation text "× T" having a circumscribed rectangle connected to an arrowed line already exist in the document, after a user repeatedly draws a circumscribed rectangle and an arrowed line in existing annotation marks in the document with a handwriting pen, after confirming that the stroke type of the recognition result of the handwritten stroke data is the handwritten graffiti, that is, recognizing that the user repeatedly draws a circumscribed rectangle and an arrowed line in existing annotation marks of the document, whether an existing mark exists in document contents associated with the handwritten stroke data can be searched for according to a track of the handwritten stroke data as a reference point, and if so, the existing annotation mark in the document can be deleted.
According to the technical scheme, when a user wants to delete the existing mark in the document, the mark which the user wants to delete can be quickly identified and the existing mark in the document can be deleted, and the user does not need to delete the existing mark through the mark deleting function in the menu function after selecting the mark to be deleted. The efficiency of the user for editing the document is further improved.
As can be seen from the above description, if the recognition result of the handwritten stroke data includes a text annotation and a preset annotation mark symbol, an annotation mark is added to the document content associated with the handwritten stroke data, where the annotation mark includes the annotation mark symbol and a text annotation in an annotation box of the annotation mark symbol.
Next, the process is described, which can be implemented in several ways, specifically as follows:
in the first kind of the chemical reaction, the first,
step S301, obtaining the document content associated with the handwritten stroke data.
Specifically, as can be seen from the above description, if the recognition result of the handwritten stroke data includes a text annotation and a preset annotation mark symbol, it indicates that an annotation mark needs to be added to the document content associated with the handwritten stroke data, and therefore, the document content associated with the handwritten stroke data can be obtained. After obtaining the document content associated with the handwritten stroke data, step S302 may be performed.
Step S302, corresponding annotation mark symbols are added to the document content related to the handwritten stroke data.
Specifically, after obtaining the document content associated with the handwritten stroke data, a corresponding annotation mark symbol may be added to the document content associated with the handwritten stroke data.
Step S303, converting the handwritten text annotation into a text annotation in a preset format, and adding the text annotation into an annotation frame of the annotation mark symbol.
Specifically, after adding a corresponding annotation mark symbol to the document content associated with the handwritten stroke data, in order to make the text annotation of the annotation mark look more beautiful and standard, the handwritten text annotation may be converted into a text annotation in a preset format and added into an annotation box of the annotation mark symbol. To accomplish the addition of annotation tags to the document content associated with the handwritten stroke data.
In the case of the second type 2,
step S401, obtaining the document content associated with the handwritten stroke data.
Specifically, the document content associated with the handwritten stroke data may be obtained, and if the recognition result of the handwritten stroke data includes a text annotation and a preset annotation mark symbol, step S402 may be executed.
Step S402, adding corresponding annotation mark symbols to the document content associated with the handwritten stroke data.
Step S403, adding the handwritten text annotation associated with the annotation mark symbol into an annotation box of the annotation mark symbol.
Specifically, after adding the corresponding annotation mark symbol to the document content associated with the handwritten stroke data, if the user wants to directly add the handwritten text annotation to the annotation box of the annotation mark symbol, the handwritten stroke data in the recognition result may be directly added to the annotation box of the annotation mark symbol.
In the case of the (3) rd species,
step S501, obtaining the document content related to the handwritten stroke data.
Specifically, if the recognition result of the handwritten stroke data includes a text annotation and a preset annotation mark symbol, after obtaining the document content associated with the handwritten stroke data, step S502 may be executed.
Step S502, adding corresponding annotation mark symbols to the document content associated with the handwritten stroke data.
Step S503, converting the handwritten text annotation into a text annotation in a preset format and a handwritten text annotation associated with the annotation mark symbol, and adding the text annotation into an annotation box of the annotation mark symbol.
Specifically, if the user only wants to convert a part of the handwritten text annotation into a text annotation in a preset format, and the remaining part of the handwritten text annotation is not converted, the text annotation content converted into the preset format may be added to the annotation box of the annotation mark symbol together with the unconverted handwritten text annotation content. For example, if a user wants to convert a text portion of a handwritten text annotation into a text annotation in a preset format and original handwritten note data of a part of a drawn graph is retained, the handwritten text annotation can be converted into a text annotation in the preset format and a handwritten text annotation associated with the annotation mark symbol and added into an annotation box of the annotation mark symbol.
The preset annotation mark symbol may be: an arc with an arrow and a straight line with an arrow.
When the handwritten stroke data is recognized to contain the preset annotation mark symbol, whether two ends of the document content related to the handwritten stroke data are the preset annotation mark symbol and the handwritten text annotation or not can be judged. And if the two ends of the document content associated with the handwritten stroke data are the preset annotation mark symbol and the handwritten text annotation. The next processing can be performed.
For example, if the type of the predetermined annotation mark symbol included in the recognition result of the handwritten stroke data is a straight line with an arrow, an end coordinate point (x) of the straight line with the arrow may be obtained 1 ,y 1 ) And matching is performed in the handwritten stroke data list. Judging whether the document content associated with the handwritten stroke data has a circumscribed rectangle, if so, judging whether the document content has a circumscribed rectangleIf the document content associated with the writing stroke data contains a circumscribed rectangle, whether the range associated with the circumscribed rectangle contains a coordinate point (x) of a segment of a straight line with an arrow or not is further judged 1 ,y 1 ) Or judging the range and coordinate point (x) associated with the circumscribed rectangle 1 ,y 1 ) Is less than a preset threshold. For example, the preset threshold may be 10 pixels. The preset threshold may be adjusted with reference to the width of the handwritten stroke data so that the accuracy of recognition may be improved. If the range associated with the circumscribed rectangle comprises a coordinate point (x) of a segment of a straight line with an arrow 1 ,y 1 ) Or the range and coordinate point (x) associated with the circumscribed rectangle 1 ,y 1 ) Is less than a preset threshold, it may be determined that the handwritten stroke data content was successfully recognized.
After determining that the handwritten stroke data is successfully recognized, the coordinate point (x) at the other end of the straight line may be taken 2 ,y 2 ) And obtaining a coordinate point (x) 2 ,y 2 ) The corresponding text character. When the coordinate point (x) is acquired 2 ,y 2 ) After the corresponding text character, a coordinate point (x) is obtained 2 ,y 2 ) Character index corresponding to the corresponding text character, e.g. the coordinate point (x) obtained 2 ,y 2 ) If the character index of the corresponding text character is 101, it may be determined in a preset mark list whether a marked text index range in the preset mark list includes a coordinate point (x) 2 ,y 2 ) Corresponding text characters, e.g. having a range of marked-up text indexes of [100,120]The coordinate point (x) obtained 2 ,y 2 ) The character index of the corresponding text character is 101 and falls within the tagged text index range 100,120]Then, it may be confirmed that the identification of the document content associated with the handwritten stroke data is successful, and a straight line with an arrow included in the handwritten stroke data may be further obtained.
After the straight line with the arrow included in the handwritten stroke data is obtained, the handwritten text characters associated with the straight line with the arrow may be further obtained, for example, a recognition result of the handwritten stroke data may be obtained through a handwriting recognition technology, content of a handwritten text annotation associated with the handwritten stroke data may be obtained, the content of the handwritten text annotation may be converted into a text annotation in a preset format, for example, the content of the handwritten text annotation may be converted into a text annotation in a format with a font of song and a font size of small four, and then the text annotation with the font of song and the font size of small four is added into an annotation box of an annotation mark corresponding to the straight line with the arrow. To accomplish the addition of annotation tags to the document content associated with the handwritten stroke data.
For example, fig. 5 illustrates an effect diagram for quickly adding annotation marks to a document, as shown in fig. 5, when a user draws a circumscribed rectangle, a straight line with an arrow, and a handwritten text annotation "× T" in the document with a handwriting pen, it may be confirmed that the recognition result of the handwritten stroke data includes a text annotation and a preset annotation mark symbol, it may be recognized that the recognition result of the handwritten stroke data includes a text annotation as a character "× T", and the annotation mark symbol is a circumscribed rectangle connected by a straight line with an arrow, and after the handwritten text annotation "× T" is converted into a preset format, an annotation mark with a straight line with an arrow connected by a circumscribed rectangle may be added at a document content associated with the handwritten stroke data.
Furthermore, the user can set a corner mark on the annotation mark corresponding to the straight line with the arrow according to requirements, and when the user wants to read the annotation content of the annotation mark, the user can display the annotation content in the form of text by clicking the corner mark. When the user does not want the annotation content of the annotation mark to be displayed in the document, the annotation mark can be folded, and the annotation mark can only show one corner mark symbol and does not show the annotation content of the annotation mark.
According to the technical scheme, when the recognition result of the handwritten stroke data comprises a text annotation and a preset annotation mark symbol, annotation marks can be added to the document content related to the handwritten stroke data according to the requirements of a user. And the annotation mark can be quickly added to the document. The efficiency of document editing is improved.
As can be appreciated from the above description, the present application may determine whether the recognition result of the handwritten stroke data includes a predetermined marker. In an actual application process, if the recognition result of the handwritten stroke data includes a preset insertion mark symbol, the implementation manners of the corresponding document editing methods may also be different, and the process is described next, and the implementation process of the process is specifically as follows:
step S601, obtaining the document content associated with the handwritten stroke data.
Specifically, as can be seen from the above description, if the recognition result of the handwritten stroke data includes a preset insertion mark symbol, it indicates that a mark needs to be inserted into the document. To insert a marker in a document, the document content associated with the handwritten stroke data may be obtained.
Step S602, adding a mark corresponding to the insertion mark symbol to the document content.
Specifically, after obtaining the document content associated with the handwritten stroke data, after further judging the category of the preset inserted mark symbol included in the recognition result of the handwritten stroke data, a mark corresponding to the inserted mark symbol may be added to the document content.
For example, the preset insertion flag symbol may be set as: straight lines, wavy lines, circles, ellipses, rectangles, polygons, triangles, diamonds, parallelograms;
for example, if the preset insertion mark symbol included in the recognition result of the handwritten stroke data is a rectangle, the coordinates (left 12, top 2) of the upper left point of the circumscribed rectangle in the recognition result of the handwritten stroke data may be obtained as a starting point 2, and the coordinates (right 2, bottom 2) of the upper right point of the circumscribed rectangle in the recognition result of the handwritten stroke data may be obtained as an ending point 2; through the coordinate of the starting point 2, the character corresponding to the starting point 2 is obtained as a starting character C, and through the coordinate of the ending point 2, the character corresponding to the ending point 2 is obtained as a starting character D, so that the characters C, D and the characters between the characters D can be determined as the text content < c.. D > included in the recognition result of the handwritten stroke data.
Besides the characters contained in the text content contained in the recognition result of the handwritten stroke data, the index range of all the characters in the document can be obtained. Assuming that the character index range of a document starts from 1, for example, the full text of the document has 1000 characters, all the character ranges of the document are [1,1000]. If the character C is the 100 th character of the document, the index of the character C is 100, and if the character D is the 120 th character, the index of the character D is 120; then the text content < c.. D > corresponds to an index range of [100,120].

Generally, when a text content of a document is underlined, the underlining is generally below the words of the text content. If the text content of the document cannot be acquired at the starting point 3, the correct character can be acquired only by upwards offsetting for a certain distance; therefore, an offset F may be set to adjust the position of the straight line or wavy line contained in the handwritten stroke data, wherein the predetermined offset F may be predetermined to be 5 pixels fixed, or predetermined as described aboveHalf the word size. Both the start point 3 and the end point 3 are shifted upward by a preset shift amount F. Coordinate point (x) corresponding to shifted starting point 3 3 ,y 3 -F), coordinate point (x) corresponding to the end point 3 4 ,y 4 F), the corresponding character can be obtained as the start character E by the shifted coordinates of the start point 3, and the corresponding character can be obtained as the end character F by the shifted coordinates of the end point 3, then the characters E and F and the characters in between can be determined as the obtained text content<E...F>. Underline marks of straight lines or wavy lines are added below the characters E and F and the characters in between.
Further, the user can change the symbol marked by the underline and the color of the symbol marked by the underline according to the requirement. For example, underlining is changed to double underlining straight lines, double underlining wavy lines.
For example, it may be determined whether the recognition result of the handwritten stroke data includes a preset modification mark symbol; the preset modification flag may be set as: it is U or U.
If the recognition result of the handwritten stroke data contains a preset modification mark symbol, searching for an existing mark in the document content associated with the handwritten stroke data within a preset range; if the existing mark is found within the preset range, the mark found in the document can be modified according to the requirement.
It can be seen from the foregoing technical solutions that, in the embodiment of the present application, when the recognition result of the handwritten stroke data includes a preset insertion mark symbol, a corresponding mark may be inserted at a document content associated with the handwritten stroke data. Further, when the recognition result of the handwritten stroke data contains a preset modification mark symbol, the mark existing in the document can be searched in a preset range and modified. The document editing can be completed quickly, and the document editing efficiency is improved.
For example, a preset mark menu is popped up above the text content related to the mark, two touch blocks capable of being dragged are displayed at the head and the tail of the related text content, a user adjusts the text selection content by dragging the two touch blocks forwards or backwards, and finally, a change mark icon on the menu is clicked to finish changing the text content related to the mark.
