Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to improve user experience, embodiments of the present invention provide a method and an apparatus for storing annotation data, an electronic device, a computer-readable storage medium, and a computer program product.
The annotation data in the embodiment of the present invention may be annotation data in a page such as an electronic whiteboard, and may also be annotation data in a page such as a PPT, where a specific type of the annotation page where the annotation data is located is not limited.
Referring to fig. 1, fig. 1 is a schematic flow chart of a method for storing annotation data according to an embodiment of the present invention, which specifically includes the following steps:
Further, the annotation data to be saved may be all annotation data in the annotation page, or may also be specified annotation data in the annotation page, for example, the annotation data to be saved may be annotation data in a specified frame selection area selected by a user in the annotation page through a mouse frame selection or a touch frame selection.
The number of the annotation pages in this step may be one or more.
This step may be performed after detecting a save instruction of the user for the annotation data to be saved, for example: and when detecting that the user selects the specified annotation data in the specified area as the annotation data to be saved in a frame selection mode and clicks the annotation saving icon in the interface, acquiring the position information corresponding to the annotation data to be saved.
The position information corresponding to the annotation data to be saved may be position information of each pixel point where the annotation data to be saved is located, and after the position information of each pixel point where the annotation data to be saved is located is obtained, the obtained position information may be stored in a document in a specified format in the subsequent step 103.
When the annotation data to be saved is annotation data with attributes such as color, thickness and the like, if the annotation data is displayed only according to the position information, the attributes such as color, thickness and the like of the annotation data cannot be displayed, and therefore, further, the pixel value information of each pixel point where the annotation data to be saved is located can be obtained, the pixel value information of each pixel point where the annotation data to be saved is located can be stored in the document with the specified format, and when the document with the specified format including the pixel value information and the position information of each pixel point where the annotation data is located is imported into the software for generating the annotation data, the displayed annotation data is the annotation data with attributes such as color, thickness and the like, and therefore, user experience can be further improved.
And 102, acquiring a picture corresponding to the annotation data to be stored.
In the embodiment of the present invention, after a storage instruction of a user for annotation data to be stored is detected, step 101 may be executed first to obtain position information corresponding to the annotation data to be stored, or step 102 may be executed first to obtain a picture corresponding to the annotation data to be stored, and the execution sequence of step 101 and step 102 is not limited.
When the annotation data to be stored is stored and distributed in a plurality of annotation pages, the images corresponding to the annotation data to be stored in each annotation page can be obtained page by page according to the sequence from front to back.
Preferably, in this step, the above-mentioned picture can be obtained in two ways:
the first mode is as follows: and drawing a picture corresponding to the annotation data to be stored according to the position information.
By adopting the first mode, the picture corresponding to the annotation data to be saved can be obtained by drawing in a data rendering mode based on the position information acquired in the step 101.
The second mode is as follows: and performing screenshot operation on the area where the annotation data to be saved is located to obtain a picture corresponding to the annotation data to be saved.
Specifically, when the annotation data to be saved is all annotation data in the annotation page, an Application Programming Interface (API) for performing screenshot operation in the system may be directly called to perform whole page screenshot on the annotation page, so as to obtain a picture corresponding to the annotation data to be saved; when the comment data to be saved is the specified comment data framed and selected by the user in the comment page, the API can be called to obtain the picture corresponding to the specified comment data to be saved based on the position information of the selection frame.
When the annotation data to be saved is all the annotation data in the annotation page, the second mode is adopted to obtain the pictures including the annotation data to be saved and all the original contents in the annotation page, for example, when the annotation data to be saved is all the annotation data in a certain electronic whiteboard software page and the electronic whiteboard software page has a background element or a background color, the second mode is adopted to obtain all the annotation data in the electronic whiteboard software page and simultaneously include all the background elements or the background color of the electronic whiteboard software page, and for example, when the annotation data to be saved is all the annotation data in a certain page and the PPT page has original data (data already existing in the PPT page before the annotation data is generated), the second mode is adopted to obtain all the annotation data in the PPT page, and also pictures of all the original data of the PPT page.
When the annotation data to be stored is the designated annotation data in the annotation page, the picture including the annotation data to be stored and the original content in the designated area where the designated annotation data in the annotation page is located can be obtained in the second mode. For example, when the annotation data to be stored is specified annotation data in a certain electronic whiteboard software page, and the electronic whiteboard software page has a background element or a background color, a first manner may be adopted to obtain the specified annotation data in the electronic whiteboard software page, and also include a picture of the background element or the background color in a specified area where the specified annotation data in the electronic whiteboard software page is located.
In this step, the storage location of the picture may be after the storage location of the position information or before the storage location of the position information in the same document, and the front-back relationship between the storage locations of the picture and the position information in the same document is not limited herein.
When the annotation data to be saved are distributed on a plurality of different annotation pages, the position information and the picture corresponding to the annotation data to be saved in each annotation page can be stored according to the order of the annotation pages, for example: when the annotation data to be stored is distributed on 2 different annotation pages, the picture corresponding to the annotation data to be stored in the first annotation page may be stored first, then the picture corresponding to the annotation data to be stored in the second annotation page may be stored sequentially, and after all the pictures are stored, the position information corresponding to the annotation data to be stored in the first annotation page and the position information corresponding to the annotation data to be stored in the second annotation page may be stored sequentially after the picture storage positions are reached.
Further, the specified format may be any one of the following formats: a portable document format PDF, a DOC format, a JPG format, a JPEG format, a PNG format, or an image interchange format GIF, or the like. Accordingly, the document editing software is software having a picture display function in addition to target software for generating annotation data such as electronic whiteboard software, and specifically, for example, when the specified format is a PDF format, the document editing software may be software (PDF reader) having a PDF document editing function; when the specified format is the DOC format, the document editing software can be common office software; when the specified format is a JPG format, JPEG format, PNG format, or GIF format, the document editing software may be a picture reader.
Further, when the specified format is a non-picture format, for example: in the formats of PDF, DOC, etc., the picture and the position information may be stored in the same document in the specified format as follows:
newly building a document with a specified format;
writing the pictures into the document with the specified format;
writing the position information into the document with the specified format, wherein the position information is positioned behind the picture in the document with the specified format;
or, when the specified format is a picture format, for example: in the format of JPG, JPEG, PNG, GIF, or the like, the picture and the position information may be stored in the same document in the specified format as follows:
and writing the position information into the document corresponding to the picture, wherein the position information is positioned behind the picture in the document corresponding to the picture.
As can be seen from the above embodiments, in the embodiments of the present invention, the position information corresponding to the annotation data to be saved and the picture corresponding to the annotation data to be saved are stored in the same document in the specified format, so that the picture corresponding to the annotation data to be saved can be displayed in other software having a picture display function except for target software such as electronic whiteboard software which generates the annotation data, and when the saved annotation data is to be viewed, the user can view the specific annotation data by displaying the picture corresponding to the saved annotation data by other software having a picture display function except for the target software such as document editing software, and thus, when the user sends the saved annotation data to another person, even if the target software is not installed in the electronic device used by another person, the picture corresponding to the saved annotation data can be displayed by other software having a picture display function except for the target software, to view annotation data, namely: the viewer can more conveniently view the annotation data, and therefore user experience is improved.
In addition, in the embodiment of the present invention, in the same document in the specified format, the annotation data is doubly stored in two different ways: one is as follows: storing position information corresponding to the comment data to be stored, and when a user needs to re-edit the edited comment data, re-displaying the edited comment data in target software generating the comment data to be stored according to the stored position information so that the user can erase, move and the like the edited comment data; the other is as follows: and storing the picture corresponding to the annotation data to be stored, and when the user only wants to check the annotation data without editing the annotation data again, opening the document in the specified format in other software with a picture display function except the target software, and then directly checking the picture stored in the document without opening the target software, so that the use experience of the user is further improved.
Referring to fig. 2, fig. 2 is another schematic flow chart of the annotation data storage method provided in the embodiment of the present invention, which specifically includes the following steps:
Further, the annotation data to be saved may be all annotation data in the annotation page, or may also be specified annotation data in the annotation page, for example, the annotation data to be saved may be annotation data in a specified frame selection area selected by a user in the annotation page through a mouse frame selection or a touch frame selection.
The number of the annotation pages in this step may be one or more.
This step may be performed after detecting a save instruction of the user for the annotation data to be saved, for example: and when detecting that the user selects the specified annotation data in the specified area as the annotation data to be saved in a frame selection mode, and clicking an annotation saving icon in the interface, performing screenshot operation on the area where the annotation data to be saved is located, and obtaining a picture corresponding to the annotation data to be saved.
When the annotation data to be saved are stored on a plurality of annotation pages, the screenshot operation can be performed page by page according to the sequence from front to back so as to obtain the picture corresponding to the annotation data to be saved in each annotation page.
Specifically, when the annotation data to be saved is all annotation data in the annotation page, an Application Programming Interface (API) for performing screenshot operation in the system may be directly called to perform whole page screenshot on the annotation page, so as to obtain a picture corresponding to the annotation data to be saved; when the comment data to be saved is the specified comment data framed and selected by the user in the comment page, the API can be called to obtain the picture corresponding to the specified comment data to be saved based on the position information of the selection frame.
When the annotation data to be saved is all the annotation data in the annotation page, the picture including the annotation data to be saved and all the original contents in the annotation page can be obtained through the step, for example, when the annotation data to be saved is all the annotation data in a certain electronic whiteboard software page and the electronic whiteboard software page has background elements or background colors, all the annotation data in the electronic whiteboard software page and the picture including all the background elements or background colors of the electronic whiteboard software page can be obtained through the step.
When the annotation data to be stored is the designated annotation data in the annotation page, the picture including the annotation data to be stored and the original content of the designated annotation data in the annotation page in the designated area can be obtained through the step. For example, when the annotation data to be stored is specified annotation data in a certain electronic whiteboard software page, and the electronic whiteboard software page has a background element or a background color, the specified annotation data in the electronic whiteboard software page may be obtained through this step, and at the same time, a picture including the background element or the background color in a specified area where the specified annotation data in the electronic whiteboard software page is located may also be obtained.
Specifically, for example, the document of the specified format may be in a portable document format PDF, DOC format, or the like.
The document in the specified format contains an end-of-document identifier, which is used to read the document data before the end-of-document identifier when the document editing software supporting the specified format opens the document in the specified format, for example, the end identifier in the document in the PDF format may be: % EOF.
And 204, acquiring position information corresponding to the annotation data to be stored.
The position information corresponding to the annotation data to be saved can be the position information of each pixel point where the annotation data to be saved is located.
It should be noted that, here, for step 202, after step 201 is executed, step 202 may be executed to newly create a document in a specified format, or after a save instruction for the annotation data to be saved is detected, step 202 may be executed to newly create a document in a specified format; for step 204, after step 201, step 202, and step 203 are executed, step 204 may be executed to obtain the position information corresponding to the annotation data to be saved, or step 204 may be executed after a saving instruction for the annotation data to be saved is detected. In the embodiment of the present invention, the execution order of step 201, step 202, and step 204 is not limited, and it is only required to ensure that step 201, step 202, and step 204 are executed after a storage instruction for annotation data to be stored is detected.
Furthermore, the document with the specified format contains an annotation starting identifier and an annotation ending identifier, and the position information is stored between the annotation starting identifier and the annotation ending identifier in the document with the specified format;
the position information is used for displaying the annotation data according to the position information between the annotation starting identifier and the annotation ending identifier when the document in the specified format is imported into the software for generating the annotation data to be stored. Specifically, when a user wants to perform editing operations such as erasing and moving on stored annotation data, the document in the specified format can be imported into software for generating the annotation data, so that position information can be quickly located according to an annotation starting identifier and an annotation ending identifier in the document, then each pixel point in a software page where the annotation data is located can be determined according to the position information, and then the annotation data can be displayed in a software interface for the user to edit in a mode of setting the pixel value of each pixel point as a preset value.
When the annotation data to be saved is annotation data with attributes such as color, thickness, and the like, if the annotation data is displayed only according to the position information, the attributes such as color, thickness, and the like of the annotation data cannot be displayed, and therefore, further, the pixel value information of each pixel point where the annotation data to be saved is located can be obtained, and the annotation starting identifier and the annotation ending identifier can be stored: and the pixel value information of each pixel point where the annotation data is located is to be stored, so that when the document in the specified format including the pixel value information and the position information of each pixel point where the annotation data is located is imported into the software for generating the annotation data, after each pixel point in the software page where the annotation data is located is determined according to the position information, the determined pixel value of each pixel point can be set according to the pixel value information in the document so as to restore the attributes of the annotation data, such as color, thickness and the like.
Further, the data format of the position information in the document in the specified format may be a JSON (javascript object Notation) format. Under the condition that the pixel value information of each pixel point where the annotation data to be saved is required to be acquired and stored, the data format of the pixel value information stored in the document with the specified format can also be the JSON format.
Because the JSON adopts a text format completely independent of a programming language to store and represent data, the data is easy to analyze and generate, and the data stored in the JSON form is easier to transmit through a network, in the embodiment of the invention, the position information is stored in the document with the specified format in the JSON form, so that the storage efficiency of the annotation data can be improved, and the network transmission efficiency can be improved in the annotation transmission process.
In the embodiment shown in fig. 2, the position information corresponding to the annotation data to be saved and the picture corresponding to the annotation data to be saved are stored in the same document in a specified format, so that the picture corresponding to the annotation data to be saved can be displayed in other software having a picture display function except for target software such as electronic whiteboard software which generates the annotation data, when the saved annotation data is to be viewed, the user can view the specific annotation data by displaying the picture corresponding to the saved annotation data by other software having a picture display function except for the target software such as document editing software, and then when the user sends the saved annotation data to him, even if the target software is not installed in the electronic device used by the other person, the picture corresponding to the saved annotation data can be displayed by other software having a picture display function except for the target software, to view annotation data, namely: the viewer can more conveniently view the annotation data, and therefore user experience is improved.
Meanwhile, in the document with the specified format, the user can check the data content before the document end identifier through the document editing software, and the data content after the document end identifier is invisible to the user, so that the user can only display the picture corresponding to the annotation data to be saved to the user and hide the position information in a mode of writing the picture corresponding to the annotation data to be saved in front of the document end identifier in the document with the specified format and writing the position information in back of the document end identifier in the document with the specified format, thereby reducing the visual interference of the user in the checking process of the annotation data, and further improving the user experience.
In addition, in the embodiment of the present invention, in the same document in the specified format, the annotation data is doubly stored in two different ways: one is as follows: storing the picture corresponding to the annotation data to be stored, and when a user only wants to view the annotation data without editing the annotation data again, opening the document in the specified format in other software with a picture display function except the target software, and then directly viewing the picture stored in the document without opening the target software; the other is as follows: the position information corresponding to the comment data to be saved is stored, and when a user needs to re-edit the edited comment data, the edited comment data can be re-displayed in the target software generating the comment data to be saved according to the stored position information, so that the user can conveniently erase, move and the like the edited comment data, and therefore the use experience of the user is further improved.
Moreover, because the document with the specified format contains the annotation starting identifier and the annotation ending identifier, and the position information is stored between the annotation starting identifier and the annotation ending identifier in the document with the specified format, when the document with the specified format is imported into software for generating annotation data, the position information can be quickly positioned according to the annotation starting identifier and the annotation ending identifier in the document so as to perform a subsequent annotation data display process, and therefore, the efficiency of displaying the annotation data according to the position information can be improved.
Based on the same inventive concept, according to the annotation data storage method provided in the above embodiment of the present invention, correspondingly, an embodiment of the present invention further provides an annotation data storage device, a schematic structural diagram of the device is shown in fig. 3, and the annotation data storage device includes:
the position information acquiring module 301 is configured to acquire position information corresponding to annotation data to be stored;
a picture obtaining module 302, configured to obtain a picture corresponding to the annotation data to be saved;
