Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to improve user experience, the embodiment of the invention provides an annotation data storage method, an annotation data storage device, electronic equipment, a computer readable storage medium and a computer program product.
The annotation data in the embodiment of the invention can be the annotation data in pages such as an electronic whiteboard and the like, and also can be the annotation data in pages such as a PPT and the like, and the 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:
step 101, obtaining position information corresponding to annotation data to be saved.
Further, the annotation data to be saved may be all the annotation data in the annotation page, or may 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, etc.
The number of annotating pages in this step may be one or more.
This step may be performed after detecting a save instruction by the user for the annotation data to be saved, for example: when the fact that the specified annotation data in the specified area is selected as the annotation data to be saved by the user through a frame selection mode is detected, and the annotation saving icon in the interface is clicked, position information corresponding to the annotation data to be saved is obtained.
The location information corresponding to the annotation data to be saved may be the location information of each pixel where the annotation data to be saved is located, after the location information of each pixel where the annotation data to be saved is located is obtained, the obtained location information may be stored in a document with a specified format in a subsequent step 103, so when a user wants to perform editing operations such as erasing and moving on the saved annotation data, the document with the specified format may be imported into software for generating the annotation data, and the annotation data may be displayed for editing by the user according to the location information stored in the document with the specified format.
When the annotation data to be saved is the annotation data with the attributes of color, thickness and the like, if the annotation data is displayed only according to the position information, the attributes of the color, thickness and the like of the annotation data cannot be displayed, so 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 also stored in the document with the specified format, and when the document with the specified format including the pixel value information of each pixel point where the annotation data is located and the position information is imported into the software for generating the annotation data, the displayed annotation data is the annotation data with the attributes of color, thickness and the like, and therefore, the user experience can be further improved.
Step 102, obtaining a picture corresponding to the annotation data to be saved.
In the embodiment of the present invention, after detecting a save instruction of a user for to-be-saved annotation data, step 101 may be performed first to obtain location information corresponding to the to-be-saved annotation data, or step 102 may be performed first to obtain a picture corresponding to the to-be-saved annotation data, and the execution sequence of step 101 and step 102 is not limited.
When the annotation data to be saved are distributed on a plurality of annotation pages, the pictures corresponding to the annotation data to be saved in each annotation page can be acquired page by page according to the sequence from front to back.
Preferably, in this step, the above-mentioned picture may be obtained by the following two methods:
the first way is: and drawing a picture corresponding to the annotation data to be saved according to the position information.
In the first manner, based on the position information acquired in the step 101, a picture corresponding to the annotation data to be saved can be drawn in a data rendering manner.
The second way is: and performing screenshot operation on the region where the annotation data to be stored is located to obtain a picture corresponding to the annotation data to be stored.
Specifically, when the annotation data to be saved is all the annotation data in the annotation page, an API (Application Programming Interface, application program interface) for performing screenshot operation in the system can be directly called to perform whole page screenshot on the annotation page, so that a picture corresponding to the annotation data to be saved is obtained; when the annotation data to be saved is the appointed annotation data selected by the user frame in the annotation page, the API can be called based on the position information of the selection frame to obtain the picture corresponding to the appointed annotation data to be saved.
When the to-be-saved annotation data is all the annotation data in the annotation page, a second mode is adopted to obtain a picture including the to-be-saved annotation data and all the original contents in the annotation page, for example, when the to-be-saved annotation data is all the annotation data in a certain electronic whiteboard software page and the electronic whiteboard software page has background elements or background colors, a second mode is adopted to obtain a picture including all the annotation data in the electronic whiteboard software page and also including all the background elements or background colors of the electronic whiteboard software page, for example, when the to-be-saved annotation data is all the annotation data in a certain PPT page and the PPT page has original data (data already existing in the PPT page before the annotation data is generated), a second mode is adopted to obtain a picture including all the annotation data in the PPT page and also including all the original data of the PPT page.
When the annotation data to be saved is the specified annotation data in the annotation page, the second mode is adopted to obtain the picture comprising the annotation data to be saved and the original content in the specified area where the specified annotation data in the annotation page is located. For example, when the annotation data to be saved 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 first mode is adopted to obtain the image including the specified annotation data in the electronic whiteboard software page and also including the background element or the background color in the specified area where the specified annotation data is located in the electronic whiteboard software page, and for example, when the annotation data to be saved is the specified annotation data in a certain PPT 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 the image including the specified annotation data in the PPT page and also including the original data in the specified area where the specified annotation data is located in the PPT page.
And step 103, storing the picture and the position information into the same document in a specified format.
In this step, in the same document, the storage position of the picture may be subsequent to the storage position of the position information or may be preceding to the storage position of the position information, and here, the relationship between the picture and the storage position of the position information in the same document is not limited.
When the annotation data to be saved is distributed in a plurality of different annotation pages, the position information and the pictures corresponding to the annotation data to be saved in each annotation page can be stored according to the sequence of the annotation pages, for example: when the to-be-saved annotating data are distributed in 2 different annotating pages, the pictures corresponding to the to-be-saved annotating data in the first annotating page can be stored first, then the pictures corresponding to the to-be-saved annotating data in the second annotating page are sequentially stored, and after all the pictures are stored, the position information corresponding to the to-be-saved annotating data in the first annotating page and the position information corresponding to the to-be-saved annotating data in the second annotating page are sequentially stored after the picture storage positions are completed.
Further, the specified format may be any one of the following formats: portable document format PDF, DOC format, JPG format, JPEG format, PNG format, or image interchange format GIF, etc. Accordingly, the document editing software is software having a picture display function other than the target software for generating annotation data such as electronic whiteboard software, and specifically, for example, when the specified format is PDF format, the document editing software may be software having a PDF document editing function (PDF reader); when the designated format is DOC format, the document editing software can be common office software; when the specified format is a JPG format, a JPEG format, a PNG format, or a 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 above specified format by:
newly creating a document in a specified format;
writing the picture into the document in 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;
alternatively, when the specified format is a picture format, for example: JPG, JPEG, PNG or GIF, the picture and the position information may be stored in the same document in the above specified format by:
and writing the position information into a 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 foregoing embodiments, in the embodiment 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 besides the target software that generates the annotation data such as electronic whiteboard software, 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 such as document editing software, so that when the saved annotation data is sent to the user, even if the target software is not installed in the electronic device used by the user, the user can view the annotation data by displaying the picture corresponding to the saved annotation data by other software having a picture display function other than the target software, that is: therefore, the viewer can more conveniently view the annotation data, and user experience is improved.
In addition, in the embodiment of the invention, in the same document with a specified format, annotation data is doubly stored in two different modes: a kind of is: storing position information corresponding to the annotation data to be saved, and redisplaying the edited annotation data in target software for generating the annotation data to be saved according to the stored position information when a user needs to reedit the edited annotation data, so that the user can erase, move and the like the edited annotation data; the other is: when the user only wants to check the annotation data and does not need to edit the annotation data again, the document with the specified format can be opened in other software with the picture display function except the target software, then the stored picture is directly checked without opening the target software, and therefore the use experience of the user is further improved.
Referring to fig. 2, fig. 2 is another flow chart of a method for storing annotation data according to an embodiment of the present invention, which specifically includes the following steps:
and step 201, performing screenshot operation on the region where the annotation data to be stored is located, and obtaining a picture corresponding to the annotation data to be stored.
Further, the annotation data to be saved may be all the annotation data in the annotation page, or may 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, etc.
The number of annotating pages in this step may be one or more.
This step may be performed after detecting a save instruction by the user for the annotation data to be saved, for example: when the fact that the specified annotation data in the specified area is selected as the annotation data to be saved by the user through a frame selection mode is detected, and after an annotation saving icon in an interface is clicked, screenshot operation is carried out on the area where the annotation data to be saved is located, and a picture corresponding to the annotation data to be saved is obtained.
When the to-be-saved annotation data are distributed on a plurality of annotation pages, screenshot operation can be carried out page by page according to the sequence from front to back so as to obtain pictures corresponding to the to-be-saved annotation data in each annotation page.
Specifically, when the annotation data to be saved is all the annotation data in the annotation page, an API (Application Programming Interface, application program interface) for performing screenshot operation in the system can be directly called to perform whole page screenshot on the annotation page, so that a picture corresponding to the annotation data to be saved is obtained; when the annotation data to be saved is the appointed annotation data selected by the user frame in the annotation page, the API can be called based on the position information of the selection frame to obtain the picture corresponding to the appointed annotation data to be saved.
When the annotation data to be saved is all the annotation data in the annotation page, the picture comprising 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, the picture comprising all the annotation data in the electronic whiteboard software page and also comprising 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 saved is the specified annotation data in the annotation page, the image comprising the annotation data to be saved and the original content in the specified area where the specified annotation data in the annotation page is located can be obtained through the step. For example, when the annotation data to be saved 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 image including the specified annotation data in the electronic whiteboard software page and the background element or the background color in the specified area where the specified annotation data is located in the electronic whiteboard software page can be obtained through the step.
Step 202, newly creating a document in a specified format.
Specifically, for example, the document of the specified format may be a portable document format PDF, a DOC format, or the like.
A document of a specified format contains a document end identifier for causing document data before the document end identifier to be read when document editing software supporting the specified format opens the document of the specified format, for example, the end identifier in a document of a PDF format may be: % EOF.
Step 203, the picture is written in the document in the specified format before the document end identifier.
Step 204, obtaining the position information corresponding to the annotation data to be saved.
The position information corresponding to the annotation data to be saved may be the position information of each pixel point where the annotation data to be saved is located.
It should be noted that, for step 202, the document with the specified format may be newly created in step 202 after step 201 is performed, or the document with the specified format may be newly created in step 202 after the save instruction for the annotation data to be saved is detected; for step 204, step 204 may be performed after step 201, step 202, and step 203 are performed, or step 204 may be performed after a save instruction for the annotation data to be saved is detected, where the position information corresponding to the annotation data to be saved is acquired. In the embodiment of the present invention, the execution sequence of step 201, step 202, and step 204 is not limited, and it is only necessary to ensure that step 201, step 202, and step 204 are executed after detecting a save instruction for annotation data to be saved.
Step 205, the position information is written into the document in the specified format after the document end identifier.
Further, the document in the specified format contains an annotation start identifier and an annotation end identifier, and the position information is stored between the annotation start identifier and the annotation end identifier in the document in the specified format;
the position information is used for displaying annotation data according to the position information between the annotation start identifier and the annotation end identifier when the document in the specified format is imported into 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 rapidly positioned according to an annotation start identifier and an annotation end identifier in the document, then each pixel point in a software page where the annotation data are located can be determined according to the position information, and then the annotation data can be displayed in a software interface for editing and using by setting the pixel value of each pixel point as a preset value.
When the annotation data to be saved is annotation data with properties of color, thickness and the like, if the annotation data is only displayed according to the position information, the properties of the annotation data such as the color, the thickness and the like cannot be displayed, so further, pixel value information of each pixel point where the annotation data to be saved is located can be obtained, and the pixel value information can be stored between an annotation start identifier and an annotation end identifier: and storing the pixel value information of each pixel point where the annotation data is located, so that when a document in a specified format comprising the pixel value information and the position information of each pixel point where the annotation data is located is imported into software for generating the annotation data, after each pixel point in a software page where the annotation data is located is determined according to the position information, the pixel value of each determined pixel point can be set according to the pixel value information in the document so as to restore the color, thickness and other attributes of the annotation data.
