@property(nonatomIc，strong)NSArray*pointArray。
the conference equipment establishes a data model in the memory based on the preset data structure, and for each attribute in the data model, some default data can be filled, such as default stroke line width, stroke color and the like.
Step S20, whiteboard data generated based on the electronic whiteboard is acquired, and the whiteboard data is filled into the data model to obtain whiteboard model data;
the conference equipment acquires whiteboard data generated based on the electronic whiteboard, and fills the whiteboard data into the data model to obtain whiteboard model data. The whiteboard data generated based on the electronic whiteboard may include picture data inserted into a current display page of the electronic whiteboard, stroke data of writing, a document opened in the electronic whiteboard, and the like. And the conference equipment fills the whiteboard data into the data model according to the corresponding attributes to obtain whiteboard model data.
Specifically, the whiteboard template data includes picture model data and stroke model data, the whiteboard data includes picture data and stroke data, and step S20 includes:
step S201, filling the picture data into a picture model in the data model to obtain the picture model data, and filling the stroke data into a stroke model in the data model to obtain the stroke model data.
When the conference equipment detects an operation of inserting a picture into a current page of the electronic whiteboard, picture data of the picture to be inserted, such as the size of the picture, information of each pixel point in the picture and the like, is acquired, the picture data is filled into a picture model in the data model, specifically, each data in the picture data is correspondingly filled into the picture model according to attributes, and picture model data is acquired. The data model established based on the preset data structure comprises a picture model used for storing picture basic information, such as information of each pixel point of the picture, a zoom coefficient of the picture, a rotation angle of the picture and the like.
When the conference equipment detects stroke operation triggered based on the electronic whiteboard display interface, stroke data corresponding to the stroke operation, such as coordinate positions of all points in the stroke on a screen, width and color of the stroke, are obtained, and the conference equipment fills the stroke data into a stroke model in the data model to obtain stroke model data. The data model established based on the preset data structure comprises a stroke model used for storing stroke basic information, including the line width of the stroke, the color of the stroke, the point coordinate information contained in the stroke, the ID identification of the stroke and the like.
It should be noted that, in the process of a user operating the display content in the electronic whiteboard display interface, such as adding a page, deleting a page, inserting a picture, rotating a picture, writing a stroke, deleting a stroke, and the like, the conference device updates the data of each attribute in the data model according to the user operation, and therefore, the whiteboard model data is updated based on the user operation.
And step S30, when a file storage instruction is detected, sorting the whiteboard model data according to a preset filing sequence and storing the whiteboard model data as a file in a target format.
An operation menu can be set in the electronic whiteboard display interface, wherein a control for a user to save files is set, and the user can trigger a file saving instruction for saving the files based on the control at any time. In addition, the conference device can also store the files under construction in the electronic whiteboard according to a preset frequency, so as to avoid the loss of the files under construction of the user caused by equipment failure.
When the conference equipment detects a file storage instruction, the whiteboard model data are sorted according to a preset filing sequence, and the sorted whiteboard model data are stored as a file in a target format. The preset filing sequence may be a preset sequence, and is used to specify an arrangement sequence of data of each attribute in the whiteboard model data. The target format may be a predefined file format, and the suffix name of the format is distinguished from the suffix name of the existing file format, so that when the conference device opens the file of the target format, the conference device can recognize that the file is the file of the target format according to the suffix name of the file, and call an electronic whiteboard in the conference device to open the file of the target format. Specifically, the conference device sorts the data of each attribute in the whiteboard model data according to a preset filing sequence, writes the sorted whiteboard model data into the hard disk, and stores the whiteboard model data as a file in a target format, that is, the suffix name of the file is the suffix name of the target format. It should be noted that the files in the target format that are sorted according to the preset filing order and are finally stored are binary files, which increases the security of data and prevents human tampering.
Further, when the conference equipment opens a file in a target format, an electronic whiteboard is called to open the file, specifically, the electronic whiteboard is started, a data model is established according to a preset data structure, data of each attribute is extracted from file contents one by one according to a preset filing sequence, the data of each attribute is filled into the data model to obtain whiteboard model data, and based on the whiteboard model data of the current page, the content of the current page is rendered into a display interface, so that the opening and displaying processes of the file in the target format are realized.
In this embodiment, when it is detected that the electronic whiteboard is started, a data model is established according to a preset data structure, whiteboard data generated based on the electronic whiteboard is acquired, the whiteboard data is filled into the data model to obtain whiteboard model data, when a file storage instruction is detected, the whiteboard model data is stored as a file in a target format after being sorted according to a preset filing sequence, various data generated based on the electronic whiteboard are organized according to a unified data model and sorted and stored according to a specific filing sequence, and unified and safe storage of the data and the file generated in the video conference is realized.
Further, based on the first embodiment, a second embodiment of the conference file processing method according to the present invention provides a conference file processing method. In this embodiment, before the step S20, the method further includes:
step S40, when detecting the instruction of displaying the target file in the electronic whiteboard, detecting whether the target file is a file in a picture format;
an operation menu can be set in a display interface of the electronic whiteboard, a control for a user to open a file is set in the operation menu, the user can trigger an instruction for opening (namely showing) a certain file in the electronic whiteboard based on the control, and the file can be a file in a picture format, such as a file in JPEG and PNG formats, and can also be a file in a document format, such as a file in PDF and WORLD formats. When the conference equipment detects an instruction for displaying a target file in the electronic whiteboard, whether the target file is a file in a picture format is detected, specifically, a suffix name in a file name of the target file can be detected, and the format of the target file is judged according to the suffix name.
And step S50, when the target file is not a file in a picture format, converting the target file into a picture according to the file content, and importing the picture into the electronic whiteboard.
When the target file is detected not to be a file in a picture format, the conference equipment converts the target file into a picture according to the file content and guides the picture into the electronic whiteboard. Specifically, tool software for converting a file in a document format into a picture can be pre-installed in the conference device, when a target file needs to be converted into the picture, the tool software is called to convert, the picture successfully converted by the tool software is obtained, the picture is imported into the electronic whiteboard, the picture data of the picture is filled into the data model, and the picture is rendered in a display interface of the electronic whiteboard based on the whiteboard model data. It should be noted that, the tool software converts the target file into the picture according to the file content, that is, the picture includes the content of the target file, and may be that each page of the file is correspondingly converted into one picture.
When the conference equipment detects that the target file is a file in a picture format, the target file is directly imported into the electronic whiteboard.
In this embodiment, when an instruction for displaying a target file in an electronic whiteboard is detected, whether the target file is a file in a picture format is detected, if not, the target file is converted into a picture and then is imported into the electronic whiteboard, and if so, the target file is directly imported into the electronic whiteboard, so that the electronic whiteboard can compatibly open files in common formats such as PDF, WORLD, JPEG, PNG, and the like.
Further, the step S50 includes:
step S501, the target file is sent to a preset server, so that the preset server correspondingly converts each page of content of the target file into a picture;
the conference device may also send the target file to a preset server. The preset server is internally provided with tool software for converting a file in a document format into a picture, and the preset server correspondingly converts each page of content of the target file into one picture by calling the tool software and returns the picture to the conference equipment. The preset server may be a preset server specially used for converting a file, or may be a server for realizing file sharing among a plurality of conference devices, and an access address of the preset server is preset in the conference device. The preset server can send the target file uploaded by the conference equipment to other equipment which shares the conference file with the conference equipment, so that the other equipment can synchronously display the target file with the conference equipment. It should be noted that, if the preset server implements file sharing between the conference devices, the conference devices may directly upload the target file to be displayed to the preset server, and the preset server performs an operation of determining whether the target file is a picture format file.
Step S502, receiving the picture returned by the preset server, and importing the picture into the electronic whiteboard.
And the conference equipment receives the pictures returned by the preset server and guides the pictures into the electronic whiteboard. In this embodiment, the target file is uploaded to the preset server by the conference device, and the preset server converts the target file into a picture and returns the picture, so that files in common formats such as PDF, WORLD, JPEG, and PNG can be compatibly opened in the electronic whiteboard even when a conversion tool is not installed in the conference device.
Further, in order to reduce the size of the file, the preset server may compress the converted picture, and return the compressed picture to the conference device. In addition, if the conversion is performed locally by the conference equipment, the conference equipment can perform picture compression locally, and the compressed picture is imported into the electronic whiteboard for display.
Further, based on the first or second embodiment, a third embodiment of the conference file processing method of the present invention provides a conference file processing method. In this embodiment, after the step S20, the method further includes:
step S60, adding additional information of the own device to the whiteboard model data, wherein the additional information at least includes size information of the own device;
the conference device may add additional information of the device to the whiteboard model data, where the additional information at least includes size information of the device, and may also include other information, such as a model of the device.
The step S30 includes:
step S301, the whiteboard model data added with the additional information is sorted according to a preset filing sequence and stored as a file in a target format, so that when other equipment opens the file in the target format, the additional information is extracted from the file in the target format, and the file in the target format is adaptively displayed on screens of the other equipment based on the additional information.
And when the conference equipment detects a file storage instruction, sorting the whiteboard model data added with the additional information according to a preset filing sequence, and storing the whiteboard model data as a file in a target format. Files in the target format stored in the conference equipment can be shared in other equipment in a network or USB flash disk copying mode. And when the other equipment opens the file in the target format, calling the electronic whiteboard to open the file in the target format. Specifically, the present apparatus is expressed as an apparatus 1, and the other apparatuses are expressed as apparatuses 2; the device 2 calls an electronic whiteboard, establishes a data model according to a preset data structure, and extracts data of each attribute in a file in a target format according to a preset filing sequence, wherein the data comprises additional information of the device 1; the device 2 acquires the additional information of the device 2, compares the additional information of the device 1 with the additional information of the device 2, and converts the extracted data which needs to be adapted, such as point coordinate information in stroke data, into data of the additional information of the adapting device 2; the device 2 fills the converted data into the data model to obtain whiteboard model data of the device 2, and the device 2 renders an electronic whiteboard display interface in the device 2 based on the whiteboard model data, so that the content of the target format file is displayed on a screen of the device 2.
In this embodiment, the additional information of the device is added to the whiteboard model data, and the whiteboard model data added with the additional information is stored, so that when the stored file is opened by other devices, the content of the file can be adaptively displayed according to the additional information, and the situations that the file content is fuzzy and the file is in disorder when the file is displayed on other devices with different sizes are avoided.
