Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a storage method of note files, and referring to fig. 1, fig. 1 is a schematic flow chart of a first embodiment of the storage method of note files of the invention.
The embodiment of the present invention provides an embodiment of a storage method for a note file, and it should be noted that although a logical order is shown in a flowchart, in some data, the steps shown or described may be completed in a different order.
The storage method of the note file comprises the following steps:
step S10, after detecting the note file to be processed sent by the terminal device, acquiring the note file to be processed, and zooming the preset page in the note file to be processed to obtain the thumbnail file.
Before the file system acquires the note file to be processed, a user edits the file on an editing page according to requirements in a note file APP (terminal software) pre-installed in terminal equipment, and after the file is edited, the edited note file to be processed is sent to the file system through a submitting instruction. The file system acquires the note file to be processed after detecting the note file to be processed sent by the terminal device, analyzes a stroke file in the file editing process through a User Interface (UI) layer logic code, namely, which points belong to a stroke, records information such as stroke type information, line width information and stroke color information, analyzes a coordinate file, namely, a pen point track coordinate, generates an editing file of each page in the note file to be processed according to the analysis stroke file and the coordinate file, acquires a corresponding page in the note file to be processed as an original image file of the note file to be processed, and zooms the original image file according to a preset zooming mode to obtain a corresponding thumbnail image file.
The terminal device includes, but is not limited to, a mobile phone, a tablet computer and an intelligent learning computer. The preset scaling modes include an equal pixel proportion scaling mode, an equal pixel scaling mode and the like. It should be noted that the stroke file and the coordinate file are generated during the file editing process.
Further, the step S10 includes:
step a, after the note file to be processed sent by the terminal equipment is detected, the note file to be processed is obtained, and whether page data of the note file to be processed is larger than or equal to preset page data is detected;
step b, if the page number data is detected to be larger than or equal to the preset page number data, acquiring a preset page corresponding to the preset page number data;
and c, zooming the horizontal pixels and the vertical pixels of the preset page through the same pixels to obtain the thumbnail file.
Specifically, after detecting a to-be-processed note file sent by a terminal device, a file system acquires the to-be-processed note file, acquires page data in the to-be-processed note file, then detects whether the page data in the to-be-processed note file is greater than or equal to preset page data, if it is detected that the page data is greater than or equal to the preset page data, the file system acquires a preset page corresponding to the preset page data as an original image file, and if it is detected that the page data is less than the preset page data, the file system acquires a preset page corresponding to page data 1 in the to-be-processed file as the original image file. After the file system acquires the preset page, the preset zooming requirement is acquired, and the horizontal pixels and the vertical pixels of the preset page are zoomed in a zooming mode of equal pixel scale zooming according to the preset zooming requirement, so that the corresponding thumbnail file is acquired. The preset zooming requirement is set by the user according to the requirement, and the embodiment is not limited.
In this embodiment, for example, the preset page code data is 5, the preset zoom requirement is reduced to one fourth of the original size, and the file system detects that the page code data of the to-be-processed note file is 8, then a page corresponding to the page code data of 5 in the to-be-processed note file is acquired as a preset page, and then both the horizontal pixels and the vertical pixels of the preset page are reduced to half of the original size, so as to obtain the thumbnail file. Further, the preset page code data is 5, if the file system detects that the page code data of the to-be-processed note file is 4, the page corresponding to the page code data 1 in the to-be-processed file is taken as the preset page, and then the horizontal pixels and the vertical pixels of the preset page are reduced to half of the original value, so that the thumbnail file is obtained.
Step S20, acquiring an edit file, and compressing the edit file, the note file to be processed and the thumbnail file respectively to obtain a first compressed file corresponding to the edit file, a second compressed file corresponding to the note file to be processed and a third compressed file corresponding to the thumbnail file.
The file system acquires the editing file stored in the memory, and then compresses the obtained editing file, the note file to be processed and the thumbnail file respectively through a preset compression format to obtain a first compression file corresponding to the editing file, a second compression file corresponding to the note file to be processed and a third compression file corresponding to the thumbnail file. The preset compression format includes, but is not limited to, LZO (data compression algorithm) compression format, ZIP (file format for data compression and document storage) compression format, and RAR (file format for data compression and archive packaging) compression format.
Further, the step S20 includes:
step d, acquiring the editing file, wherein the editing file comprises a stroke file and a coordinate file;
and e, compressing the editing file, the note file to be processed and the thumbnail file respectively through a preset compression format to correspondingly obtain the first compression file, the second compression file and the third compression file.
Specifically, the file system acquires an editing file stored in the memory, wherein the editing file comprises a stroke file and a coordinate file, and the editing file, a note file to be processed and a thumbnail file are respectively compressed through an LZO compression format, so that a first compression file is obtained correspondingly as the editing file, an LZO, a second compression file is obtained correspondingly as the thumbnail file, and the LZO and a third compression file are obtained correspondingly as the thumbnail file.
Further, when the editing page is subjected to file editing, the file system records information such as type information, color information and line width information of an editing tool on the editing page, and information such as position information, change sequence, end position and start position of all coordinates of the editing tool in the sliding process, and then determines the note file to be processed according to the sliding track of the editing tool. The information such as type information, color information, line width information and the like of the editing tool is a stroke file of the editing file, and the information such as position information, change sequence, end position, starting position and the like of all coordinates of the editing tool in the sliding process is a coordinate file of the editing file.
In this embodiment, for example, the stroke file is an editing tool of which the type is pen, the color is black, the line width is regular font 4, the editing tool is in the sliding process, the file system records that all coordinates and change sequences of the editing tool are (4, 12), (0, 7), (0, 4), (8, 4), (2, 10) and (2, 0), the sequence of the start coordinate positions is (4, 12), (0, 4) and (2, 10), the end coordinate positions are (0, 7), (8, 4) and (2, 0), the file system determines that the character "thousand" is included according to the sliding track of the editing tool, and determines the page corresponding to the character "thousand" as the note file to be processed, the editing file is an editing tool of which the type is pen, the color is black, the line width is regular font 4, and all coordinates and change sequences of the editing tool are (4, 12), (0, 7), (0, 4), (8, 4), (2, 10) and (2, 0), the order of the start coordinate positions is (4, 12), (0, 4) and (2, 10), and the end coordinate positions are (0, 7), (8, 4) and (2, 0).
Step S30, the first compressed file, the second compressed file, and the third compressed file are packaged to obtain a to-be-stored note file, and the note file in the FLASH memory FLASH is updated based on the to-be-stored note file.
After the file system obtains the first compressed file, the second compressed file and the third compressed file, the first compressed file, the second compressed file and the third compressed file are packaged in a preset packaging mode to obtain a note file to be stored, and then the note file to be stored replaces the original note file stored in the FLASH.
Further, the step S30 includes:
step f, acquiring first position information corresponding to the first compressed file, second position information corresponding to the second compressed file and third position information corresponding to the third compressed file, and constructing a packet header file according to the first position information, the second position information and the third position information;
and g, packaging the first compressed file, the second compressed file, the third compressed file and the packet header file to obtain the note file to be stored.
Specifically, the file system acquires first position information corresponding to a first compressed file, second position information corresponding to a second compressed file and third position information corresponding to a third compressed file from a database, combines the first position information, the second position information and the third position information, constructs a packet header file containing the first position information, the second position information and the third position information, and splices the packet header file with the first compressed file, the second compressed file and the third compressed file as a file identifier to obtain a note file to be stored.
It should be noted that, the header file records relative position information of the first compressed file, the second compressed file, and the third compressed file in the header file, and the corresponding compressed file can be acquired through the relative position information.
In this embodiment, for example, the file system obtains that the first position information is offset + file _ size, the second position information is offset + offset + file _ size, and the third position information is offset + offset + file _ size in the database, then combines offset + file _ size, offset + offset + file _ size, and offset + offset + offset + file _ size to construct a header file, and then splices the header file with the first compressed file, the second compressed file, and the third compressed file to obtain the to-be-stored note file.
Further, referring to fig. 2, fig. 2 is an analysis diagram of the storage method of the note file of the present invention, the file system performs LZO format compression on the thumbnail file, the file to be processed (large image file), the stroke file, and the coordinate file, and then performs packing and splicing on the compressed thumbnail file, LZO, the file to be processed, LZO, the stroke file, LZO, and the coordinate file, LZO, and the Header file (Header) to obtain a note file to be stored (synthetic note file), and finally stores the note file to be stored in FLASH. The header file records the relative position information of each compressed file in the whole note file to be stored.
According to the embodiment, the note file to be stored is obtained by obtaining the note file to be processed, zooming the preset page in the note file to be processed to obtain the thumbnail file, then compressing the edit file, the note file to be processed and the thumbnail file to obtain the first compressed file, the second compressed file and the third compressed file correspondingly, finally packing the first compressed file, the second compressed file and the third compressed file to obtain the note file to be stored, and storing the note file to be stored to FLASH. Therefore, in the process of obtaining the note files to be stored, the edit files, the note files to be processed and the thumbnail files need to be compressed, so that the size of the memory occupied by the note files is reduced, the note files can be stored quickly, and the storage efficiency of the note files is improved. Moreover, a plurality of files of the editing file, the note file to be processed and the thumbnail file are packaged into one file to obtain the note file to be stored, so that different files can be obtained by operating the FATFS file system FAT table once, the erasing frequency of FLASH is reduced, the abrasion of FLASH is reduced, and the storage efficiency of the note file is improved.
Further, a second embodiment of the storage method of the note file of the present invention is provided.
The second embodiment of the note file storage method is different from the first embodiment of the note file storage method in that the note file storage method further includes:
h, detecting a file type corresponding to the file reading request after detecting the file reading request sent by the terminal equipment, and acquiring a corresponding compressed file in the FLASH according to the file type;
and step i, decompressing the compressed file to obtain a corresponding decompressed file, and returning the decompressed file to the terminal equipment.
Specifically, after detecting a file reading request sent by a terminal device, a file system detects a file type corresponding to the file reading request, acquires position information corresponding to the file type in a header file, then acquires a compressed file corresponding to the file type in a FLASH according to the acquired position information, decompresses the acquired compressed file in a corresponding decompression mode to acquire a decompressed file corresponding to the file type, and sends the decompressed file to the terminal device, so that a user checks or edits the decompressed file through the terminal device.
When a file is decompressed, the decompression method of the decompressed file and the compression method are consistent, for example, the compression format is LZO, and the corresponding decompression format when the file is decompressed is LZO. The compression format is RAR, and the decompression format corresponding to the decompression is RAR.
Further, the step h includes:
step j, after detecting a file reading request sent by the terminal equipment, detecting a file type corresponding to the file reading request;
and k, if the file type is detected to be the view of the original file, determining a second compressed file corresponding to the note file to be stored in the note file of the FLASH through the packet header file as the compressed file.
Specifically, after detecting a file reading request sent by the terminal device, the file system detects a file type corresponding to the file reading request, and if the file type is detected to be an original image file, the file system acquires the position information of the file to be processed in the header file, and then acquires a second compressed file corresponding to the note file to be stored in the FLASH as a compressed file, namely, a compressed file of the file to be processed according to the position information. Further, if the file type is detected to be the view thumbnail file, the file system acquires the position information of the thumbnail file in the header file, and then acquires a third compressed file corresponding to the note file to be stored in the FLASH as a compressed file, namely the compressed file of the thumbnail file, according to the position information.
In this embodiment, after detecting a file reading request sent by a terminal device, a file type corresponding to the file reading request is detected, and a corresponding compressed file is obtained in a FLASH according to the file type, and then the compressed file is decompressed to obtain a corresponding decompressed file, and the decompressed file is returned to the terminal device. Therefore, in the embodiment, the corresponding position information is obtained in the header file according to the file type, the compressed file corresponding to the note file to be stored is obtained in the FLASH according to the position information, the compressed file is decompressed finally, and the decompressed file is returned to the terminal device, so that the corresponding compressed file can be obtained by operating the FLASH once, the erasing frequency of the FLASH is reduced, the abrasion of the FLASH is reduced, and the utilization rate of the FLASH is improved.
Further, a third embodiment of the storage method of the note file of the present invention is provided.
The third embodiment of the note file storage method is different from the first embodiment or/and the second embodiment of the note file storage method in that the note file storage method further comprises:
step l, if an editing instruction sent by the terminal equipment is detected, acquiring a first compressed file corresponding to the editing file in a note file of the FLASH through a packet header file, and decompressing the first compressed file to obtain the stroke file and the coordinate file;
step m, returning the stroke file and the coordinate file to the terminal equipment so that a user can edit the note file to be processed through the stroke file and the coordinate file and feed back the edited note file to be processed;
and n, compressing the edited note file to be processed, and updating the note file in the FLASH memory FLASH.
Specifically, after the file system acquires the second compressed file corresponding to the file to be processed, if an editing instruction sent by the terminal device is detected, the position information of the editing file in the header file is acquired, the first compressed file corresponding to the editing file is acquired in the note file of the FLASH through the position information, then the first compressed file is decompressed to obtain the corresponding stroke file and coordinate file, then the stroke file and coordinate file are returned to the terminal device, after the user receives the stroke file and coordinate file, the note file to be processed is edited in the terminal device through the stroke file and coordinate file to obtain the updated note file to be processed, and the updated note file to be processed is fed back to the file system through the terminal device, after the file system receives the updated note file to be processed, the updated note file to be processed is compressed according to the steps of the first embodiment, and then replace the original note file in FLASH.
If an editing instruction sent by the terminal device is detected, a first compressed file corresponding to the editing file is obtained in the note file of the FLASH memory through the header file, the first compressed file is decompressed to obtain a stroke file and a coordinate file, the stroke file and the coordinate file are returned to the terminal device, so that a user can edit the note file to be processed through the stroke file and the coordinate file, feed back the edited note file to be processed, compress the edited note file to be processed, and update the note file in the FLASH memory. Therefore, when editing a file, the embodiment only needs to acquire the position information through the same message file, then acquires the editing file through the position information to edit the file, and does not need to acquire the editing file in another file, so that the use of the FAT table in the file system is reduced, the erasing frequency of the FLASH is reduced, the abrasion of the FLASH is reduced, and the utilization rate of the FLASH is improved.
