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 an edited file stored in the memory, and then compresses the obtained edited 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 edited file, a second compression file corresponding to the note file to be processed and a third compression file corresponding to the thumbnail file, wherein the preset compression format comprises but is not limited to L ZO (data compression algorithm) compression format, ZIP (file format for data compression and document storage) compression format and RAR (file format for data compression and filing 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 editing files stored in the memory, wherein the editing files comprise stroke files and coordinate files, the editing files, note files to be processed and thumbnail files are respectively compressed through a L ZO compression format, and accordingly a first compression file, which is an editing file, L ZO, a second compression file, which is a file to be processed, L ZO and a third compression file, which is a thumbnail file, L ZO are obtained.
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 F L ASH 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 is replaced with the original note file stored in the F L ASH.
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 a storage method of note files according to the present invention, a file system compresses a thumbnail file, a file to be processed (a large image file), a stroke file, and a coordinate file in L ZO format, then packs and splices the compressed thumbnail file, L ZO, the file to be processed, L ZO, the stroke file, L ZO, and the coordinate file, L ZO, with a Header file (Header), to obtain a note file to be stored (a composite note file), and finally stores the note file to be stored in F L ASH, wherein the Header file records relative position information of each compressed file in the whole note file to be stored.
According to the method, the note file to be processed is obtained, the preset page in the note file to be processed is scaled to obtain the thumbnail file, the edit file, the note file to be processed and the thumbnail file are compressed to obtain the first compressed file, the second compressed file and the third compressed file correspondingly, finally the first compressed file, the second compressed file and the third compressed file are packaged to obtain the note file to be stored, and the note file to be stored is stored in the F L ASH.

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, obtains location information corresponding to the file type in a header file, then obtains a compressed file corresponding to the file type in F L ASH according to the obtained location information, decompresses the obtained compressed file in a corresponding decompression manner to obtain a decompressed file corresponding to the file type, sends the decompressed file to the terminal device, and a user views or edits the decompressed file through the terminal device.
When a file is decompressed, the decompression method and the compression method of the decompressed file are consistent, for example, the compression format is L ZO, the decompression format corresponding to the decompression is L ZO. compression format RAR, and the decompression format corresponding to the decompression is RAR.
Further, the step h includes:
