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.
Fig. 1 is a schematic diagram of an electronic device 1 according to a preferred embodiment of the invention.
In the embodiment, the electronic device 1 may be a server, a smart phone, a tablet computer, a personal computer, a portable computer, and other electronic devices with an arithmetic function.
The electronic device 1 includes: memory 11, processor 12, display 13, network interface 14, and communication bus 15. The network interface 14 may optionally include a standard wired interface, a wireless interface (e.g., WI-FI interface), among others. The communication bus 15 is used to realize connection communication between these components.
The memory 11 includes at least one type of readable storage medium. The at least one type of readable storage medium may be a non-volatile storage medium such as a flash memory, a hard disk, a multimedia card, a card-type memory, and the like. In some embodiments, the memory 11 may be an internal storage unit of the electronic device 1, such as a hard disk of the electronic device 1. In other embodiments, the memory 11 may also be an external storage unit of the electronic device 1, such as a plug-in hard disk, a Smart Media Card (SMC), a Secure Digital (SD) Card, a Flash memory Card (Flash Card), and the like, which are provided on the electronic device 1.
In the present embodiment, the memory 11 can be used not only for storing the application software installed in the electronic device 1 and various types of data, such as the compression tool calling program 10, various types of compression tools 16, and records of compression time and compression rate of various types and sizes of files in each compression tool, but also for temporarily storing data that has been output or will be output.
The processor 12 may be a Central Processing Unit (CPU), microprocessor or other data Processing chip in some embodiments, and is used for executing program codes stored in the memory 11 or Processing data, such as computer program codes for executing the compression tool calling program 10.
The display 13 may be referred to as a display screen or display unit. In some embodiments, the display 13 may be an LED display, a liquid crystal display, a touch-sensitive liquid crystal display, an Organic Light-Emitting Diode (OLED) touch screen, or the like. The display 13 is used for displaying information processed in the electronic device 1 and for displaying a visual work interface, such as a compression mode selection page.
Preferably, the electronic device 1 may further comprise a user interface, which may comprise an input unit such as a Keyboard (Keyboard), a voice output device such as a sound box, a headset, etc., and optionally a standard wired interface, a wireless interface.
In the embodiment of the apparatus shown in fig. 1, the memory 11 as a computer storage medium stores the program code of the compression tool calling program 10, and when the processor 12 executes the program code of the compression tool calling program 10, the following steps are implemented:
and (3) analyzing: responding to the operation of starting the compressed file by the user each time, analyzing the type and the size of the file to be compressed, and recording the compression mode and the compression tool selected by the user;
a recording step: after the compression is finished, recording the compression rate and the compression time of the compression tool aiming at the files of the type and the size under the compression mode;
a calculation step: calculating a recommended value of each compression tool about the compression rate or a recommended value of compression time for each type of file under each compression mode according to a preset recommended value calculation formula every other preset period;
a receiving step: receiving a request of compressing a file by a user and a compression mode selected by the user;
calling: and under the compression mode, selecting a compression tool corresponding to the maximum recommended value of the compression rate or the maximum recommended value of the compression time, and automatically calling the selected compression tool to perform compression operation on the file.
In this embodiment, the compression tool calling program 10 responds to the operation of starting the compression file by the user each time, analyzes the type and size of the file to be compressed, and records the compression mode and the compression tool selected by the user. For example, when a user compresses a picture file, a compression tool calling program automatically analyzes the type and the occupied space size of the picture file to be compressed, and records a compression mode and a compression tool selected by the user. Wherein the file types include: multimedia files (e.g., audio files, video files, image files, etc.), document class files (e.g., doc files, txt files, xls files, etc.), and executable files (e.g., exe file installation packages, etc.). The compression rate and compression time for compressing files by different compression tools are different for different types and sizes of files. For example, the compression rates of fastlz and lz4 for 2M txt files are 14% and 18%, respectively, and the compression times are 4s and 6s, respectively. The compression mode includes an extreme compression mode and a very high compression mode. The extreme compression mode mainly focuses on the compression rate of the file, and the extreme compression mode mainly focuses on the compression time of the file.
After the compression is completed, the compression tool calling program 10 records the compression rate and the compression time of the compression tool for the file of the type and size under the compression mode. For example, the user selects the limit compression mode, and the called compression tool is WinRAR, after the compression is completed, the compression mode, the compression tool, the file type, the file size, the compression rate, and the compression time are recorded as follows: limit compression mode-WinRAR-picture file-4M-28% -10 s. Wherein the compression tool comprises: one or more compression tools such as fastlz, lz4, snappy, deflate, WinRAR, WinZip, zlib and the like.
The compression tool calling program 10 calculates a recommended value of each compression tool with respect to the compression rate or a recommended value of the compression time for each type of file in each compression mode according to a preset recommended value calculation formula every preset period. For example, in the last night of each month, the compression tool calling program automatically calculates the recommended value of each file in each compression tool according to the compression rate and the compression time of each type of file in each compression tool recorded in the month by using a preset recommended value calculation formula.
Wherein the preset recommended value calculation formula comprises:
under the limit compression mode, the recommended value calculation formula is as follows:
wherein Y is 1 Representing a compression rate recommendation, X, for a certain type of file in a certain compression tool i The compression rate of the type file in the preset period under the compression tool is represented, and n is a positive integer and represents the number of the type files compressed by the compression tool in the preset period. For example, in a preset period, if the compression rate of the winter rar for doc files is 30% and 28%, the recommended value calculation formula is used:
the compression rate recommendation value of doc file in WinRAR is calculated to be 71.
In the extreme speed compression mode, the recommended value calculation formula is as follows:
wherein Y2 representsCompression time recommendation value, M, for a certain type of file in a certain compression tool ij /N ij Representing the ratio of the compression time to the file size of the type file under all compression tools in a preset period, M i /N i Representing the ratio of the compression time of the type file under a certain compression tool to the file size in a preset period, m is a positive integer representing the number of compression tool pressures, and n is a positive integer representing the number of the type files compressed by the compression tool in the preset period. Assuming that only two compression tools of WinRAR and WinZip are available in the compression tools, and the compression time is 8s and 4s respectively for a jpg picture file of 4M, a recommended value calculation formula is utilized:
the compression time recommendation values of the jpg picture file in WinRAR and WinZip are respectively 10 and 40.
When a user needs to compress the multimedia file, selecting a proper compression mode on the compression mode selection page. The compression tool calling program 10 receives a request for compressing a file from a user and a compression mode selected by the user. For example, a 4M jpg picture file and a user selected extreme speed compression mode are received.
The compression tool calling program 10 automatically calls the compression tool with the maximum compression rate recommendation value or the maximum compression time recommendation value to execute the compression operation on the file to be compressed according to the compression mode selected by the user. For example, in the extreme speed compression mode, assuming that the file to be compressed is a 4M jpg picture file and only two compression tools of WinRAR and WinZip are available among the compression tools, and the compression time recommendation values of the 4M jpg picture file in WinRAR and WinZip are 10 and 40 respectively, WinZip is called to compress the 4M jpg picture file.
In another embodiment, a recommended compression rate value or a recommended compression time value of the file to be compressed in each compression tool in the selected compression mode may be displayed to the user, and the user selects an appropriate compression tool to perform the compression operation according to the service scenario. For example, in the extreme speed compression mode, the compression time recommendation values of WinRAR and WinZip of the jpg picture file displayed in 4M are 10 and 40 respectively, and even if the compression time of WinRAR is long, if the distortion of the compression of the WinRAR is small, the user can still select the WinRAR to compress the file.
The compression tool calling method provided in the above embodiment queries the compression rate recommended value or the compression time recommended value of the file to be compressed in each compression tool according to the compression mode selected by the user, and automatically calls the optimal compression tool to perform compression processing on the file, thereby reducing manual compression operation of the staff and improving the service processing efficiency.
Fig. 2 is a block diagram of the compression tool calling program 10 of fig. 1 according to an embodiment. The modules referred to herein are referred to as a series of computer program instruction segments capable of performing specified functions.
In this embodiment, the compression tool calling program 10 includes: the parsing module 110, the recording module 120, the calculating module 130, the receiving module 140, and the invoking module 150, the functions or operation steps implemented by the modules 110 and 150 are similar to those described above, and are not detailed here, for example, where:
the analysis module 110 is configured to respond to an operation of starting the compressed file by a user each time, analyze the type and size of the file to be compressed, and record a compression mode and a compression tool selected by the user;
a recording module 120, configured to record, after the compression is completed, a compression rate and a compression time of the compression tool for the file of the type and size in the compression mode;
the calculation module 130 is configured to calculate, every preset period, a recommended value of each compression tool with respect to a compression rate or a recommended value of compression time for each type of file in each compression mode according to a preset recommended value calculation formula;
a receiving module 140, configured to receive a request for compressing a file from a user and a compression mode selected by the user;
the invoking module 150 is configured to select a compression tool corresponding to the maximum recommended value of the compression rate or the maximum recommended value of the compression time in the compression mode, and automatically invoke the selected compression tool to perform a compression operation on the file.
Fig. 3 is a flow chart of a first embodiment of the compression tool calling method according to the present invention.
In this embodiment, the implementation of the compression tool calling method when the processor 12 executes the computer program of the compression tool calling program 10 stored in the memory 11 includes: step S10-step S50:
step S10, as shown in fig. 7, is an application environment diagram of the compression tool calling method of the present invention, where the compression tool calling program 10 responds to the operation of the user to start compressing the file each time, analyzes the type and size of the file to be compressed, and records the compression mode and the compression tool selected by the user. Wherein the compression tools are stored in a compression tool library 16. For example, when a user compresses a picture file, a compression tool calling program automatically analyzes the type and the occupied space size of the picture file to be compressed, and records a compression mode and a compression tool selected by the user. Wherein the file types include: multimedia files (e.g., audio files, video files, image files, etc.), document class files (e.g., doc files, txt files, xls files, etc.), and executable files (e.g., exe file installation packages, etc.). The compression rate and compression time for compressing files by different compression tools are different for different types and sizes of files. For example, the compression rates of fastlz and lz4 for 2M txt files are 14% and 18%, respectively, and the compression times are 4s and 6s, respectively. The compression mode includes an extreme compression mode and a very high compression mode. The extreme compression mode mainly focuses on the compression rate of the file, and the extreme compression mode mainly focuses on the compression time of the file.
In step S20, after the compression is completed, the compression tool calling program 10 records the compression rate and the compression time of the compression tool for the file of the type and size under the compression mode. For example, the user selects the limit compression mode, and the called compression tool is WinRAR, after the compression is completed, the compression mode, the compression tool, the file type, the file size, the compression rate, and the compression time are recorded as follows: limit compression mode-WinRAR-picture file-4M-28% -10 s. Wherein the compression tool comprises: one or more compression tools such as fastlz, lz4, snappy, deflate, WinRAR, WinZip, zlib and the like.
In step S30, the compression tool calling program 10 calculates, for each compression mode, a recommended value of the compression rate or a recommended value of the compression time for each type of file for each compression tool according to a preset recommended value calculation formula every preset period. For example, in the last night of each month, the compression tool calling program automatically calculates the recommended value of each file in each compression tool according to the compression rate and the compression time of each type of file in each compression tool recorded in the month by using a preset recommended value calculation formula.
Wherein the preset recommended value calculation formula comprises:
under the limit compression mode, the recommended value calculation formula is as follows:
wherein Y is 1 Representing a compression rate recommendation, X, for a certain type of file in a certain compression tool i The compression rate of the type file in the preset period under the compression tool is represented, and n is a positive integer and represents the number of the type files compressed by the compression tool in the preset period. For example, in a preset period, if the compression rate of the winter rar for doc files is 30% and 28%, the recommended value calculation formula is used:
the compression rate recommendation value of doc file in WinRAR is calculated to be 71.
In the extreme speed compression mode, the recommended value calculation formula is as follows:
where Y2 represents the compression time recommendation for a type of file in a compression tool, M ij /N ij Representing the ratio of the compression time to the file size of the type file under all compression tools in a preset period, M i /N i Representing the ratio of the compression time of the type file under a certain compression tool to the file size in a preset period, m is a positive integer representing the number of compression tools, n isAnd the positive integer represents the number of the type files compressed by the compression tool in a preset period. Assuming that only two compression tools of WinRAR and WinZip are available in the compression tools, and the compression time is 8s and 4s respectively for a jpg picture file of 4M, a recommended value calculation formula is utilized:
the compression time recommendation values of the jpg picture file in WinRAR and WinZip are respectively 10 and 40.
In step S50, the compression tool calling program 10 automatically calls the compression tool with the maximum recommended compression ratio value or the maximum recommended compression time value from the compression tool set 16 to perform compression on the file to be compressed according to the compression mode selected by the user. For example, in the extreme speed compression mode, assuming that the file to be compressed is a 4M jpg picture file and only two compression tools of WinRAR and WinZip are available among the compression tools, and the compression time recommendation values of the 4M jpg picture file in WinRAR and WinZip are 10 and 40 respectively, WinZip is called to compress the 4M jpg picture file.
In another embodiment, as shown in FIG. 4, it is a flow chart of the second embodiment of the compression tool calling method of the present invention. Step S50 may also be displaying, to the user, a recommended compression rate value or a recommended compression time value of the file to be compressed in each compression tool in the selected compression mode, and the user selects a suitable compression tool to perform the compression operation according to the service scenario. For example, in the extreme speed compression mode, the compression time recommendation values of WinRAR and WinZip of the jpg picture file displayed in 4M are 10 and 40 respectively, and even if the compression time of WinRAR is long, if the distortion of the compression of the WinRAR is small, the user can still select the WinRAR to compress the file.
The compression tool calling method provided by the embodiment provides the compression mode for the user, and calls the compression tool most suitable for the service scene to perform compression operation on the file according to the compression rate recommended value or the compression time recommended value of the file to be compressed in each compression tool under the compression mode selected by the user, so that the file storage space is saved, and the compression performance is improved.
Fig. 5 is a flowchart of a third embodiment of the compression tool invoking method according to the present invention.
In this embodiment, the compression tool calling method includes: step S10-step S70. The contents of steps S10-S40 are substantially the same as those in the first embodiment, and are not described herein again.
In the compression mode selected by the user, the compression tool calling program 10 generates a numerical range in which a random number is generated according to the compression rate recommendation value or the compression time recommendation value of each compression tool for the type of file at step S50. For example, in the extreme compression mode, the recommended compression time values of the 2Mtxt file in the fastlz, lz4 and snappy compression tools are 10, 20 and 60 respectively, the minimum value of the random number generated by the compression tool calling program 10 is 0, the maximum value is 90, and a random number is generated, assuming that the random number is 30.
In step S60, the compression tool calling program 10 calculates a difference between the generated random number and the recommended value for each compression tool based on the random number. For example, the random number is 30, and the difference value between the random number and the compression time recommendation value (10, 20, 60) of the 2Mtxt file in three compression tools of fastlz, lz4 and snappy is 20, 10 and 30 respectively.
In step S70, the compression tool calling program 10 selects the compression tool corresponding to the minimum difference value from the compression tool set 16, and automatically calls the compression tool to perform a compression operation on the file. The automatic mode is suitable for a large number of file compression applications. For example, according to the random number 30, the difference values with the compression time recommendation values in three compression tools of fastlz, lz4 and snappy are respectively 20, 10 and 30, and the compression tool (lz4) with the minimum difference value is automatically selected to compress the file.
In another embodiment, as shown in fig. 6, it is a flow chart of the fourth embodiment of the compression tool calling method of the present invention. Step S70 may also be to assign different recommendation levels to each compression tool according to the order of the difference from small to large, and to present the user with a reference selection. The recommended mode is applicable to a small number of file compression requests. For example, by assigning the highest recommendation level to lz4, the next highest recommendation level to fastlz, and the lowest recommendation level to snappy, based on the difference values of 20, 10, and 30, the user may select a compression tool from the set of compression tools 16 for file compression based on the recommendation levels.
Compared with the first embodiment, the compression tool calling method provided by the embodiment generates a numerical range according to the recommended value of the file to be compressed in each compression tool, generates a random number in the range, and then adopts a mode of combining the recommended value with the random number, so that the compression tool with a smaller recommended value is also called to execute compression operation with a certain probability, and the burden of the compression tool with a larger recommended value is reduced.
Furthermore, an embodiment of the present invention further provides a computer-readable storage medium, where the computer-readable storage medium includes a compression tool calling program 10, and when executed by a processor, the compression tool calling program 10 implements the following operations:
and (3) analyzing: responding to the operation of starting the compressed file by the user each time, analyzing the type and the size of the file to be compressed, and recording the compression mode and the compression tool selected by the user;
a recording step: after the compression is finished, recording the compression rate and the compression time of the compression tool aiming at the files of the type and the size under the compression mode;

calling: and under the compression mode, selecting a compression tool corresponding to the maximum recommended value of the compression rate or the maximum recommended value of the compression time, and automatically calling the selected compression tool to perform compression operation on the file.
Optionally, the calling step may be replaced by the displaying step: and under the mode selected by the user, showing the compression rate recommendation value or the compression time recommendation value of each compression tool to the user for the user to perform the compression operation by referring to the selected compression tool.
