The embodiment of the application provides a data generation method, which can be applied to the electronic equipment. In the following, the data generating apparatus in which the data generating method is applied to the electronic device is taken as an example for explanation, and in the practical application process, the data generating method may be applied to other similar devices including the data generating apparatus. As shown in fig. 3, the method may include S301-S302:
s301, the data generation device acquires the calling parameter of the current page displayed by the application program.
The calling parameter of the current page is used for indicating the operation object in the current page and the position of the operation object in the current page. The current page includes a current image frame that the application displays by invoking the parameter in response to a user action.
As a possible implementation manner, the data generating device may generate an interception instruction, and insert the interception instruction into an interface function of an Application Program Interface (API) for displaying a current page, so that when the application program displays the current page by calling the target API, a calling parameter of the application program displaying the current page is obtained.
For example, in the case where the application program is applied to the graphical interface service program xwindows, the data generation apparatus may directly insert the interception instruction into the interface function of the target API after generating the interception instruction. In this way, when the application program displays the current page in the calling target API, the interception instruction may directly send the calling parameters of the current page, which are required by the application program to call the target API, to the data generation apparatus.
It should be noted that the call parameters of the current page may include: the window handle, the operation object and the current object parameter of the operation object on the current page.
The operation object may be an input text object and a drawing object of the application program in the current page, and the object parameter may be a start coordinate of the text object output by the current page, font information (including a length, a width, a height, a gap between characters, and the like of each character), a type (such as a line, a point, a rectangle, an ellipse, and the like) and a size of the drawing object.
Illustratively, the interface function of the target API may specifically be: gdifunc () { Statement1 … }. After the interception instruction is added, the following steps can be performed: gdifunc () { Jmp Savepara state 1 … } Savepara; jmp status.
The specific implementation manner of this step may refer to the subsequent description of the embodiment of the present application, and is not described herein again.
S302, the data generation device generates difference data of the current page and the previous page based on the previous page of the current page and the acquired calling parameters of the current page.
Wherein the difference data is used for encoding or decoding in image transmission. The previous page is the image frame displayed immediately before the current page.
As a possible implementation manner, the data generation apparatus obtains a previous page of the current page, and determines the history object parameter of the operation object in the previous page based on the window handle in the call parameter of the current page.
Further, the data generating device determines the difference between the historical object parameter and the current object parameter as the difference data of the current page and the previous page.
The specific implementation manner of this step may refer to the subsequent description of the embodiment of the present application, and is not described herein again.
It can be understood that the difference data determined by the data generating device is data of a difference area between the current page and the previous page, which includes object parameters such as a position and a size of the operation object on the current page and object parameters such as a position and a size of the operation object on the previous page.
In some subsequent embodiments, the data generating means transmits the difference data to the data receiving device after determining the difference data.
Accordingly, after receiving the difference data, the data receiving device may generate a current page from the previous page and the received difference data, and display the current page.
In one design, in order to obtain the call parameter of the current page, as shown in fig. 4, S301 provided in this embodiment of the present application specifically includes the following S3011 to S3012:
s3011, the data generation device generates an intercept instruction.
The interception instruction is used for acquiring the input operation of the application program.
As a possible implementation manner, the data generation apparatus may generate the interception instruction based on a preset code.
Illustratively, the code corresponding to the above interception instruction may be { Jmp savepara Statement1 … }.
S3012, the data generation device obtains the call parameter of the current page from the target application program interface API of the application program based on the generated interception instruction.
Wherein the target API is used for displaying the current page.
As a possible implementation manner, the data generation apparatus inserts the generated result instruction into an interface function of the target API to obtain a call parameter of the current page.
The application program can also be applied to a Windows operating system, but the Windows operating system cannot directly insert the interception instruction into the interface function of the target API. Therefore, in order to insert an intercept instruction into an interface function of a target API in a Windows operating system, as shown in fig. 5, in a design, in the data generation method provided in this embodiment of the present application, the above S3012 specifically includes the following S401 to S402:
s401, under the condition that the application program is applied to the Windows operating system, based on a preset first instruction, the data generation device determines a target address where a target process is located.
The target process is a process occupied by the target API in the application program.
As a possible implementation manner, the data generating apparatus may first determine a target process occupied by the target API, and then enter a target address of the target process in the application program through a preset first instruction.
It should be noted that the target address is a space in the memory for executing the target process in the application program.
For example, the first instruction may be a SetWindowsHook function, and this function may insert any instruction or program into a space or address where any process is located. The first instruction may be set in the data generating device or the electronic device in advance by an operation and maintenance person.
S402, inserting the interception instruction into the instruction stored in the target address by the data generation device based on a preset second instruction to obtain the calling parameter of the current page.
As a possible implementation manner, the data generation apparatus may change an instruction or a program stored in the target address by a preset second instruction, for example, an interception instruction may be inserted into the instruction or the program stored in the target address, so as to acquire the call parameter of the current page.
Illustratively, the second instruction may be a WriteProcessMemory function, which may change the contents of any instruction or program.
For example, the data generation device runs the WriteProcessMemory function in the target process through the setwindowschook function, the data generation device modifies the API of the target process by running the WriteProcessMemory function in the target process, for example, an intercept instruction is inserted into the API, and the data generation device obtains the call parameter of the current page according to the intercept instruction.
In one design, the call parameters of the current page provided in the embodiment of the present application include a window handle, the operation object, and a current object parameter of the operation object in the current page. And the current object parameter is the object parameter of the operation object in the current page. In order to generate difference data between the current page and the previous page based on the previous page of the current page and the obtained calling parameter of the current page, as shown in fig. 6, S302 provided in this embodiment of the application specifically includes the following S3021 to S3022.
S3021, the data generating apparatus determines the history object parameter of the previous page of the operation object based on the window handle.
As a possible implementation manner, the data generation apparatus acquires the previous page, and determines the history object parameter of the operation object in the previous page according to the acquired window handle.
It should be noted that the history object parameters may include object parameters such as a cursor position, a size, and a line thickness of the operation object on the previous page.
S3022, the data generating means generates difference data based on the determined history object parameter and the current object parameter.
Wherein the difference data comprises difference information between the historical object parameters and the current object parameters.
As one possible implementation, the data generation means determines difference information between the current object parameter and the historical object parameter, and determines the determined difference information as difference data. For example, the difference information may include a difference between the starting coordinates of the text object in the current page and the previous page, the font information, and a difference between the type or size of the drawing object in the previous page and the current page.
According to the data generation method, the current graphic change area is accurately calculated by intercepting the API call of the graphic interface output and calling the parameters, the image and the font context, only the change area is directionally compressed, compared with the prior art, the change area is found out and directionally compressed without carrying out global index on a screen by utilizing macro block scanning and macro block searching, time consumed for calculating different video image frame differences is reduced, the operation efficiency of a video compression algorithm is improved, and user experience is optimized.
