Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments, but not all embodiments, of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The method for scaling the picture synchronization across terminals according to the present invention will be explained and illustrated in detail by specific embodiments.
Fig. 1 is a schematic flowchart of a cross-terminal image synchronous zooming method according to an embodiment of the present invention; as shown in fig. 1, the method includes:
step 101: acquiring zooming state data of a first terminal after zooming operation is performed on a target picture; the zooming state data comprises zooming times after zooming operation is carried out on the target picture and relative coordinates of the center point of the target picture on the screen after the zooming operation is carried out.
Step 102: and sending a picture synchronous zooming request containing zooming state data to the second terminal so that the second terminal can synchronously zoom the local target picture according to the zooming state data, thereby realizing the synchronous zooming of the pictures of the first terminal and the second terminal.
In this embodiment, it should be noted that the present embodiment is applied to synchronous zooming of pictures between a first terminal and a second terminal, and target pictures to be synchronously zoomed are stored in both the first terminal and the second terminal. The first terminal and the second terminal are only a general term, and in practical application, the terminal a may send a synchronous zooming request to the terminal B after performing zooming operation on a target picture, and correspondingly, the terminal B performs synchronous zooming processing on the locally stored target picture according to the synchronous zooming request; the terminal B may also send a synchronous zooming request to the terminal a after performing zooming operation on the target picture, and accordingly, the terminal a performs synchronous zooming processing on the locally stored target picture according to the synchronous zooming requirement, so that both the terminal a and the terminal B can send the synchronous zooming request to achieve synchronous zooming of the pictures of the first terminal and the second terminal, and thus, both the terminals can perform targeted and effective communication.
For example, referring to fig. 2, in an online view in practical application, a broker and a client view a house type diagram together, and when the broker explains the house type diagram for the client, the broker can specifically enlarge areas such as balconies, living rooms, bedrooms and the like in the house type diagram on the mobile phone. The server acquires scaling state data of the broker for the house type graph at the first terminal, and sends a house type graph synchronous scaling request to the second terminal (namely, a mobile phone used by a client for online watching). And the mobile phone (namely, the second terminal) used by the client receives scaling state data (namely, the corresponding area of the targeted amplification of the broker) of the house type graph of the broker, and performs synchronous scaling processing on the local house type graph to realize synchronous scaling of the house type graph.
In this embodiment, the first terminal receives a zoom operation performed by a user with respect to a target picture M1 of the first terminal, and obtains, by the server, zoom state data after the zoom operation is performed by the first terminal with respect to the target picture M1, where the zoom state data in this embodiment specifically includes a zoom multiple of the target picture M2 displayed after the zoom operation is performed by the user with respect to the target picture (original target picture M1) of the first terminal with respect to the original target picture M1, and a relative coordinate of a center point of the target picture M2 displayed after the zoom operation on the screen of the first terminal. For the relative coordinates of the center point of the target picture M2 on the first terminal screen, it should be noted that the coordinates of the picture center point of the current target picture M2 on the first terminal screen may be obtained by establishing a coordinate axis at the first terminal, and then dividing by the width and height of the screen, respectively, to obtain the relative coordinates of the center point of the target picture M2 on the first terminal screen. Therefore, knowing the magnification of the first terminal target picture M1 being enlarged or reduced and the ratio of the center point of the target picture M2 to the screen, the content and effect of the first terminal target picture shown on the screen can be determined.
In this embodiment, the second terminal receives a synchronous zooming request containing zooming status data sent by the first terminal to the second terminal, performs synchronous zooming processing according to the zooming status data, that is, performs zooming processing with the same magnification on the local target picture according to the zooming magnification, and performs positioning of the local target picture according to the relative coordinate of the center point of the target picture on the screen after zooming operation to achieve synchronous zooming of the picture, that is, the target picture with the same zooming effect as that on the screen of the first terminal is displayed on the screen of the second terminal, so that the second terminal can know the position of the center point of the target picture on the screen after acquiring the zooming status data, and then can zoom the locally stored target picture with a corresponding effect by combining the zooming magnification of the target picture, and by adopting the method, the data transmission amount can be reduced, thereby reducing the occurrence of stuck condition, and because the first terminal and the second terminal both store the target pictures to be synchronously zoomed, the definition is not limited.
For a better understanding of embodiments of the present invention, the following is presented in conjunction with FIG. 3 by way of example:
when the broker explains the house type diagram for the client, the broker can pointedly enlarge areas such as a balcony, a living room, a bedroom and the like in the house type diagram, and explains the special parts of the corresponding areas for the client through synchronous scaling of the client side, so that the client can listen to the corresponding areas and synchronously know the special parts of the corresponding areas, the broker and the client are established in the environment with the same latitude and the same picture, effective and clear-target communication is carried out, and the client experience is optimized. In the online watching process, when a client is interested in or has a question for a certain area P in the family graph, the client can make the broker know the area P concerned by the user through synchronous scaling, for example, the broker makes a key explanation for the area P amplified by the client, so as to solve the question of the user for the area P. Therefore, any party (client or broker) can perform scaling operation on the house type graph, and the house type graph picture after the scaling operation is synchronized to the opposite party terminal (such as a mobile phone and a tablet personal computer) in real time, so that the communication efficiency is improved, the user experience is optimized, and house transaction is facilitated.
As can be seen from the foregoing technical solutions, the method for synchronously zooming pictures across terminals according to the embodiments of the present invention can be applied in a scenario where a demand for synchronously zooming pictures exists between a first terminal and a second terminal, and specifically, in the embodiments of the present invention, first, zoom state data after a zoom operation is performed on a target picture by the first terminal is obtained, and then, a picture synchronous zoom request including the zoom state data is sent to the second terminal, so that the second terminal performs a synchronous zoom process on a local target picture according to the zoom state data, because the zoom state data includes a zoom multiple after the zoom operation is performed on the target picture and a relative coordinate of a center point of the target picture on a screen after the zoom operation is performed, when the second terminal receives the zoom state data, the second terminal can perform a synchronous zoom process on the local target picture to further achieve the synchronous zoom of the pictures of the first terminal and the second terminal, therefore, the embodiment of the invention can realize synchronous zooming of the pictures of the first terminal and the second terminal, thereby supporting the users of the first terminal and the second terminal to synchronously zoom in and zoom out for the corresponding areas on the target picture, and effective communication and communication are achieved, for example, when the user of the first terminal enlarges a certain area on the target picture and wants the user of the second terminal to see the enlarged area in a targeted manner, the first terminal only needs to perform picture zooming operation on the first terminal and send a picture synchronous zooming request to the second terminal, and accordingly, the second terminal can synchronously display the same picture as the zoomed picture of the first terminal, so that the situation that the corresponding area is easily amplified manually by a second terminal user only through language guidance is avoided, and the user experience is poor due to low communication efficiency; on the other hand, after the user at the first terminal performs the zooming operation on the picture, the user at the second terminal can synchronously sense the picture, so that the two terminals can effectively communicate the zoomed picture, thereby avoiding the situation of 'talking between chicken and duck' and being beneficial to the transmission of important information in communication; meanwhile, compared with a screen-casting software sharing screen, the screen-casting software sharing screen has the advantages that the data transmission amount is small, the blocking is not easy to cause, the definition of the picture is not limited, and the privacy of the two parties is protected.
On the basis of the foregoing embodiment, in this embodiment, after obtaining zoom state data after the first terminal performs a zoom operation on the target picture, the method further includes:
converting the zooming state data into zooming state data in a specified data format; the specified data format is a data format common to terminals of different operating systems.
In this embodiment, it can be understood that, when the first terminal and the second terminal adopt terminals of different operating systems, the zoom state data is converted into zoom state data in a data format that can be commonly used by the first terminal and the second terminal, and because the data format of the current zoom state data is the common data format, the second terminal is convenient to receive the zoom state data, and meanwhile, the zoom state data is also converted into the data format of the operating system corresponding to the current second terminal.
In this embodiment, it can be understood that when the first terminal and the second terminal adopt different operating systems, for example, when the first terminal is an Android terminal, and the second terminal is an iOS terminal; in order to realize synchronous zooming of pictures across terminals, zooming state data can be converted into zooming state data in a specified data format, namely, a data format common to an Android terminal and an iOS terminal, such as a jsonnstring data format. The zoom state data are converted into the zoom state data in the data format common to the Android terminal and the iOS terminal, so that the data format conversion of the terminal on the other side (the second terminal) is facilitated, the data format corresponding to the terminal on the other side is converted, the synchronous zooming of the pictures of the first terminal and the second terminal is realized, the synchronous zooming of the pictures can be realized by different terminal systems, and the problem that the synchronous zooming of the pictures across the terminals cannot be realized if the mobile phone used on the client side is the Android mobile phone and the mobile phone used on the broker side is the IPhone mobile phone is solved.
As can be seen from the foregoing technical solutions, in the cross-terminal image synchronous scaling method provided in the embodiments of the present invention, the scaling state data is converted into the scaling state data in the specified data format, which is beneficial to the other terminal (the second terminal) to perform data format conversion, and meanwhile, when the operating systems of the first terminal and the second terminal are different, synchronous scaling of images of the first terminal and the second terminal can still be achieved.
On the basis of the foregoing embodiment, in this embodiment, when terminals of different operating systems include an Android terminal and an iOS terminal, the specified data format is a JsonString data format, and accordingly, the specifying of the zoom state data of the data format includes:
the zoom attribute is used for representing zoom multiple data of the first terminal after zooming operation is carried out on the target picture;
and the position-X attribute and the position-Y attribute are used for representing the relative coordinates of the center point of the target picture on the screen after the first terminal performs the zooming operation on the target picture.
In this embodiment, it should be noted that, when socket transmits data in Java, objects are packed into JSON strings for transmission, "zoom" is a proprietary attribute of IE browser, and can be used under ios and android, and hasLayout can be triggered through "zoom". The position attribute specifies the type of position of the element, which defines the positioning mechanism used to establish the layout of the element, any element can be positioned, but an absolute or fixed element will generate a block-level box, regardless of the type of the element itself, and the relative positioned element will be offset from its default position in the normal stream.
In the present embodiment, referring to fig. 4, for example, the data type is the JsonString data format
According to the above technical solution, the cross-terminal image synchronous zooming method provided by the embodiment of the present invention designates the data format as a JsonString data format, which is beneficial to realizing the image synchronous zooming of the first terminal and the second terminal.
On the basis of the foregoing embodiment, in this embodiment, sending a picture synchronization zoom request including zoom state data to a second terminal, so that the second terminal performs synchronization zoom processing on a local target picture according to the zoom state data, includes:
sending a picture synchronous zooming request containing zooming state data to the second terminal, so that the second terminal performs synchronous zooming conflict detection before performing synchronous zooming processing on the local target picture according to the zooming state data, and performs synchronous zooming processing on the local target picture according to the zooming state data when determining that no synchronous zooming conflict exists.
In this embodiment, in order to avoid a situation that one terminal always operates to zoom a picture and the other terminal cannot perform a picture zooming operation due to a continuous operation of the other terminal, before a picture synchronization zooming request including zooming state data is sent to the second terminal, so that the second terminal performs a synchronization zooming process on a local target picture according to the zooming state data, a synchronization zooming conflict detection needs to be performed through a synchronization zooming conflict resolution mechanism, where the synchronization zooming conflict resolution mechanism may determine whether a picture synchronization zooming request sent by the first terminal is received within a preset time period, and if so, determine that a synchronization zooming conflict exists, otherwise, determine that no synchronization zooming conflict exists. And when the synchronous zooming conflict does not exist, carrying out synchronous zooming processing on the local target picture according to the zooming state data.
As can be seen from the above technical solutions, in the method for synchronously zooming a picture across terminals provided by the embodiment of the present invention, by performing synchronous zooming conflict detection, when a synchronous zooming conflict occurs, a current picture synchronous zooming request is not sent, and when it is determined that no synchronous zooming conflict exists, a second terminal performs synchronous zooming processing on a local target picture, thereby avoiding that a first terminal continuously performs zooming operation on the target picture, which brings poor experience to a second terminal user; meanwhile, the situation that the second user terminal continuously analyzes the zooming state data sent by the first user terminal, and the second user terminal is blocked or even crashed due to the fact that the data transmission quantity is too large is effectively avoided.
On the basis of the foregoing embodiment, in this embodiment, sending a picture synchronization zoom request including zoom state data to the second terminal, so that the second terminal performs synchronization zoom conflict detection before performing synchronization zoom processing on a local target picture according to the zoom state data, includes:
sending a picture synchronous zooming request containing zooming state data to a second terminal, so that the second terminal judges whether the picture synchronous zooming request sent by the first terminal is received within a preset time period before carrying out synchronous zooming processing on a local target picture according to the zooming state data, if so, determining that synchronous zooming conflict exists, otherwise, determining that the synchronous zooming conflict does not exist.
In this embodiment, it should be noted that, in a preset time period, it is a time period before a picture synchronization zooming request currently sent by the first terminal, whether the first terminal has sent a request message of this type. For example, the preset time is 5 seconds, the current 10 o ' clock 01 min 10 seconds, the first terminal sends a picture synchronization zooming request Q2 (for example, a picture in a living room is zoomed in 1.5 times), synchronous zooming conflict detection is performed, that is, it is determined whether the picture synchronization zooming request Q1 sent by the first terminal is received (for example, a picture in a living room is zoomed in 1.5 times, or a picture in a living room is zoomed in 2 times, or a picture in a living room is zoomed in 1.5 times, or a picture in a bedroom is zoomed in 2 times, etc.) between 10 o ' clock 01 min 05 seconds and 10 o ' clock 01 min 10 seconds, and if a picture synchronization zooming request Q1 is sent, a synchronization; if the synchronous zooming request Q1 is not sent, that is, there is no synchronous zooming conflict, the synchronous zooming request is sent.
As can be seen from the above technical solutions, in the method for synchronously zooming pictures across terminals provided in the embodiments of the present invention, whether a synchronous zooming request of a picture sent by a first terminal is received within a preset time period is determined, if yes, a synchronous zooming conflict is determined to exist, otherwise, no synchronous zooming conflict is determined to exist, so that a user sets a corresponding preset time for different zooming state data transmission amounts, sufficient time is provided for reading zooming state data received each time, and meanwhile, the first terminal is prevented from continuously performing a target picture zooming operation, which brings a poor experience to a second terminal user.
On the basis of the foregoing embodiment, in this embodiment, if the first terminal is an iOS terminal and the first terminal adopts a uikit.
Reading UIKit, UIScrollView and zooScale, and obtaining the scaling multiple of the first terminal after scaling operation is carried out on the target picture;
reading UIKit, UIScrollView, frame, origin, x and UIKit, UIScrollView, frame, origin, y, and obtaining the relative coordinates of the center point of the target picture on the screen after the first terminal performs the zooming operation on the target picture.
In this embodiment, it should be noted that UIImageView is an image control that displays a single image or animation in an interface, and the UIImageView object displays any sequence of image interfaces of images or animations.
For better understanding of the present embodiment, for example (synchronizing the first terminal as the iOS terminal to the second terminal as the iOS terminal):
and the iOS terminal displays the picture by using the UIKit. UIImageView control, and then wraps the picture by using the UIKit. UIScrollView to realize the picture zooming effect. When a first terminal user zooms a target picture, obtaining a target picture zooming multiple by reading UIKit. Reading UIKit. UIScrollView. frame. origin. x and UIKit. UIScrollView. frame. origin. y, calculating the coordinates of the center point of the current target picture on the screen, and dividing the coordinates by the width and the height of the screen respectively, thereby obtaining the relative coordinates of the center point of the target picture on the screen. And obtaining picture data to be sent, namely zooming state data after the first terminal performs zooming operation on the target picture.
The Android terminal displays the picture control as Android, widget, ImageView and the ScaleType as MATRIX; and converting the received zooming state data into a picture state matrix to achieve the effect of picture zooming.
As can be seen from the foregoing technical solutions, the method for synchronously zooming a picture across terminals provided by the embodiment of the present invention can acquire zoom state data of a target picture after a zoom operation is performed on the target picture by a first terminal when the first terminal is an iOS terminal.
On the basis of the foregoing embodiment, in this embodiment, if the first terminal is an Android terminal, the first terminal adopts an Android.
Reading matrix, MSCALE _ X and matrix, MSKEW _ Y in a state matrix of a target picture, and obtaining a zoom multiple of a first terminal after zooming operation is performed on the target picture;
