In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the drawings are described in detail below. It is to be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application. It should be noted that, for the convenience of description, only a part related to the present application is shown in the drawings, and not all structures are shown.
In a scene of transmitting pictures between devices, pictures to be transmitted may belong to pictures with relatively fixed formats, for example, pictures related to an identity card, a honor certificate, a public certificate, and the like, and the common characteristics of the pictures are as follows: most pictures have the same content, and only a few characters have different content, and in the embodiment of the application, the pictures are recorded as template pictures. At present, template pictures are transmitted between devices, original pictures can be directly transmitted, the original pictures are often influenced by factors such as picture size and network bandwidth, and the defects of long transmission time, high network traffic consumption and the like exist. Or template pictures are transmitted between devices, and compressed pictures obtained by compressing original pictures can also be transmitted, although the mode can accelerate the transmission of the pictures and reduce the consumption of network flow, the definition of the pictures to be transmitted is reduced, the quality of the pictures is influenced, and the requirements of users cannot be met.
Based on this, this application embodiment provides a picture transmission's system, the system includes: a first device and a second device, wherein: the first device is configured to send a first template identifier and key information of a first picture to be sent to a second device, where the data format of the key information is a character string, and the first template identifier is used to indicate first template information corresponding to the first picture; the second device is configured to obtain the first template information according to the first template identifier, and generate a second picture file according to the first template information and the key information, where the second picture file is matched with the first picture, and the second picture file is used by the second device as the first picture.
It can be seen that if the first device transmits a picture to the second device, the first device may send the template identifier and the key information of the picture to be transmitted to the second device in the form of a character string, and does not need to transmit the picture to be transmitted in the picture format with a large data volume to the second device, thereby reducing the interactive data volume between the first device and the second device. Therefore, according to the technical scheme provided by the embodiment of the application, the occupation of network resources by the pictures transmitted between the devices is reduced, the transmission time is shortened, the transmission efficiency is improved, and the quality of the pictures received by the receiving device is not influenced.
For facilitating understanding of a specific implementation of the system for picture transmission provided in the embodiments of the present application, reference will be made to the following description in conjunction with the accompanying drawings.
Fig. 1 is a schematic structural diagram of a system 100 for transmitting pictures according to an embodiment of the present disclosure. Referring to fig. 1, the system 100 may include a first device 101 and a second device 102. Wherein:
the first device 101 is configured to send a first template identifier and key information of a first picture to be sent to the second device 102, where the data format of the key information is a character string, and the first template identifier is used to indicate first template information corresponding to the first picture.
The second device 102 is configured to obtain the first template information according to the first template identifier, and generate a second picture file according to the first template information and the key information, where the second picture file is matched with the first picture, and the second picture file is used by the second device 102 as the first picture.
Before transmitting the picture between the first device 101 and the second device 102, the second device 102 may obtain a plurality of pieces of template information and a template identifier of each piece of template information, and store the template information and the template identifier correspondingly. The corresponding relationship between the template information and the template identifier stored in the second device 102 at least includes the corresponding relationship between the first template information and the first template identifier.
The template identifier may be a template name, such as an identity card template or an electronic certificate template. Alternatively, the template identifier may be a template index, such as 1 or 2, where 1 may be used to indicate an identity card template and 2 may be used to indicate an electronic certificate template.
The template information may include at least one of an icon, a background picture, and format information. The format information may be, for example, at least one file with cs suffix for indicating the format of various elements in the picture, for example, cs file 1 is for indicating that the font of the text in the picture is regular font and the font size is 5, and cs file 2 is for indicating that the line spacing of the text in the picture is 23 pounds.
As an example, the second device 102 may download the correspondence between the template information and the template identification from the first device 101.
As another example, the second device 102 may also download the corresponding relationship between the template information and the template identification on a trusted remote device (e.g., a cloud server). In order to synchronize the correspondence between the template information and the template identifier stored in the second device 102 with the first device 101, the first device 101 may also download the correspondence between the template information and the template identifier from a trusted remote device (e.g., a cloud server); alternatively, the trusted remote device (e.g., a cloud server) may also actively synchronize the template information and the template identifier downloaded by the second device 102 to the first device 101.
As yet another example, the technician may also configure the correspondence between the template information and the template identification on the second device 102.
In any implementation manner of this example, for a template picture belonging to one template, the second device 102 only needs to obtain the template picture once and store the template picture locally, and the corresponding relationship between the template information and the template identifier does not need to be obtained once when the template picture belonging to the template is received each time, so that transmission of redundant data between devices can be effectively saved, and the utilization rate of network resources is improved.
In some implementations, the first device 101 determines that the first picture to be transmitted completely matches the first template information, and then the first device 101 may extract only difference information between the first picture and the first template information as key information, and thus the second device 102 is specifically configured to: rendering the difference information and the first template information to obtain the second picture file. The first picture is completely matched with the first template information, which may mean that the first picture is completely identical to the first template information except for the difference information, for example, the first picture is an identification card photo of a, the first template information is an identification card template, and the difference information is personal information of a on the identification card, so that the first picture and the first template information are completely matched.
In other implementation manners, the first device 101 determines that the matching degree between the first picture to be transmitted and the first template information reaches a preset value, then, the first device 101 may only extract difference information between the first picture and the first template information, note different matching items in the first picture and the first template information as template update information, and take the difference information and the template update information as key information, so that the second device 102 is specifically configured to update the first template information according to the template update information to obtain second template information, and render the difference information and the second template information to obtain the second picture file. For example, if the first picture is the electronic certificate 1, the template information of the electronic certificate 1 is the template information 1, and the first template information is the template information 2 of the electronic certificate 2, then if 90% of the contents in the template information 1 and the template information 2 are the same, it can be regarded that the matching degree of the first picture and the first template information reaches the preset value.
In this implementation manner, in order to enrich templates and facilitate better use of the system 100 for transmitting pictures provided in the embodiment of the present application, the second device 102 is further configured to store the second template information and send the corresponding relationship between the second template information and the second template identifier to the first device 101; the first device 101 is configured to store a corresponding relationship between the second template information and the second template identifier.
The format of the second picture file may be a picture in a format such as JPG or GIF, or may be a text in a format such as Word or PDF.
As can be seen, with the system 100 for transmitting pictures provided in the embodiment of the present application, the first device 101 may send the template identifier and the key information of the picture to be transmitted to the second device 102 in the form of a character string, and the picture to be transmitted in the picture format with a large data amount does not need to be transmitted to the second device 102, so that the data amount of interaction between the first device 101 and the second device 102 is reduced, and the second device 102 may generate a picture text that can be used as the picture to be transmitted based on the received character string and the template information corresponding to the locally stored template identifier, thereby completing the purpose of transmitting the picture to the second device 102 by the first device 101. Therefore, the occupation of network resources by pictures transmitted between devices is reduced, the transmission time is shortened, the transmission efficiency is improved, and the quality of the pictures received by the receiving device is not influenced.
