In one of the embodiments, efficiency is shared in order to further improve, step S203 includes：
A1：Coordinate transformation parameter is compressed, obtains compressed file；
The less file of occupied space can be obtained after coordinate transformation parameter is compressed, easy to store.
A2：The compressed file is encrypted, obtains encryption file；
It is security in order to ensure coordinate transformation parameter that compressed file, which is encrypted, in one of the embodiments,
It can be encrypted by the way of symmetric cryptography, so as to improve encryption efficiency.
A3：The encryption file is converted into two-dimension code image；
The character for encrypting file is directly converted into Quick Response Code by the present embodiment, generates two-dimension code image.For example it can use
The Zxing storehouses increased income, are realized using the storehouse character for encrypting file changing into Quick Response Code, so as to generate two-dimension code image.At it
Can be directly by scanning the two-dimensional code in his handheld device decoding process, you can obtain the letter with coordinate transformation parameter content
Breath.The efficiency for obtaining coordinate transformation parameter is improved, shares efficiency so as to improve.
A4：The two-dimension code image is shared by the mobile application with the mobile application of other handheld devices.
Directly two-dimension code image is shared, the convenience that user uses can be improved.Also, change Quick Response Code process
In be that will directly encrypt file content in itself to be changed, in follow up scan, you can obtain the content of encryption file in itself,
So and need not pay close attention to what form third-party Parameter File is, file can be directly decrypted and be decoded, obtain
Original document.
Further, it is described that the encryption file is converted into two-dimension code image step, including：
Encryption identification and encryption key are configured to the encryption file, wherein, the encryption identification is to be used to distinguish
The mark of difference encryption file；
The encryption key and the encryption file are converted into two-dimension code image, and in the two-dimension code image in plain text
Show the encryption identification.
It can be encrypted by way of encryption key is set, and by way of encryption identification is set.Encryption identification
Relevant with encryption file, different encrypted file-encryption marks is different, it is therefore an objective to facilitates user to identify the Quick Response Code figure
The corresponding coordinate transformation parameter of piece whether be user demand coordinate transformation parameter.
In one of the embodiments, sharing method of the invention further includes：
Two-dimension code image is received, by scanning the two-dimension code image, is converted into encryption file；
The encryption file is decrypted, obtains decryption file；
The decryption file is decompressed, obtains coordinate transformation parameter.
The some technical characteristics can be applied in the receiving terminal shared.As receiving terminal, by the two-dimension code image of reception into
Row scanning, you can obtain encryption file, without obtaining encryption file by way of link, substantially increase acquisition encryption file
Efficiency.

Holding equipment can both be used as transmitting terminal, can also be used as receiving terminal.Handbook is subjected to establishment android system, and creates wechat
Using.The coordinate transformation parameter of acquisition is compressed, and is encrypted using symmetric cryptography mode, is then opened using ZXing
Source instrument generation two-dimension code image, two-dimension code image include encryption identification, encryption key and encryption file.Then by Quick Response Code
Picture is transmitted to other handbooks by wechat.
The application with sharing function that two-dimension code image can be carried by Android carries out sharing propagation, such as, it is blue
Tooth, short message, mail etc..Since android system has been provided for good sharing interface in itself, and many third parties are social
Open SDK secondary development bags are also provided using (such as wechat, QQ, Sina weibo etc.), sharing function is supported in perfection, therefore
Based on these, conveniently sharing mechanism carries out software development, and the coordinate transformation parameter being just easily achieved between multi-user is total to
Enjoy.Such as can be shared by modes such as short message, mail and bluetooths, can also by creating some common social networking applications,
The approach for making to share is with regard to more, also more close to intelligentized mobile application user experience.
Above entirely by being encrypted into decryption during, coordinate parameters are all that use is showed in the form of two-dimension code image
Family, operation user can not be related to the particular content of encryption parameter, but be applied by means of colourful Android, Ta Menyou
It quickly can timely get newest coordinate parameters and be used for operation, convenient management and operation.
While user job needs are met, this programme provides encryption, the opening decrypted and shared of complete set
Interface, there is provided used to third party manufacturer.Since what is reduced during decryption is the content of original document in itself, so and need not close
The Parameter File for noting third party manufacturer is any form, after the decryption method provided by scheme is resolved to original file content,
Each manufacturer can carry out the extraction of parameter according to own files form, i.e. this programme provides a kind of general, open seat
Mark parameter shares the method with propagating, and being based on this scheme easy to third party manufacturer carries out secondary development.
