The second embodiment
The process flow diagram of the client skin picture method for drafting that Fig. 2 provides for the second embodiment.As shown in Figure 2, the client skin picture method for drafting of the present embodiment comprises the following steps:
Whether step S21, judging to store in the local storage of user terminal needs the skin picture file drawn.
Needing the skin picture file of drawing can be the picture file having had in local storage, can be also the picture being stored in the webserver.For example, user terminal can be according to the user who detects the selection instruction on interface as shown in Figure 3, whether judgement needs the skin picture file of drawing to be stored in local storage.For example, if user selects is to recommend in client end interface under background item, with the picture (as picture 2) of prompting download, to illustrate that this picture file is stored in the webserver, need to calls network interface and download this picture file; If user selects, it is the picture (as picture 6) of recommending in client end interface under background item not with prompting download, illustrate that this picture file is former once used skin picture file, this skin picture file is stored in the local storage of user terminal, only need from local storage, read out this skin picture file.
If the determination result is NO for step S21, perform step S22: by network interface, download original image file.
By network interface from background server obtain with the skin picture file that needs to draw with respect to URL address (the Uniform Resource Locator of original image file, URL(uniform resource locator)), then according to the URL address of this original image file, download and obtain this original image file.The file registration code (filekey) that at least comprises this original image file in URL address.
Step S23, carries out transcoding to original image file.
Original image file can be TIFF (TaglmageFileFormat), GIF (Graphics Interchange Format, graphic interchange format), JPEG(joint Photographic Experts Group, JPEG (joint photographic experts group)), any in the form such as PNG (Portable Network Graphics, portable network image).
Original image file is converted to BMP(bitmap, bitmap) picture file of form.
According to the difference of the operating system of user terminal, can select the mode of asynchronous transcoding or synchronous transcoding to carry out transcoding, as: if the operating system that user terminal is used is Saipan system (symbian), can adopt the mode of asynchronous transcoding to carry out transcoding; If the operating system that user terminal is used be Android system (Android) preferably the mode of synchronous transcoding carry out transcoding.Asynchronous transcoding refers to that operating system also can carry out other processes when carrying out transcoding process, and synchronous transcoding refers to that operating system no longer carries out other processes when carrying out transcoding process.
Step S24, encrypts the original image file after transcoding, generates skin picture file and preserves.
The concrete implementation step of step S24, can be as shown in Figure 4:
At step S241, the original image file after transcoding is encrypted.
Can be encrypted by the original image file after for transcoding by the encryption function Encrypt in class Crypt.Concrete cryptographic algorithm is prior art, does not repeat them here.
In addition; after encryption, also the original image file after original image file and transcoding can be deleted; thus; what user found can only be the original image file after the transcoding after encrypting; thereby can more effectively prevent that user from arbitrarily revising original image file, further solve the Copyright Protection of this original image file.
At step S242, for skin picture file renames.
Can be according to the filekey in the URL address of the original image file corresponding with skin picture file obtaining in step S22 and the purposes of this skin picture file, for skin picture file renames, for example, suppose skin picture file to be used as user's business card background picture of client, filekey in the URL address of the original image file corresponding with skin picture file obtaining in step S22 renames skin picture file after encrypting into 0204503434335aff381300ffff52ff35CardBackground for " 0204503434335aff381300ffff52ff35 " and character " CardBackground ".
Filekey is that background server utilizes MD5(Message Digest Algorithm5, Message Digest Algorithm 5 according to original image file) character string of 16 bytes calculate obtaining, there is uniqueness.Therefore utilize filekey to come for skin picture file designation in conjunction with the purposes of skin picture file, can avoid occurring the problem of skin picture file after encrypting and the repetition of other skin picture file.
Step S243, is stored in skin picture file in local storage.
Step S25, reads skin picture file and it is decrypted.
From local storage, read skin picture file, and can be encrypted by the original image file after for transcoding by the decryption function Decrypt in class Crypt.Concrete decipherment algorithm is prior art, does not repeat them here.
Step S26, whether judgement deciphering is successful.
If step S26 judgment result is that successful decryption, perform step S27: load the image data in the skin picture file after deciphering, image data is plotted on the interface of client.
Before drafting, can to the image data in the skin picture file after deciphering, adjust according to the size of client end interface, so that it is more suitable for showing on client end interface.
In addition, above-mentioned according to the size of client end interface, the step adjusted of image data in the skin picture file after to deciphering also can be at step S24: before the original image file after transcoding is encrypted, carry out, like this except drawing for the first time, thereafter each while drawing identical skin picture file just without adjusting again, thereby can improve the efficiency of drafting skin picture file.
If step S26 judgment result is that deciphering is unsuccessful, perform step S22: by network interface, download original image file.
If decipher unsuccessful, illustrate that skin picture file is not a legal skin picture file, this skin picture file is not encrypt file or was once modified, and now, will again by network interface, download the original image file corresponding with this skin picture file yet.Can effectively prevent that like this original image file because being modified and the interface of client from not mating the drafting failure that causes, showing the problems such as abnormal.
If judgment result is that of step S21 is to perform step S25: read skin picture file and it is decrypted from local storage.
If store in the local storage that judgment result is that user terminal of step S21, need the skin picture file of drawing, directly from this locality storage, wherein read this skin picture file.Because skin picture file is the file after transcoding, therefore except drawing for the first time, each while drawing identical skin picture file thereafter, all no longer need original image file to carry out transcoding, thereby can improve the efficiency that skin picture is drawn.
The embodiment of the present invention provides client skin picture method for drafting, by transcoding original image file, and will after the original image file encryption after transcoding, save as skin picture file, in the time need to drawing skin picture at every turn, read, decipher and load the image data in skin picture file, and this image data is plotted on the interface of client, can omit except drawing for the first time, the step of transcoding original image file during each drafting skin picture, thereby improve the drafting efficiency of skin picture, and can prevent that user from arbitrarily revising original image file or being diverted to other purpose, thereby can effectively protect the image data of client skin picture file, solve the Copyright Protection of client skin picture file.
