Abstract
A method for dynamically scaling a picture as required in request comprises the following steps: storing an original picture in a source directory; sending a request for downloading the picture to a server by a client, and appointing a picture source mark and a needed size; finding the needed picture according to the source mark carried in request parameters when receiving the request of the client; scaling the picture according to the size carried in the request parameters; storing the scaled picture in a temporary cache directory, and resorting the scaled picture in a memory for a period of time; sending the picture to the client; when receiving the request of the client again, firstly searching whether a picture with the size exists in the memory and then searching in the temporary cache directory by the server end; and clearing the temporary cache dictionary regularly. When the request of the client is received, the invention dynamically scales the picture and utilizes the cache to improve the efficiency.
Description
Technical field
The present invention relates to a kind of in when request dynamic method of scaling pictures as required, particularly a kind of can be when the client downloads picture, server end comes the method for dynamic scaling pictures according to the needed dimension of picture of client.
Background technology
When server end provided picture resource to client, every kind of client may need different dimension of pictures, if server end is stored eurypalynous picture like this in advance, will have very big storage pressure, and was difficult to reckon with the how many kinds of size.The present invention will provide a kind of way, can be when receiving client-requested, and dynamically scaling pictures, and use caching technology is raised the efficiency.
Summary of the invention
It is a kind of in when request dynamic method of scaling pictures as required that the present invention will provide.
Of the present invention a kind of in when request dynamic method of scaling pictures as required, this method comprises following steps at least:
Step 1: original image is stored in the Resource TOC.
Step 2: user end to server is initiated the request of download pictures, and designated pictures resource identification and required size.
Step 3: when receiving client-requested, according in the required parameter with resource identification, find needed picture.
Step 4: with picture according in the required parameter with size scaling.
Step 5: the picture of convergent-divergent is stored in the interim CACHE DIRECTORY, and within a period of time, is trapped in the internal memory.
Step 6: picture is sent to client.
Step 7: when receiving client-requested once more, server end will be sought earlier the picture whether this size is arranged in internal memory, in interim CACHE DIRECTORY, seeks again, if can not find, and repeating step 3 more then.
Step 8: the interim CACHE DIRECTORY of periodic cleaning.
Of the present invention a kind ofly in when request dynamic method of scaling pictures as required original image is stored in the Resource TOC the steps include:
Step 11: need organize picture by certain rule, can locate picture according to resource identification fast.
Step 12: need to consider that picture too much can cause the problem that reading speed is slack-off in the same catalogue, according to resource ID with picture-storage in suitable subdirectory.
Of the present invention a kind of in when request dynamic method of scaling pictures as required, with picture according in the required parameter with size scaling, the steps include:
Step 41: if the width of appointment only, the then dynamic convergent-divergent of height.
Step 42:, then finally can be scaled width and highly all be not more than the picture of the bi-directional scaling of specified size if specified width and height simultaneously.
The invention enables when receiving client-requested, dynamically scaling pictures, and use caching technology is raised the efficiency.
Description of drawings
Fig. 1 is a flow chart of the present invention.
Embodiment
Referring to Fig. 1, key step of the present invention is as follows:
Step 1: original image is stored in the Resource TOC.
Step 2: user end to server is initiated the request of download pictures, and designated pictures resource identification and required size.
Step 3: when receiving client-requested, according in the required parameter with resource identification, find needed picture.
Step 4: with picture according in the required parameter with size scaling.
Step 5: the picture of convergent-divergent is stored in the interim CACHE DIRECTORY, and within a period of time, is trapped in the internal memory.
Step 6: picture is sent to client.
Step 7: when receiving client-requested once more, server end will be sought earlier the picture whether this size is arranged in internal memory, in interim CACHE DIRECTORY, seeks again, if can not find, and repeating step 3 more then.
Step 8: the interim CACHE DIRECTORY of periodic cleaning.
Above-mentioned steps 1 with the concrete steps that original image is stored in the Resource TOC is:
Step 11: need organize picture by certain rule, can locate picture according to resource identification fast.
Step 12: need to consider that picture too much can cause the problem that reading speed is slack-off in the same catalogue, according to resource ID with picture-storage in suitable subdirectory.
Above-mentioned steps 4 with picture according in the required parameter with the concrete steps of size scaling be:
Step 41: if the width of appointment only, the then dynamic convergent-divergent of height.
Step 42:, then finally can be scaled width and highly all be not more than the picture of the bi-directional scaling of specified size if specified width and height simultaneously.
When the client downloads picture, server end can come dynamic scaling pictures according to the needed dimension of picture of client when technique scheme was implemented.
It should be noted last that above embodiment is only in order to explanation and unrestricted technical scheme described in the invention; Therefore, although this specification has been described in detail the present invention with reference to the above embodiments,, those of ordinary skill in the art should be appreciated that still and can make amendment or replacement to the present invention with being equal to; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in the middle of the claim scope of the present invention.
