Specifically, the form for the original image for needing to be cut may include multiple format, such as common JPG,
JPEG, BMP, PNG etc., may also include some uncommon forms, cause system can not open and be converted.
In step S502, judge that the format information for obtaining original image whether there is in supported format list.
Specifically, the database of the format list of the supported picture of system is previously stored with systems, by step
After the picture format information that S501 is obtained, according to lookup in the format list in the format information to database and match, if
Identical format information is found, then shows that current system can support the cutting zoom operations of the picture of the form, it is not necessary into
Row format converts.
It is supported form by the format conversion of the original image of acquisition if being not present in step S503.Due to each
The form of kind picture depends primarily upon the compression algorithm of picture, therefore, before format conversion is carried out to original image, in system
The compression algorithm of various pictures is also preserved in database, the conversion of data format is carried out according to algorithm, the system of obtaining can be supported
Picture format picture.
In addition, another embodiment preferably as the embodiment of the present invention, in the step according to the spy to prestore
Reference ceases, and after determining position of the characteristic information in original image, the size according to characteristic information is further included, according to picture
Original scale zooms in and out original image, the size of one of dimension of the characteristic information after scaling is equal to Target Photo
