Description
Technical field
The present invention relates to the multi-media image technical field, be specifically related to a kind of method for packing of multimedia image data, can be applicable in the smart mobile phone.
Background technology
Multimedia is the combination of computing machine and video technique, and in fact it is two medium; Sound and image are perhaps used present term: sound equipment and TV.Multimedia itself has two aspects, the same with all modern technologies it be by hardware and software, or machine and thought are mixed and are formed.Can be with multimedia technology and function in conceptive control system and the information divided into.Why multimedia can realize it being to rely on digital technology.Multimedia is represented converging of digital control and Digital Media, and computer is a digital control system, and Digital Media is state-of-the-art storage of current Voice & Video and mode of propagation.Multimedia computer need have the ability stronger than main flow computer, and multimedia computer has determined the development of main flow computer.The main thing of difference common computer and multimedia computer is sound card and CD-ROM driver.CD is multimedia main storage and switched-media.
Image is one of multimedia bearing mode, and it is a kind of form of describing things geometric properties, form, position and size with point, line, symbol, literal and numeral etc.
Existing common view data method for packing has following several kinds:
1, the BMP form;
2, the GIF form;
3, jpeg format;
4, the JPEG2000 form;
5, tiff format;
6, the PSD form;
7, the PNG form;
8, the SWF form;
9, the SVG form;
10, the JPG form;
Other picture format as:
