Use the iimage interface under wince to process JPEG, BMP, PNG, and other format images

I used the iimage interface in the project and found that the function is very powerful. Now I feel that the only drawback is the speed problem. I had to handle many format pictures and write the encoding/decoding by myself, I wrote a BMP file, because the BMP RGB data is well read, and it is easy to save the BMP file. The encoding and decoding of compressed files such as JPEG is very troublesome, and my level is limited, the iimage interface can be used to convert images of various formats. In wince, the GDI drawing only supports the BMP file format, to load JPEG and PNG files, you can only convert them to BMP files. Fortunately, the iimage interface is found, and all functions under the iimage interface are used in imaging. h down
