The test of Photosynth is entirely because of this "super abnormal new Bing map ".ArticleSee the so-called Photosynth technology. In fact, this is a photo stitching technology. It is very powerful and can splice many photos into a continuous photo. It is a bit similar to Google Street View, but it is two completely different technologies, maybe I like Google Street View better. For Microsoft's Photosynth technology, I think it should be nice to use it easily to do some small things. For example,
Sun's JRE provides the following L FS:
CrossPlatformLookAndFeel-This is the "Java L F" (also called "Metal") that looks the same on all platforms. It is part of the Java API (javax.swing.plaf.metal) And is the default that will be used if you do nothing in your code to set a different L F.
SystemLookAndFeel-Here, the application uses the L F that is native to the system it is running on. the system L F is determined at runtime, where the application asks the system to return the name o
1, double hit the lower right corner of the task bar of the Yellow trumpet, (if not, you can open the Control Panel in the "Multimedia" and then select the "Show volume control in the taskbar" point to determine the yellow trumpet will appear in the lower right corner of the computer screen on the taskbar. )
2, double click the small horn, you can see a set of options, please see whether there are the following five options, if it is five, then proceed to the 5th step, if there is no five words

Mad_decoder can be seen as the "core" structure of the entire decoder. It realizes some functions of object-oriented language by using the finite object mechanism of C language. The decoder encapsulates all the necessary components of a decoding process, including user-defined messages, 6 callback functions, and corresponding options. The mad_decoder structure is defined in the Decoder.h header file:
struct Mad_decoder {enum mad_decoder_mode mode; int options; struct {long pid; int in; int out;}
