| Abstract: | In the first place, how to capture the Windows and Linux desktop graphic images was described, using their API functions. Then a lossless encoding arithmetic based on gridding was put forward, according to the characters of desktop graphic image sequences. The experiment results show that this arithmetic can compress the desktop graphic image sequences effectively and can meet actual application demands. |
