Hi Mark, AFAIK, the decoder of jpeg on android must support to read
random part of jpeg file if I want do step#2 as you said.
I checked out SDK reference and found out the default decoder of jpeg
seems not support it. Am I right?
Do I have to make another jpeg decoder?

BTW, I think google map does the same thing on server side, not on
mobile phone, does not it?
