Hi Spark. If we want to convert 8M to QVGA (320*240), it will be fast . It is because JPEG is 8*8 Matrix , so we only need use the DC data (select some pixel ) . No need using AC data so No need to do the IDCT
But unfortunately , the default android screen is VGA ( 640＊480 ＝ 0.25M ). Resize 8M to 0.25M RGB will be slow. --~--~---------~--~----~------------~-------~--~----~ unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting -~----------~----~----~----~------~----~------~--~---
