Also, I may only want to read the first N pixels ..lets say the interesting data was in the first N pixels ..then why read the remaining? If the ReadStrip is done several times(lets say 10000 rows) then each time we end up reading M pixels (M >> N) rather than N..and this does cause a performance hit..

It sounds like you will need to write your own TIFF reader in order to satisfy these many complex objectives.
