It seems multiple-strips also can do such things like single-strip.(JPEG-IN-TIFF files). and i try to do like this, but it need another marker: called DRI? I was puzzled how(where) to get the DRI value? in the tif file?

do anyone know something about this? any kind of information that related to this problem is ok.

When a jpeg stream is coded, codec can be instructed to emit "restart marker" every "restart interval" count MCU block. Restart interval is indicated by DRI marker, so the decoder can know...

You can find info, on how all these is writen, in jc(jd)marker.c, of libjpeg.
