I have one more question. Do you think that using TiffReadScanline could improve the reading performance (or at least would have the same performance)? In case of one-strip big files temporary buffer becomes quite ...big - that's why I think about TiffReadScanline.

TiffReadScanline usually performs well. Assuming infinite memory, it will never be faster than reading whole strips. But TiffReadScanline may have access which allows it to (often) use memory more efficiently than reading the whole strip. Libtiff also supports a strip-chopping feature which may allow large strips to be presented as a set of smaller strips (depending on compression type).
