Is there any tool in libtiff to easily extract a region?

Sure, just spit out rows twice while processing.

You don't really give enough context to help further.

The tricky part is, that any suggestion like 'ImageMagick' is not helpful. We are developing an embedded system, so no X. And not much of processing power.

I consider it a wastage of resources, to always do something like

'tifftopnm | {pnmscale | pnmcut} |  pnmtotiff'.

Any faster suggestion is welcome,
