Re: [Lcms-user] Searching for a way to use tifficc inside a pipe

[<ma...@li...>]

Hi,

After some investigation, I realize pipes cannot be used at all, since
Libtiff does require random access. Sorry, but the temporary
storage seems the only choice. This limitation is given by libtiff
and not by lcms, so, it would be quite possible and probably
easy to write a program doing so on PBM or raw format.

Marti.
