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

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

Hi,

I will try to add such filter on next revision. At least it
has come to the wish list :-)

Glad to know it worked fine to you. Humm... 6 minutes is
a lot of time, even for such big image. Have you tried
latest 1.08 version? It has device link precalculation by
default and should be a bit faster. The lcms-1.08.tar.gz
package does include tifficc. It is not build by default,
but is as easy as 'make tificc' to generate the binary.

Regards,
Marti

Hy,


thank you for the fast answer!
But I'm not a good C-programmer. Is there anybody out here, who=20
can do that job for me, assumed it's realy takes just a little=20
time.=20
Otherwise I have to chose the temp-file way. I have made i test=20
with a A3-File. It takes about 6 minutes of precomputing (gs,=20
tifficc) before it starts to print. But the results are very
good=20
;)
