How do I install the Demosaic Packs?

Hi @ all!

I'm using LibRaw to write a simple RAW Converter with QT under Windows using Visual Studio 2010.

Now I'm trying to install the demosaic packs for libraw 0.16.2 but I am not able to do so.

I've tried to use the pre-compiled .zip File and to rebuilt them for my system using the documentation (http://www.libraw.org/docs/Install-LibRaw-eng.html used Windows: Native Building ). This was successful without any error. Then I tried to test whether the packs are installed. I found this code sample http://www.libraw.org/node/2007 but I am not quite sure if it works for me, I just get this for every demosaicing routine in the ppm file:

P5
0 0
255

When I use dcraw_process() and dcraw_ppm_tiff_writer() I cannot see any difference in the demosaicing packs GPL2 & GPL3 compared to the ahd algorithm which is used when no additional demosaic packs are installed. I know they would differ just a little bit.

Is there any other chance to test whether the packs are installed? Have I installed them right?

Thanks,
Lukas

There is no any runtime check

There is no any runtime check to check demosaic pack compiled in.

Make sure that you compile LibRaw with LIBRAW_DEMOSAIC_PACK_GPL2 and LIBRAW_DEMOSAIC_PACK_GPL3 defines.
