Description S. Burmeister 2012-09-24 08:52:57 UTC

If one sets the raw import utility in the editor to use bilinear digikam's debug output shows that it uses bilinear. If one sets it to AMaZE or e.g. AFD it shows:

AHD interpolation...

Should this not be AMaZE, AFD etc.?

Reproducible: Always

Not reproducible. Settings is show through this trace :

Where " -- RAWQuality:              9" here mean LMMSE, in this example. Changing quality in GUI, change RAW settings passed to LibRaw accordingly.

The message "AHD interpolation..." printed after settings trace come from LibRaw, not digiKam. I think it's a generic printf to indicate which action is done, not which interpolation method is used exactly. As you can see in source code :

https://projects.kde.org/projects/kde/kdegraphics/libs/libkdcraw/repository/revisions/master/entry/libraw/internal/dcraw_common.cpp#L4114

...printed message is hardcoded...
