[Bug 307314] New: Digikam uses AHD when set to AMaZE, AFD etc.

[S. Burmeister]

https://bugs.kde.org/show_bug.cgi?id=307314

            Bug ID: 307314
          Severity: normal
           Version: 3.0.0
          Priority: NOR
          Assignee: [hidden email]
           Summary: Digikam uses AHD when set to AMaZE, AFD etc.
    Classification: Unclassified
                OS: Linux
          Reporter: [hidden email]
          Hardware: Other
            Status: UNCONFIRMED
         Component: libkdcraw
           Product: digikam

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

--- Comment #1 from Gilles Caulier <[hidden email]> ---
Not reproducible. Settings is show through this trace :

-- RAW DECODING SETTINGS --------------------------------
-- autoBrightness:          true
-- sixteenBitsImage:        true
-- brightness:              1
-- RAWQuality:              9

---------------------------------------------------------

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...
