Demosaicing doesn't use certain methods

[Remco Viëtor]

Hi,

looking for something else, I noticed that Digikam versions 3.5 and 4.1
(both the one from OpenSuse 13.1 and a local build) don't use several of
the demosaicing options: AmaZe, LMMSE, VCD.

This might be a problem with my version of libraw or libkdcraw, but in any
case, it would be nice to get a warning when certain methods aren't
available.

regards,

Remco

Methods are typically disabled in GUI. These methods are relevant of
libraw extra packs. If packs are not compiled with libraw, these
methods are not available and disabled...

That's just it: none of the methods are disabled in the RAW import tab, but
when running Digikam from the command line, I see lines like

"AHD interpolation..."
"Median filter pass 1..."

even when I have selected a method mike AFD, LMMSE, AmaZE. Also the
behaviour in the progress bar stays the same as for teh AHD settings
(notably visible when changing the number of median passes for AHD).

And like I said, I did a local build for both DigiKam 3.5 and 4.1, and I
see the same behaviour as for the distribution builds.

(I stopped using 4.1/4.2 for now due to other issues with it, notably
related to the scaling misbehaving in several tools).

Go to Help/components info dialog. What libraw pack status said ?

LibRaw 0.15.3, nothing more.

The library file (libraw.so.9.0.0) shows the following symbols:
_ZN6LibRaw15lin_interpolateEv
_ZN6LibRaw15vng_interpolateEv
_ZN6LibRaw15ppg_interpolateEv
_ZN6LibRaw15ahd_interpolateEv
_ZN6LibRaw19ahd_interpolate_modEv
_ZN6LibRaw18afd_interpolate_plEii
_ZN6LibRaw15vcd_interpolateEi
_ZN6LibRaw17lmmse_interpolateEi
_ZN6LibRaw16es_median_filterEv
_ZN6LibRaw17amaze_demosaic_RTEv

(internal references to the different demosaicing routines, I guess)

Worst is in Refocus tool, in which I set magnification to 100%. There,
preview 'after' didn't even show the same area of the image as the 'before'
view...

In general, all tools start up with a magnification of 16%, where the
'normal' view (scaled to available space) is 37 % for landscape images (and
this is what the main window was set to, and at which I left the tools on
exit).
Resizing to full view size seems to work (I didn't test the other tools
with different magnifications).

No problem here to run LC tool in 100%. rendering region is right as
