Hi All,
when using wavelet decomposition in Gimp 2.10 I noted the frequency layer is blended as “legacy” and not as “default” as other layers.
Can someone explain me because if I switch to default mode there is a very little difference with the original image??
Thanks
Its because 2.10 changed all the layer blending around; the wavelet script has not been updated accordingly. Someone should update it!
Hi paperdigits,
could be the scripts is outdatated but if I make the manual procedure (duplicate the layer;blur it;make it as grain extract mode;make a new layer from visible and make it as grain merge mode;switch the blurred layer as normal mode) and set the higher frequency layer as legacy the result pixel of blurred+higher frequency layer is the same as original layer; if a set it as default there is a little difference. 
By little difference, do you mean if you use default mode, nothing happens? Or do you mean default mode gives the same results as the legacy mode?
G’MIC has a Split Details [Wavelets] filter that you might like.
There is also a native “Wavelet Decompose” function available using GEGL. Its probably a better option to use. (I’m not near my computer right now to actually find it in the menus, but take a look!)
Enhance > Wavelet-decompose...
That is the one with legacy blends.
Hit the / key and type wavelet. No more digging through the menus in >=2.10
Hi afre,
what I mean is when I use wavelet-decompose filter it creates the grain merge layer as legacy mode.
In this way if I put a sample point it has the same value on base layer and on sum of splitted layers.
If I change the grain-merge as default the sample point is different.
Hi, trying on some images I found the new grain-merge layer is created legacy or default by something I do not know.
with foglia.tif (37.0 MB) I have legacy mode
with _DSC9196.tif (57.4 MB) I have default mode
If a change the mode proposed the sample point changes.
Therefore my question is: Which is the variable which do a grain-merge as legacy or as default??
I’m confused
