Re: [Gimp-developer] USM update

Sorry, that should be "a new git clone" and not "a new git pull".

Hi Elle,

Not a problem. It's possible the issue is related to gaussian-blur.
However, I did try to revert back the latest changes to the unsharp-mask.c
from 2 weeks ago and still got the Windows equivalent of segfault. So, I
decided to completely start afresh with the a new git pull of babl, gegl
and gimp.

I am still getting crashes. The crash is probably related to GSlice:

I can post the full error set if anyone wishes.

I was not experiencing any crashes with unsharp mask then.

This is the version from before Elle changed it:

 Thanks again,


Tobias, Partha, my apologies, it was late and I turned my computer off.

I also substituted "Gaussian Blur" for USM in my mind, totally different
things (there's a blur in USM, but that's beside the point).

Anyway, anyone have any ideas why a change in the ui slider values might
cause a crash in Windows USM? Could it be because the minimum for the top
slider is 0.2 instead of 0.0?

gegl_chant_double_ui (std_dev, _("Std. Dev."),
                      0.2, 300.0, 0.55, 0.2, 10.0, 3.0,
                      _("Standard deviation (spatial scale factor)"))

gegl_chant_double_ui (scale, _("Scale"),
                      0.0, 300.0, 4.0, 0.0, 10.0, 3.0,
                      _("Scale, strength of effect"))

Elle, feeling very foolish for having mixed up GB and USM.
