i doubt you need to steal these two lines of code. probably faster to type your own version than to copy/paste + fixup… :

darktable-org/darktable/blob/master/src/develop/pixelpipe_hb.c#L995


      
          
            const dt_iop_order_iccprofile_info_t *const profile =
              dt_ioppr_get_pipe_current_profile_info(module, piece->pipe);
          
            dt_color_picker_helper(dsc, pixel, &roi_copy, box,
                                   darktable.lib->proxy.colorpicker.primary_sample->denoise,
                                   pick, image_cst,
                                   dt_iop_color_picker_get_active_cst(module), profile);
          
            for_four_channels(k)
            {
              picked_color_min[k] = pick[DT_PICK_MIN][k];
              picked_color_max[k] = pick[DT_PICK_MAX][k];
              picked_color[k] = pick[DT_PICK_MEAN][k];
            }
          
          error:
            dt_free_align(tmpbuf);
          }
          #endif
