" -mip_linear: Keep image in linear light during mipmap filtering\n"
" -mip_linear: Keep image in linear light during mipmap filtering (i.e. do not convert to/from sRGB for filtering purposes)\n"
" -mip_scale X: Set mipmap filter kernel's scale, lower=sharper, higher=more blurry, default is 1.0\n"
" -mip_filter X: Set mipmap filter kernel, default is kaiser, filters: box, tent, bell, blackman, catmullrom, mitchell, etc.\n"
" -mip_renorm: Renormalize normal map to unit length vectors after filtering\n"
" -mip_clamp: Use clamp addressing on borders, instead of wrapping\n"
" -mip_smallest X: Set smallest pixel dimension for generated mipmaps, default is 1 pixel\n"
"By default, mipmap filtering will occur in sRGB space (for the RGB color channels) unless -linear is specified. You can override this behavior with -mip_srgb/-mip_linear.\n"
