Vips.Image.gaussblur

### Method

# Vips Imagegaussblur

#### Declaration [src]

    int
    vips_gaussblur (
      VipsImage* in,
      VipsImage** out,
      double sigma,
      ...
    )

#### Description [src]

This operator runs `vips_gaussmat()` and `vips_convsep()` for you on an image.

Set `min_ampl` smaller to generate a larger, more accurate mask. Set `sigma` larger to make the blur more blurry.

Optional arguments

- `precision`: `VipsPrecision`, precision for blur, default int
- `min_ampl`: `gdouble`, minimum amplitude, default 0.2
