### Method

# Vips Imagegifsave_buffer

#### Declaration [src]

    int
    vips_gifsave_buffer (
      VipsImage* in,
      void** buf,
      size_t* len,
      ...
    )

#### Description [src]

As `vips_gifsave()`, but save to a memory buffer.

The address of the buffer is returned in `buf`, the length of the buffer in `len`. You are responsible for freeing the buffer with `g_free()` when you are done with it.

Optional arguments

- `dither`: `gdouble`, quantisation dithering level
- `effort`: `gint`, quantisation CPU effort
- `bitdepth`: `gint`, number of bits per pixel
- `interframe_maxerror`: `gdouble`, maximum inter-frame error for transparency
- `reuse`: `gboolean`, reuse palette from input
- `interlace`: `gboolean`, write an interlaced (progressive) GIF
- `interpalette_maxerror`: `gdouble`, maximum inter-palette error for palette reusage
- `keep_duplicate_frames`: `gboolean`, keep duplicate frames in the output instead of combining them
