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

Description [src]

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: %boolean, keep duplicate frames in the output instead of combining them

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.
