/**
* vips_dzsave:
* @in: image to save
* @dirname: directory to save to
* @...: %NULL-terminated list of optional named arguments
*
* Optional arguments:
*
* @suffix: suffix for tile tiles (default ".jpg")
* @overlap; set tile overlap
* @tile_width; set tile size
* @tile_height; set tile size
*
* Save an image to a deep zoom - style directory tree.
*
* The image is shrunk in a series of x2 reductions until it fits within a
* tile. Each layer is written out to a separate subdirectory of @dirname,
* with directory "0" holding the smallest, single tile image.
*
* Each tile is written as a separate file named as "@x_@y@suffix", where @x
* and @y are the tile coordinates, with (0, 0) as the top-left tile.
*
* You can set @suffix to something like ".jpg[Q=85]" to set the tile write
* options.
*
* See also: vips_tiffsave().
*
* Returns: 0 on success, -1 on error.
