  • tile_height: %gint for tile size
  • pyramid: %gboolean, write an image pyramid
  • bitdepth: %int, set write bit depth to 1, 2, 4 or 8
  • miniswhite: %gboolean, write 1-bit images as MINISWHITE

As vips_tiffsave(), 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.
