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

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.

• compression: VipsForeignTiffCompression, write with this compression
• Q: gint, quality factor
• predictor: VipsForeignTiffPredictor, use this predictor
• tile: gboolean, set TRUE to write a tiled tiff
• tile_width: gint, for tile size
• tile_height: gint, for tile size
• pyramid: gboolean, write an image pyramid
• bitdepth: gint, change bit depth to 1,2, or 4 bit
• miniswhite: gboolean, write 1-bit images as MINISWHITE
• resunit: VipsForeignTiffResunit for resolution unit
• xres: gdouble, horizontal resolution in pixels/mm
• yres: gdouble, vertical resolution in pixels/mm
• bigtiff: gboolean, write a BigTiff file
• properties: gboolean, set TRUE to write an IMAGEDESCRIPTION tag
• region_shrink: VipsRegionShrink How to shrink each 2x2 region.
