public Bytes save_to_tiff_bytes ()
Store the given this in memory as a TIFF file.
Use [ctor@Gdk.Texture.new_from_bytes] to read it back.
This function is intended to store a representation of the texture's data that is as accurate as possible. This is particularly relevant when working with high dynamic range images and floating-point texture data.
If that is not your concern and you are interested in a smaller size and a more portable format, you might want to use [ method@Gdk.Texture.save_to_png_bytes].
