+ * gdk_texture_save_to_tiff_bytes:
+ * @texture: a `GdkTexture`
+ *
+ * Store the given @texture in memory as a TIFF file.
+ * Use 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 gdk_texture_save_to_png_bytes().
+ *
+ * Returns: a newly allocated `GBytes` containing TIFF data
+ *
+ * Since: 4.6
