+      quality (int, optional): Controls the compression-speed vs compression-
+        density tradeoff. The higher the quality, the slower the compression.
+        Range is 0 to 11. Defaults to 11.
+      lgwin (int, optional): Base 2 logarithm of the sliding window size. Range
+        is 10 to 24. Defaults to 22.
+      lgblock (int, optional): Base 2 logarithm of the maximum input block size.
