Images are currently generated as fast as possible, but in some

level (sic) of the graphs. It takes a nonnegative integer as its argument.
This setting has currently only a meaning for PNG images, where it is
used as the zlib compression level (i.e. 0 for no compression to 9 for
best compression). We can also imagine to use greater values to switch
between PNG compression methods (e.g 27 for the method 2 and compression
7). The default value has been kept to 1, like the current behaviour.
Specifying this setting has no incidence on all the other formats (it is
