It looks blocky, like it needs aliasing or som= ething. Could I improve this with some setting changes? I see some variable= s like Doc View Ghostscript Options but I don't know what options I need to= pass in. I see some discussions about this on the Internet but they are ve= ry old discussions with unclear guidance.
