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. I am running GNU Emacs 30.0.91 (build 10, x86_64-pc-linux-gnu, GTK+ Version= 3.24.41, cairo version 1.18.0) of 2024-10-04. --=20 =F0=9F=93=9B Christopher Howard =F0=9F=9A=80 gemini://gem.librehacker.com =F0=9F=8C=90 http://gem.librehacker.com =D7=91=D7=A8=D7=90=D7=A9=D7=99=D7=AA =D7=91=D7=A8=D7=90 =D7=90=D7=9C=D7=94= =D7=99=D7=9D =D7=90=D7=AA =D7=94=D7=A9=D7=9E=D7=99=D7=9D =D7=95=D7=90=D7=AA= =D7=94=D7=90=D7=A8=D7=A5
