Your code works for me.
solene@ and I tested this code and worked for us:
#lang racket
(require 2htdp/image)
(define (hello)
(text/font "Hello World 42" 24 "black"
"Luxi Sans" 'roman 'normal 'normal #f))
(save-image (hello) "test.png")
In the video, I see font rendering problems in the DrRacket REPL, which
is quite weird because the code editor and the menu work fine. So, you
have missing fonts, a broken config which renders erroneously some
glyphs or a broken lib. htdp uses the draw lib and it uses cairo. If we
had cairo/pango broken, we would see missing glyphs everywhere. Racket
doesn't use low level libs.
Try this:
- Change /etc/installurl to https://cdn.openbsd.org/pub/OpenBSD
- sysupgrade -f -s
- pkg_add -Dinstalled -Viu
- pkg_delete -a
That should reinstall everything and remove old libraries.
