Commands used to generate the images in opentype-shaping-gurmukhi.md

Arrow general

hb-view --font-size=110 --output-file=right-arrow.png --background=FFFFFF00 --margin=0,0,0,0 /usr/share/fonts/opentype/gentiumplus/GentiumPlus-R.ttf --unicodes=2192

Note: always use --features=-init in examples where the init feature itself is not being explained.

Note: There is, at present, no Noto Serif for Gurmukhi; therefore (unlike the other Indic scripts) these examples use Noto Sans. Serif would be preferrable if it appears in the future, though, due to the increased stroke contrast.
