gtk-encode-symbolic-svg - Symbolic icon conversion utility
gtk-encode-symbolic-svg [OPTION...] PATH WIDTHxHEIGHT
gtk-encode-symbolic-svg converts symbolic svg icons into specially prepared png files. GTK+ can load and recolor these pngs, just like original svgs, but loading them is much faster. PATH is the name of a symbolic svg file, WIDTHxHEIGHT are the desired dimensions for the generated png file. To distinguish them from ordinary pngs, the generated files have the extension .symbolic.png.
-o DIRECTORY, --output DIRECTORY Write png files to DIRECTORY instead of the current working directory.
