icon-octicons
Octicons as 774 pre-rendered CrImage constants for Crystal. Icons retain their source dimensions, including non-square logos.
dependencies:
icon-octicons:
github: kojix2/icon-octicons
require "icon-octicons"
icon = Icon::Octicons::Heart16
Names follow the SVG filenames. Use require "icon-octicons/16" to load only one size. PNG data lives in src/data/*.tsv and is loaded by a Crystal macro. Constants are shared, mutable images; copy before editing.
