# genflags.sh - Generates pngs for use with CountryDropdown.js
|
|
#
|
|
# Dependencies:
|
|
# - imagemagick --with-rsvg (because default imagemagick SVG
|
|
# renderer does not produce accurate results)
|
|
#
|
|
# on macOS, this is most easily done with:
|
|
# brew install imagemagick --with-librsvg
|
|
#
|
|
# This will clone the googlei18n flag repo before converting
|
|
# all phonenumber.js-supported country flags (as SVGs) into
|
|
# PNGs that can be used by CountryDropdown.js.
