将 SVG 转换为 FontForge 的 SplineSet 格式
converting an SVG to FontForge's SplineSet format
我正在尝试根据源 svg 文件重新编译 ttf 字形字体。
我正在使用 python 和 FontForge，并且正在努力将 SVG 形状转换为 FontForge 的 SplineSet 格式。例如，this SVG file
以 FontForge 生成的字体表示为这种 SplineSet 格式

我想创建一个接收 SVG 并输出 SplineSet 的函数。
这是我目前为止尝试过的方法（生成临时字体然后抓取 SplineSet 数据的一种低效、幼稚的方法。顺便说一句，与真实字体相比，这是非常不准确的）
import fontforge
def main():
font = fontforge.font()
unicode_id = 57865
unicode_name = 'uni' + hex(unicode_id).upper()[2:]
char = font.createChar(unicode_id, unicode_name)
glyph = char.importOutlines('file.svg')
font.save('result.sfd')
关于如何做到这一点的任何参考？
使用来自 FontForge GitHub 项目的 svg2sfd.py。

我想创建一个接收 SVG 并输出 SplineSet 的函数。
这是我目前为止尝试过的方法（生成临时字体然后抓取 SplineSet 数据的一种低效、幼稚的方法。顺便说一句，与真实字体相比，这是非常不准确的）
import fontforge
def main():
font = fontforge.font()
unicode_id = 57865
unicode_name = 'uni' + hex(unicode_id).upper()[2:]
char = font.createChar(unicode_id, unicode_name)
glyph = char.importOutlines('file.svg')
font.save('result.sfd')
关于如何做到这一点的任何参考？
使用来自 FontForge GitHub 项目的 svg2sfd.py。
