我正在尝试根据其源 svg 文件重新编译 ttf 字形字体。
我正在使用 python 和 FontForge 并努力将 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。这是我到目前为止所尝试的(一种生成临时字体并随后刮取
SplineSet 数据的低效、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')
最佳答案
使用来自 FontForge GitHub 项目的 svg2sfd.py。
归档文件:
A simple script to convert svg files (generated by Illustrator plugin) to sfd, from which Fontforge can then create a font file.
