Font_Tools的使用
1、fontTools使用总结
from fontTools.ttLib import TTFont
# 加载字体文件：
font = TTFont('local_fonts.woff')
# 保存为xml文件：
font.saveXML('local_fonts.xml')
# 获取各节点名称，返回为列表
print(font.keys()) # ['GlyphOrder', 'head', 'hhea', 'maxp', 'OS/2', 'hmtx', 'cmap', 'loca', 'glyf', 'name', 'post', 'GSUB']
# 获取getGlyphOrder节点的name值，返回为列表
print(font.getGlyphOrder()) # ['glyph00000', 'x', 'uniF013', 'uniF4D4', 'uniEE40', 'uniF7E1', 'uniF34B', 'uniE1A0', 'uniF1BE', 'uniE91E', 'uniF16F', 'uniF724']

# 获取glyf节点TTGlyph字体xMin,yMin,xMax,yMax坐标信息
print(font['glyf']['uniE1A0'].xMin, font['glyf']['uniE1A0'].yMin,
font['glyf']['uniE1A0'].xMax, font['glyf']['uniE1A0'].yMax) # 0 -49 521 711
# 获取glyf节点TTGlyph字体on信息
print(font['glyf']['uniE1A0'].flags) # array('B', [1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 0, 1, 0, 0, 1, 0, 1, 0, 1, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0])
# 获取GlyphOrder节点GlyphID的id信息, 返回int型
print(font.getGlyphID('uniE1A0')) # 7
2、加载字体文件
font = TTFont('local_fonts.woff')
3、保存为xml文件：
font.saveXML('local_fonts.xml')
4、获取各节点名称，返回为列表：
font.keys()
# ['GlyphOrder', 'head', 'hhea', 'maxp', 'OS/2', 'hmtx', 'cmap', 'loca', 'glyf', 'name', 'post', 'GSUB']
5、获取getGlyphOrder节点的name值，返回为列表：

# 0 -49 521 711
9、获取glyf节点TTGlyph字体on信息（0表示弧形/1表示矩形）：
font['glyf']['uniE1A0'].flags
# array('B', [1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 0, 1, 0, 0, 1, 0, 1, 0, 1, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0])
10、 获取GlyphOrder节点GlyphID的id信息, 返回int型：
font.getGlyphID('uniE1A0')
# 7
11、 将woff2文件转成ttf文件并解析：
from fontTools.ttLib import TTFont
from fontTools.ttLib.woff2 import decompress
woff2_path = "./woff/704224.woff2"
ttf_path = './woff/704224.ttf'
xml_path = './woff/704224.xml'
decompress(woff2_path, ttf_path) # 将woff2文件转成ttf文件
font = TTFont(ttf_path)
font.saveXML(xml_path)
12、 识别woff.2/ttf/woff的字体结果
from PIL import ImageFont, Image, ImageDraw
from io import BytesIO
import ddddocr
from fontTools.ttLib import TTFont
from fontTools.ttLib.woff2 import decompress
# woff2_path = "./woff/704224.woff2"
# ttf_path = './woff/704224.ttf'
# xml_path = './woff/704224.xml'
# decompress(woff2_path, ttf_path) # 将woff2文件转成ttf文件
# _font = TTFont(ttf_path)
# _font.saveXML(xml_path)
def font_to_img(_code, filename):
"""将字体画成图片"""
img_size = 1024
img = Image.new('1', (img_size, img_size), 255)
draw = ImageDraw.Draw(img)
font = ImageFont.truetype(filename, int(img_size * 0.7))
txt = chr(_code)
x, y = draw.textsize(txt, font=font)
draw.text(((img_size - x) // 2, (img_size - y) // 2), txt, font=font, fill=0)
return img
def identify_word(_ttf_path):
"""识别ttf字体结果"""
font = TTFont(_ttf_path)
ocr = ddddocr.DdddOcr()
for cmap_code, glyph_name in font.getBestCmap().items():
bytes_io = BytesIO()
pil = font_to_img(cmap_code, _ttf_path)
pil.save(bytes_io, format="PNG")
word = ocr.classification(bytes_io.getvalue()) # 识别字体
print(cmap_code, glyph_name, word)
# with open(f"./img/{cmap_code}_{glyph_name}.png", "wb") as f:
# f.write(bytes_io.getvalue())
13、 乱码字母数字转成图片
from PIL import ImageFont, Image, ImageDraw
from io import BytesIO
import ddddocr
from fontTools.ttLib import TTFont
def luan_word_to_img(text, _ttf_path, img_path='./word.png'):
"""将字体画成图片"""
img_size = 1024
img = Image.new('1', (img_size, img_size), 255)
draw = ImageDraw.Draw(img)
word_size = int(img_size * (1 / len(text)))
font = ImageFont.truetype(_ttf_path, word_size)
x, y = draw.textsize(text, font=font)
draw.text(((img_size - x) // 2, (img_size - y) // 2), text, font=font, fill=0)
# img.show()
# img.save(img_path)
bytes_io = BytesIO()
img.save(bytes_io, format="PNG")
word = ocr.classification(bytes_io.getvalue()) # 识别字体
# print(text, word)
return [text, word]
ocr = ddddocr.DdddOcr()
luan_word_to_img('┋', './woff/599427.ttf')
luan_word_to_img('㑁', './woff/7SourceHanSansCN-Normal-2500.ttf')
luan_word_to_img('㖉㒍', './woff/7SourceHanSansCN-Normal-2500.ttf')
14、网页上的乱码字和ttf的camp_code的转换
-
乱码字= chr(cmap_code) ; ord(乱码字）=cmap_codefrom fontTools.ttLib import TTFont
ttf_path = './woff/704224.ttf'
_font = TTFont(ttf_path)
for cmap_code, glyph_name in _font.getBestCmap().items():
# print(glyph_name.replace("uni", r"\u").encode('utf-8').decode('unicode_escape'))
print(f"cmap_code:{cmap_code}, chr(cmap_code):{chr(cmap_code)}, glyph_name: {glyph_name}")
