逆向10-懂车帝字体
懂车帝二手车
1. python获取请求和响应

2. 脚本-字体woff做映射表
3. 懂车帝-实例
有两个文件一个是主文件（dcd.py），一个是第二步的映射表文件(util.py)
from fontTools.ttLib import TTFont
import ddddocr
from io import BytesIO
from PIL import Image, ImageDraw, ImageFont
def convert_cmap_to_image(cmap_code, font_path):
img_size = 1024
img = Image.new("1", (img_size, img_size), 255) # 创建一个黑白图像对象
draw = ImageDraw.Draw(img) # 创建图对象
font = ImageFont.truetype(font_path, int(img_size) * 0.6) # 加载字体文件
character = chr(cmap_code) # 将 cmap code转换为字符
bbox = draw.textbbox((0, 0), character, font=font) # 获取文本在图像中的边界框，bbox获取的是四个值
width = bbox[2] - bbox[0] # 文本宽度
height = bbox[3] - bbox[1] # 文本高度
draw.text(((img_size - width) // 2, (img_size - height) // 7), character, font=font) # 绘制文本，并中显示
return img
def extract_text_from_font(font_path):
font = TTFont(font_path) # 加载字体文件
# font.saveXML("font.xml") # 保存XML文件(可以这么操作，但是这里我们不用)
ocr = ddddocr.DdddOcr(beta=True, show_ad=False) # 实例化
font_map = {}
for cmap_code, glyph in font['cmap'].getBestCmap().items():
#
image = convert_cmap_to_image(cmap_code, font_path)
bytes_io = BytesIO()
image.save(bytes_io, format='PNG')
# 识别图像
text = ocr.classification(bytes_io.getvalue())
# 生成对应名字的图片
# image.save(f'./images/{text}.png', format='PNG')
# 最后生成映射表----根据每个案例 适当修改
font_map[hex(cmap_code).replace("0x", "")] = text
return font_map
