6、模糊问题，使用quality，zoom解决

import imgkit
path_wkimg = r'D:\app\wkhtmltopdf\bin\wkhtmltoimage.exe'  # 工具路径
cfg = imgkit.config(wkhtmltoimage=path_wkimg)
# # 1、将html文件转为图片
# A4纸张大小
options = {
    'encoding': 'utf8',   # 乱码
    'width': 599,
    'enable-local-file-access': '',  # 允许访问本地文件
    'quality': 100,     # 提高分辨率,100最高
    'zoom': 4       # 增加缩放比例
}
imgkit.from_file(r'temp.html', 'helloworld.jpg', config=cfg, options=options)
