三种利用python将html文件转图片的方式

工作需要将pyecharts的表格组件Ta ble 生成的html 文件转图片，尝试了三种方式，只有第三种方式成功了

snap shot–p h antom js 是 pyecharts + ph antom js 渲染图片的扩展，支持 pngjpe gg ifpdf svg等格式

from pyecharts import options as opts
from pyecharts.charts import Table
from pyecharts.render import make_snapshot
from snapshot_phantomjs import snapshot

from pyecharts.options import ComponentTitleOpts


table = Table()

headers = ["City name", "Area", "Population", "Annual Rainfall"]
rows = [
    ["Brisbane", 5905, 1857594, 1146.4],
    ["Adelaide", 1295, 1158259, 600.5],
    ["Darwin", 112, 120900, 1714.7],
    ["Hobart", 1357, 205556, 619.5],
    ["Sydney", 2058, 4336374, 1214.8],
    ["Melbourne", 1566, 3806092, 646.9],
    ["Perth", 5386, 1554769, 869.4],
]
table.add(headers, rows)
table.set_global_opts(
    title_opts=ComponentTitleOpts(title="Table-基本示例", subtitle="我是副标题支持换行哦")
)
table.render("table_base.html")

file_path = "{}/".format(os.path.dirname(os.path.abspath("/root/echarts.min.js")))
Table(init_opts=opts.InitOpts(js_host=file_path))
make_snapshot(snapshot,table.render(),"table0.pdf")

结果仍然报错，TypeError: Table.init() got an unexpected key word ar gument ‘init_op ts’
经查找，发现snaps hot_phantomjs支持别的图导出如Bar、Grid、Line等都可以用这种方式，但是Table组件不支持

使用Aspose.Words for Python API。用python 读取和操作各种类型文档比如 Microsoft Word（DOC、DOCX、ODT）、PDF和 Web（HTML、Mar k down）文档

以jpeg为例

import aspose.words as aw
doc = aw.Document("table_base.html")
imageOptions = aw.saving.ImageSaveOptions(aw.SaveFormat.JPEG)
imageOptions.jpeg_quality = 10
imageOptions.horizontal_resolution = 72

# Save the pages as JPG
for page in range(0, doc.page_count):
extractedPage = doc.extract_pages(page, 1)
extractedPage.save(f"C:\Files\Images\Page_{page + 1}.jpg", imageOptions)

import imgkit
 
path_wkimg = r'D:Program Fileswkhtmltopdfbinwkhtmltoimage.exe'  # 工具路径
cfg = imgkit.config(wkhtmltoimage=path_wkimg)
#可以修改参数，图片大小、语言等
# options={
#     page-size:""
# }
# 将html文件转为图片
imgkit.from_file('table_base.html', 'hellotable.jpg', config=cfg)
