使大的 HTML 文件更小而不损失质量。删除不必要和未使用的数据。在代码中缩小 HTML 文件的大小。 Python 库为开发人员提供了一个集成的 API 来优化 HTML 内容。
Python 库是一个独立的解决方案，不需要安装任何第三方软件。
使用 'Aspose.Words for Python via .NET' 可以轻松实现无损压缩和深度内容优化。以下示例演示了如何优化 Python 中的 Python HTML 文件的内容：
pip install aspose-words
import aspose.words as aw
doc = aw.Document("Input.html")
doc.cleanup()
shapes = [node.as_shape() for node in doc.get_child_nodes(aw.NodeType.SHAPE, True)]
for shape in shapes:
if shape.isImage:
# 由开发者选择用于图像压缩的库。
image = Image.open(shape.image_data.to_stream())
# ...
# 压缩图像并将其设置回形状。
shape.image_data.set_image("yourCompressedImage")
doc.save("Output.html")
import aspose.words as aw
doc = aw.Document("Input.html")
doc.cleanup()
shapes = [node.as_shape() for node in doc.get_child_nodes(aw.NodeType.SHAPE, True)]
for shape in shapes:
if shape.isImage:
# 由开发者选择用于图像压缩的库。
image = Image.open(shape.image_data.to_stream())
# ...
# 压缩图像并将其设置回形状。
shape.image_data.set_image("yourCompressedImage")
save_options = aw.saving.PdfSaveOptions
save_options.cache_background_graphics = true
doc.save("Output.html", save_options)
import aspose.words as aw
doc = aw.Document("Input.html")
doc.cleanup()

set_page_size(page_setup, max_page_dimension, max_page_dimension)
