将.html文件转换为图像

Question

我正在寻找能够忠实地将.html文件转换为图像格式的任何实用程序 - 首选png或jpeg.我用Google搜索了几个小时并下载了十几个免费试用版,但似乎没有任何工作.Adobe Acrobat Pro几乎可以使用,但它决定缩小表格单元以适应页面,而不是缩小整个表格.

任何建议表示赞赏.

问候.

Answer 1

我正在使用wkhtmltoimage.

它是一个快速的命令行工具,它使用webkit库来呈现任何网站.有两个版本用于生成pdfs,另一个用于生成图像.

wkhtmltoimage适用于Windows,Linux和Mac.
