推荐答案

我不熟悉w / wkhtmltopdf，但我确实使用wkhtmltoimage来创建包含来自高图的图表的页面图像。我注意到的一件事是我必须将--javascript-delay设置为几秒钟，以确保图表有足够的时间加载。似乎wkhtmltopdf确实支持这个选项（）。你可以看到这是否有帮助？

I am not familiar w/wkhtmltopdf but I do use wkhtmltoimage to create images of pages that contain graphs from highcharts. One thing I noticed is that I had to set --javascript-delay to be several seconds long to make sure the chart had enough time to load. It seems as though wkhtmltopdf does support this option (wkhtmltopdf v0.10.0_rc2 docs). Can you see if that helps?

以下是我们如何将它称为w / javascript延迟3秒：

Here is how we call it w/a javascript delay of 3 seconds:

/bin/wkhtmltoimage --javascript-delay 3000 "http://example.com/chartPage" "/path/to/image.png"
