推荐答案

导出为PNG或PDF将涉及转换创建PDF 或运行 imagemagick a>并返回结果.伪代码是这样的:

Exporting to PNG or PDF would involve converting the VML2SVG using the stylesheets, the VML element, and transformNode, then converting the SVG to PNG using a AJAX request which posts the image to a script which creates the PDF or runs imagemagick and returns the result. The pseudocode is something like this:

svg = vml.transformNode(vml2svg)
$.post("/svg/png-or-pdf", svg, showImg);
