[b]在前端通过HighCharts获取svgCode，再根据svgCode生成图片。生成的图片在插入到word文档中 freemarker, BASE64Encoder[/b]

[b]1. 获取svgCode[/b]
var chart = $("#container").highcharts();
var svgCode = chart.getSVG();
[b]2. 根据svgCode生成图片[/b]
String svgImgPath = uploadFilePathService.getUploadFilePath()+"svg/"+salivaBox.getBarCode()+"_"+m+".png";
String svgCode = svgCodeList.get(m).replace("Highcharts.com.cn","");
SvgPngConverter.convertToPng(svgCode, svgImgPath);
params.put("image"+(m+1), SvgPngConverter.getImageBASE64Encoder(svgImgPath));
[b]3. SvgPngConverter[/b]
