[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]
