batik1.8相对于1.7的改进

              以前写的java程序用的batik1.7。后来1.8出来了并没有发现什么不同，就一直用1.7了。今天偶然间需要做个图表。使用d3生成了一个柱状图，柱状图的代码如下

<svg contentScriptType="text/ecmascript" width="300.0" xmlns:xlink="http://www.w3.org/1999/xlink" zoomAndPan="magnify" style="background-color:#ffffff;" contentStyleType="text/css" viewBox="0 0 300.0 200.0" height="200.0" preserveAspectRatio="xMidYMid meet" xmlns="http://www.w3.org/2000/svg" version="1.0">
<style>
.axis text {

.axis path,
.axis line {

.bar {

fill-opacity: .9;
}

.x.axis path {

}

可以看到在此文件中应用了style属性。结果用自己的app打开如下图



比较难看，而实际在浏览器下打开如下



发现在自己的app下style并没有生效。试一试的想法替换了batik版本，发现居然一致了。所以估计是batik1.8把这块bug修正了
