svg转成png
//svg转为png
public static void convertSvg2Png(File svg, File png) throws IOException,TranscoderException
{
InputStream in = new FileInputStream(svg);
OutputStream out = new FileOutputStream(png);
out = new BufferedOutputStream(out);
Transcoder transcoder = new PNGTranscoder();
try {
TranscoderInput input = new TranscoderInput(in);
try {
TranscoderOutput output = new TranscoderOutput(out);
transcoder.transcode(input, output);
} finally {
out.close();
}
} finally {

}
}
public static void main(String args[]){
File f=new File("E:/Pinterest_pinterest30.svg");
File destFile=new File("E:/Pinterest_pinterest30.png");
try {
convertSvg2Png(f, destFile);
} catch (IOException e) {

这里我们也可以通过svg字符串转成图片。
