我正在使用iText和一些SVG渲染库。
我想将SVG图像渲染为PDF。我使用以下代码来做到这一点。现在问题是我给它一个面积图SVG,它没有正确渲染线。附上截图。
已使用以下课程:
import org.apache.batik.bridge.BridgeContext;
import org.apache.batik.bridge.DocumentLoader;
import org.apache.batik.bridge.GVTBuilder;
import org.apache.batik.bridge.UserAgent;
import org.apache.batik.bridge.UserAgentAdapter;
import org.apache.batik.dom.svg.SAXSVGDocumentFactory;
import org.apache.batik.gvt.GraphicsNode;
import org.apache.batik.util.XMLResourceDescriptor;
import org.w3c.dom.svg.SVGDocument;
这里是警察片段:
String parser = XMLResourceDescriptor.getXMLParserClassName();
factory = new SAXSVGDocumentFactory(parser);
UserAgent userAgent = new UserAgentAdapter();
DocumentLoader loader = new DocumentLoader(userAgent);
ctx = new BridgeContext(userAgent, loader);
ctx.setDynamicState(BridgeContext.DYNAMIC);
builder = new GVTBuilder();
PdfContentByte cb = writer.getDirectContent();
PdfTemplate chartImageTemplate = cb.createTemplate(1000, 1000);
SVGDocument svgDoc=null;
try {
InputStream in = new ByteArrayInputStream(chartImage.getBytes());
svgDoc = factory.createSVGDocument("", in);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try{
GraphicsNode mapGraphics = builder.build(ctx, svgDoc);
DefaultFontMapper mapper = new DefaultFontMapper();
PdfGraphics2D g2 = (PdfGraphics2D)cb.createGraphics(1000, 500, mapper);
Graphics2D g2d = g2;
mapGraphics.paint(g2d);
g2d.dispose();
cb.addTemplate(chartImageTemplate, 0, 0);
return mapGraphics.getGeometryBounds().getHeight();
}catch(Exception e){
}
