Class XSLFImageRenderer
java.lang.Object
org.apache.poi.xslf.usermodel.XSLFImageRenderer
@Beta
public class XSLFImageRenderer
- extends java.lang.Object
For now this class renders only images supported by the javax.imageio.ImageIO
framework. Subclasses can override this class to support other formats, for
example, Use Apache batik to render WMF:
public class MyImageRendener extends XSLFImageRendener{
public boolean drawImage(Graphics2D graphics, XSLFPictureData data, Rectangle2D anchor){
boolean ok = super.drawImage(graphics, data, anchor);
if(!ok){
// see what type of image we are
String contentType = data.getPackagePart().getContentType();
if(contentType.equals("image/wmf")){
// use Apache Batik to handle WMF
// see http://xmlgraphics.apache.org/batik/
}
}
return ok;
}
}
and then pass this class to your instance of java.awt.Graphics2D:
graphics.setRenderingHint(XSLFRenderingHint.IMAGE_RENDERER, new MyImageRendener());
