Yes, it's right.
implement your UriResolver, set the fopFactory and debug your programme.
You will see that you pass in your resolve(String href, String base) method
when fop search your image. in href you'll see your image file name and so
you can plugged your real image with the inputStream resolve method return.
So you can put your image in the classpath and use as :
resolve(String href, String base) {
return YourUriResolver.class.getResourceAsStream(href);
}
or :
public class SimpleUriResolver implements URIResolver {
/**
* Instantiates a new fop uri resolver.
*/
public SimpleUriResolver() {
super();
}
/*
* (non-Javadoc)
* @see javax.xml.transform.URIResolver#resolve(java.lang.String,
java.lang.String)
*/
public Source resolve(String href, String base) throws
TransformerException {
Source src;
final String file = "file:";
if (href.startsWith(file)) {
src = new StreamSource(new File(href.substring(file.length())));
} else {
src = new
StreamSource(SimpleUriResolver.class.getResourceAsStream(href));
}
return src;
}
}
As you want :)
