I am working in html to pdf conversion using flying saucer(itextrenderer)...I have to render image..I have rendered the image which was in my local storage(it works fine)..I have to do the same thing with external image..
Here is my code snippet for html to pdf image renderer...
{
try {
String url = new File(inputHtmlPath).toURI().toURL().toString();
System.out.println("URL: " + url);
OutputStream out = new FileOutputStream(outputPdfPath);
File signUpTemplate = new File("C:/Users/SFLTP022/Desktop/task/index1.html");
String content=FileUtils.readFileToString(signUpTemplate);
//Flying Saucer part
ITextRenderer renderer = new ITextRenderer();
renderer.getSharedContext().setReplacedElementFactory(new MediaReplacedElementFactory(renderer.getSharedContext().getReplacedElementFactory()));
renderer.setDocumentFromString(content.toString());
renderer.layout();
final ByteArrayOutputStream baos = new ByteArrayOutputStream();
renderer.createPDF(baos);
//ITextRenderer renderer = new ITextRenderer();
renderer.setDocument(url);
renderer.layout();
renderer.createPDF(out);
out.close();
}
Here is my default class to render html image,in which i have to load external image

}

}
return new ITextImageElement(fsImage);
}
} catch (Exception e) {
throw new RuntimeException("There was a problem trying to read a template embedded graphic.", e);
} finally {

}
}
return this.superFactory.createReplacedElement(layoutContext, blockBox, userAgentCallback, cssWidth, cssHeight);

}
When i tried this by loading local image it works fine,as shown below
input = new FileInputStream("C:\Users\Public\Pictures\Sample Pictures\" + element.getAttribute("data-src"));
My html part(local storage image) looks like
<div id="logo" class="media" data-src="Desert.jpg" style="width: 177px; height: 60px" />
My html part(External storage image) looks like
<div id="logo" class="media" data-src="base.png" style="width: 177px; height: 60px" />
The error message is
java.lang.RuntimeException: There was a problem trying to read a template embedded graphic.
