Image not showing in PDF [message #789912]

Hello, I am using a script to add an image to a report via URL. It works correctly in preview mode and it works in the web viewer. However, when I click "Export PDF" or any other format(doc,ppt, etc...) the image does not render.

My script in my .rptdesign file is

beforeFactory

importPackage(Packages.javax.imageio);
importPackage(Packages.java.io);
importPackage(Packages.java.net);
importPackage(Packages.java.lang);
importPackage(Packages.org.apache.commons.codec.binary)
importPackage(Packages.java.lang);

var myurl = URL("http://tomcat.apache.org/images/tomcat.gif");
var img = ImageIO.read(myurl);
bas = new ByteArrayOutputStream();
ImageIO.write(img, "jpg", bas);
bas.flush();

encodedimga = Base64.encodeBase64(bas.toByteArray());
encodedimg = new String( encodedimga, "utf-8"); 
bas.close();
imgsrc = "data:image/jpg;base64,"+encodedimg+"\"";

I have a html text element with a value of

<img src=<VALUE-OF>imgsrc</VALUE-OF> +" alt="what ever" />

Again this only renders in the web viewer not as any other format.

I am using web viewer 3.7

Thank you for any help you can provide.

Set the image as dynamic image and then on the onRender script of the image itself write some code as the following :

importPackage(Packages.java.io);
importPackage(Packages.java.lang);
importPackage(Packages.java.net);
importPackage(Packages.javax.imageio);



//Image at url
var myurl = new Packages.java.net.URL("http://tomcat.apache.org/images/tomcat.gif");

var img = ImageIO.read(myurl);
var bas = new ByteArrayOutputStream();
ImageIO.write(img, "gif", bas);
this.data = bas.toByteArray();
}
