3.50 GraphicImage
GraphicImage extends standard JSF graphic image component with the ability of displaying binary
data like an inputstream. Main use cases of GraphicImage is to make displaying images stored in
database or on-the-fly images easier. Legacy way to do this is to come up with a Servlet that does
the streaming, GraphicImage does all the hard work without the need of a Servlet.

Getting started with GraphicImage
GraphicImage requires an org.primefaces.model.StreamedContent content as it’s value for dynamic
images. StreamedContent is an interface and PrimeFaces provides a built-in implementation called
DefaultStreamedContent. Following examples loads an image from the classpath.
<p:graphicImage value="#{imageBean.image}" />
public class ImageBean {
private StreamedContent image;
public DynamicImageController() {
InputStream stream = this.getClass().getResourceAsStream("barcalogo.jpg");
image = new DefaultStreamedContent(stream, "image/jpeg");
}
public StreamedContent getImage() {
return this.image;
}
}
DefaultStreamedContent gets an inputstream as the first parameter and mime type as the second. 
In a real life application, you can create the inputstream after reading the image from the database.
For example java.sql.ResultsSet API has the getBinaryStream() method to read blob files stored in
database.

Displaying Charts with JFreeChart
See static images section at chart component for a sample usage of graphicImage with jFreeChart.
Displaying a Barcode
Similar to the chart example, a barcode can be generated as well. This sample uses barbecue project
for the barcode API.
<p:graphicImage value="#{backingBean.barcode}" />
public class BarcodeBean {
private StreamedContent barcode;
public BackingBean() {
try {
File barcodeFile = new File("dynamicbarcode");
BarcodeImageHandler.saveJPEG(
BarcodeFactory.createCode128("PRIMEFACES"), barcodeFile);
barcode = new DefaultStreamedContent(
new FileInputStream(barcodeFile), "image/jpeg");
} catch (Exception e) {
e.printStackTrace();
}
}
public BarcodeBean getBarcode() {
return this.barcode;
}
}
Displaying Regular Images
As  GraphicImage  extends  standard  graphicImage  component,  it  can  also  display  regular  non
dynamic images just like standard graphicImage component using name and optional library.
<p:graphicImage name="barcalogo.jpg" library="yourapp" />
How It Works
Dynamic image display works as follows;
•Dynamic image encryps its value expression string to generate a key.
•This key is appended to the image url that points to JSF resource handler.
•Custom PrimeFaces ResourceHandler gets the key from the url, decrypts the expression string to
something  like  #{bean.streamedContentValue},  evaluates  it  to  get  the  instance  of
StreamedContent from bean and streams contents to client.
239
PrimeFaces User Guide
As a result there will be 2 requests to display an image, first browser will make a request to load the
page and then another one to the dynamic image url that points to JSF resource handler. Please note
that you cannot use viewscope beans as they are not available in resource loading request.
Passing Parameters and Data Iteration
You can pass request parameters to the graphicImage via f:param tags, as a result the actual request
rendering the image can have access to these values. This is extremely handy to display dynamic
images if your image is in a data iteration component like datatable or ui:repeat.
StreamedContent
There are two StreamedContent implementations out of the box; DefaultStreamedContent is not
uses an InputStream and not serializable whereas the serializable ByteArrayContent uses a byte
array.
