You can change the size of a JavaServer Faces (JSF) image on a Faces JSP page with EGL code. You must use a Faces image control; an EGL JSF Handler cannot directly change ordinary HTML image tags.
import com.ibm.egl.jsf.*
imageEx1 HtmlGraphicImageEx;
imageEx1 = myViewRoot.findComponent("imageEx1");
imageEx1.setWidth("300");
imageEx1.setHeight("300");
