*hi, I'm answer me self :-) maybe someone have similar problems....for View
Raw Image question:in HTML5 this way is over Blob and
createObjectURL...under GWT for Blob I found much Implementations
(lib-gwt-file, html5gwt, elemental ...) but I had problems for create new
Blob Object..... ( I'm newbie....I don't understand this api ...) ok, for
create new Blob I write new JSINIimport
com.google.gwt.typedarrays.shared.ArrayBuffer;import
org.vectomatic.file.Blob;public class testjs { public static native Blob
craeteBlob( ArrayBuffer buf) /*-{ return new $wnd.Blob([buf], {type :
'image/jpeg'}); }-*/;}on client side Blob blob =testjs.craeteBlob(buff);
String objurl = FileUtils.createObjectURL(blob);but Blob and FileUtils is
from import org.vectomatic.file.Blob;import
org.vectomatic.file.FileUtils;I'm ask me now what is difference in between
using typedarrays.shared and elemental ? maybe some one have a link ?*
