I have a panel where I put a PDF file. This work with the src parameters:

id: 'pdfFrame',xtype: 'component',
autoEl: {
    tag: 'iframe',
    style: 'height: 100%; width: 100%; border: none',
    src: 'FILE.PDF'
But now I receive a ZIP file which contain the PDF file (or much). I must extract the file (I do that) and give the stream to the panel (I can't save the file for use it). How can I give the stream for display it?

I must perhaps give the data by an other way?

Thank you in advance for your answers
