You can use something like
B4X:
    Dim xui As XUI
    
    Dim img  As B4XBitmap
    img =  xui.LoadBitmap(dir,File)
    img = img.Rotate(90)
            
    Dim Out As OutputStream
    Out = File.OpenOutput(dir, File, False)
    img.WriteToStream(Out, 100,   "JPEG")
    Out.Close

Fabio, it should work like this
B4X:
Dim B4XBase As B4XView = xImageView1.GetBase
Dim Image As B4XBitmap = B4XBase.Snapshot

try inserting the view into a panel and then capture the panel image
B4X:
Dim B4XBasePanel As B4XView = xImageView1.GetBase.parent
Dim Image As B4XBitmap = B4XBasePanel.Snapshot
