Dim bmp As Bitmap

    rbmp.Initialize
    bmp.Initialize(FP, "1.jpg")
    exif.Initialize(FP, "1.jpg")
    casa =  exif.getAttribute(exif.TAG_ORIENTATION)
    If casa = 6 Then
    exif.setAttribute(exif.TAG_ORIENTATION, 1)
    exif.saveAttributes
    If bmp.width>bmp.height Then     
    bmp = rbmp.Rotate(bmp, 90)
    rbmp.writeBitmapToFile(bmp,FP ,"1.jpg", 100 )
