Check the picture Exif orientation with the JpegUtils library: http://www.b4x.com/android/help/jpegutils.html

@Erel how can i know the rotation?

msg.Append("Orientação : ").Append(exif.getAttribute(exif.TAG_ORIENTATION)).Append(CRLF)

on the galaxy devices this return 6 and image is saved on landscape


on another devices is 0 or 1 and is saved on portrait < what i want


i tested on galaxy = 6
moto g = 0




can help me how to rotate landscape for portrait?

You can see the constants values here: http://developer.android.com/reference/android/media/ExifInterface.html#ORIENTATION_ROTATE_270

You will need to rotate the image and save it in a new file. See this post: http://www.b4x.com/android/forum/threads/file-rotation-cant-get-it-done.41391/#post-248945

ty i m fixed with this code

    Dim bmp As Bitmap
    Dim rbmp As RSImageProcessing
    Dim casa As String
    Dim exif As ExifData
   
    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 )
    End If
    End If
