    Remarks
    This processing command is designed to determine orientation of images containing mostly text in Roman alphabet which is rotated by multiple of 90 degrees (e.g., scanned documents with unknown orientation).
    The command is not designed for:
    • non-textual images
    • non-Roman text
    • Roman text with only capital letters
    • rotated text with rotation angle other than multiple of 90 degrees (use DeskewCommand)
    • images with only few words, insufficient for making a conclusion

    Use DeskewCommand prior to this command to align rotated image. Use other processing commands prior to this command to improve detection quality of noisy image.
