Muy bien las librerias mencionadas funcionan bien si hablamos de OCR pero el ejemplo que tienen en su pagina web.. para delphi el cual es el siguiente me da un problema... ya que solo permite cargar la imagen con su dirección en un Edit ... Pues a mí me gustaría que se extraiga el texto directamente de un Image y no sé como hacerlo si alguien me puede ayudar muchas gracias

El codigo es el siguiente
