A veces, necesitas generar imágenes de Barras de Datos con Formato Condicional. Puedes usar el método DataBar.to_image() de Aspose.Cells para crear estas imágenes. Este artículo muestra cómo generar una imagen de barra de datos usando Aspose.Cells para Python via .NET.
El siguiente código de ejemplo genera la imagen de la Barra de Datos de la celda C1. Primero, accede al objeto de condición de formato de la celda, y luego a partir de ese objeto, accede al DataBar y usa su método to_image() para generar la imagen de la celda. Finalmente, guarda la imagen en disco.
