Abstract

La invención se relaciona con un método para elaborar un pantógrafo. El método incluye las etapas de definir un mensaje para ser visualizado sobre el pantógrafo, formando un formato de pixel de trasfondo y un patrón de grupo de pixeles de primer plano. El patrón de grupo de primer piano se elabore a partir de la formación de pixeles de trasfondo. Los pixeles adyacentes en el patrón de trasfondo se combinan para formar grupos de pixeles. El patrón de primer plano de grupos de pixeles se utiliza para llenarlos caracteres de un mensaje de pantógrafo.
