hola, he combinado algunos scripts en este foro, para crear algo similar al procesador de photoshop, me gustaría saber si este script se puede mejorar o simplificar para que procese más rápido.
este script procesa un Ai a Psd, Pdf, Png, Jpg y Ai v3 hasta la CC2015, además puede escoger la resolución de la exportación para PSD,PNG y JPG, también uno puede elegir que busque en subcarpetas
var format = prompt('Choose a File Type Extension :\nai, psd, pdf, jpg, png', "png", 'Batch');
if (format == "ai" || format == "psd" || format == "pdf" || format == "jpg" || format == "png") {
if (format == "jpg" || format == "png" || format == "psd") {
var res = prompt('DPI resolution ', 300, 'Batch');
}
if (format == "ai") {
alert("Adobe Ai versions :\n\nAdobe 3.0 = 3\n\nAdobe 8.0 = 8\n\nAdobe 9.0 = 9\n\nAdobe 10 = 10\n\nAdobe CS1 = 11\n\nAdobe CS2 = 12\n\nAdobe CS3 = 13\n\nAdobe CS4 = 14\n\nAdobe CS5 = 15\n\nAdobe CS6 = 16\n\nAdobe CC 2013,2014,2015 = 17")

}
