Automatización de capas de exportación a archivos

Hackeé un script jsx para hacerlo basado en el script Export Layers to Files. Solo admite la exportación png24 y no tiene diálogo. Asume que desea recortar la capa y que la ruta a la carpeta a la que desea exportar está codificada en el propio script. Para configurar la carpeta, cambie el valor de exportPatha una ruta absoluta.

Hola a todos y este es mi primer post.

Pensé que debería haber sido un comentario simple, ya que parece que no puedo encontrar la línea de código específica para resolver este problema de una manera mucho más rápida que la que se resuelve con los scripts integrados y las soluciones de carteles anteriores, sin embargo, ya que no tengo reputación. 50+ pero no puedo comentar y, por lo tanto, debo proporcionar una respuesta en su lugar.

Por lo tanto, mi sugerencia es simplemente emplear el archivo de código anterior, que parece casi idéntico a la plantilla incluida de Adobe PS.

Sin embargo, se recomienda un cambio.

/////////////////////////////////////////////////// ///////////////////////////// // Función: zeroSuppress // Uso: devolver una cadena rellenada con dígito(s) // Entrada : número para convertir, se necesita el recuento de dígitos // Retorno: cadena rellenada a la longitud del dígito ///////////////////////////////// /////////////////////////////////////////////// función removeAllInvisible(docRef ) {

// tenga en cuenta el comentario a continuación

// removeAllInvisibleArtLayers(docRef);

removeAllEmptyLayerSets(docRef);

}

debe comentarse para acelerar la ejecución.

Preferiblemente, si alguien puede publicar la forma más eficiente de aplanar la imagen en esta función, deberíamos tener un código de trabajo que sea mucho más eficiente para el propósito descrito anteriormente.

Perdone mi entrada de novato, pero estudio "teoría de producción LEAN" y no "diseño gráfico" en mi universidad local.
