DGN Drawing
Dibujo del formato DGN como parte de DWG
Aspose.CAD para Java permite a los desarrolladores exportar un archivo DWG con un fondo DGN incrustado. A continuación, se muestra el código que demuestra cómo acceder al fondo DGN dentro de un archivo DWG al exportar el archivo DWG.
// Input and Output file paths | |
String dataDir = Utils.getDataDir(ExportDGNAsPartofDWG.class) + "ExportingDGN/"; | |
// Input and Output file paths | |
String fileName = dataDir + "BlockRefDgn.dwg"; | |
String outPath = dataDir +"BlockRefDgn.dwg.pdf"; | |
// Create an instance of PdfOptions class as we are exporting the DWG file to PDF format | |
com.aspose.cad.imageoptions.PdfOptions exportOptions = new com.aspose.cad.imageoptions.PdfOptions(); | |
// Load any existing DWG file as image and convert it to CadImage type | |
com.aspose.cad.fileformats.cad.CadImage cadImage = (com.aspose.cad.fileformats.cad.CadImage) com.aspose.cad.Image.load(fileName); | |
// Go through each entity inside the DWG file | |
for (com.aspose.cad.fileformats.cad.cadobjects.CadBaseEntity baseEntity : cadImage.getEntities()) | |
{ | |
// Check if entity is an image definition | |
if (baseEntity.getTypeName() == com.aspose.cad.fileformats.cad.cadconsts.CadEntityTypeName.DGNUNDERLAY) | |
{ | |
com.aspose.cad.fileformats.cad.cadobjects.CadDgnUnderlay dgnFile = (com.aspose.cad.fileformats.cad.cadobjects.CadDgnUnderlay)baseEntity; | |
// Get external reference to object | |
System.out.println(dgnFile.getUnderlayPath()); | |
} | |
} | |
// Define settings for CadRasterizationOptions object | |
com.aspose.cad.imageoptions.CadRasterizationOptions vectorRasterizationOptions = new com.aspose.cad.imageoptions.CadRasterizationOptions(); | |
vectorRasterizationOptions.setPageWidth(1600); | |
vectorRasterizationOptions.setPageHeight(1600); | |
vectorRasterizationOptions.setLayouts(new String[] { "Model" }); | |
vectorRasterizationOptions.setAutomaticLayoutsScaling(false); | |
vectorRasterizationOptions.setNoScaling(true); | |
vectorRasterizationOptions.setBackgroundColor(com.aspose.cad.Color.getBlack()); | |
vectorRasterizationOptions.setDrawType(com.aspose.cad.fileformats.cad.CadDrawTypeMode.UseObjectColor); | |
// Set Vector Rasterization Options | |
exportOptions.setVectorRasterizationOptions(vectorRasterizationOptions); | |
// Export the DWG to PDF by calling Save method | |
cadImage.save(outPath, exportOptions); | |
Soporte de entidades 3D para DGN v7
La API Aspose.CAD para Java ha introducido la funcionalidad para cargar un archivo DGN de AutoCAD y soportar entidades 3D para DGN v7. La clase CadImage sirve para este propósito. Cada imagen DGN soporta 9 vistas predefinidas. Estas se enumeran de 1 a 9. Si no se define la vista en la exportación, para formatos de salida de varias páginas (como PDF) se exportarán todas las vistas, cada una en una página separada. Se soportan entidades 3D en el formato de archivo DGN, así como entidades 2D. VectorRasterizationOptions.TypeOfEntities ya no se utiliza para el formato DGN (tanto 2D como 3D se soportan simultáneamente).
