Gambar DGN

Gambar Format DGN Sebagai Bagian dari DWG

Aspose.CAD untuk Java memungkinkan pengembang untuk mengekspor file DWG dengan DGN underlay yang disematkan di dalamnya. Berikut adalah kode yang menunjukkan cara mengakses DGN underlay di dalam file DWG saat mengekspor file 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);

Dukungan entitas 3D untuk DGN v7

Aspose.CAD untuk Java API telah memperkenalkan fungsionalitas untuk memuat file DGN AutoCAD dan mendukung entitas 3D untuk DGN v7. Kelas CadImage memiliki tujuan tersebut. Setiap gambar DGN mendukung 9 tampilan yang telah ditentukan sebelumnya. Ini dinyatakan dari 1 hingga 9. Jika tampilan tidak didefinisikan pada ekspor, untuk format keluaran multi-halaman (seperti PDF) semua tampilan akan diekspor, masing-masing pada halaman terpisah. Entitas 3D didukung pada format file DGN, serta 2D. VectorRasterizationOptions.TypeOfEntities tidak lagi digunakan untuk format DGN (baik 2D maupun 3D didukung secara bersamaan).

Kode contoh untuk melihat elemen DGN yang didukung.

String fileName = dataDir + "Nikon_D90_Camera.dgn";
String outFile  = dataDir + "Nikon_D90_Camera.dgn";
            
DgnImage objImage = (DgnImage)com.aspose.cad.Image.load(fileName);
            
    PdfOptions options = new PdfOptions();
    CadRasterizationOptions vectorOptions = new CadRasterizationOptions();
    vectorOptions.setPageWidth(1500);
    vectorOptions.setPageHeight(1500);
    vectorOptions.setAutomaticLayoutsScaling(true);
    vectorOptions.setBackgroundColor(Color.getBlack());
    vectorOptions.setLayouts(new String[] { "1", "2", "3", "9" });//only export 4 (1,2,3 and 9) views
    options.setVectorRasterizationOptions(vectorOptions);

    objImage.save(outFile, options);
            

// Input and Output file paths
String fileName = "BlockRefDgn.dwg";
String outPath = "BlockRefDgn.dwg.pdf";
       
DgnImage dgnImage = (DgnImage)Image.load(dataDir);
{
    for (DgnDrawingElementBase element : dgnImage.getElements())
    {
        switch (element.getMetadata().getType())
        {
            case DgnElementType.Line:
            case DgnElementType.Ellipse:
            case DgnElementType.Curve:
            case DgnElementType.BSplineCurveHeader:

            case DgnElementType.ComplexChainHeader:
            {
                //previously supported entities, now supported also for 3D
                break;
            }

            case DgnElementType.SolidHeader3D:
            case DgnElementType.Cone:
            case DgnElementType.CellHeader:
            {
                //supported 3D entities
                break;
            }
        }
