Usage examples:

CADJAVA-595 - Last Author metadata information failed to get extracted

 String fileName1 = "example.dwg";

CadImage image = (CadImage) Image.load(fileName1);

CadSummaryInfo summary = image.getHeader().getSummaryInfo();

System.out.println(summary.getAuthor());

CADJAVA-598 - Support for OBJ format

 Image cadDoc = Image.load("example-580-W.obj");

CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();

rasterizationOptions.setPageWidth(cadDoc.getSize().getWidth());

rasterizationOptions.setPageHeight(cadDoc.getSize().getHeight());

PdfOptions CADf = new PdfOptions();

CADf.setVectorRasterizationOptions(rasterizationOptions);

cadDoc.save("example-580-W_custom.pdf", CADf);

CADJAVA-537 Read hyperlinks and OLE object links section

 CadImage cadImage = (CadImage)Image.load("Autocad sample.dwg");

for (CadBaseEntity entity : cadImage.getEntities())

{

    if (entity instanceof CadInsertObject)

    {

        CadBlockEntity block = cadImage.getBlockEntities().get_Item(((CadInsertObject)entity).getName());

        String value = block.getXRefPathName().getValue();

        if (value != null && !value.contentEquals(""))

        {

            block.getXRefPathName().setValue("new file reference.dwg");

        }

    }

    if (entity.getHyperlink() == "https://products.aspose.com")

    {

        entity.setHyperlink("https://www.aspose.com");

    }

}
