Working with Hyperlinks

Update Hyperlink in a DWG

Aspose.CAD for Java allows you to access the hyperlink in an AutoCAD drawing using the CadBaseEntity.getHyperlink(). You can access each hyperlink from this collection one by one and edit its properties.

Sample Code

The following sample code accesses all the entities of the image and changes their Hyperlink property to the Aspose website.

String dataDir = Utils.getDataDir(EditHyperlink.class) + "DWGDrawings/";
      
        
CadImage cadImage = (CadImage)Image.load(dataDir + "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");
    }
}
