Exception"ImageSaveException: Image export failed" while converting EMF into PNG using Aspose.Imaging for Java

Aspose.Imaging Product Family
1

Hi,

I tried to save the attached emf image as png with the following java code:

import java.io.ByteArrayOutputStream;

import com.aspose.imaging.Image;
import com.aspose.imaging.imageoptions.PngOptions;
import com.aspose.imaging.imageoptions.EmfRasterizationOptions;

public class ImageRenderEmf
{
    public static void main( String[] args ) throws Exception
    {
		Image image = Image.load( "example.emf" );
				
		// Create output stream
		ByteArrayOutputStream bytearrayoutputStream = new ByteArrayOutputStream();
		
		PngOptions pngOptions = new PngOptions();

		pngOptions.setVectorRasterizationOptions( new EmfRasterizationOptions() );
		pngOptions.getVectorRasterizationOptions().setPageWidth( image.getWidth() );
		pngOptions.getVectorRasterizationOptions().setPageHeight( image.getHeight() );

		image.save( bytearrayoutputStream, pngOptions );
	}
}

The following exception is thrown:

Exception in thread "main" class com.aspose.imaging.coreexceptions.ImageSaveException: Image export failed. ---> java.lang.NullPointerException
