This example is worked assuming ~3 GB of free RAM(only x64 systems)

//without license
License license = new License();
license.setLicense("");

String baseFolder = "D:\\";
String file = "image7.emf";
String inputFileName = baseFolder + file;
String outputFileName = inputFileName + ".svg";
try (Image image = Image.load(inputFileName))
{
    image.save(outputFileName, new SvgOptions());
}


For cases with a limited RAM resource, it is necessary to modify the library:
  - Implement a partial image storage in APS format
  - Implement read/write a partial image  from APS format
