Problem setting slide sizes with Aspose.Slide 15.4.0

Aspose.Slides Product Family

Hello Aspose team,

if i create a new presentation, set the SlideSizeType.A3Paper and try to save this presentation, i get a NullPointerException. This behavior occurs also for some other SlideSizeTypes.

There is a dirty workaround. After setting the SlideSizeType, i read the dimension. Then i set the SlideSizeType.Custom and set the previously read dimension as size. Now the presentation is savable.

My code:
public class AsposeSlideSizeWorkaroundTest {

@Test
public void testA3Paper() throws Exception {
final Presentation pres = new Presentation();
pres.getSlideSize().setType(SlideSizeType.A3Paper);

try (ByteArrayOutputStream out = new ByteArrayOutputStream()) {
// this throws a NullPointerException
pres.save(out, SaveFormat.Ppt);
}
}

@Test
public void testA3PaperAsCustomWorkaround() throws Exception {
final Presentation pres = new Presentation();
pres.getSlideSize().setType(SlideSizeType.A3Paper);

// workaround: read the a3 dimension and set it again as custom size
final Dimension2D dim = pres.getSlideSize().getSize();
pres.getSlideSize().setType(SlideSizeType.Custom);
pres.getSlideSize().setSize(dim);

try (ByteArrayOutputStream out = new ByteArrayOutputStream()) {
// this works
pres.save(out, SaveFormat.Ppt);
}
}
}
