Exception "Null Pointer" when generating SVG using Aspose.Slides for Java

Aspose.Slides Product Family

HI!

I have a problem when invoking “writeAsSvg()” in different scenarios. The problem is that a NullPointerException is thrown from an internal class and I don’t know the reason.

This is the stack trace:

  • com.aspose.slides.afc in if
  • com.aspose.slides.GeometryShape in do
  • com.aspose.slides.AutoShape in do
  • com.aspose.slides.Shape in do
  • com.aspose.slides.Shape in if
  • com.aspose.slides.Shape$2 in do
  • com.aspose.slides.internal.kz.do in do
  • com.aspose.slides.internal.kz.if in do
  • com.aspose.slides.Shape in writeAsSvg

Hi!

I have updated to the version 19.1 and I have the same problem.

  • Operating system: Ubuntu 18.04.2 LTS
  • Java: openjdk version “1.8.0_191”
  • Source PPT: I attached to this message
  • Sample code:

IPresentation ppt = new com.aspose.slides.Presentation("/home/users/Downloads/Credenciales MHSM_2.pptx");

/**
Code to license
**/

for (IShape shape : ppt.getSlides().get_Item(0).getShapes()) {
SVGOptions opts = new SVGOptions();
opts.setPicturesCompression(0);
shape.writeAsSvg(new FileOutputStream(new File("/home/user/folder/image.svg")), opts);
}

Thank you for your response!
