Error when Saving As SVG

[tmarshall]

I am evaluating Spire.Presentation, and am getting the an error when saving the slides as SVG. I have tried with Spire.Presentation.Free 2.2.6 and Spire.Presentation 3.8.6 downloaded via Maven, both with the same outcome. The svg output is correctly generated. Appreciate any help to eliminate this please.

My code is:

Code: Select all

...
Presentation ppt = new Presentation();
ppt.loadFromFile(temp.getAbsolutePath(), FileFormat.AUTO);

//Save PPT document to images
SlideCollection slides = ppt.getSlides();
for (int i = 0; i < slides.size(); i++) {
  byte[] bytes = slides.get(i).SaveToSVG();
  FileOutputStream stream = new FileOutputStream(String.format("temp/ToSVG-%d.svg",  i));
  stream.write(bytes);
}
ppt.dispose();
...

And the error is:

Hello,

Hope you are doing well.
Regarding the issue SPIREPPT-1295, after further investigation, we found that it is because the images in your document are damaged (as shown below), this caused the program to throw the error. However, this doesn't affect the execution of the program, so you can see the svg output is correctly generated. Hope you can understand.
