I was able to convert each pptx slide to multiples/separate svg images with the following code:
//Getting last slide index
int lastSlidePosition=presentation.getSlides().size();
SlideEx slide =null;
//Iterating through every presentation slide and generating SVG image
for (int i = 0; i < lastSlidePosition; i++)
{
//Accessing Slides
slide = presentation.getSlides().get_Item(i);
slide.writeAsSvg(new FileOutputStream(path + i + ".svg"));
}
But I whant to converte all pptx slides to a single svg file.
The whole presentation cannot be saved to a single svg using Aspose.Slides. However, you can do
