Hi There

I check this issue again, and found there are still something missing in the result with 16.10.0 in Linux environment.

Here is my code for test:
Presentation pre = new Presentation(“7MB.ppt”);

String dirName = UUID.randomUUID().toString();
File file = new File("" + dirName);

for (int i = 0; i < pre.getSlides().size(); i++) {

new FileOutputStream(""
+ dirName + “/” + (i + 1) + “.svg”));


This issue happens in page #19.
I have upload a comparison image, the PowerPoint file, and the result.
Please check it and analyze this issue again, thank you
