Converting PPT slides to image mess up fonts


For the attached presentation, (2.2 MB), attempting to get the thumbnails for slides reverses Hebrew text from RTL to LTR, and messes up the fonts.
The PPT uses neither system fonts nor embedded fonts. I’ve tried to manipulate the fonts using the Aspose FontsLoader and FontsManager classes, but without success. It looks good in PowerPoint but not after Aspose conversion.

Can you please assist? Here’s the sample code:

Presentation pres = new Presentation(“pres_menora.pptx”);
for (ISlide slide : pres.getSlides()) {
BufferedImage image = slide.getThumbnail(1f, 1f);
ImageIO.write(image, “jpeg”, new File(“pres” + slide.getSlideNumber() + “.jpg”));
