Highlight colors not rendered in thumbnails

Hi Aspose Support,

I have the problem that highlighted text is not rendered in the generated thumbnails. Please have a look at the attached test presentation. I used following code to generate a png thumbnail:

public void testThumbnailGeneration() throws Exception{

InputStream pres = TestThumbnailGeneration.class.getResourceAsStream(“highlightColor.pptx”);

PresentationEx presentation = new PresentationEx(pres);

BufferedImage image = presentation.getSlides().get(0).getThumbnail(1f ,1f);

String targetFolderPath = TestThumbnailGeneration.class.getResource("/").getPath();

File targetFolder = new File(targetFolderPath);

ImageIO.write(image, “png”, new File(targetFolder, “highlightColor.png”));


thx for your help
