Text is not being rendered when exporting slides as thumbnails

Hi,


We are currently encountering an issue while trying to export presentation’s slides as thumbnails with Aspose.Slides for .NET. The text is missing in all the generated thumbnails (any other shape is correctly rendered however).

You will find the presentation sample in attachment ; here is the code that we use (pretty basic) :

using (Aspose.Slides.Presentation presentation = new Aspose.Slides.Presentation(“sample.pptx”))
{
for (int i = 0; i < presentation.Slides.Count; ++i)
{
// Generating slide thumbnail
// User defined dimension
int desiredY = 650;

// Getting scaled value of X and Y
float ScaleY = (float)(1.0 / presentation.SlideSize.Size.Height) * desiredY;

presentation.Slides[i].GetThumbnail(ScaleY, ScaleY).Save(“thumbnail” + i + “.jpeg”, System.Drawing.Imaging.ImageFormat.Jpeg);
}
}


Configuration :
macOS 10.12.1 (Sierra)
Mono 4.6
Aspose.Slides for .NET 16.10.0
We build and deploy the application with Xamarin.Mac 2.8.0, Xamarin Studio 6.1.1.


Thanks in advance for your answer

UPDATE : I tried to use FontsLoader.LoadExternalFonts() method, specifying “/Library/Fonts” as the fonts directory. There is an improvement here, since some parts of text are eventually rendered. But this still doesn’t work well (see the picture in attachment).


Thanks,
