Chart Title color went off when exporting to PDF using Aspose.Slides for .NET


we’re using Aspose Slides .NET 18.12.0 to convert a PPTX file to a PDF. Most of it seems to work ok, but we’re having a few issues with charts and colors:

Rendered by Powerpoint PDF export (307.8 KB)
Rendered by Aspose PDF export (272.4 KB)

You can see that the colors rendered by Aspose are off. The title is black instead of white, the colors in the chart are switched as well. Also font size seems to be a bit off.

This seems to be a general issue with charts in the whole document. Also the waterfall chart on slide 6 is not rendered at all.

The presentation is attached in the following zip file: (2.3 MB)

Here’s the PDF rendered when exporting using Powerpoint Save as PDF:
2016Test_exported_using_powerpoint.pdf (1.3 MB)

And here’s the PDF rendered by Aspose:
tmpFA17.tmp.pdf (1.0 MB)

using the following C# code:

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Aspose.Slides.Warnings;

namespace AsposePowerpointExportSample
    class Program
        static void Main(string[] args)
            Aspose.Slides.License slides = new Aspose.Slides.License();

            var inputFilePath = "2016Test.pptx";

            var presentation = new Aspose.Slides.Presentation(inputFilePath);
            var saveOptions = new Aspose.Slides.Export.PdfOptions
                JpegQuality = (byte)80,
                BestImagesCompressionRatio = true

            var tempFilePath = Path.GetTempFileName() + ".pdf";
            using (var fs = new FileStream(tempFilePath, FileMode.Create))
                presentation.Save(fs, Aspose.Slides.Export.SaveFormat.Pdf, saveOptions);



Is this a bug in Aspose or are there any options that can be tuned to fully support this file?
