SVG generated from flattened PDF has troubles with highlighted text

Aspose.PDF Product Family
1

Hello, here is my problem,

Original_highlight.pdf contains two highlight annotations, the green is made with adobe reader, the yellow with aspose.
I flatten it with aspose > flattened_highlight.pdf : the output pdf seems valid, it displays correctly in adobe or foxit.
In Aspose, I can generate a PNG image and it’s fine.

But if I generate an SVG image from the flattened PDF, the yellow highlight generated with Aspose hide the text behind while the green highlight made with Adobe is correct.
Checking the svg file, there is a “blend-mode:multiply” used for the green highlight that allow the correct display.

Regards

namespace Aspose.Pdf.Examples.CSharp.AsposePDF.DocumentConversion
{
    public class PDFToSVG
    {
        public static void Run()
        {
            // ExStart:PDFToSVG
            // The path to the documents directory.
            string dataDir = RunExamples.GetDataDir_AsposePdf_DocumentConversion();
            // Load PDF document
            Document doc = new Document(@"C:\TEST\bugreport\flattened_highlight.pdf");
            // Instantiate an object of SvgSaveOptions
            SvgSaveOptions saveOptions = new SvgSaveOptions();
            // Do not compress SVG image to Zip archive
            saveOptions.CompressOutputToZipArchive = false;
            // Save the output in SVG files
            doc.Save(@"C:\TEST\bugreport\from_sample.svg", saveOptions);
            // ExEnd:PDFToSVG
        }
    }
}
