SVG as Image improperly rendered as bitmap

Aspose.PDF Product Family

When importing a SVG as an Image, its inserted into the PDF as a raster image with bad compression as well as replacing transparency with a white background. How do I get it to insert it as a vector image drawing?

double originalWidth = 0, originalHeight = 0, ratioX = 1, ratioY = 1, ratio = 1;

//Using SVG Nuget Package to accurately read SVG dimensions
//and to change them
//https: //github.com/vvvv/SVG
SvgDocument svgDocument = Svg.SvgDocument.Open(imagePath);
originalWidth = svgDocument.Width;
originalHeight = svgDocument.Height;

//aspect ratios
ratioX = maxWidth / originalWidth ?? 1;
ratioY = maxHeight / originalHeight ?? 1;

//smallest ratio wins
ratio = Math.Min(ratioX, ratioY);

float newWidth = (float)Math.Ceiling(originalWidth * ratio);
float newHeight = (float)Math.Ceiling(originalHeight * ratio);

svgDocument.Width = new Svg.SvgUnit((float)newWidth);
svgDocument.Height = new Svg.SvgUnit((float)newHeight);

var svg = new Image
{
   FileType = ImageFileType.Svg,
   IsInLineParagraph = true,

   // new height and width
   FixWidth = newWidth,
   FixHeight = newHeight,
   IsApplyResolution = true
};

var stream = new MemoryStream();
svgDocument.Write(stream);

svg.ImageStream = stream;

return svg;

I would have uploaded the SVG but your forum blocks that filetype.

double? maxHeight = 60;

Still an issue even with the latest version, 21.9.0

       var icon = new Image
        {
            File = speciesRightTagPath,
            FileType = ImageFileType.Svg,
            FixWidth = 284,
            FixHeight = 96,
            IsApplyResolution = false,
            ImageScale = 1,
        };
        FloatingBox iconBox = new FloatingBox();
        iconBox.Paragraphs.Add(icon);
        iconBox.VerticalAlignment = VerticalAlignment.Center;
        iconBox.Left = DocConfig.PageWidth - DocConfig.TrimBoxOffset - icon.FixWidth;
        iconBox.Top = box.Top - topMargin;

        box.Paragraphs.Add(iconBox);

What’s the status of this issue?

I’ve reviewed version 23.1.1 and the SVG images are still being improperly embedded within the document.

We’re evaluating the Aspose.Pdf license for an upgrade and this would hider us from moving forward.
