Transparent line showing as opaque in PNG, SVG conversion

Source visio has a “highlighting” effect of semitransparent line overlayed on a solid or dashed line. The highlighting comes out as opaque line in PNG and SVG conversions. Using Aspose.Diagram 18.8 for .NET. See attached Visio source, PNG and SVG conversions, and conversion (146.3 KB)


Thanks for contacting support.

We were able to replicate the issue using following code snippet in our environment:

// Load a VSD diagram, need to incorporate page parameter
Aspose.Diagram.Diagram theDiagram = new Aspose.Diagram.Diagram(dataDir + "Path_Highlighting.vsdx");
theDiagram.Save(dataDir + "PathHighlighting.svg", Aspose.Diagram.SaveFileFormat.SVG);
