                PageWidth = 1200,
                PageHeight = 1200,
                ExportAllLayoutContent = true,
                Quality = new RasterizationQuality()

                PenOptions = new PenOptions()
                    StartCap = LineCap.Square,
                    EndCap = LineCap.Square
            ImageOptionsBase options = new PngOptions();

I have observed the sample code and output shared by you. An issue with ID CADNET-1098 has been created in our issue tracking system to further investigate and resolve the issue. This thread has been linked with the issue so that you may be notified once the issue will be fixed.

Just wondering what the status is on this? We have a client wanting this feature and we might have to go with another product if it isn’t fixed soon. Thanks!
