Attached is a Word document with an image in the header that when converted to pdf blows up and covers most of the page.
Also attached is the same pdf but with the image in the page. No issues when converting to pdf.
I tested on Syncfusion 17.x and the latest 22.214.171.124
I also tested with SkiaSharp versions 1.59.3 and 1.68.0.
The code used to convert is default code:
WordDocument document = new WordDocument(stream, syncfusionFormatType.Docx);
DocIORenderer render = new DocIORenderer();
PdfDocument pdfDocument = render.ConvertToPDF(document);
