Replace image inside .docx or .pdf in .net core c#

[Patricio Venegas B]

Hi,

I have a document in word (.docx), which then I transform it into .pdf, either within the word or the pdf I need to change an image (the image is always the same), 

I have looked for examples without reaching any solution

this is my c# net core code

var templatePath = "mypath\file.docx";

var docStream = new FileStream(templatePath, FileMode.Open, FileAccess.Read);

var wordDocument = new WordDocument(docStream, FormatType.Automatic);

//code replacing some values insde .docx

var docIORenderer = new DocIORenderer();

PdfDocument pdfDocument = docIORenderer.ConvertToPDF(wordDocument);

docIORenderer.Dispose();

wordDocument.Dispose();

var memoryStream = new MemoryStream();

pdfDocument.Save(memoryStream);

memoryStream.Position = 0;

pdfDocument.Close(true);

string fileName = "Output.pdf";

var file = File(memoryStream, "application/pdf", fileName);

Could you help me solve the problem described based on this code?
