Post subject:  Embedding a logo in a RTF
Trying to use version MigraDoc 1.50.5147.0 to embed a gif logo into a RTF document. Used the readily available examples and it's working for PDF but not when I render a RTF.

static string MigraDocFilenameFromByteArray(byte[] image)
{
return "base64:" + Convert.ToBase64String(image);
}

void LoadLogo()
{
byte[] imageArray = Library.Helpers.FileUtils.ReadFile(LogoFilename);

string strEmbeddedImage = MigraDocFilenameFromByteArray(imageArray);
CurrentDocument.LastSection.Headers.FirstPage.AddImage(strEmbeddedImage);
}


public static byte[] ReadFile(string sPath)
{
//Initialize byte array with a null value initially.
byte[] data = null;

//Use FileInfo object to get file size.
FileInfo fInfo = new FileInfo(sPath);
long numBytes = fInfo.Length;

//Open FileStream to read file
FileStream fStream = new FileStream(sPath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
//FileStream(path, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))

//Use BinaryReader to read file stream into byte array.
BinaryReader br = new BinaryReader(fStream, Encoding.Default);

//When you use BinaryReader, you need to supply number of bytes to read from file.
//In this case we want to read entire file. So supplying total number of bytes.
data = br.ReadBytes((int)numBytes);

//Close BinaryReader
br.Close();

//Close FileStream
fStream.Close();

return data;
}

RTFM: BASE64 works for PDF, but not yet for RTF. Just use normal images from files.

The RTF is generated on a web server thru a web service and downloaded to the client. When the images are added to the RTF, the image is missing when downloaded. I was hoping to embed the image in the RTF like the PDF.

I separated the logic between the PDF & RTF generation and the image is now appearing in the downloaded RTF document.

Although I'm now able to embed the logo image in the PDF, I've lost the ability to position the image on the header, either left, right or center. How can I add positioning to the image i'm embedding?
