Sorry, Gents,
I thought more about the compiler error that I incurred and come to think that I did not put forward the problem correctly.
Please consider the following:
I had taken the error message "! Undefined control sequence." for an indication that the compiler had not found the macro or the image file itself to include as graphics.
I believe my inference was false.
Reviewing the log file, the context of the error looks as follows:
File: image.jpg Graphic file (type jpg)
<use image.jpg>
Package pdftex.def Info: image.jpg used on input line 214.
(pdftex.def) Requested size: 539.99869pt x 119.9997pt.
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.
It seems the image was found and included, but the error occurred in the subsequent processing.
The whole idea is to include a digital signature inside the optional argument of the closing command of a letter.
\closing[%
\hspace*{-5mm}%
\mysignature% <- here is an \includegraphics command using the package graphics, see post above
]
{%
\MfG%
}
Would it be possible to readdress the problem as presented now?
Please consider.
Many thanks.
Dear Johannes and Stefan,
With your advice I could solve the problem.
I changed to graphicx (and ngerman).
The file runs without error. Output is fine.
You made my day.
Thank you very much indeed.
I would have been lost without you.
Speak soon, mb
