KOMA letter with logo towards top of page

Question

I would like to write a KOMA letter with a logo towards the top right corner of the first page. (See the attached image.)

I'm using LuaLaTeX in TeXLive on Win10.

So far, my efforts to setkomavar{firsthead} and setkomavar{fromlogo} do not produce an image.

Using documentclass{scrartcl} and scrletter, I was able to set the logo using firsthead, but my attempts to move it up failed.

A MWE:

\documentclass[
 a4paper,
 11pt,
 backaddress=off,
 pagenumber=no,
 fromalign=locationright,
 enlargefirstpage=false,
 foldmarks=off]{scrlttr2}
\usepackage[margin=2cm]{geometry}
\usepackage{graphicx}
\usepackage{lipsum}
\usepackage{mwe}

%\makeatletter
%  \@setplength{firstheadvpos}{-20mm} % doesn't seem to move logo up
%  \@addtoplength[-]{firstheadvpos}{40mm} % also seems to do nothing
%\makeatother

\setkomavar{fromaddress}{Santa Claus\\ North Pole H0H 0H0\\ Canada}
% \setkomavar{firsthead}{\hfill\includegraphics[height=3cm]{example-image}}
\setkomavar{fromlogo}{\includegraphics[width=3cm]{example-image}}
  
\begin{document}
\begin{letter}{Colin Rowat \\ South Pole}
\opening{Dear Colin,}
\lipsum
\closing{Ho Ho Ho,}
\end{letter}
\end{document}

Answer 1

You could add fromlogo=true to the options and then

\setkomavar{fromlogo}{\smash{\raisebox{1cm}{\includegraphics[width=3cm]{example-image}}}}

to move the logo up:

\documentclass[
 a4paper,
 11pt,
 backaddress=off,
 pagenumber=no,
 fromalign=locationright,
 fromlogo=true,% <- added
 enlargefirstpage=false,
 foldmarks=off
]{scrlttr2}
\usepackage[margin=2cm]{geometry}
\usepackage{graphicx}
\usepackage{lipsum}
\usepackage{mwe}

\setkomavar{fromaddress}{Santa Claus\\ North Pole H0H 0H0\\ Canada}
\setkomavar{fromlogo}{\smash{\raisebox{1cm}{\includegraphics[width=3cm]{example-image}}}}
  
\begin{document}
\begin{letter}{Colin Rowat \\ South Pole}
\opening{Dear Colin,}
\lipsum
\closing{Ho Ho Ho,}
\end{letter}
\end{document}

---

Or you can remove the fromalign option and add

\setkomavar{fromaddress}{Santa Claus\\ North Pole H0H 0H0\\ Canada}
\setkomavar{fromlogo}{\includegraphics[width=3cm]{example-image}}
\setkomavar{location}{\raggedleft\usekomavar{fromaddress}}
\setkomavar{firsthead}{\hfill\usekomavar{fromlogo}}

\documentclass[
 a4paper,
 11pt,
 backaddress=off,
 pagenumber=no,
 %fromalign=locationright,% <- removed
 enlargefirstpage=false,
 foldmarks=off
]{scrlttr2}
\usepackage[margin=2cm]{geometry}
\usepackage{graphicx}
\usepackage{lipsum}
\usepackage{mwe}

\setkomavar{fromaddress}{Santa Claus\\ North Pole H0H 0H0\\ Canada}
\setkomavar{fromlogo}{\includegraphics[width=3cm]{example-image}}
\setkomavar{location}{\raggedleft\usekomavar{fromaddress}}
\setkomavar{firsthead}{\hfill\usekomavar{fromlogo}}

\begin{document}
\begin{letter}{Colin Rowat \\ South Pole}
\opening{Dear Colin,}
\lipsum
\closing{Ho Ho Ho,}
\end{letter}
\end{document}
