Ok, makes sense.

Yes surely. What got me confused earlier (and then thinking!) is that
by this method, we can  set the width and height spinboxes to be
specified only in inches (avoiding the pixel-inches <logic>
alltogether in xml). For jpeg/png, we can use width=$width*$resolution
(height=$height*$resolution) when either of them is provided (in
inches) and your solution ("par("din")[1]".$resolution) when both are
auto. As for ps/pdf, the usual width=$width (height=$height), in
inches will work. Is this a "confusing oversimplification"?

My Pseudo code would look like this:

if ($png_jpeg) {
        $resolution = getRK_val ("resolution")
} else {
        $resolution = 1;
}
if ($png_jpeg && $width_automatic && $height_automatic) {
        // png() and jpeg() need at least one of width/height
        $width_option = ", width=par("din")[1]*" . $resolution;
} else {
        if (!$width_automatic) {
                $width_option = ", width=" . getRKval ("width")*$resolution;
        }
        // same for height..
}

Thats all! No more logic mess!
