The setBackgroundValue() method was added in ImageJ 1.34p.
Here is a macro that rotates an image by a specified number of degrees,
filling with the image average.
requires("1.34p");
angle = 25;
getRawStatistics(area, mean);
setBackgroundColor(mean, mean, mean);
run("Arbitrarily...", "interpolate fill angle="+angle);
