Caption is not working correctly when IM is compiled with PANGO (Pangoft2 1.28.4). The result includes the word "caption:" along with the desired text --- and I do not believe it is getting the font, doing autoscaling of pointsize and centering correctly.
convert -background none -fill black \
-font Arial -gravity center \
-size 100x100 caption:"this is a test" \
