g.region rast=elevation
for STYLE in classic line solid hollow full_checker part_checker mixed_checker tail_checker up_ticks down_ticks both_ticks arrow_ends
do
echo ${STYLE}
export GRASS_PNGFILE=${STYLE}.png
d.barscale style=${STYLE} at=20,20
mogrify -trim ${STYLE}.png
identify -format "%[fx:w]x%[fx:h]" ${STYLE}.png
convert ${STYLE}.png -gravity center -background white -extent 170x24 ${STYLE}.png
