convert lena.jpg -font ubuntu -fill skyblue -stroke blue -strokewidth 1 -undercolor white -pointsize 36 -gravity south -annotate 0x10+0+20 "TESTING" lena_annotate.jpg

-font is the font name (your can use the path to the font.suffix as well)
-fill is the color of the font
-stroke is the outline color
-strokewidth is the thickness of the stroke outline
-undercolor is the color to put under the text -- you can leave that off for no underfloor.
-gravity is where the text will be placed in the image (south means at the center of the bottom)
-geometry is the offset from the gravity position
-annotate 0x10+0+20 --- 0x10 means to slant only in y by 10 (if 10x10 it will rotate rather than slant); +0+20 means raise by 20 upwards and shift left/right by 0. If you do not want any slanting, then use 0x0. If you do not want it shifted up, then use +0+0.
"TESTING" is the text you want to use.
