from wand.color import Color
with Drawing() as draw:
draw.stroke_color = Color( 'black' )
draw.stroke_width = 1
draw.fill_color = Color( 'white' )
draw.circle(( 200 , 200 ),
( 100 , 100 ))
draw.font = '../Helvetica.ttf'
draw.font_size = 30
with Image(width = 400 , height = 400 , background = Color( '# 45ff33' )) as pic:
draw.text( int (pic.width / 3 ), int (pic.height / 2 ), 'GeeksForGeeks !' )
