path_curve() is a function specially introduced for paths. path_curve() draws a cubic bezier curve from the destination point of the Image to a particular point (x, y) with the help of control points.
Syntax :
wand.drawing.path_curve(to, controls, smooth, relative)Parameters:
Parameter Input Type Description to sequence or (numbers.Real, numbers.Real) pair which represents coordinates to drawn to. controls collections.abc.sequence or (numbers.Real, numbers.Real) coordinate to used to influence curve smooth bool assume last defined control coordinate relative bool treat given coordinates as relative to current point.
Example #1:
Python3
from wand.image import Image
from wand.drawing import Drawing
from wand.color import Color
with Drawing() as draw: draw.stroke_width = 2
draw.stroke_color = Color( 'black' )
draw.fill_color = Color( 'white' )
draw.path_start()
# Start middle-left
draw.path_move(to = ( 10 , 100 ))
# Curve across top-left to center
draw.path_curve(to = ( 80 , 0 ),
controls = [( 20 , - 80 ), ( 60 , - 80 )],
relative = True )
# Continue curve across bottom-right
draw.path_curve(to = ( 80 , 0 ),
controls = ( 60 , 80 ),
smooth = True ,
relative = True )
draw.path_finish()
with Image(width = 200 , height = 200 , background = Color( 'lightgreen' )) as image:
draw(image)
image.save(filename = "pathcurve.png" )
