point()是另一種繪圖函數,並且最簡單。 point()函數本質上在圖像的特定點上繪製一個點。它隻需要兩個x,y參數作為點坐標。
用法:
wand.drawing.point(x, y)
參數:
參數 | 輸入類型 | 描述 |
---|---|---|
x | numbers.Real | 點的x坐標 |
y | numbers.Real | 點的y坐標 |
範例1:
# Import different modules of wand
from wand.image import Image
from wand.drawing import Drawing
from wand.color import Color
# object for Drawing
with Drawing() as draw:
x = 100
y = 100
# draw point at (100, 100) using point() function
draw.point(x, y)
with Image(width = 200, height = 200,
background = Color('lightgreen')) as image:
draw(image)
image.save(filename ="point.png")
輸出:
範例2:
# Import different modules of wand
from wand.image import Image
from wand.drawing import Drawing
from wand.color import Color
import math
with Drawing() as draw:
for x in xrange(0, 200):
y = math.tan(x) * 4
# draw points at different locations using point() function
draw.point(x, y + 50)
with Image(width = 200, height = 200, background = Color('lightgreen')) as image:
draw(image)
image.save(filename = "points.png")
輸出:
