使用wand.drawing.Drawing,您需要構建繪圖對象的“上下文”.可以通過直接在繪圖對象實例上設置屬性來定義字體樣式,族,系列,顏色等等.

from wand.image import Image

from wand.color import Color

from wand.drawing import Drawing

from wand.display import display

with Image(width=200, height=150, background=Color('lightblue')) as canvas:

with Drawing() as context:

context.fill_color = Color('orange')

context.stroke_color = Color('brown')

context.font_style = 'italic'

context.font_size = 24

context.text(x=25,

y=75,

body="Hello World!")

context(canvas)

canvas.format = "png"

display(canvas)

但是如果你的繪圖對象已經有了矢量屬性呢？

這是Drawing.push()& Drawing.pop()可用于管理您的圖紙堆棧.

# Default attributes for drawing circles

context.fill_color = Color('lime')

context.stroke_color = Color('green')

context.arc((75, 75), (25, 25), (0, 360))

# Grow context stack for text style attributes

context.push()

context.fill_color = Color('orange')

context.stroke_color = Color('brown')

context.font_style = 'italic'

context.font_size = 24

context.text(x=25,

y=75,

body="Hello World!")

# Return to previous style attributes

context.pop()

context.arc((175, 125), (150, 100), (0, 360))
