Python Wand shade()用法及代码示例

shade()函数是Python Wand ImageMagick库中的内置函数，该函数用于通过模拟高角度的光线来生成3D效果。

用法：

shade(gray, azimuth, elevation)

参数：该函数接受上面提到的和下面定义的三个参数：

gray:这是一个布尔参数，用于存储隔离效果。默认值为“ False”。
azimuth:此参数存储与x轴的夹角。
elevation:此参数存储与z轴成的角度量。

返回值：此函数返回Wand ImageMagick对象。

范例1：

# Import library from Image  
from wand.image import Image 
  
# Import the image 
with Image(filename ='../geeksforgeeks.png') as image:
    # Clone the image in order to process 
    with image.clone() as shade:
        # Invoke shade function 
        shade.shade(True, 10, 15) 
        # Save the image 
        shade.save(filename ='shade1.jpg')

输出：

范例2：

# Import libraries from the wand   
from wand.image import Image 
from wand.drawing import Drawing 
from wand.color import Color 
  
with Drawing() as draw:
    # Set Stroke color the circle to black 
    draw.stroke_color = Color('black') 
    # Set Width of the circlw to 2  
    draw.stroke_width = 1
    # Set the fill color to 'White (# FFFFFF)' 
    draw.fill_color = Color('white') 
  
    # Invoke Circle function with center at 50, 50 and radius 25 
    draw.circle((200, 200), # Center point 
                (100, 100)) # Perimeter point 
    # Set the font style 
    draw.font = '../Helvetica.ttf'
    # Set the font size  
    draw.font_size = 30
      
    with Image(width = 400, height = 400, background = Color('# 45ff33')) as pic:
        # Set the text and its location 
        draw.text(int(pic.width / 3), int(pic.height / 2), 'GeeksForGeeks !') 
        # Draw the picture 
        draw(pic) 
        # Invoke shade function method  
        pic.shade(False, 15, 15) 
        # Save the image  
        pic.save(filename ='shade2.jpg')

输出：
