Python Wand mode()用法及代碼示例

mode()函數是Python Wand ImageMagick庫中的內置函數，用於將每個像素替換為相鄰顏色的數學模式。

用法：

mode(width, height)

參數：該函數接受上麵提到的和下麵定義的兩個參數：

width:此參數用於存儲要包含在模式中的相鄰像素的數量。
height:這是一個可選參數，用於存儲相鄰像素的高度。默認情況下，它與寬度相同。

返回值：此函數返回Wand ImageMagick對象。

範例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 mode:
        # Invoke mode function with width as 30 and height as 10 
        mode.mode(30, 10) 
        # Save the image 
        mode.save(filename ='mode1.jpg')

輸出：

範例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 mode function with width and height as 200 
        pic.mode(200) 
        # Save the image  
        pic.save(filename ='mode2.jpg')
