Python Wand remap()用法及代碼示例

重映射效果將所有像素替換為在親和力參考圖像中找到的最接近的匹配像素。 remap()用給定的親和力圖像重建最接近顏色的調色板。

用法： wand.image.remap(affinity, method)

參數：

參數	輸入類型	描述
affinity	BaseImage	參考圖片。
method	basestring	抖動方法。參見DITHER_METHODS。默認值為‘no’抖動。

範例1：

# Import Image from wand.image module 
from wand.image import Image 
  
with Image(filename ="koala.jpeg") as left:
    with left.clone() as right:
        with Image(width = 100, height = 1, pseudo ="plasma:") as affinity:
  
            # remap image using remap() function 
            right.remap(affinity) 
        left.extent(width = left.width * 2) 
  
        # adding remaped image with original image 
        left.composite(right, top = 0, left = right.width) 
    left.save(filename ="remapk.jpeg")

輸出：
