Python Wand remap()用法及代码示例

重映射效果将所有像素替换为在亲和力参考图像中找到的最接近的匹配像素。 remap()用给定的亲和力图像重建最接近颜色的调色板。

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

参数：

参数	输入类型	描述
affinity	BaseImage	参考图片。
method	basestring	抖动方法。参见DITHER_METHODS。默认值为‘no’抖动。

范例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")

输出：
