更改特定像素的颜色[棒] [英] Change color of specific pixels [Wand]

问题描述

因此，我正在使用魔杖Python库来处理一些图像.

So, I'm using Wand Python Library to mess around with some images.

我只希望它逐个像素地查看图像，对于特定颜色的每个像素(例如"4d4d4d")，将该像素颜色替换为其他颜色，例如#00ff00".而已. 我已经对文档进行了彻底的搜索，但我终生无法弄清楚该怎么做.

I just want it to look at an image, pixel by pixel, and for each pixel that is a specific color, say '4d4d4d', replace that pixels color to something else, like '#00ff00'. That's it. I've thoroughly scoured the documentation and I can't for the life of me figure out how to do this.

推荐答案

如果有人感兴趣，那么python代码将是这样的:

If anyone is interested the python code would be something like this:

from wand.image import Image
from wand.drawing import Drawing
from wand.color import Color

with Drawing() as draw:
    draw.fill_color = Color('#00ff00')
    draw.color(x,y,'replace')
    with Image(filename='image.jpg') as img:
        draw(img)
        img.save(filename='new_image.jpg')
