Question

我制作了一个程序，它正在拍摄我上传的图像并将其划分为象限，以不同方式混淆每个图像中的颜色。我的问题是我无法看到这个部门正确。

import cImage as image

img = image.Image("/home/users/groth1/Downloads/selfie.JPG")

newimg = image.EmptyImage(img.getWidth(), img.getHeight())

win = image.ImageWin(title="Pic",width=img.getWidth(),height=img.getHeight())

for row in range(img.getHeight(0,186)):  #Negative Q1
    for col in range(img.getWidth(0,325)):
       p = img.getPixel(col, row)

    newred = 255 - p.getRed()
    newgreen = 255 - p.getGreen()
    newblue = 255 - p.getBlue()

    newpixel = image.Pixel(newred, newgreen, newblue)

    img.setPixel(col, row, newpixel)

当我运行它时（使用介绍代码引入图像和所有这些）我得到一个错误，说“TypeError：getHeight（）需要1个位置参数但是3个被给出” 那是什么意思？我该如何解决？

该错误消息意味着函数cImage.Image.getHeight和cImage.Image.getHeight意味着在没有任何位置参数的情况下被调用。它们只返回图像的高度和宽度。通过传递0，186和325，我无法理解您要实现的目标。以下是关于如何修复代码的想法：

xQuadrantBoundary = img.getWidth()//2
yQuadrantBoundary = img.getHeight()//2

for row in range(img.getHeight()):  #Negative Q1
    for col in range(img.getWidth()):
        p = img.getPixel(col, row)

        if row < yQuadrantBoundary:
            if col < xQuadrantBoundary:
                # Change this to what you want to happen to the colors in the upper left
                newred = 255 - p.getRed()
                newgreen = 255 - p.getGreen()
                newblue = 255 - p.getBlue()
            elif col >= xQuadrantBoundary:
                # Change this to what you want to happen to the colors in the upper right
                newred = 255 - p.getRed()
                newgreen = 255 - p.getGreen()
                newblue = 255 - p.getBlue()
        elif row >= yQuadrantBoundary:
            if col < xQuadrantBoundary:
                # Change this to what you want to happen to the colors in the lower left
                newred = 255 - p.getRed()
                newgreen = 255 - p.getGreen()
                newblue = 255 - p.getBlue()
            elif col >= xQuadrantBoundary:
                # Change this to what you want to happen to the colors in the lower right
                newred = 255 - p.getRed()
                newgreen = 255 - p.getGreen()
                newblue = 255 - p.getBlue()

        newpixel = image.Pixel(newred, newgreen, newblue)

        img.setPixel(col, row, newpixel)
