使用 pillow 创建和编辑图像时出现错误 "attribute access"

Question

所以，我正在尝试创建一个用颜色填充的图像，然后显示它以进行调试。我用枕头创建了图像，将其设置为黑色或 rgb 中的 (0,0,0)，我循环浏览并用实际颜色填充图像，等等。但是后来我得到了一些我不知道的属性的错误'知道如何填写 python.

import cv2
import tkinter as tk
import copy
from PIL import Image
from tkinter import filedialog


colorwheel = Image.new('RGB', (1, 255*7), color='black')
     colorwheel = colorwheel.load()
     colorwheel[0,1]=(255,255,0)
     colorwheel[0,2] = (255, 255, 0)
     r=255
     g=255
     b=0
     #keep value of green, add take away red
     for i in range( 255):
          colorwheel[0, i] = (255-1, 255, 0)


     #go to blue take away green
     for i in range( 255):
          colorwheel[0,255*2 + i] = (0, 255-i,0+1)

     #go to purple 128 keep blue, add red to 128
     for i in range (255):
          colorwheel[0, 255*3 + i] = (int(i/2), 0, 255)

     #go to red
     for i in range( 255):
          colorwheel[0,255*4 + i]=(int(i/2),0,255-i)

     #go to orange
     for i in range(255):
          colorwheel[0, 255 * 5 + i] = (128, int(i / 2), 0) #keep red 128


     for i in range(255):
          colorwheel[0, 255 * 6 + i] =(128,int(128+i/2),0)



     colorwheel.resize((50,255*7))
     cv2.imshow('image', colorwheel)

它应该具有调整大小和显示图像所需的一切，但我明白了。

File "C:/Users/misterE/PycharmProjects/frame2cc/base contraster", line 64, in <module>
    colorwheel.resize((50,255*7))
AttributeError: 'PixelAccess' object has no attribute 'resize'

Answer 1

根据 Pillow docs，PixelAccess 似乎没有函数 resize()。

如果您要调整图片大小，this post about resizing an image using PIL 可能会有用！

Answer 2

尝试：-

import cv2
import tkinter as tk
import copy
from PIL import Image
from tkinter import filedialog


colorwheel1 = Image.new('RGB', (1, 255*7), color='black')
colorwheel = colorwheel1.load()
colorwheel[0,1]=(255,255,0)
colorwheel[0,2] = (255, 255, 0)
r=255
g=255
b=0
#keep value of green, add take away red
for i in range( 255):
     colorwheel[0, i] = (255-1, 255, 0)

 #go to blue take away green
for i in range( 255):
     colorwheel[0,255*2 + i] = (0, 255-i,0+1)

 #go to purple 128 keep blue, add red to 128
for i in range (255):
     colorwheel[0, 255*3 + i] = (int(i/2), 0, 255)

#go to red
for i in range( 255):
     colorwheel[0,255*4 + i]=(int(i/2),0,255-i)

#go to orange
for i in range(255):
     colorwheel[0, 255 * 5 + i] = (128, int(i / 2), 0) #keep red 128


for i in range(255):
     colorwheel[0, 255 * 6 + i] =(128,int(128+i/2),0)



colorwheel1.resize((50,255*7))
colorwheel1.show()

输出图像：-

您出错的原因是，您试图在 PixelAccess 元素上使用 Image 对象命令 (Image.resize())。这导致了这个错误。为了解决这个问题，我们只是将原始 Image 对象的名称更改为 colorwheel1，以便我们可以进一步使用该对象来调整大小。

P.S.:- 最后我用 Image.show() 来显示图像而不是 cv2.imshow().
