我有一组RGB值。我需要把它们放在单个像素。我这样做有PIL
,但我需要一个绘制像素之一,看进度,而不是得到的最终图像。
from PIL import Image
im = Image.open('suresh-pokharel.jpg')
pixels = im.load()
width, height = im.size
for i in range(width):
for j in range(height):
print(pixels[i,j]) # I want to put this pixels in a blank image and see the progress in image
您可以生成这样的事情:
用下面的代码(THX @马克瑟特查为numpy
提示):
import imageio
import numpy as np
from PIL import Image
img = Image.open('suresh-pokharel.jpg')
pixels = img.load()
width, height = img.size
img2 = Image.new('RGB', img.size, color='white')
pixels2 = img2.load()
i = 0
images = []
for y in range(height):
for x in range(width):
pixels2[x, y] = pixels[x, y]
if i % 500 == 0:
images.append(np.array(img2))
i += 1
imageio.mimsave('result.gif', images)
或这个:
用下面的代码:
import random
import imageio
import numpy as np
from PIL import Image
img = Image.open('suresh-pokharel.jpg')
pixels = img.load()
width, height = img.size
img2 = Image.new('RGB', img.size, color='white')
pixels2 = img2.load()
coord = []
for x in range(width):
for y in range(height):
coord.append((x, y))
images = []
while coord:
x, y = random.choice(coord)
pixels2[x, y] = pixels[x, y]
coord.remove((x, y))
if len(coord) % 500 == 0:
images.append(np.array(img2))
imageio.mimsave('result.gif', images)
