从静态图像创建动画gif

Question

我有一组RGB值。我需要将它们放在单个像素中。我使用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 进行了此操作，但是我需要一张一张地绘制像素并查看进度，而不是获取最终图像。

import { Injectable } from '@angular/core';
import { CanActivate, ActivatedRouteSnapshot, RouterStateSnapshot, Router } from '@angular/router';
import { Observable } from 'rxjs';
import { map } from 'rxjs/operators';
import { AmplifyService } from 'aws-amplify-angular';

@Injectable({
  providedIn: 'root'
})
export class PrivateGuard implements CanActivate {

  constructor (private _router: Router,
               private _amplifyService: AmplifyService) {}

  canActivate(next: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<boolean> | Promise<boolean> | boolean {
    return this._amplifyService.authStateChange$.pipe(map(authState => {
        console.log(authState);
        if (authState.state === 'signedIn')  {
          return true;
        }else{
          this._router.navigate(['/login']); // Why Never redirect?
          return false;
        }
      })
    );
  }
}

您可以生成以下内容：

具有以下代码（对于numpy提示，@x Smarkell）：

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)

或者这个：

具有以下代码：

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)
