像MS Paint一样调整位图大小 - 没有抗锯齿

 ```python

 from PIL import Image

 image = Image.open('input.bmp')

 resized_image = image.resize((new_width, new_height), resample=Image.NEAREST)

 resized_image.save('output.bmp')

 ```

 ```javascript

 const canvas = document.createElement('canvas');

 const context = canvas.getContext('2d');

 const image = new Image();

 image.onload = function() {

   canvas.width = newWidth;

   canvas.height = newHeight;

   context.imageSmoothingEnabled = false;

   context.drawImage(image, 0, 0, newWidth, newHeight);

   const resizedImage = canvas.toDataURL('image/png');

   // 处理调整后的图像

 };

 image.src = 'input.png';

 ```
