推荐答案

Jpg是一种压缩格式-也是一种有损格式.这意味着您打开的.JPG文件不包含原始文件中的所有信息，因为创建jpg时它会丢弃一些信息.因此，如果您的原始文件是一个位图，该位图分别存储每个像素，则jpg将平均"一个像素块并仅存储该平均值.

返回到原始图像的唯一方法是打开原始图像而不是jpg文件.

Jpg is a compressed format - and a lossy one at that. Which means that the .JPG file you open does not contain all the information that was in the original as it throws away some information when the jpg is created. So if your original file was a Bitmap, which stores every pixel individually, a jpg would "average" a block of pixels and store just that averaged value.

The only way to get back to exactly the original image, is to open the original image instead of the jpg file.
