压缩图像文件格式(jpeg,PNG,gif)的原始形式是什么?(What is the raw form of a compressed image file format(jpeg, PNG , gif)?)
我们知道jpeg,PNG,gif都是压缩文件格式,我的问题是我们为这些压缩算法提供的原始输入源是什么,以及在将图像数据转换为这些文件格式之一之前存储的形式。
As we know jpeg , PNG , gif are all compressed file formats, my question is what is the original source of input we provide to these compression algorithms and in which form a image data is stored before it gets converted into one of these file formats.
